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.

　　● At present, the ticketing software is still the choice for many people to buy train tickets during their stay in Spring Festival travel rush. According to incomplete statistics, nearly 60 ticketing softwares currently operating in the market have launched paid ticketing services. Some ticket buyers have reported that when the number of tickets is very sufficient, some third-party software will also check 20 yuan’s acceleration package by default when checking out.

　　● The operating principle of the ticketing software is to use a high bandwidth to frequently refresh the trains that may have surplus tickets, so as to achieve the purpose of giving priority to ticketing once tickets are released. There is an urgent need to standardize the information leakage and hidden charging traps that may exist in the ticketing software.

　　● "Yellow Cattle" will agree to wait until 24 hours before departure by default, and 100% tickets will not be guaranteed. Purchasing with a deposit is more complicated, including the overlord clause such as "the deposit will not be refunded if the ticket is successfully grabbed by yourself". There are even some "black-hearted" scalpers who, after receiving the deposit, snap up tickets directly in other third-party ticketing channels, earn corresponding profits when they grab them, and pull out ticket buyers when they don’t grab them.

　　With the coming of Spring Festival travel rush, the anxious "scalpers" ushered in the last war at the end of the year. From January 10, 2020 to February 18, just a few tens of days, to a great extent, decided their "harvest" in a year. After all, for returnees, train tickets for popular routes are still "hard to find".

　　From the data published by 12306.com, as early as half a month ago, the smoke of this war was faintly smelled.

　　On December 21st, the railway Spring Festival travel rush ticket-grabbing war began to reach its climax: tickets for January 19th, 2020 (the 25th day of the twelfth lunar month) were sold by online and telephone booking, and tickets for January 17th, 2020 (the 23rd day of the twelfth lunar month) were sold at station ticket sales windows, railway ticket sales outlets and self-service ticket vending machines.

　　If the time goes back ten years ago, you were told at the train station that there was no ticket to buy, and at most you would only complain that you came too late. In 2010, with the opening and operation of the 12306 website, the availability of train tickets began to be linked to luck. Until these years, looking at the unusually eye-catching "acceleration package" and VIP in the mobile phone, after waiting for a few days, you began to doubt whether the money spent at the beginning was enough.

　　From "waiting" to "looking forward" and then to "grabbing", Spring Festival travel rush, the largest population migration in the world, has created a huge demand for tickets. People are surprised to find that technological progress has not changed the status quo, but has become the "fat meat" coveted by some lawless people. In this regard, the "Legal Daily" reporter conducted an investigation.

　　Online ticketing is very popular.

　　Ticket grabbing software shows its magic power

　　According to media reports, on December 12th, the railway department began to sell tickets for January 10th, 2020 (the 16th day of the twelfth lunar month), and on that day, the national railways sold a total of 12.561 million tickets. From the first day’s ticket sales, 10.625 million tickets were sold on the railway 12306 network, 0.4 million tickets were sold by telephone booking, and the online ticket sales of the railway 12306 accounted for 84.6% of the total ticket sales. Among the tickets sold on the railway 12306 network, the mobile phone client sold 9.455 million tickets, accounting for 89% of the tickets sold online.

　　At present, the ticketing software is still the choice for many people to buy train tickets during their stay in Spring Festival travel rush. According to incomplete statistics, nearly 60 ticketing softwares currently operating in the market have launched paid ticketing services, or requested to share forwarding links to increase exposure. Some ticket buyers have reported that when the number of tickets is very sufficient, some third-party software will also check 20 yuan’s acceleration package by default when checking out, which is very hidden and will be paid by routine if you don’t pay attention.

　　According to a recent survey of 100 college students conducted by the reporter of Legal Daily, at least 60% of them have used the "acceleration package for grabbing tickets". 50% people think that there is little difference between the acceleration of grabbing tickets and scalper scalping.

　　"The principle of the ticketing software is to constantly send ticket purchase requests, while the 12306 network has to manually send ticket purchase requests, and there is still an interval in time." Wang Zefang, who works in Zhejiang, told the reporter of Legal Daily that his hometown is Bozhou, Anhui Province, and he never spent money to buy an acceleration package in Spring Festival travel rush. "I grabbed it several times without an acceleration package before, but I didn’t get a ticket, so I would change my itinerary or travel by other means of transportation. But overall, tickets to Bozhou are generally more difficult to grab, and hard seat tickets or seatless tickets are not very difficult, so there is no great need to buy acceleration packages. "

　　Wang Hanwei, from Lvliang, Shanxi Province, is currently attending a university in Beijing. He told the reporter of Legal Daily that according to his own experience and that of his classmates around him, if you need to use the ticket rushing package of the ticket rushing software, you can buy it for free. They often take the method of sharing each other’s acceleration packages to grab tickets. "If you don’t use acceleration packages, you will almost never get tickets."

　　"Our classmates have also discussed this issue, and everyone generally thinks that this is a kind of ‘ Prisoner effect ’ Caused. Everyone will accelerate each other and get the acceleration package together, so that everyone has an acceleration package and then they will use this acceleration package. " Wang Hanwei said, but the question is whether the acceleration package has any effect is unknown, so he guessed that if everyone doesn’t use the acceleration package, they may also get tickets. This is the herd effect of the group, or it may be intentional by a third-party platform.

　　In view of the "standby ticket purchase" mode that the 12306 network started to go online last year, "I think it is more reliable, and the standby ticket is made through the official platform, and generally if there is a refund, it will be the first to wait. Therefore, now you will use the 12306 network alternate ticket or ticketing software to grab tickets. " Wang Hanwei said.

