CCTV News:Recently, the word "plague" has touched the sensitive nerves of the public. Infectious diseases spread through respiratory tract make people unprepared, and tuberculosis is one of them. "The harm of tuberculosis to human beings, even the most terrible infectious diseases, such as plague and cholera, should be listed next." Robert koch (1843-1910), winner of the Nobel Prize in Medicine and Physiology and discoverer of tuberculosis, once counted that in Europe at that time, one out of every seven people would die of tuberculosis. Today, tuberculosis, an ancient disease, is still one of the top ten fatal diseases in the world, and it has been the first cause of death of a single infectious disease since 2007. The United Nations Agenda for Sustainable Development in 2030, which was launched in 2016, proposes to end the epidemic of tuberculosis by 2030.

　　In recent years, China has made great progress in the prevention and control of tuberculosis, and the burden of tuberculosis has dropped significantly, achieving the United Nations Millennium Development Goals five years ahead of schedule. However, as a key area of tuberculosis, China has about 900,000 new cases every year. According to the estimation in 2018, the number of new cases of tuberculosis in China is 866,000, which is more than 20,000 fewer than that in 2017, ranking 28th among 30 countries with high burden of tuberculosis. In June 2019, the National Health and Wellness Commission and other eight departments jointly issued the Action Plan to Stop Tuberculosis (2019-2022), proposing that by 2022, the incidence of tuberculosis in China will drop from 59.3/100,000 in 2018 to 55/100,000, and the mortality rate will remain below 3/100,000. China will further improve TB prevention and control measures and accelerate the implementation of its international commitment to stop TB.

　　Preventive treatment is the key to the global latent tuberculosis infection population of about 1.7 billion.

　　Tuberculosis has not been eradicated for so long because of its unique transmission and pathogenic mechanism. Autumn and winter are the periods of high incidence of tuberculosis. A "sneeze" on a bus or subway car may make you a latent tuberculosis infection. What are the reasons?

　　When an active tuberculosis patient spits, coughs or sneezes, droplets can directly enter the alveoli of normal people. Pathogenic mycobacterium tuberculosis can invade alveoli and reproduce in the nucleus of macrophages it contacts. Blood circulation can bring infection to other remote parts of the body, such as peripheral lymph nodes, kidneys, brain and bones. It is worth noting that the latent infection of mycobacterium tuberculosis is asymptomatic, but there is a 10% chance of developing into an active patient in his life. According to the "Global Tuberculosis Report 2019" released by the World Health Organization, there are about 1.7 billion people with latent tuberculosis infection in the world, accounting for about a quarter of the whole population.

　　There is a saying widely circulated in the medical field: I got AIDS, but I died of tuberculosis. It is understood that AIDS patients, especially those without drug protection, have a 20 times higher incidence of tuberculosis than ordinary people. According to related literature, tuberculosis patients can infect 10-15 people through close contact in one year. If not treated properly, up to two-thirds of tuberculosis patients will lose their lives.

　　At present, the known high-risk factors that promote latent tuberculosis to develop into active tuberculosis include: close contacts of active tuberculosis patients, organ transplantation, HIV infection, diabetes, pneumoconiosis, low immunity, use of immunosuppressive drugs and so on. People with high risk factors should be targeted for screening, and preventive treatment should be given in time if latent infection is found.

　　Vaccines may completely eliminate an infectious disease. Not long ago, at the 50th Global Lung Health Conference held in Hyderabad, India, GlaxoSmithKline and International AIDS Vaccine Action announced the IIb clinical research results of a new tuberculosis vaccine candidate. The data showed that the vaccine significantly reduced the incidence of tuberculosis in HIV-negative adults with latent tuberculosis infection, and the total efficacy of the vaccine was 50% within 3 years after vaccination. Faced with this data, people in the industry have different opinions. Domestic experts attending the meeting said that in the face of the incidence of tuberculosis in China, which is about 60 per 100,000, it is more significant to block the onset of infected people’s vaccines than to prevent infection. However, at present, the research and development of this new candidate vaccine has a long way to go from clinical phase II to real use in healthy people.

　　Compared with the complicated research and development of tuberculosis vaccine, it seems that new diagnostic tools, new drugs and new strategies can boost people’s spirits.

　　Ten-year change from 13 pills a day to 3 pills for comprehensive prevention and control of tuberculosis

China has continuously increased its investment in tuberculosis prevention and control.

　　"In 2008, Melinda and I visited several tuberculosis patients in a village in Hainan, and one of the female patients showed me the 13 pills she needed to take that day. The process of taking medicine is very complicated. From then on, I began to pay attention to tuberculosis in China. " Not long ago, Bill Gates told a story about the "medicine box" at the 10th anniversary seminar of the National Health Commission-Gates Foundation tuberculosis prevention and treatment project.

　　For tuberculosis patients, as long as they can take enough medicine for a long time, they can recover. But the problem is that after one or two months of treatment, patients’ symptoms are relieved, and they feel that they are already well, and some will stop taking drugs on their own. In this way, the patient’s condition may be repeated, and it may develop into drug-resistant tuberculosis. From this point of view, the situation of tuberculosis prevention and control is still very grim, and countries with high burden of tuberculosis are exploring and innovating in technology and prevention and control strategies.

　　Before 1991, China’s disease prevention and control institutions at all levels were the main responsible institutions for tuberculosis prevention and control. In 1991, the former Ministry of Health issued the Measures for the Prevention and Control of Tuberculosis, which also included the designated medical prevention and health care institutions in the management of tuberculosis prevention and control business. Since 2009, the National Health and Wellness Commission has cooperated with the Gates Foundation to carry out the tuberculosis prevention and control project, aiming at constructing and implementing a new prevention and control model for tuberculosis and multi-drug resistant tuberculosis, and improving the quality of tuberculosis prevention and control in China, especially multi-drug resistant tuberculosis. Under the leadership of the National Health and Wellness Commission, through the joint efforts of both parties, the project has been explored and implemented in three stages in the past decade, and an operable, sustainable and reproducible comprehensive prevention and treatment model for tuberculosis has been established.

