The passionate years starting from the college entrance examination

Chapter 308, Nuclear ejection, global earthquake (please subscribe)

In July 1965, it was extremely hot in Beijing.

"Dad, when will you finish your homework? We want to go to the zoo to see giant pandas."

As soon as she entered the room across the small courtyard, Chen Si leaned next to her father and asked in a low voice.

Today is the weekend off, and Chen Guohua is staying at home, preparing to finish the paper he had not finished last night.

Based on what Hua Luogeng and the others said at the meeting a few days ago, Chen Guohua felt that if he wanted to hold a mathematics seminar at Peking University and attract more mathematicians, he should show more 'sincerity'.

In this case, let's get rid of Fermat's Last Theorem.

Therefore, these days, whenever he has time, Chen Guohua will take the time to edit this paper.

Needless to say, Chen Guohua himself has also benefited from the advanced version of the electronic notepad.

However, compared with those electronic dictionaries sold abroad, the electronic notepad he has on hand should be said to be a laptop.

It's somewhere between a real laptop and an electronic organizer, but not a tablet.

The screen size is that of a conventional tablet computer in later generations, which is about ten inches, smaller than a notebook, but larger than an electronic dictionary.

And it's like a notebook, with a keyboard, host, battery, etc.

But its operating system only has an office software called Electronic Notepad, and it doesn’t even have games. What’s left is the computing function.

This thing is only owned by Chen Guohua himself and a few scientific researchers, but not by others.

It will not be mass-produced, it is just an experimental product.

"Sisi, don't disturb your dad. Let your dad work first. When dad is finished working, he will take us out to play."

At the door, Yu Moli walked in with a smile.

Without warning, the little guy ran away. Needless to say, he knew that he was looking for her father.

"Mom, dad, he ignored me." When the little guy saw her mother coming, she immediately flattened her mouth in aggrievedness.

When Chen Guohua heard this, he couldn't help but laugh out loud like a pig, and Yu Moli was also happy.

After Mo Li took the little guy out of the room, Chen Guohua quickly put down the device in his hand.

The work is never done, you still need to live a good life and spend time with your children.

So, he walked out of the room and took the child to the zoo.

In fact, I have been to this zoo many times, just like the Forbidden City, Tiananmen Square, Summer Palace and other places. Chen Guohua and his family have visited countless times.

It can even be said that places such as the Forbidden City and Tiananmen Square are places where the family often walks and wanders.

After spending a pleasant weekend with his children, Chen Guohua devoted himself to work during the working day.

"Lao Yan, help me send this paper to Editor Lu of the Mathematics Journal."

Yan Shouchun was called in, and Chen Guohua handed the paper in hand to him.

"Good director."

After receiving the paper materials, Yan Shouchun turned around and left without saying anything.

He has been to the mathematical journal office several times, so he is naturally familiar with it.

After Lu Qiaoshan received the paper, he was so shocked that he froze on the spot: Fermat's last theorem has been proved?
After Chen Guohua proved the Model conjecture and Taniyama Yutaka conjecture, there was actually not much left.

But as we all know, Fermat's last theorem has troubled mankind for hundreds of years, and even the last point is not so easy to prove.

Previously, after Chen Guohua proved Taniyama Yutaka's conjecture, he also left out a conjecture: If Fermat's last theorem is not true, an elliptic curve can be constructed from Fermat's equation, which cannot be modularly formalized.

This proposition actually assumes that "Fermat's Last Theorem" does not hold, that is, there is a set of non-zero integers A, B, C such that 2\right)">, then the form constructed using this set of numbers is y^2=x( The elliptic curve of x+a^n) times x - B^n cannot be a modular curve.

This proposition is obviously a paradox, because it directly shows that Taniyama Yutaka's conjecture is not true.

But Gu Shanfeng's conjecture has been proven by Chen Guohua himself. Does he want to slap himself in the face?

But in fact, this is the topic specially left by Chen Guohua, and the outside world also calls it Chen's proposition.

In the original history of space and time, this proposition was actually Frey's proposition, which was proposed by Berlin mathematicians in 1984.

Now it was put forward by Chen Guohua in advance, but not long after he put it forward, he proved this proposition again.

The entire proof process is actually to 'queue' the elliptic curve and the modular form through the Galois representation method. It is necessary to match the two 'queuing' sequences correspondingly, but this is a bit difficult.