　　During the interview, many people in the industry believe that the operating principle of the ticketing software is to use a high bandwidth to frequently refresh the trains that may have surplus tickets, so as to achieve the goal of giving priority to grabbing tickets once tickets are released. Although the same fee is charged, it is essentially different from scalpers hoarding tickets and reselling them at high prices. "Grab the ticket App is not a scalper." However, problems such as information leakage and hidden charging traps that may exist in the ticketing software still need to be standardized.

　　Ticket service charges a fee.

　　It is difficult to guarantee the purchase of scalpers

　　The "Legal Daily" reporter also found a new ticketing service on some social platforms — — Most of the acceleration groups for grabbing tickets are paid groups.

　　The reporter of "Legal Daily" searched in the QQ group with keywords such as "train ticket acceleration" and "train ticket grabbing", which will pop up a lot of information about train ticket grabbing. Immediately after the reporter of Legal Daily entered a QQ group, a user named "A train ticket purchasing" asked "Do you need to buy a train ticket?". The other party claimed that no matter how much the face value of the train ticket is, the purchasing fee is 45 yuan, and the payment will be made only after the order is successful, and no fee will be charged if it is not seized.

　　"A train ticket high-speed rail ticket purchasing" said that the ticketing software he used cost more than 3,000 yuan, and the success rate of ticketing was over 80%. "It is much better than those platforms you use", claiming that there are more than a dozen orders to dozens of orders every day, and 80% can grab it. In the chat content of QQ group, advertisements published by such purchasers are the main ones, and some users help each other to speed up the ticket grabbing.

　　On the morning of December 22nd, after paying 0.5 yuan, the reporter of Legal Daily successfully joined the QQ group named ×× Accelerated Train Ticket Grab Group, which has gathered hundreds of people and its popularity is still growing. In this QQ group, there are more than 20 friend-assisted links from various ticketing software within 5 seconds. According to the group announcement, the level of grabbing tickets at top speed and at the speed of light can be guaranteed within 30 minutes, but the group owner must add WeChat and pay 10 yuan, and the group owner will invite him to enter another WeChat group chat called "Come on".

　　The group announcement of "×× Refueling Group" shows that in this group, some platform bargaining links can also be sent to this group. The group owner said that it is hard to get a ticket in Spring Festival travel rush every year. If you want to reach the level of speed ticket grabbing, you need to buy an acceleration package of 40 yuan/copy, but here you only need 10 yuan to quickly reach the level of speed ticket grabbing, or even higher.

　　The owner told the reporter of Legal Daily that "10 yuan will fill you up with 30 people", that is, it will reach the level of grabbing tickets at top speed, but "there is no guarantee to get tickets, just let you enter this level and see your luck".

　　And this sentence has also become an exemption clause for many "yellow cattle" — — There is no guarantee of 100% ticket issuance. Now, by default, the ticket will wait until 24 hours before departure. Although the standards of each "scalper" are different, everyone’s caliber is similar. First, take the list and whether you can grab the ticket has nothing to do with yourself.

　　The purchasing requirements with deposit are more complicated, including the overlord clause of "the deposit will not be refunded if the ticket is successfully grabbed by yourself". Some netizens reported that there are even some "yellow cattle" with black hearts who, after receiving the deposit and the ticket purchase information, snapped up tickets directly in other third-party ticket purchase channels, earned corresponding profits when they grabbed them, and blacked out ticket buyers when they didn’t grab them.

　　According to the price list given by several scalpers, at present, the ticket purchasing fees in Spring Festival travel rush range from 40 yuan to 150 yuan, which are divided into deposit purchasing and non-deposit purchasing. According to media reports, according to the industry price, the rental price of an independent ticket brushing software ranges from 8,000 yuan to 12,000 yuan per month. If the purchasing price of each ticket is 100 yuan, 120 tickets are needed to cover the cost.

　　Middle-aged and elderly people don’t know how to grab tickets.

　　Buying tickets at the window is practical.

　　For the "main force" migrant workers in Spring Festival travel rush, although the railway department has introduced many measures such as telephone booking, online booking and group booking, it is really not so easy for most migrant workers to book a suitable return ticket because of their educational level and schedule.

　　In the survey, many migrant workers interviewed said that the quickest way to buy tickets online is not easy for them and is rarely used.

　　On December 20th, Beijing began to freeze its hands, but 53-year-old Uncle Li still insisted on buying Spring Festival travel rush train tickets at the ticket window of Beijing West Railway Station. His destination was Henan. When the reporter of Legal Daily saw him, he had just bought a hard seat ticket from Beijing West to Zhengzhou on January 10th next year from the window, and the fare was 93 yuan.

　　When asked why he came to the station window to buy tickets, instead of buying tickets online, Uncle Li said, "There are many trains and kinds of online tickets, which I don’t quite understand. When you come to the window to buy a ticket, you can ask the conductor directly. People will tell you more clearly, and you can get the ticket on the spot, and your heart is much more practical. "

　　On the same day, Uncle Lu, wearing a security uniform, also came to Beijing West Railway Station. He told the "Legal Daily" reporter that he didn’t know much about buying tickets on mobile phones. "I will definitely not increase the price to buy tickets. It is not easy to save money. Why do you add money to buy them?" I have a high degree of time flexibility, and I don’t want any good tickets. There are not many people waiting in line now, and there are quite a lot of tickets, so you can definitely buy them. "

　　From December 20th to 21st, the reporter of Legal Daily didn’t see the "scalper" in the railway station, and the ticket source displayed on the electronic screen was also very sufficient. Generally, the people who come to the railway station to buy tickets are mainly middle-aged and elderly people, and generally express their lack of ability to use the network.