　　From 2016 to 2019, the China-Gai TB Prevention and Control Project has comprehensively promoted the comprehensive prevention and control model in Zhejiang, Jilin and Ningxia provinces, covering a population of 90 million, helping the three provinces to achieve the main indicators of the 13 th Five-Year Plan for TB Prevention and Control ahead of schedule, and the disease prevention and control effects and social effects have been manifested.

The incidence of tuberculosis in China is decreasing year by year.

　　Ten years ago, it took two months to diagnose drug-resistant tuberculosis, but now it takes only two hours to use new technology; Ten years ago, tuberculosis patients needed to take 13 pills a day, but now they only need to take 3 pills; Under the traditional second-line drug treatment, the average cure rate of drug-resistant tuberculosis is about 50%, but now, due to the new drugs introduced by the project, the preliminary results show that the cure rate of patients can be improved to 85%; Thanks to the government’s measures such as increasing special investment in tuberculosis and multi-sector financing, the individual’s contribution to the medical expenses of drug-resistant patients now does not exceed 10%. Continue to increase the central financial input, new diagnostic tools and new technologies emerge one after another, and constantly improve tuberculosis prevention and control strategies and intervention measures.

　　The future of drug-resistant tuberculosis patients

Indian community women’s organizations are committed to promoting tuberculosis prevention and treatment.

　　The troubles of reality often have nothing to do with technology itself.

　　October 27, 2019 is the traditional festival of Diwali (Indian New Year) in India. For local people, this is the most grand day of the year. For the Samiri family, this new year is worth celebrating. Because her brother Johnny, who suffered from MDR-TB, was discharged before the New Year! This also means that Johnny has stood at a new starting point in the treatment of tuberculosis. Although the obstacles are long, he said that he will stick to it.

　　18 years ago, Samiri and Johnny’s father died of tuberculosis, when Samiri was only 6 years old. Two years ago, tuberculosis invaded her body, followed by her brother … … In India, the incidence and death of tuberculosis and the number of patients with rifampicin (first-line anti-tuberculosis drug) resistant tuberculosis all rank first among the 30 countries with high burden of tuberculosis in the world, while China ranks second in the global proportion of new cases. At the same time, the number of patients with rifampicin-resistant tuberculosis in China ranks second in the world after India.

　　According to a report released by the World Health Organization in 2019, there were about 39,400 deaths due to tuberculosis in China in 2018. Then, how to further accelerate the containment of tuberculosis has become a common problem for countries with high burden of tuberculosis, such as India and China.

　　"Under the traditional second-line drug treatment, the cure rate of drug-resistant tuberculosis is about 50% on average. Because of the addition of new drugs in the scheme and the first new drug for tuberculosis in 50 years, the cure rate of patients has been greatly improved," said Gao Mengqiu, director of the Second Department of Tuberculosis, Beijing Chest Hospital affiliated to Capital Medical University.

　　It should not be ignored that according to the WHO report in 2019, in 2018, the proportion of new patients in China who were resistant to multidrug and rifampicin was 7.1%; The rate of multidrug resistance and rifampicin resistance in retreatment patients was 21%.

　　New drugs and drug resistance are twins. It is inevitable that drug resistance will occur with new drugs. "It is said that the drug resistance of betaquinoline has reached 8% in some countries." Li Liang, vice president of Beijing Chest Hospital affiliated to Capital Medical University, said that if drug use is not standardized, new drug resistance will soon form. He called for a protection mechanism for some new drugs to reduce or delay the emergence of drug resistance. He also revealed to reporters that for drug-resistant tuberculosis, the diagnosis and treatment norms will be introduced in the near future.

　　At the first special session of the 50th World Congress on Lung Health in China, the progress of innovative technologies of tuberculosis immunization prevention, detection, artificial intelligence screening and diagnosis in China became the core topic, and five innovative enterprises in China shared the new technologies and progress of tuberculosis research independently developed. "China needs to adapt to local conditions and have its own unique things to end tuberculosis." Li Liang said that the key is to do a good job in capacity building, on the one hand, strengthen the quality monitoring of clinical trials, on the other hand, strengthen the information construction. China has a huge patient population and a good "national team" — — "Trinity" TB prevention and control system, which is incomparable in any country in the world.

　　Some experts said that if the 1940s and 1960s were a golden decade for the invention of tuberculosis drugs, then from now on, we will enter a new golden age. It remains to be seen how long this golden age can last.

Along Tianfu Avenue, the central axis of Chengdu, all the way to the south, there are rows of tall buildings. Next to Tianfu Avenue, Tianfu Central Legal District, with Tianfu Central Business District as the main bearing place, was officially launched on February 5.

Last year, the Provincial Party Committee decided that the Political and Legal Committee of the Provincial Party Committee would take the lead in planning and constructing the Tianfu Central Legal District in Chengdu, Tianfu New District. This is the first modern legal gathering area promoted at the provincial level in China. At present, more than 20 institutions have settled in in advance, and many projects are being promoted.

Why should Sichuan build Tianfu Central Legal District? How to build?

Why build it?

Optimize the business environment ruled by law

On the day when Tianfu Central Legal District was put into operation, Beijing Tongshang (Chengdu) Law Firm signed a cooperation agreement as a representative of the legal service agency.

"Trading" is evaluated by the industry as one of the "red circle offices" of top law firms. "It was established in Beijing in 1992, and by 2000, we only set up branches in Shanghai and Shenzhen. Chengdu Branch is the first branch established by’ Trade’ 20 years later, and it values the future development prospects of Sichuan. " Nathan Chen, senior partner of the Beijing headquarters of the law firm, introduced.

"Supporting the construction of the Central Legal District in the Central Business District is of great significance for improving the level of public legal services and the rule of law, creating a good economic order and business environment, and promoting high-quality development." Cao Daixue, deputy secretary of the Political and Legal Committee of the Provincial Party Committee, said.

The staff responsible for attracting investment are deeply touched. "The economic center is a gathering place for economic resources, and it also needs the help of legal resources." According to the relevant person in charge of the Economic Bureau of Tianfu New District Headquarters, in the daily investment promotion work, some enterprises are very concerned about the legal environment and legal service supply capacity of the attracting places. "Every time we make a promotion, we will definitely take the rule of law business environment as an important display content."

Liu Zhicheng, director of the Department of Justice, said that Sichuan has basic conditions and urgent needs to build a central legal district.