Therefore, Chen Guohua proposed a new mathematical method to study elliptic curves and the "ring theory properties of certain Heck algebras" in the paper. In this way, the two "queuing" sequences were paired correspondingly, successfully proving this proposition. .

Since then, the combination of Model's conjecture, Taniyama Yutaka's conjecture and Chen's proposition can explain the establishment of Fermat's last theorem.

After Lu Qiaoshan read the proof paper, he went completely crazy.

So cool.

The paper was quickly copied and given to Hua Luogeng and others for review, and this time, they were all numb.

I just finished a meeting some time ago and I said in a vague way that the three papers that Chen Guohua produced before were not influential enough.

As a result, in less than ten days, Chen Guohua proved Fermat's last theorem?

Horror!
After Hua Luogeng and the others reviewed the paper, they asked Lu Qiaoshan to send it out.

Fermat's last theorem is not easy to prove. There will definitely be many mathematicians carefully reviewing and verifying it, because there have been many times in history where the proof was announced but was later found to be wrong.

Such a big oolong will definitely not happen again.

Erdesh, Hua Luogeng and others in the capital, Chen Shengshen, Veblen, Kunihiko Odaira, etc. in North America, William Hodge, Michael Atiyah, etc. in London, Gelfand, Alexandrov, etc. in Moscow, Almost all mathematicians around the world are reading this paper issued by Chen Guohua.

The global mathematics community has fallen into a very strange calm, and it seems that most people are carefully reviewing this paper.

Just because Fermat's last theorem is so important, and it has troubled mankind for hundreds of years, and has been claimed to have been proven before, everyone is very cautious.

Compared with the calmness of the mathematics community, the global media is boiling at this moment.

The New York Times reported the matter immediately, with the title "Secret Calculations, Warriors in the Attic (Fermat's Last Theorem: A mystery that has puzzled the world's wise men for 328 years)".

The Wall Street Journal reported on its front page: Fermat’s Last Theorem Solved!
In the "Washington Post", the incident was reported under the title "Finally cheering 'Eureka!', a long-standing mathematical mystery has been solved!"

The title of The Times is even more hilarious, Fermat’s Last Theorem: A history of a mathematician’s 328-year struggle!
Newspapers all over the world are reporting on this incident, and among them the newspapers on Hong Kong Island are the craziest.

It's like celebrating the New Year.

Ming Pao, Sing Tao Daily, Ta Kung Pao, Hong Kong Commercial Daily and other newspapers, and even many small newspapers no longer reported gossip, but reported the proof of Fermat's Last Theorem.

Because this is a paper proved by Chen Guohua, this is a victory for the East!
"Street boy, why are you running out to play? Why don't you go home and do your homework? In the future, you will be like that Chen Guohua and become a mathematician."

"Look at you, and then look at Chen Guohua? The mainland is poor, but they can prove the useless horse theorem. You have such good food and accommodation, and you can't even pass the middle school entrance exam."

"The Yan family is so rich that you can get a bonus of 100,000 marks for writing a paper? How much is a mark in Hong Kong dollars?"

Everyone on Hong Kong Island knew Chen Guohua's name and the big commotion he made. Some people noticed the 100,000 mark bonus.

In 0.211588, the Bundesbank set the gold content of the mark at 1 grams, and the official exchange rate was 4.20 marks per U.S. dollar.

However, after entering the 1s, the mark has appreciated rapidly, and the current exchange rate is 3.68 marks per US dollar.

Therefore, 100,000 marks is approximately 27,000 US dollars, which is 152,000 Hong Kong dollars.

In Hong Kong Island, where the per capita salary is only 300 to 400 Hong Kong dollars, 152,000 Hong Kong dollars is already a very large sum of money. Many people have to work for many years to earn it.

Chen Yuanchao, who moved out of Kowloon Walled City and came to North Point near Tin Hau Temple, also learned about his uncle.

"My uncle is so awesome. He has never been abroad, but his deeds are being reported all over the world. He is so awesome..."

The Hong Kong Commercial Daily is on King's Road in North Point. He lives near North Point, so naturally it is convenient for work.

Since coming to Hong Kong Island, Chen Yuanchao has become accustomed to reading newspapers every day to learn about outside information.

This is something his uncle Chen Guohua told him, because many business opportunities are actually fleeting.

Newspapers can allow him to understand changes in external information faster, capture the most important information, and make timely response measures.

