Rebirth of science and technology academic master

Chapter 200 Meeting

The report meeting was already familiar to Qin Yuanqing, and there was no challenge at all.

After all, Qin Yuanqing has held it three times, and once gave a one-hour report at the Mathematicians Conference. Now this report meeting is not big in comparison.

Those who come to the report meeting are mainly scholars in the fields of geometry and algebraic geometry from all over the world. There are nearly a thousand people in total. Some world-class mathematicians will be invited by Shuimu University to give academic lectures, which also makes Shuimu University students A feast for the ears.

The whole report went smoothly. Scholars from all over the world gave Qin Yuanqing applause, which also meant that the minimal model program and the BAB conjecture were officially conquered. The BAB conjecture has officially changed from a conjecture to a BAB theorem. In the future, everyone will definitely mention the BAB theorem. The proposer and the prover Qin Yuanqing will be mentioned.

And in this applause, it also means that the world of geometry has ushered in a new boss. In addition to the number theory boss, Qin Yuanqing also has a geometric algebra boss in the field of mathematics!

Qin Yuanqing's students felt proud in their hearts when they saw Qin Yuanqing talking eloquently on the podium and thousands of scholars sitting below.

And as Qin Yuanqing's students, they also knew that Qin Yuanqing was not only proficient in the fields of number theory and algebraic geometry, but also in other fields. At least, Qin Yuanqing could easily solve the problems they raised during class.

So much so that they all told latecomers on Zhihu or other forums that they must strive to become Qin Yuanqing's graduate students or doctoral students.

You can learn knowledge and don’t have to worry about life!

It’s easy to enjoy the cool weather with the boss at your back. They perfectly interpreted this sentence.

And they all admired Qin Yuanqing's attainments in the field of mathematics. After all, Qin Yuanqing was very busy. He not only had to teach them, but also taught classes for the Automotive Research Institute and the Aeronautical Engine Research Institute. During this time, he basically spent time studying aeroengines. Institute, the results of three papers were quietly published, which shocked the mathematics community.

However, Qin Yuanqing soon stopped paying attention, because he also had to attend a meeting of the superior department. The meeting was of very high standards, and the superior leader directly invited him to attend by name.

Qin Yuanqing took several heads of the institute with him. The meeting was in the conference room of the Science and Technology Committee, with hundreds of people in it.

As soon as Qin Yuanqing arrived in the conference room, he saw many familiar faces, such as aircraft design masters such as Chief Engineer Song and Chief Engineer Yang, as well as aviation engine experts such as Chief Engineer Zhang of Taihang Aircraft Engine and Chief Engineer Yan of Kunlun Aircraft Engine.

In addition to experts, there are also heads of departments.

The leader of the Science and Technology Commission said solemnly: "First of all, I would like to report the good news to you. The high-temperature resistant materials, high-strength steel and other materials developed by Shuimu University Aero Engine Research Institute have completed national acceptance, and all indicators have reached the world's leading level. level."

In the conference room, people who had not yet received the news screamed in surprise. They were all industry insiders, and they knew very well that aero engines are largely restricted by basic materials. According to optimistic estimates, it will take at least ten years to continue to increase. Only with investment in scientific research can we produce domestic aero engines that basically meet the requirements of fourth-generation aircraft.

How come such a big breakthrough was achieved all of a sudden! ?

"Academician Qin, you are the dean of the Aero Engine Research Institute of Shuimu University. Although the aero engine project has been registered, the state has not allocated R\u0026D funds. Your institute has raised funds by itself. Strictly speaking, these technologies belong to your institute! However, the state has not allocated R\u0026D funds. This involves national defense and security, and I hope you can introduce it to everyone!" The leader who presided over the meeting said to Qin Yuanqing.

To be honest, Shuimu University Aero Engine Research Institute is very special among domestic scientific research institutions. It is not a state-owned enterprise or a school-enterprise. It is a new type of cooperative relationship. Qin Yuanqing is very special. He is a pure scientific researcher and has won various honors at a young age. Other scientists are not good at making money, but Qin Yuanqing is an exception. He is simply a master of making money. He uses his own money to conduct scientific research, and then passes it through Technology patents were authorized, but Qin Yuanqing was reluctant to collect money, but Qin Yuanqing donated the money he earned to charity.

Now Qin Yuanqing is leading the Aero Engine Research Institute to make another major breakthrough in this field. Such a big breakthrough can be said to affect all aspects of China's science and technology.

"Everyone, the high-temperature resistant alloy material is mainly nickel-iron alloy, and some parts use single-crystal nickel alloy. The nickel-iron alloy has been verified by sample experiments, and the temperature is stable between 1900°C and 1950°C. The single-crystal nickel alloy reaches the world's leading level. ..." Qin Yuanqing introduced the relevant properties of the material, which aroused everyone's exclamation. They did not expect that the performance was so outstanding: "The formula of the material contains some rare elements. It is recommended that the country controls the export of rare earths!"