"In recent years, Sichuan’s legal service industry has continued to develop, ranking first in the country and leading in the west. However, with the in-depth implementation of the "Belt and Road Initiative", the development of the western region, and the construction of the twin-city economic circle in Chengdu and Chongqing, there are shortcomings such as insufficient high-end industries in the Sichuan legal service industry. " Liu Zhicheng introduced that the construction of Tianfu Central Legal District will help to gather a group of branded and large-scale legal service institutions with benchmarking role in the whole country, and provide legal services for the internationalization of Sichuan and even the central and western regions in high-end service fields such as corporate business and financial securities.

Liu Zhicheng believes that as an important part of modern service industry, Sichuan legal service industry still has a lot of room for expansion and promotion. "The proportion of GDP in the legal service industry has exceeded 1% in Beijing and Shanghai, while Sichuan only accounts for 0.1%. The construction of Tianfu Central Legal District will open up space and provide a platform for the development of legal service industry in our province. "

How to build it?

Create a professional "rule of law ecosystem" in the whole chain

How to build Tianfu Central Legal District? The planning has a clear orientation and construction goal: to build a first-class legal service highland based in Sichuan, radiating to the west, affecting the whole country and facing the world.

The construction of "highland" cannot be separated from industrial support. The "Overall Implementation Plan for the Construction of Tianfu Central Legal District" led by the Political and Legal Committee of the Provincial Party Committee makes it clear that in terms of industrial planning, Tianfu Central Legal District will build a "rule of law ecosystem" of "platform-driven layer, core industry layer, related function layer and derivative supporting layer".

What is planned synchronously with the industrial layout is the spatial layout. Cao Daixue introduced that Tianfu Central Legal District will plan to form a spatial layout of "one heart, one belt and more points". "One heart" means the public legal service center; "One Belt" means the development belt of high-end legal service industry; "Multi-point" refers to a number of legal cultural communication nodes.

"After receiving the construction task, I immediately selected the legal service gathering areas of world-class cities such as the City of London and Manhattan, new york, and did a lot of empirical research. These legal service clusters show some common points, and in spatial form, there is a significant accompanying relationship with high-energy business districts; In terms of layout characteristics, it is relatively concentrated around the landmark landscape and along the rail transit. Therefore, the construction of Tianfu Central Legal District chooses Tianfu Central Business District as the main carrier and TOD as the center to build a high-end legal service industry development belt running through Tianfu Central Business District. " The above-mentioned person in charge of the Economic Bureau of Tianfu New District Headquarters introduced that in order to support the construction of Tianfu Central Legal District, Chengdu’s integrated design of Qingdao Road TOD site can be described as "finely crafted", and the surrounding industrial planning and supporting needs have been studied and demonstrated many times, and the requirements for the construction of the legal district that have been sorted out have been refined and improved.

"New District" construction, policy first. The reporter learned that the Justice Department has formulated the "Implementation Measures for Launching the Pilot Work of Law Firms Hiring Foreign Lawyers as Foreign Legal Advisers (Trial)", which will promote the exchange of Chinese and foreign lawyers and improve the level of foreign-related legal services in Sichuan. Tianfu New District will also give policy incentives to enterprises and talents who have settled in Tianfu Central Legal District from ten aspects, such as settlement incentives and lease subsidies, in order to attract high-end legal resources to gather in Tianfu Central Legal District.

How’s it going?

More than 20 institutions have settled in, and the siphon effect has begun to show.

On February 5, the comprehensive service center of Tianfu Central Legal District was opened simultaneously. This is the first carrier of Tianfu Central Legal District, and more than 20 institutions have been stationed in the first batch, including political and legal service window units, influential legal institutions such as lawyers, notaries, arbitrations, judicial expertise, market supervision, intellectual property rights, accounting and other legal institutions.

"This is one of the achievements of the current construction of Tianfu Central Legal District." According to the relevant person in charge of the comprehensive service center, the biggest feature of the center is to "only run one leg, only enter one door and only find one person" to achieve "one-stop" business handling.

The reporter learned from the Procuratorial Service Center of Tianfu Central Legal District that the center has set up windows for defense and agency reception, case acceptance and legal consultation, as well as an office area for intellectual property procuratorial classes and an enterprise service hall to perform some procuratorial functions of Sichuan Provincial People’s Procuratorate, Chengdu People’s Procuratorate and Tianfu New District People’s Procuratorate. "Here, through a window, the’ one-stop’ service of the three-level procuratorial organs in the province can be realized." The relevant person in charge of the provincial procuratorate introduced.

This layout makes the siphon effect of Tianfu Central Legal District appear. "Law firms need to deal with relevant legal institutions, which are relatively clustered and more convenient. In addition, institutions can promote each other and improve their business level in collaboration. " Nathan Chen said.

"The notarization accreditation center and the global digital legal notarization service platform we have set up here have been put into operation. The global digital notarization service platform can realize remote handling and can cooperate with foreign notaries and foreign legal institutions to handle notarization business through the network. " The relevant person in charge of the Sichuan Legal Notary Office said.

More planning is coming into reality. The provincial courts actively strive for the support of the Supreme People’s Court, and settle in the Chengdu District Court of Tianfu New District (Sichuan Free Trade Zone Court), the first and second courts of Chengdu railway transportation, the Chengdu Intellectual Property Court, the Chengdu Bankruptcy Court, the Chengdu Internet Court, the Chengdu Financial Court and the Giant Panda National Park Ecological Court in Tianfu Central Legal District. When conditions are ripe, the provincial courts and the Chengdu Intermediate People’s Court will also settle in to form a judicial gathering area.

The Department of Justice has won 19 policies and projects from the Ministry of Justice, and 17 were approved in advance. The Ministry of Justice has clearly expressed its support for the policy of striving for the introduction of international arbitration institutions, and will support the employment of international arbitrators as arbitrators in existing arbitration institutions, which will boost Chengdu to become a regional international arbitration center.

In the future, Tianfu Central Legal District has a higher construction goal-by 2030, it will form a high-energy industrial system that comprehensively covers and seamlessly connects the international and domestic legal service needs, continuously improve the incubation mechanism of international legal enterprises and the training mode of international legal talents, continuously export international leading legal service solutions, and become a rule of law platform with international influence.

