Rebirth of science and technology academic master

Yes!

During Qin Yuanqing's retreat, time unknowingly passed through the special year of 2020 and entered 2021, arriving on January 8, 2021, the 25th day of the twelfth lunar month!

It just so happens that this day is also the time when all departments of Shuimu, including scientific research institutions, are on Spring Festival holiday. Whether they are researchers, lecturers, or professors, they all have their own Spring Festival holiday!

Qin Yuanqing, who was physically and mentally tired, became more determined to resign as the head of Shuimu. After all, scientific research alone consumed most of his energy, and he even wanted to split himself in half. The position of the head of Shuimu was too important for him. Yan is really a burden.

Now he basically delegates the details to Xu Jiayi and other vice-principals, and they handle it very well. There is no need for him to occupy the pit and not shit!

"Why do you want to resign as the head of Shuimu?" When Qin Yuanqing teased his two children and mentioned his plans to his wife, Jingtian said in confusion.

The head of Shuimu is a very prominent position, both in terms of rank and social influence. I don’t know how many people have struggled all their lives to be the head of Shuimu, but they have never been able to achieve their wish.

As a result, her husband disliked the identity and position of the head of Shuimu as a burden, and wished he could get rid of this burden.

This is nothing!

"After the Spring Festival, my main energy is still on scientific research. I really don't have time to deal with chores. Moreover, Xu Jiayi has also done a good job during this period. It's almost time to push her to the top!" Qin Yuanqing said: "There are major changes unseen in a century. The trend of history is coming. If I don't seize the opportunity, I will regret it for the rest of my life! The mission of the times is hard to shirk!"

Qin Yuanqing cannot tell his family about controllable nuclear fusion technology and anti-gravity technology now, because it is not a good thing for others to know about such a highly confidential project.

Jingtian was also speechless. It was all about nothing, but she had never understood Qin Yuanqing.

WeChat Group's A-share listing was hailed as the world's largest listing financing in history and the largest capital feast in history. The market value exceeded US$1.3 trillion as soon as it was listed, and it hit the daily limit on the day of listing. However, as the largest shareholder of WeChat Group, Qin Yuanqing did not appear at the stock exchange, and did not even send a message. He seemed to disappear silently.

It seems that WeChat Group and Qin Yuanqing have nothing to do with each other!

Even in Jingtian, Qin Yuanqing can only be seen at 12 o'clock every night.

She didn't dare to say anything or ask anything!

"How about we go back to our hometown to celebrate the New Year this year?" Qin Yuanqing looked at his wife.

"Maybe it's too rushed. I have to attend a meeting on New Year's Eve." Jingtian hesitated for a moment, shook his head and said.

Now she is also the head of a large group, and she is also very important in the industry. There are many meetings that need to be attended throughout the year. Some meetings can be attended by other people, and some meetings have to be held in person.

And this meeting is unavoidable!

During the crisis, the entertainment industry and the hotel and real estate industry are also in crisis. Many companies are struggling to support themselves. If this dilemma can be reversed, this will be a theme of this meeting.

Even Qingtian Group has also encountered great difficulties. Dozens of film and television dramas have been postponed for more than half a year or a year. In addition, although the cinema is relatively bleak, it has not been able to open for more than half a year. Everyone's income has been greatly reduced. When watching movies There will be one more consideration in terms of aspects, making the box office for the whole year less than one-third of the total box office in 2019.

Not to mention, the hotel's revenue has also dropped significantly, causing Qingtian Group to suffer huge losses. If Qingtian Group had not had bank loans on its books, it might have faced a bankruptcy crisis.

Qin Yuanqing was a little disappointed, but he didn't force it. After all, people can't help themselves in the world. Since they choose this profession, they will sacrifice a lot.

The entire Spring Festival is better than last year, but overall it is still a lot worse. The bustle of the previous Spring Festival has not been completely restored. Everyone has also reduced visits to relatives and friends, minimized going out, and then peacefully and peacefully became a melon-eater. .

Qin Yuanqing also took advantage of the Spring Festival to cultivate his mind and character, and did not start working until the eighth day of the Lunar New Year. However, the work was mainly concentrated on the heads of various departments. As for other faculty and staff, they would go to work after the fifteenth, sixteenth and tenth of the first lunar month. I won't officially go to work until seven.

However, Qin Yuanqing did not have that good fortune. On the tenth day of the Lunar New Year, Qin Yuanqing attended a joint meeting. The theme of the meeting was about controllable nuclear fusion technology. Qin Yuanqing submitted the project proposal for controllable nuclear fusion technology to his superiors, and some It's been a while.

Participating in this meeting involved heads of almost all departments, as well as nuclear technology experts in nuclear fusion, nuclear power plants and other fields. As the world's first echelon in the field of nuclear technology, China has already established a complete team in nuclear technology. , even fourth-generation nuclear power plants are at the world's leading level.