Rare earths are mining treasures given to mankind by nature. They are known as "industrial vitamins" and have now become extremely important strategic resources.

Rare earth elements are a collective name for 17 special metal elements. They are widely used in petroleum, chemical industry, metallurgy, textile, ceramics, glass, permanent magnet materials and other fields. With the advancement of science and technology and continuous breakthroughs in application technology, the use of rare earth elements The value will be greater and greater.

Such important resources are treated as treasures in countries such as Europe, the United States and Japan, and they are not even willing to exploit their own resources. China is now the country with the largest rare earth reserves, accounting for about 40%, but other countries also have many rare earth resources. The United States has proven rare earth reserves of 13 million tons, Russia has 19 million tons, and Australia has 5 million tons. But each country's approach is very different.

After 1990, the United States gradually sealed up its mining resources and began to import and hoard rare earths from China. Currently, more than 90% of rare earths are imported from China. Eighty percent of Japan's rare earths come from China. After acquiring a large amount of rare earths, Japan is not in a hurry to use them. Instead, it stores enough resources for 20 years on the seabed. China's strategy is completely opposite, or it has no strategy at all. With less than 40% of its reserves, China has supplied more than 90% of the world's rare earth demand for many years.

"The Middle East has oil, and China has rare earths," this is what the chief designer said. At that time, China had high hopes for rare earths. Rare earths were as valuable as gold and oil. If rare earths were developed well, China would be able to live a Saudi-style life based on resources alone. Rare earths are to China what oil is to the Middle East and iron ore is to Australia. But 20 years have passed, and rare earths have brought a lot of money to China. Obviously, there is only disappointment.

It’s not that other countries cannot mine rare earths, or that the quality of rare earths in other countries is not good, but that China has sold a large amount of rare earths that are “more expensive than oil” at pork prices, squeezing rare earths from the United States, Russia and other countries out of the market. . In most cases, the price of China's oxide, samarium oxide, and cerium oxide is less than 20,000 yuan/ton, which is equivalent to only selling for more than ten yuan per kilogram. It is really cheaper than pork in the same period.

In fact, the prices of China's rare earth products have long been controlled by foreign merchants. Some powerful foreign traders and companies purchase large quantities of China's rare earth products when prices are low, but stop purchasing and using inventory when prices rise. Wait until the price drops again before purchasing, which forces domestic companies in China to compete to sell at lower prices. Foreign countries are all big buyers, while China has more than 100 companies selling to foreign countries. Vicious competition among Chinese export companies has resulted in precious short-term rare earth products such as neodymium, terbium, dysprosium and europium being exported at low prices. However, there is a large backlog of cerium, lanthanum and yttrium, and companies are struggling to make small profits.

In the past, Qin Yuanqing only knew about the importance of rare earths in newspapers and news, but had no real experience. However, now that he has personally seen that a small amount of rare elements are added to nickel-iron alloys and the high-temperature resistance is greatly increased, Qin Yuanqing has a very clear understanding. .

"Many rare elements need to be added to the materials for manufacturing aerospace engines. Rare earths will be very important to our country. This importance is even more important than oil to cars!" Qin Yuanqing said seriously: "Not only aerospace engines, Including aircraft fuselages, submarines, warships, etc., it can be used! It can be expected that with the aero-engine bottleneck gone, fourth-generation fighters can be mass-produced, and related material technologies can also be used in related fields."

"Academician Qin's words are very forward-looking. We will negotiate with relevant departments and issue policies as soon as possible!" A leader said seriously.

"Academician Qin, I heard that your institute is also engaged in aero-engine research. I wonder where the progress is now?" asked an Air Force leader.

"The aero engine developed in our institute is based on the F119 aero engine, which is far behind the Kunlun aero engine and the Taihang aero engine. At present, the corresponding technologies have all completed technical demonstrations. Now that the materials have completed national acceptance, the next step will be to produce aero engines. Prototype!" Qin Yuanqing reported on the institute's aero-engine development progress.

As for confidentiality, the relevant state departments have already settled in the institute after the previous material report was reported. The institute has special police on duty, and no one is allowed to be admitted without identity verification.

The country attaches much more importance to these technologies than the Qin, Yuan and Qing Dynasties!

"Academician Qin, would it be too radical to directly benchmark the F119 aero engine?" Chief Yan asked: "Moreover, the more advanced the aero engine is, the better. It also needs to be combined with the fuselage. The best combination is the two. !”

Qin Yuanqing said: "After solving the aero-engine technology, other problems are not too big. If the relevant units cannot develop and occupy this aero-engine, our research institute will develop a fighter jet based on this aero-engine on its own!"

Qin Yuanqing feels that the aero engine is the core, the heart of a fighter jet. If it is developed but no unit is willing to use it, the worst case scenario is that it will be exchanged for the F22 fighter jet and matched with it!