Chip, optical fiber and optical cable are the hardware foundation of today’s information-based, intelligent and networked society, and electronic-grade quartz sand with purity of 99.999% is the basic raw material for manufacturing chip, optical fiber and optical cable. For a long time, China’s electronic grade quartz sand has relied on imports. Breaking the "ceiling" of 80% purity of domestic mainstream quartz sand, breaking foreign technical barriers and solving the "stuck neck" problem … Xie Dachun, technical director of Jiangsu Xinyiding Shi Ying Science and Technology Co., Ltd., did not stop, still buried himself in the laboratory all day, holding his sleeves, and continued to seek breakthroughs in quartz sand raw materials whose purity has reached the world’s top level.

"Ingenuity is the determination to break through and the patience to study."

On the afternoon of April 3rd, in the roasting workshop of Jiangsu Xinyiding Shi Ying Science and Technology Co., Ltd. in Shuyang County, Suqian City, a "big guy" connected with a huge water tank was rising with white steam, which was a "unique weapon" for enterprises to purify quartz sand. This reformed equipment led by Xie Dachun won the national invention patent.

In the purification process of quartz sand, many impurities are micron-sized and need to be treated by cold explosion. That is, using the principle of thermal expansion and cold contraction, high-temperature quartz sand is put into cold water to burst, so as to achieve the effect of separating impurities. However, as soon as the high-temperature quartz sand enters the water, the cold water becomes boiling water, and the effect of cold explosion is greatly reduced. Many domestic technical teams are stuck in the "cold explosion" level.

"In those years, I walked repeatedly in my mind to do simulation tests, and finally I had this machine." Xie Dachun said that a few years ago, he happened to pass by a popcorn stand. At that time, the sound of popcorn startled him, but it was this "bang" that reminded him of the solution of "cold explosion" technology from the production principle of popcorn. Then, he immediately rushed back to the company and took his colleagues to discuss. Finally, he invented the current dynamic roasting and cold explosion technology: in a quartz tube with a constant temperature of 930℃, Shi Ying blocks were continuously put in, and during the falling process, they were evenly heated to complete the cold explosion.

In the following years, Xie Dachun and the company constantly improved their equipment in the process of updating their production technology, and only the equipment for producing electronic-grade quartz sand was updated for more than ten times, finally achieving self-sufficiency of electronic-grade quartz sand.

The reporter noticed that there are not many operators in such an important roasting workshop, and a large number of operation links have been replaced by hanging rails and electric cranes. Workers only need to control them remotely. "This is also a bitter credit! In the traditional process, there is a great demand for workers in the roasting workshop, and at the same time, because of the high temperature, workers are easily burned if they are improperly operated, so the turnover rate is very high. " Wang Wei, the production director of the company, told the reporter that at that time, when the company was troubled by this "industry problem", Xie Dachun took the task without saying anything.

In the next three months, Xie Dachun "closed the door" in the workshop and kept researching and experimenting all day. There were more than 500 drawings drawn alone. After repeated experiments for more than 260 times, we finally found such a "machine substitution" method, which solved the production problem satisfactorily and thoroughly. Now this method has been widely used in the whole industry.

"I am a farmer, and I failed in the college entrance examination. Even when I entered the business, I only had some electrician foundation, so as long as I am willing to study, I can always find a solution to the problem." Xie Dachun told reporters that he is a veritable "soil expert". All scientific research achievements and invention patents were explored in workshops and laboratories, and this experience also reflected his understanding of "ingenuity": the determination to break through and the patience to study.

"Social terrorism" experts break the technical blockade

Xie Dachun has a dazzling "report card": in the past 30 years, he has won more than 20 national, provincial and municipal scientific and technological innovation achievement awards and science and technology awards, and has more than 100 invention patents and utility model patents, among which five scientific and technological achievements such as "domestic preparation technology of electronic quartz sand" have filled the domestic gap and reached the international advanced level.

Due to the particularity of the industry, electronic quartz sand is mainly used in high-tech fields such as semiconductors, electrical and electronics, aerospace, national defense and military industry. "For a long time, the purification technology of electronic grade quartz sand has been firmly stuck in foreign countries. Because of technical barriers, the previous domestic quartz sand products can only be used in some low-end products such as halogen lamps, and they can’t touch the threshold of high-end market at all." Director Wang Wei told the reporter that even the leading domestic companies, with the same foreign equipment, have only got the "admission ticket" to the high-end market, and for a long time, 80% of the purity of the domestic mainstream quartz sand products industry has been "ceiling".

Due to the high cost of R&D, many manufacturers have no choice but to give up and import from abroad at a high price of nearly 100 times after entering a "dead end" again and again, but Xie Dachun has been insisting.

"Increase 80% to 99%, and then increase the’ 9′ after the decimal point of 99.9% to three, five or even more, and each step will take three years or more to try and make mistakes." Liang Haidong, Xie Dachun’s apprentice, said that for this goal, Xie Dachun has become the most "social fear" person in the company: in the past 20 years, he has been eating and living in the laboratory, and rarely has any work-related communication with outsiders.

"Striving for Excellence and pursuing the ultimate" is a feature that Xie Dachun once exhorted and taught Liang Haidong more than once, and it is also the best embodiment of Xie Dachun’s "artisan spirit". With the ingenuity of this craftsman, he has endured loneliness for more than 20 years, and has successfully developed a number of high-efficiency, energy-saving and environmentally-friendly mechanical and electrical equipment. More than 20 new products have been widely used in high-tech fields such as semiconductor integrated circuits, aerospace satellite testing, and fiber-optic chip manufacturing for national defense and military industry.

In 2021, Jiangsu Xinyiding Company solved the purification problem of electronic grade quartz sand and became the only enterprise in China that can improve the purity of quartz sand to "six 9s".

Over the years, under his example, more than 300 people have grown into the technical backbone of Shi Ying products manufacturing industry and become a new force to promote technological innovation of enterprises in the industry.

The industrial craftsman "Jin Gangzuan" brought in income of nearly 3 billion yuan.