The plan arranged by Chen Guohua is not foolproof. This time and space are very different from the original time and space.

What's more, Chen Guohua can't do everything in detail.

While Chen Yuanchao was reading the newspaper with a smile on his face, Liu Guanzhong was also reading the newspaper in the central area of ​​Hong Kong Island.

"Director Chen is amazing. He is so busy and still has time and energy to study world-class mathematical problems. He is so powerful."

Of course it is very strong. After all, it is a world-class mathematical problem, and Chen Guohua himself is very busy.

After sighing for a while, staff came outside the door. It turned out to be an order passed from the capital.

That is to be ready to sell new products.

China Resources holds new product launch conferences every March and September, but not all new products can attend this conference.

For example, the new products launched now are just auto parts.

China Resources has been exporting auto parts in the past five or eight years. For example, it was selling the three-point seat belt invented by Chen Guohua.

There are many auto parts, including clutches, transmissions, drive shafts, tires, batteries, etc., and batteries are a new product this time.

As a relatively competitive battery, many different categories have actually been developed within Zhenhua Research Institute.

There are hundreds of battery types used in drones alone, and most of the obsolete batteries, if used in cars, are advanced technologies that overwhelm everything.

At present, several automobile manufacturing plants in the mainland, such as BAIC Manufacturing Plant and FAW Manufacturing Plant, are equipped with relatively advanced automated production lines, using CNC machine tools, highly automated welding equipment, stamping equipment, and injection molding equipment.

For example, welding equipment, one of the basic equipment of automobile parts manufacturing enterprises, can connect parts with high strength, including other welding methods such as shielded welding, manual arc welding, and laser welding.

The reason why there are such highly automated welding equipment is naturally due to the application of computer programs. For example, the most common industrial robot that Tian Jingye, the former head of BAIC, saw in the equipment laboratory of Zhenhua Research Institute, is the most automated application. A basic one.

As for welding, it actually means setting a program in advance and letting the mechanical welding arm make a welding movement in a highly automated production workshop.

The application of these technologies is actually technology research and development completed jointly by multiple laboratories such as equipment laboratories and software laboratories.

It seems very powerful, but in fact, it will be simpler if artificial intelligence programs are applied.

However, today's Chen Guohua has no time to develop artificial intelligence. What's more, artificial intelligence also needs to learn and obtain a lot of data to make faster progress, so it is not that simple.

While Liu Guanzhong was busy making money, a meeting in Beijing had also concluded.

This meeting is to discuss when and where to hold the mathematics report.

The three papers that Chen Guohua produced before were not influential enough.

Now it is enough. It can even be said that Chen Guohua threw a nuclear bomb into the international community and shocked the whole world.

The mathematical topic Fermat's Last Theorem plays a very important role in Europe and the United States.

In 1637, the Gallic scholar Fermat did not write down the proof of this theorem, but his other conjectures made great contributions to mathematics, which aroused the interest of many mathematicians in this conjecture.

Since that time, successive mathematicians have been studying Fermat's Last Theorem. Their related work has enriched the content of number theory, involved many mathematical methods, and promoted the development of number theory.

A problem that has influenced the entire European and American mathematics community for hundreds of years was suddenly proved by Chen Guohua today in 1965.

So the whole world is boiling.

Since foreign media have reported this matter so excitedly, the mainland certainly cannot remain indifferent.

Therefore, not long after the relevant media reports such as the People's Daily, the meeting was held accordingly, and then it was decided to hold a report meeting at Peking University after October 5 this year.

The lecture will invite mathematicians from all over the world to Peking University, and most of the letters will be written by Chen Guohua, Hua Luogeng and others.

Those above are also very supportive of things that can expand our country's influence in the international community.

Even the teacher personally gave instructions to do it beautifully.

With the experience of holding a report meeting at CUHK in Baiyun City before, there will be no problems at all if it is held at Peking University this time.

The news was quickly conveyed through newspapers to mathematics professors in universities and laboratories around the world.

Yang Zhenning, who was far away in North America, couldn't help being surprised after seeing the news reports.

Then he packed his things non-stop and prepared to return to the mainland.

Although he was a scholar engaged in theoretical research in physics, it stands to reason that in the original history of time and space, he returned to the mainland immediately after the 1970s.

In this time and space, Lyndon Johnson had already been to the capital, so Chen Ning Yang should also have been to the mainland.

Actually, it's not that simple.