"Everyone, you must have read the "Project Proposal on Controllable Nuclear Fusion Technology" written by Academician Qin himself. This meeting is to discuss whether this project proposal is feasible, reasonable, and advanced." The host of the meeting said solemnly.

An expert in the nuclear field coughed to attract everyone's attention, and then said: "The prospects for controllable nuclear fusion are undoubtedly broad. No matter who asks me this question, I will answer him this way. But you must know , the ITER project is not optimistic until now. The annual budget exceeds the target by billions of dollars. However, the results are not satisfactory. Governments including the United States have gradually lost patience. Even the United States in order to provide Spiral Stone 7- X has freed up funds and has shut down the WEGA experimental group."

"Controllable nuclear fusion is a systematic project, whether it is inertial confinement or magnetic confinement, or tokamak and stellarator. Only when a series of questions are answered can it be possible to finally solve this problem. But now, None of the problems we face have been fundamentally solved," the expert said slowly.

Everyone else's expressions changed, and then they looked at Qin Yuanqing at the front, because although this expert was only 50 years old, he was a famous nuclear technology expert in China. He participated in the conquering and construction of fourth-generation nuclear power plant technology, which is controllable. His name is also on the list of people who worked on the latest achievements in nuclear fusion.

In terms of his say in controllable nuclear fusion, he ranks among the top ten in the country!

Qin Yuanqing looked at the expert with interest, and then asked with a smile: "Professor Ma, what problems do you think need to be solved?"

This nuclear technology expert was very vocal when he was elected as an additional academician. Unfortunately, he lost the election by three votes. However, it is undeniable that he belongs to China Nuclear Physics and has a lot of say in controllable nuclear fusion.

Professor Ma thought for a moment and then said: "From an engineering perspective, we need a larger electromagnetic field to complete the magnetic confinement of the plasma. However, this is not easy to solve. A large magnetic field means a large current, and When electric current passes through a conductor, it releases heat. We must soak the wire in liquid helium to reach the superconducting temperature and prevent the heating effect of the current from causing the wire to heat up."

"Just having a magnetic field is not enough, we have to find ways to control the magnetic field... Whether it is the current stellarator device or the Tokmak device, there are obvious advantages and disadvantages. Currently, there is no device that can Control the magnetic field." Professor Ma said: "Of course, after talking about so many issues, in the final analysis we have to return to the material."

"If there is a material that can achieve superconductivity at normal temperatures, or at least under less extreme conditions, we can create larger artificial electromagnetic fields to confine plasma, and many problems will become fundamental. It’s not a problem.” After Professor Ma said this, he shook his head, obviously not optimistic about this.

"If the tokamak device and the stellarator device don't work, then we can develop a new device to achieve it. Why should we be restricted in our thinking and insist on fighting these two devices to the end!?" Qin Yuanqing said with a smile.

Tokamak devices and stellarator devices are both containers that use magnetic confinement to achieve controlled nuclear fusion in current international controlled nuclear fusion research.

Tokamak device is a ring-shaped vessel that uses magnetic confinement to achieve controlled magnetic confinement to achieve controlled nuclear fusion. It was originally invented by Azimovich and others at the Kurchatov Institute in the 1950s. In the center of the tokamak is a ring-shaped vacuum chamber with coils wrapped around the outside. When electricity is applied, a huge spiral magnetic field is generated inside the tokamak, which heats the plasma in it to a very high temperature to achieve nuclear fusion. the goal of.

It was precisely because of the development of the Catomak device that at the Third International Conference on Plasma Physics and Controlled Nuclear Fusion Research held in Novosibirsk in 1968, Azimovich announced that he had achieved the goal on the T-3 Tokamak. The electron temperature is 1 keV, the proton temperature is 0.5 keV, and nτ=10 to the 18th power m-3.s. This is a major breakthrough in controlled nuclear fusion research, and it has also set off a wave of Tokamak craze in the world. Countries have successively built or renovated a number of large-scale tokamak devices.

For example, the ST Tokamak, a large-scale stellarator-C converted from Stellarator-C in the United States, the Olmark of the Oak Ridge National Laboratory; the TFR Tokamak of the French Von Knei-O-Rhodes Institute; the Clio of the British Calam Laboratory ( Cleo); Pulsator Tokamak at the Deutsche Max Planck Institute.

It is Huaxia. On September 28, 2006, the new generation thermonuclear fusion device EAST, which was designed and built independently at a cost of 8 years and 200 million yuan, successfully completed the discharge experiment for the first time, obtaining a current of 200 kA and a time close to The core of the 3-second high-temperature plasma discharge actually belongs to the tokamak device.

It can be said that the tokamak device has made a huge contribution to international controllable nuclear fusion research. Many scientists believe that the tokamak device is the key to people's control of nuclear fusion and the key to a new world.