Replace the old baking oven with a new intelligent baking oven with automatic temperature control, popularize the use of frequency conversion governor for automatic speed regulation, and automatically control the continuous melting furnace with laser controller …

During the interview, Chen Qiong, general manager of Jiangsu Xinyiding Shi Ying Science and Technology Co., Ltd., pointed to the equipment in various production workshops from time to time and proudly told reporters that these were the results of the company’s independent research and development or improvement, most of which were attributed to Xie Dachun.

Ingenuity brings prosperity to all industries. "Every industrial craftsman is a’ Jin Gangzuan’ that will never change in the high-quality development of enterprises!" Chen Qiong sincerely said that thanks to Xie Dachun’s continuous technological innovation for many years, numerous innovations have brought direct or indirect benefits of nearly 3 billion yuan to enterprises, and its social and economic benefits are obvious to all.

In the development layout of enterprises in recent years, Jiangsu Xinyiding Shi Ying Science and Technology Co., Ltd. has invested heavily in its own scientific and technological innovation and project research and development, and successively acquired a number of surrounding enterprises. On the basis of lengthening the original industrial chain, it opened a separate research and development workshop, and appointed Xie Dachun to continue to set up a technology research and development team to strengthen the scientific research strength of enterprises and enhance their core competitiveness.

"Use new products and innovative technologies to save enterprises and reduce the burden on society." In Xie Dachun’s view, this is not only a technician’s obligation to society, but also an inevitable requirement for the development of modern industrial system. At this year’s National People’s Congress, new quality productivity and craftsman spirit have become hot topics together, and the close relationship between them is self-evident. He said that at present, it is an excellent stage for high-skilled talents to display their fists and feet, and he will also strive to lead his colleagues to forge a hard-working style of Excellence and diligent study, and strive to move closer to "knowledge-based, skilled and innovative" craftsmen in big countries.

Tang DM

Subsidized selling price: 239,900-329,900 yuan.

Pure electric cruising range: 80km/100km

● Model introduction

BYD’s new generation Tang DM is a model based on BYD BLP large luxury platform, which was officially launched in June this year. In fact, for Tang DM, everyone is familiar with it. Since the previous generation, its good acceleration ability has attracted many people’s attention, and this new generation of Tang DM not only inherits the excellent acceleration performance before, but also has a more beautiful face.

The appearance of the new generation of Tang DM can be said to have changed a lot from the old models. The car adopts the latest Dragon Face design language of the family, which makes the whole car look more spiritual. The large-mouth mesh makes the visual impact stronger, and at the same time, it is connected with the headlight group to highlight the overall sense. The whole system comes standard with LED headlights, which are sharp in style. The three LED headlights inside are very refreshing, and the visual effect of the running turn signal is also good. In addition to the lowest four-wheel drive Zhilian Chuangyue model, the whole system comes standard with adaptive far and near light. Behind the driver’s side is a gasoline filler. This 2.0T engine can meet the demand of 92 # gasoline without picking oil, and behind the co-pilot’s side is a charging interface. Officially, it takes five hours to fully charge the battery. Compared with the front of the car, the tail style looks more solid and not as exaggerated as the front of the car, but the suspended roof and the penetrating three-dimensional taillights enhance the design sense of the tail and look quite fashionable.

From the outside to the inside of the car, we can see that the overall design of the interior is very simple, and we can’t see too many physical buttons. The material on the center console feels fine, but it is not soft enough, and it has a general sense of advanced. However, the large rotatable multimedia screen in the center attracts people’s attention. At the same time, the functionality of this large screen is good, and the fluency of use is satisfactory. The functions such as air conditioning, sound and multimedia can be operated through this screen. In addition, it can also be used. Although the full LCD instrument is not a new product in this level of China brand SUV at present, the full LCD instrument on Tang DM is quite reasonable in layout, not messy, functional and convenient to look at. The steering wheel is comfortable to hold, and the size is appropriate. The shift lever has not adopted a new design, and there are physical buttons such as air conditioning and ESC off around it, which can improve the convenience of use accordingly.

In terms of space, Tang DM’s performance is not bad, and there will be no sense of oppression when sitting in it. For seven-seat vehicles, even if the rear seat is adjusted to the front, the leg space of the rear passengers will not be crowded, and the back of the rear seat can be adjusted back and forth. The headrest is arranged in the center, and the seat cushion is flat, and the floor projection is small, so the comfort of the passengers is still guaranteed. It’s no problem to take an adult of 170cm in the third row seat, especially if the second row seat is a little forward, then the third row passengers can be more comfortable.

The performance of the trunk is good and smooth. When the third row seat of the 7-seat model is activated, after putting a 24-inch suitcase, you can also put a schoolbag. When the third row seat is put away, the trunk is quite large, and the second row seat can be put down at a ratio of 4/6 to improve the space flexibility.

In terms of power, Tang DM, like the old models, is equipped with a 2.0T engine with a maximum power of 205 HP (151 kW) and a maximum torque of 320 Nm. However, in terms of electricity, the new car has been upgraded to some extent. First, a BSG motor has been added. By optimizing the electronic control management system, the new car has better economic capacity than the old model. In addition, with a front-axle motor with a maximum power of 110kW (150 HP) and a maximum torque of 250 Nm and a rear-axle motor with a maximum power of 180kW (245 HP) and a maximum torque of 380 Nm, the whole hybrid system can explode with a maximum torque of 950 Nm. In terms of battery configuration, Tang DM provides 80 and 100 configurations, of which the total energy of the power battery of Tang DM 80 model is 20kWh and the cruising range of pure electricity is 80 kilometers; The total energy of the power battery of the DM 100 model of Tang Dynasty is 24kWh, and the cruising range of pure electricity is 100 kilometers. In terms of charging time, both of them can be fully charged in 4-5 hours. The ATS all-terrain system of the car can provide five driving modes, namely energy saving, sports, sand, mud and snow.

Judging from car home’s measured acceleration performance of Tang DM, the acceleration ability of 0-100km/h in 4.7 seconds can be said to be very conspicuous, and it is completely driven by motor at the beginning, and the whole acceleration process has a strong sense of pushing back. In the pure electric mode, when the power is sufficient, the engine will not start even if the accelerator is stepped on deeply, and the whole driving process is very quiet, and the vehicle is completely driven by pure electricity. In hybrid mode, it will definitely not be as quiet as pure electric mode, and the engine will bring some vibration and noise, but the overall noise control is good and will not give you obvious feelings. There is no virtual position in the steering, and the accuracy is quite high. The suspension supports the car body in place, and the roll is not big when the car is cornered at a faster speed.