But no matter what, now Yang Zhenning is also heading to the mainland, and several international students similar to Yang Zhenning have also bought tickets to Hong Kong Island, wanting to go back to the mainland to have a look.

After all, that was the place where they were born, and wandering around all the time was not an option.

Los Angeles, North America, Chinatown, North Leg Martial Arts Gym.

Yu Chengsan is teaching his children to practice martial arts, very strictly and seriously.

"Dad, after I learn how to do it, no one will be able to bully me?"

Thirteen-year-old Li Siyu was sweating profusely, his face was very serious, and his eyes were full of hope as he looked at his father.

Logically speaking, Yu Chengsan's child should be named Yu.

However, at the beginning, Yu Chengsan's daughter-in-law, Ms. Li, was not willing to have contact with him, let alone choose a name related to Yu Chengsan.

Later, Yu Chengsan took the risk to bring mother and son from London to New York, and then they settled down.

Although Watson Jr., the former president of IBM, approached him and asked him to go to Hong Kong Island to carry out the task of assassinating Chen Guohua, he did not complete the task.

Instead, I went out for a walk, and then returned to North America, but instead of going to New York, I came to Los Angeles.

And they also picked up Ms. Li and Li Siyu, mother and son.

In the years since then, things have really settled down. At least in the past few years, there have been no messy things in the world.

However, Yu Chengsan 'retired' from the world, and something happened to his son Li Siyu.

Thirteen-year-old Li Siyu has already gone to school in North America.

As we all know, there must be all kinds of things going on in schools here in North America, and being bullied is completely normal.

Not every child is like Bruce Lee. When he was in school, he took the initiative to beat up foreigners who bullied Chinese people.

So, with Yu Chengsan's guarantee, the father and son secretly learned martial arts without telling Ms. Li.

But Ms. Li still discovered it, and finally Li Siyu convinced his mother, which allowed him to continue practicing martial arts with his father.

"Well, you will definitely not be bullied in the future, but after you become stronger, you cannot bully others, do you understand?"

Hearing his father's words, Li Siyu suddenly smiled happily, and the next exercises he practiced became more powerful.

After practicing martial arts, Yu Chengsan and Li Siyu returned home. Ms. Li, Li Yumin, had already prepared meals.

The family of three sat eating and chatting. It was a very harmonious little family.

Missing Yu and thinking about Yu actually means missing Yu Chengsan, and Yu is actually Yu. This was one of the reasons why Yu Chengsan did not let Li Siyu change his name in the first place, and it also showed that Yu Chengsan was not completely absent from Li Yumin's heart.

After dinner, while Li Yumin went to wash the dishes, Yu Chengsan picked up today's newspaper and read it.

Soon he saw the news about Chen Guohua proving Fermat's last theorem.

Regarding this news, many major newspapers around the world used front-page headlines to report the matter. It was difficult for Yu Chengsan not to pay attention.

"I heard that this professor named Chen is very powerful. Siyu, you must study hard in the future and strive to become a university professor that everyone respects."

At some point, Li Yumin had finished washing the dishes and came out. When she saw the newspaper in Yu Chengsan's hand, she said this.

"Okay mom, I will definitely study hard." Li Siyu said hurriedly.

Yu Chengsan smiled and said nothing.

He is not good at words, but he also knows that it is not good to discourage children. As for encouraging them? It's not easy for him to say something against his will.

Is it so easy to be a university professor?
You still need to be self-aware as a human being.

But if he said this, I'm afraid Li Yumin would be angry.

So just shut up.

However, when his eyes fell on the newspaper again, he was secretly glad that he had not carried out Little Watson's mission.

Otherwise, he might really have no chance of returning.

If Chen Guohua can appear in newspapers around the world, he must be a very powerful scholar.

In 1959, Chen Guohua had already appeared in newspapers.

Although no one has seen Chen Guohua's photo until now, it can be vaguely seen that he is a young man based on the not so fresh black and white photo when he gave a speech in the auditorium of Sun Yat-sen University in Baiyun City.

Yu Chengsan had seen clearer photos of Chen Guohua and had detailed information, so he could recognize at a glance that the Chen Guohua reported in the newspaper was the person whom Watson Jr. asked him to assassinate.

And how could a powerful scholar like Chen Guohua, with Yu Chengsan's understanding of the mainland, have no one to protect him?

What's more, Chen Guohua has never been abroad, and a lot of information can be seen from this.

"Sigh, I don't know if I will ever have the chance to go back to the mainland again in this life."

After reading the newspaper, Yu Chengsan felt happy and couldn't help but have a lot of thoughts.

It is impossible to say that he does not miss the mainland at all.

Even though he was forced to flee from the Northeast, all the way from Siberia to the European island of Great Britain, he never forgot his roots.

Like many Chinese people who traveled to Southeast Asia, South America, and wandered around the world, they all had the idea of ​​"returning to their roots after falling leaves", regardless of whether they had achieved success in a foreign country.

When Yu Chengsan's thoughts were drifting away, he was at the base of the Yanshan Mountains in the capital.

Chen Guohua came here because today is the day when the bomber makes its first flight after completing its test flight test.

After the bomber 'cold' accident happened at the beginning of the year, according to Chen Guohua's suggestion, another new bomber was rebuilt to complete the flight test.

So from March to August now, it took a full five months to complete the flight test.

Compared with test flight testing, first flight testing is the top priority.

Because the test flight test is only on the ground, the first flight test is in the air.

The sky seems to be unobstructed and there are almost no surprises, but birds may appear in the sky, and you may encounter very bad weather conditions, etc.

Especially in extreme weather environments, bombers also need to pass corresponding tests, rather than just being tested in a wind tunnel laboratory.

"Everyone is ready, don't be nervous, just do it as usual."

The person in charge of the base, Xu Dexiang, warned everyone. Chen Guohua looked down at the information in his hands and said nothing.

Soon, the first flight officially began.

"The aircraft inspection is completed. There are no problems with the engine and oxygen equipment. The report is completed!"

"The test pilot has completed the inspection and there are no problems. You can take off!"

"The wind speed is southeast to northwest, light breeze, and the ground temperature is 31.5 degrees. You can take off!"

After the engine started, the bomber taxied on the runway. After entering the take-off runway, it began to accelerate. Then, like 'pulling onions on dry land', the bomber raised its nose and took off quickly.

Unlike fighter test pilots, bomber test pilots are more 'steady'.

The two pilots, Fang Chaozong and Zhang Dun, have been flying this bomber for almost half a year, and they are very, very familiar with it.

They were eager to get their bombers into the air.

So on the day of the first flight test, they let it go and flew vigorously.

Seeing that the plane had already taken to the sky, Chen Guohua withdrew his gaze and stared down at the monitor to check various data.

With radar monitoring and ultra-long-range communication signals, it is certain that the bomber's flight status can be determined at this time.

If communication satellites are launched into space by then, it will be even simpler.

Satellites with different orbital altitudes have different lifespans and launch requirements depending on the altitude.

The orbital altitude of low-Earth orbit satellites is only about 150 kilometers to 200 kilometers. They are closest to the earth and can capture high-resolution images of scenery. They are usually reconnaissance satellites.

However, they are seriously affected by atmospheric drag, so the lifespan of low-Earth orbit satellites is usually only a few months to a year.

The orbital altitude of medium-altitude orbit satellites is 350 kilometers to 1,500 kilometers. They are usually used in earth resource technology satellites, and their lifespan is generally about one to two years.

High-orbit satellites are higher than 2,000 kilometers, and the lifespan of such satellites is more than ten years.

The communication satellite that Chen Guohua and the others want to launch is a high-orbit satellite. Only in this way can the satellite's lifespan be increased to more than ten years.

Of course, Chen Guohua hopes to be able to launch geostationary orbit satellites, but with the current mainland rocket technology and aviation technology, it is really not possible.

Because the geostationary orbit satellite is 35,000 kilometers away from the ground, its movement direction is the same as the direction of the earth's rotation, and its movement period is also equal to the time it takes for the earth to rotate once. It is almost suspended in space and motionless, just like the artificial moon.

The most important are geostationary satellites, which can observe half of the Earth with one satellite.

If three communication satellites are placed in synchronous orbit, global communication can be achieved except for the two poles.

This is the goal that Chen Guohua and others will strive for in the future.

Not to mention anything else, once three geostationary communication satellites are implemented, a few more surveillance satellites are deployed, and an air defense system is established, it will be very difficult for other countries to perform any surgical operations on the mainland. .

Unfortunately, it still takes time to realize these.

In the vast sky, Fang Chaozong and Zhang Dun drove the bomber to an altitude of nearly 20,000 meters to conduct a series of tests.

Higher up in the sky above them, a fighter jet guarded them.