● Recommended models

There are 7 models of BYD Tang DM, of which the full-time four-wheel drive Zhilian Chuangshi Edition sells for more than 300,000 yuan after subsidy, which is out of our recommended range. Of the remaining 6 models, 4 are pure electric vehicles with a battery life of 80km, and the remaining 2 are pure electric vehicles with a battery life of 100km. Among the models with a battery life of 80km, only the full-time four-wheel drive Zhilian Chuangxiang model with a subsidized price of 254,900 is a 5-seat version, because if you want to buy a model with a battery life of 80km and want to choose a 5-seat version, you can only buy this model. Among the 7-seat models with a pure electric battery life of 80km, the most recommended model is the 259,900 full-time four-wheel drive Zhilian Chuangxiang model. Compared with the full-time four-wheel drive Zhilian Chuangrui model, the car is 10,000 higher, and it is worthwhile to add 360-degree panoramic images, 12.3-inch full LCD instruments, front seat heating/ventilation, and interior atmosphere lights. If you want to choose a five-seat version with a pure electric cruising range of 100km, you can only choose a full-time four-wheel drive Zhilian collar model with a subsidized price of 274,900. If you choose a 7-seat version with a pure battery life of 100km, it is recommended to create a full-time four-wheel drive Zhilian collar.

Summary:

As a medium-sized plug-in SUV that entered the new energy market earlier, the change of the new generation of Tang DM is quite thorough, and both the appearance design and the power electronic control system are satisfactory. At the same time, in terms of configuration and practicality, the car is also in place and can meet the needs of most users.

WEY P8

Subsidized selling price: 244,800-279,800 yuan.

Pure electric cruising range: 50km

● Model introduction

WEY P8 is the first plug-in hybrid four-wheel drive SUV launched by WEY, a brand of Great Wall, which was officially launched in April this year. The new car is built on the new WEY Pi4 platform, and the overall design style is basically consistent with VV7, which is quite dynamic. Let’s take a closer look.

WEY P8 continues the design language of VV7 in appearance, but it has been adjusted in details. The exaggerated integral net looks more exaggerated than VV7. The driver’s left front fender is equipped with a charging interface, which takes up to 4 hours to fully charge the battery. The Pi4 logo behind the interface represents WEY’s plug-in four-wheel drive platform. There is little difference between the design of the car side and the rear of the car and WEY VV7, and the design of the rear of the car is still very dynamic. Although P8 is a hybrid car, it is also equipped with bilateral exhaust, which looks very handsome. The rear of the car on the co-pilot side is the fuel tank cover, so it is enough to fill with 92 # gasoline.

The interior design is basically the same as VV7, but because of its special status as a new energy source, some specific settings have been made on the function buttons. Sitting in the car, whether it is above or below the center console, all of them are wrapped in soft materials, which feels very delicate. The full LCD instrument panel is familiar to everyone. The functions are clearly displayed, the layout is clear, and it is quite convenient to use. By the way, the tachometer originally on VV7 has been converted into a power meter. The multimedia screen on the center console can display the schematic diagram of power output, and at the same time, through this screen, you can set the vehicle reservation charging, low-speed virtual engine sound and energy recovery. A knob is set below the center console, which can switch between AUTO mode, EV mode, SAVE mode and SPORT mode. At the same time, after pressing the middle AWD, three all-terrain modes can be selected: snow, mud and sand.

The performance of WEY P8 in space is not ideal, because of the overall shape, the head space of the rear passengers is somewhat depressed. Fortunately, the comfort of the front and rear seats is good, the cushion is quite thick, and the wrapping and support of the backrest are satisfactory. The space of the trunk is somewhat unsatisfactory. Originally, due to the modeling reasons, the volume of the trunk will be affected. In addition, the battery pack is inside the trunk, which further reduces its volume. Fortunately, the rear seats can be folded 4/6, which can expand the storage capacity.

In terms of power, WEY P8 is equipped with an engine with a maximum power of 340 HP (250 kW) and a maximum torque of 542 Nm. This engine is exactly the same as the one on VV7. In addition, it is equipped with a 15 kW BSG auxiliary belt starter motor and an 85 kW TM drive motor. TM drive motor can drive the rear wheels independently, thus realizing electric four-wheel drive. The car has a combined maximum power of 340 HP (250 kW) and a maximum torque of 542 Nm. The power system is matched with the 6-speed wet gearbox of Gertrak.

The ride comfort of P8 is better than that of VV7 at the start, and the dynamic response is much more positive during driving. With the accelerator pedal, the sense of acceleration is still obvious. When the speed exceeds 100km/h, the power will not feel any attenuation. On the high-speed test ring track, with four people on board, P8 can still run 239km/h, while the flagship model, car home actually measured the acceleration of 0-100km/h for 6.25 seconds. In EV mode, lightly stepping on the accelerator pedal can only rely on the motor to drive the vehicle. If you step on the accelerator pedal suddenly, the engine will intervene. When the engine intervenes, the driver can feel it, but the sense of suddenness is not strong.

● Recommended models

There are three models in WEY P8, and the subsidized price is 259,800-279,800 yuan, all of which are in line with our recommended price range. The recommended model is the exclusive model with a price of 269,800 yuan, which belongs to the middle model of WEY P8, and is 10,000 yuan more expensive than the exclusive model. However, it is worthwhile to have additional configurations such as parallel assistance, lane departure warning, lane keeping assistance, fatigue driving reminder, reversing side warning, electric trunk and electric trunk memory.

● Summary:

In appearance, P8 continues the exaggerated design of VV7, and its good comfort is still one of its highlights. At the same time, this car has strong driving power and excellent ride comfort, which is a big selling point. However, the space in the trunk is not ideal, and the space in the back row is also average. If the WEY brand new energy vehicle can change these shortcomings in the future, its market potential will be even greater.

Chang ‘an CS75 PHEV

Subsidized selling price: 165,800-196,800 yuan.