"That plane down there is really big, but it's a pity that it's a little slow."

In the cockpit of the fighter jet, Pan Qianjin complained regretfully, and Guan Xiuyu rolled her eyes:
"Old Pan, are you suffering from hysteria? That is a bomber. It can fly at a cruising speed of Mach 2, and its ultimate speed can reach Mach 2.3. It is already very awesome."

The bomber can reach such speed, which is much better than many fighter jets.

That’s it, what kind of bike do you need?

Pan Qianjin is still not satisfied?
Comparing the speed of bombers with the speed of fighter jets, isn't this stupid bullying of bombers?
"Yes, yes, I have hysteria." Pan Qianjin didn't dare to argue with Guan Xiuyu, and he couldn't win against Guan Xiuyu.

Among the many fighter pilots, Guan Xiuyu is the pilot who admires Chen Guohua and his group of scientific researchers the most.

Because Chen Guohua and others were able to develop the J-65 fighter jet and the H- bomber, allowing pilots such as Gong Jicai, Pan Qianjin, Yin Zhongshou, and Chu Guangliang to protect the airspace of the motherland, which is very awesome.

Before that, Gong Jicai and the others were flying Wanguo brand aircraft, stupid junk fighter jets.

Even the two Jue fighter trainers purchased from Great Britain a few years ago were also killed by the Yaoyao-9 fighter jets.

The speed of Mach 3 is even a supersonic fighter that can reach the ultimate speed of Mach 3.6, while the Viscount fighter is just an ordinary supersonic fighter of about Mach 1.

"Hmph, you know what's going on!"

Guan Xiuyu scolded her and stopped grabbing the other person's pigtails.

At this moment, bursts of laughter came from the ears of the two of them, and Guan Yuntao's serious voice also came out at the right time:

"Comrade Pan Qianjin, Comrade Guan Xiuyu, please pay attention to the impact. You are performing a mission. You must not chat anymore."

Swish!
Pan Qianjin and Guan Xiuyu both blushed immediately. Why didn't they turn off their headsets?
How careless!

The entire southwest command room heard it and was so embarrassed!
If it weren't for being on the fighter jet now, Guan Xiuyu would definitely give Pan Qianjin a kick.

asshole!

Chen Guohua didn't know what happened at high altitude. At this time, his attention was focused on the dashboard.

For the next day, Chen Guohua stayed here at the base. He only left the base after the first phase of the entire first flight test was completed.

After leaving the base, Chen Guohua was called to the Fifth Academy.

When he arrived at the place, Guo Yonghuai and the others were all here, which surprised Chen Guohua: Could it be that there was some technical problem?

Logically speaking, it shouldn’t be!
You know, since he held the meeting on the construction of the air defense system, the scientific research team for this air defense system project has been unprecedented.

Including Zhenhua Research Institute, the Fifth Academy of Sciences, the Chinese Academy of Sciences and other scientific research institutes, as well as multiple military industrial enterprises such as the 985 Factory, the lineup is naturally very powerful.

Qian Xuesen, the former number one scientific researcher in the country, as well as Sun Jiadong, Pan Houren, Yang Jiaqi, Zhao Jiuzhang, Guo Yonghuai, Lu Yuanjiu, He Zehui and others, these scientific researchers are all very powerful scholars.

Not to mention that Chen Guohua, a bastard, personally presided over this project and kept an eye on this project. How could something happen?

"Director Chen, you are back, let's start the meeting."

When Qian Xuesen saw Chen Guohua come in, he immediately spoke.

After hearing the former's words, Chen Guohua sat down and quickly learned the content of today's meeting.

Adjust your research plan!

In the past two days, the materials purchased from overseas have arrived successfully.

The mainland is very big, with vast land and abundant resources, but it cannot support certain materials. The mainland's output is insufficient and there is no way to mass-produce them, so it can only rely on imports.

Especially in this air defense system project, the demand for many metal materials and other related materials has surged.

Currently, according to Qian Xuesen's suggestion, the first low-Earth orbit satellite will be launched in September.

"Now that the solid rocket we are carrying has been prepared, only the satellite is left."

Low-Earth orbit satellites can also launch communication satellites. In the Starlink project of later generations, the satellites are low-Earth orbit satellites with an altitude of 550 kilometers from the earth.

In the time and space of later generations, the lifespan of the satellites created by Max was about five years, which was much longer than the lifespan of low-Earth orbit satellites in the current era.