Pure electric cruising range: 60km

● Model introduction

Changan CS75 PHEV is a compact SUV, so the price will be cheaper than the above two models. The car was officially launched in August 2018. The exterior design of the new car is consistent with the fuel version, and the interior materials are good. It is equipped with a battery pack with a capacity of 12.96kWh, which can reach 60km in pure electric mode.

Changan CS75 PHEV is actually a plug-in hybrid version of Changan CS75, so it basically continues the design of fuel version in appearance, but changes in details. The change of the net style is the most obvious way to distinguish it from the hybrid version. The net has changed from the original horizontal stripes to the current similar mesh, and at the same time, the blue decoration has been added inside the net, which not only improves the recognition but also shows its new energy identity. In addition, blue elements have been added to headlights, fog lights and rims. The tail style has not been deliberately changed, but the exhaust is still bilateral, and the taillights are still designed through, which enhances the recognition. At the same time, LED strip is added internally, which further enhances the sense of exquisiteness.

The style of the interior will not give you anything particularly novel in design, nor will it deliberately emphasize its identity as a new energy source in color matching, and the overall look tends to be atmospheric. In addition, the details are handled well, the stitching on the center console is very delicate, and except for the lowest models, the suede packages of other models are handled with a sense of grade.

The flat-bottomed steering wheel is moderate in size and comfortable to hold. The back is equipped with paddles not for shifting gears, but for adjusting the energy recovery intensity. The car is equipped with six gears of energy recovery adjustment. The instrument panel is a 10.25-inch full LCD instrument, which looks very clear, but it is somewhat reflective under strong light.

There are no physical buttons on the air conditioning panel, and the design of touch buttons is adopted, which has a strong sense of science and technology. At the same time, the design of air volume, wind direction and temperature control is similar to that of the lever, which is very convenient to design and use. The style of the shift lever is different from the fuel version, and a new design is adopted. Behind the bar is the mode selection knob, which is equipped with ordinary, snow, sediment and mountain modes for the driver to choose.

The performance in space belongs to the mainstream level of the same level, the sitting is not crowded, the leg space is also good, the rear seats can support multi-angle adjustment, the central position is equipped with headrest, and the floor is very flat. The trunk has a good volume performance, and the interior is quite flat. The seat can support 4/6 ratio, and it is nearly flat after being laid down, which can further expand the loading volume. At the same time, there is a 220V power supply in the trunk, and the discharge power can reach 3kW, which can supply power for induction cookers and refrigerators used for outings.

In terms of power, Changan CS75 PHEV is a power system composed of a 1.5T engine, P1 generator, P3 front axle drive motor and P4 rear axle drive motor, in which the maximum power of the engine is 156 HP (115 kW) and the maximum torque is 225 Nm, the maximum power of P3 front axle motor is 70 kW (95 HP) and the maximum torque is 200 Nm, and the maximum power of P4 rear axle drive motor is 80 kW (109 HP). The maximum torque is 200 Nm, and the "three engines" consisting of front and rear double motors and 1.5T engine can output the maximum power of 255kW (349HP) and the maximum torque of 605Nm in hybrid mode.

In EV mode, the engine of Changan CS75 PHEV will not intervene even if the accelerator pedal is depressed deeply, but the maximum speed of the vehicle will be limited to 130km/h until the battery pack is exhausted. If you are in AUTO mode, the engine will work if you step on the accelerator pedal deeply, but the vibration of the gasoline engine will not be felt by the driver, and the whole process is still very quiet and smooth. In CHARGE mode, the generator will charge the power battery forcibly and charge the battery to a higher level, at which time the engine energy consumption will become higher, but not at an unacceptable level. Energy recovery has 6 gears adjustable and 0 gear closed. At this time, the subjective feeling of releasing the accelerator pedal is not much different from that of a conventional fuel vehicle. In the first 3 gears, the dragging feeling is not obvious, which has little effect on the ride comfort. When the accelerator pedal is set to 4 gears, there will be a slight dragging feeling.

● Recommended models

Changan CS75 PHEV has three models, and the subsidized price is 16.58-196,800 yuan. This time, we recommend the 2018 1.5T PHEV elite model, which is 13,000 yuan higher than the lowest model, but it can get active braking, full-speed adaptive cruise, electric adjustment of the passenger seat, heating/ventilation of the front driver’s seat, boss key and other configurations. Moreover, the model will be wrapped in suede with a sense of feel and grade.

● Summary:

Changan CS75 has performed well in the market since its launch, and the launch of its plug-in hybrid model has enriched its product line. The appearance style looks quite regular, and the changes in details have increased the recognition of the car. At the same time, the workmanship and materials used in the interior are satisfactory. In terms of configuration, Changan CS75 PHEV can also meet the needs of most users. Generally speaking, it is a good product.

Roewe eRX5

Subsidized selling price: 195,900-229,900 yuan.

Pure electric cruising range 60km

● Model introduction

Roewe eRX5 is a plug-in hybrid SUV that entered the new energy market earlier at this level. Among them, two models, the Zunrong flagship and the distinguished flagship, were listed in 2016, but the car added a hybrid exclusive version in 2018. Entry model. There is no difference in the appearance and interior of the three models, but the difference is in the configuration.

In appearance, Roewe eRX5′ s styling design is similar to the RX5 fuel version, but the mesh size is larger, and the chrome-plated hollowing treatment is carried out to enhance the layering of the front face. The headlight style is inspired by Yu Ruyi, and the NETGREEN logo on the front fender can be seen that it is different from the fuel version. There is a charging interface on the rear fender of the co-pilot’s side, which can fully charge the battery. The official charging time is 3 hours, and there is a fuel interface on the rear fender of the driver’s side. The car can be filled with 92 # gasoline. The rear enclosure style at the rear of the car is the best way to distinguish it from the fuel version, and its exhaust pipe also adopts a hidden design.

Compared with the appearance, there are fewer changes in the interior. At first glance, there is no obvious difference, and there is no intention to add some new energy elements. The workmanship and materials are good, and the positions that can often be touched are wrapped in soft materials. The color matching of the 12.3-inch LCD instrument UI design is also quite pleasing. It looks like there is no sense of disobedience, and the displayed functions are quite rich, and the user experience is good. I believe everyone is familiar with the large multimedia screen in the center. The zebra system is still very convenient to use, which may be due to personal habits. I always feel that it is better to set a few physical buttons properly.