Chen Guohua can come up with this kind of technology, and even better satellite technology, but the problem is that it is difficult to do so with the current industrial level of the mainland.

Launching rockets and satellites is not as simple as research and development of atomic bombs, let alone building cars.

It requires the cooperation of many high-end manufacturing fields, and it cannot be simply launched.

Artificial satellites are artificial celestial bodies manufactured by humans and sent into space to perform specific tasks. Their related technologies involve many fields, such as payload technology, flight control technology, communication technology, materials science technology, etc.

Taking flight control technology as an example, this should be the best project of Zhenhua Research Institute’s Aero Engine Laboratory.

However, the Zhenhua Research Institute previously studied flight control technology for drones and fighter jets.

The flight control technology needed now is used to control the attitude, position and speed of satellites to meet the needs of satellite missions, including satellite navigation, satellite guidance, attitude control, etc.

"In terms of satellites, what parts are still missing? I remember five days ago, the power system and materials such as solar panels were completed. How far have the flight control systems, communication systems and payloads been completed now?"

After Qian Xuesen finished speaking, Chen Guohua began to understand the situation and took the initiative to follow up on the matter.

He also strongly agrees with launching low-Earth orbit satellites first. No matter what, preliminary tests should be completed first, and then geosynchronous satellites can be launched step by step.

Once the geostationary satellite launch mission is completed, no matter what you want to do at that time, it will be much more convenient.

After hearing his words, the heads of various scientific research institutions spoke one after another and stated the current progress of the mission.

After hearing this, Chen Guohua said decisively:
"Very good, our Zhenhua Research Institute will be responsible for the weather detection equipment and communication equipment. As for the flight control system, it will be left to Dean Qian and your fifth institute. Several scientific research institutes here at the Chinese Academy of Sciences will help. Is there no problem in completing this mission before the launch in September?”

Qian Xuesen nodded solemnly, indicating that there was no problem.

Nowadays, Chen Guohua is a well-deserved leader in both general direction and technical details.

Therefore, Qian Xuesen admired him very much and convinced Chen Guohua to lead everyone to overcome all technical problems.

Therefore, Qian Xuesen would not have any objection at all to this kind of task arrangement.

"Okay, after everyone goes back, be sure to hold fewer meetings and work more on technology. You must achieve 100% overall. If your score is 99 points once, it will be a failure. Please remember this sentence."

After hearing Chen Guohua's words, everyone nodded solemnly to express their understanding.

Chen Guohua's high demands and high standards are not aimed at anyone, but have been the standard set by Zhenhua Research Institute since its establishment.

If someone is found to have any problems at work, they will be called to talk to them immediately.

A score of ninety-nine or ninety-eight is useless.

Because the one or two points lost may cause the rocket launch mission to fail.

This kind of failure is not something that the current scientific research team can bear.

After Chen Guohua established Zhenhua Research Institute, there were only a handful of mistakes.

The biggest mistake was the bomber's 'cold' incident at the beginning of this year.

After the meeting, Chen Guohua stood up and was about to leave. Qian Xuesen had already stopped him and said: "Director Chen, your Zhenhua Research Institute needs to complete equipment such as satellite communication receiving equipment, satellite communication transmitting equipment, communication protocols, data compression and encryption, and other equipment. Are you responsible for the weather detection equipment? "

There is no doubt that Zhenhua Research Institute has many projects.

Therefore, Chen Guohua said that it is indeed a bit worrying that their Zhenhua Research Institute has completed so much equipment.

Guo Yonghuai, Zhao Jiuzhang, Sun Jiadong and others also stood still and cast curious glances.

"Dean Qian, don't worry. Our Zhenhua Research Institute will definitely be able to complete the task. Otherwise, I will not take the initiative to take over the task."

After that, Chen Guohua left the conference room first.

As soon as Chen Guohua came out, Qiu Zongyue stepped forward at the door.

Obviously, the latter has been waiting for a while.

"Leader, why are you standing here? Why didn't you come in and tell us?"

Chen Guohua asked in surprise and concern. Qiu Zongyue shook his head and said:
"Your things are more important. Are you done now?"

Seeing Chen Guohua nod, Qiu Zongyue asked the former to leave with him and return to Di'anmen Street.

Since he was going back to the Yamen, Chen Guohua knew without asking that something big must have happened.

I just don’t know what the big deal is.