In terms of space, the performance of eRX5 is enough for daily use. The experiencer with a height of 178cm has no sense of depression when sitting in the car. The rear row space is quite spacious and there is no pressure in the leg space. At the same time, the support of the seat is quite good. In addition, the rear seat can be adjusted back and forth in a small range, and the headrest is arranged in the center, which can improve the head support of the rear central passenger. The interior of the trunk is relatively flat, which is 537L in the standard state. At the same time, the rear seats can be laid down at a ratio of 4/6, and the volume can be expanded to 1518L after being laid down, but the only regret is that it is not a very flat surface after being laid down.

Roewe eRX5 is equipped with a 1.5T turbocharged engine with a maximum power of 169HP (124kW) and a maximum torque of 250Nm. At the same time, it is equipped with a motor with a maximum power of 56kW (76HP) to provide power for the whole vehicle. The power system of this system can generate a maximum torque of 702Nm. In addition, eRX5 is equipped with an ISG motor which mainly charges the battery with a maximum power of 30kW.

From my colleague Huang Zhengqiao’s previous test drive, we can know that when Roewe eRX5 is driving normally, the response speed of accelerator pedal is similar to that of gasoline version 1.5T model, but slightly slower than that of 2.0T model. However, it is easy for you to get addicted to this smooth and quiet feeling when driving in pure electricity. Even if you step on the accelerator more at low speed, the unique vibration of the gasoline engine will not appear here at all, unless you need to accelerate quickly, you will feel the intervention of the engine slightly. In the Normal mode, the engine intervention requires the opening of the accelerator pedal to reach more than 60%.

● Recommended models

Roewe eRX5 has three models, and the recommended model is Hybrid Connected Premium Ultimate. Although the entry-level hybrid exclusive version was launched this year, the car doesn’t have a series of configurations such as car networking, voice control and navigation, full LCD instrument, etc. Unless your car purchase budget is very limited, otherwise you might as well spend 14,000 yuan more to choose the premium flagship version of hybrid interconnection higher than it. First of all, the car can be equipped with zebra system, which is still good in practical use, and at the same time, you can add full LCD instrument, remote start and other functions.

● Summary:

In the compact plug-in hybrid market, Roewe eRX5′ s good reputation has been recognized by many consumers. Although the eRX5 has been on the market for two years, it is not out of date in terms of appearance and interior. The relatively good driving texture is also its plus item, and this year, an entry-level version with lower configuration was introduced, which enriched the choice space of consumers.

Full text summary:

Today, I brought you four plug-in hybrid SUV models with a price of around 200,000 yuan. Among them, two medium-sized SUVs, Tang DM and WEY P8, can be said to be in the vanguard position of the current medium-sized plug-in hybrid SUV. The new generation of Tang DM is really eye-catching with its new style appearance and completely changed interior, and its good acceleration ability is also a highlight; WEY P8 is very sporty and exaggerated in design. This design once had a good evaluation in VV7, and now it is used in P8.

The compact SUVs Changan CS75 PHEV and Roewe eRX5 brought this time also have their own uniqueness. The good workmanship and interior of Changan CS75 PHEV are still very pleasing, and the good sales and good reputation of its fuel version also laid the foundation for it. Roewe eRX5 entered the market for a period of time, but it is not out of date at present, and its comprehensive strength is also good. How to choose these four models? I believe you have a preliminary idea after reading this article. (Text/Figure car home Liu Liwei)

Cctv news Liu Dianying, 60, lives in Tancheng, Linyi, Shandong Province. He has been working in Qingdao for one year and is usually responsible for cleaning Dandong Road. Liu Dianying’s work is basically from 5 a.m. to 5 p.m., because she needs to keep walking on the road, she often can’t eat on time, and most of the food she eats is cold.

A month ago, Liu Dianying found a refrigerator in front of a restaurant in Dandong Road. The refrigerator was full of dumplings, steamed stuffed buns and other foods. The words "free and appropriate use, no waste" were posted on the door of the refrigerator, and a sign was set up next to the refrigerator, which read: "Love charity station, small charity, great love." "Please heat the food. There is a microwave oven in the store for heating."

Since then, Liu Dianying can get food from the refrigerator and then heat it in the store, and often get hot meals.

The owner of this refrigerator is Liu Zheng, an out-and-out "post-90 s". After joining the army for five years, he returned to Qingdao and opened a restaurant, mainly engaged in breakfast and lunch. Although the store is not big, business is good.

Every day, there will inevitably be some unsold buns and meals left in the store. Liu Zheng feels it is a pity to throw them away. He used to give food to sanitation workers for free, and sometimes to homeless people lying under overpasses, but this is not a long-term solution. When Liu Zheng read an article about "sharing refrigerators", he came up with the idea of putting a refrigerator in front of the hotel.

Today, the refrigerator outside the store has been placed for more than 20 days, and the effect is good, mainly because sanitation workers come to take it. When the "shared refrigerator" was first set up, many people didn’t believe it, but after nearly a month, many people gave Liu Zheng a thumbs up.

While dedicating his love, Liu Zheng also paid special attention to food safety. He wrote the shelf life on the lunch box containing food and gave the sanitation workers free heating. He admits that there is still a long way to go to "share the refrigerator" and avoid becoming a "risk refrigerator".

"In fact, he often helped us before setting up a shared refrigerator!" Liu Dianying said, "Although people’s meals are said to be free, it’s still a little embarrassing to eat all the time! People helped me, and I can’t just be good at others. I can’t help you with other things, but when I walk to his door and see which ones are dirty, I will be rewarded! "

In the cold winter, a refrigerator warms people’s hearts. "I hope that people who can’t eat have a place to eat, and those who can’t eat don’t waste it." Liu Zheng’s way of offering love is more practical and environmentally friendly. It not only avoids the unnecessary waste of food, but also allows people who can’t eat or eat on weekdays to have a hot meal and do what they can to help others from their own reality. We should not only praise Liu Zheng’s love, but also learn from his idea of giving love. Let’s say thank you to Liu Zheng here!
