The passionate years starting from the college entrance examination

Chapter 196, National College Student Mathematical Modeling Competition

Chen Guohua did not expect that Duan Xuefu and Xu Xianyu, two directors of Peking University, would come to Zhenhua Research Institute to look for him.

Although Peking University and Zhenhua Research Institute are both located in Wudaokou, the two units are very close to each other.

However, Zhenhua Research Institute is a confidential unit.

Moreover, Chen Guohua also told Duan Xuefu and Xu Xianyu before that they should keep it secret.

If something happens, you can call directly to inform them, or you can ask Zhang Jichuan and Xue Jinquan to inform them for help.

However, now that the two directors have arrived at the entrance of the institute, Chen Guohua can't just turn them away, can he?

"Director Duan, Professor Xu, please take a seat quickly, come and have tea."

After warmly inviting the two directors to sit down, Chen Guohua quickly picked up the cup and poured them tea.

He doesn't have any secretary here, and he doesn't usually have many guests.

Even if guests come, such as those from the fraternal units of Factory 107, they must be a group of people. At that time, it will be Ge Shouzhi and others who will help entertain them.

Usually when Qiu Zongyue and the others come, they usually just sit down and leave, and it doesn't matter whether they entertain or not.

Therefore, it is really rare to see a wave of customers coming in the morning and afternoon like today.

Duan Xuefu and Xu Xianyu smiled cheerfully, drank a few sips of tea, chatted politely, and then got straight to the point.

"Guohua, how long has it been since you returned to Peking University? Have you forgotten that you are still a professor at Peking University?"

As soon as these words came out, Chen Guohua was immediately embarrassed.

It seems to be true!

In my memory, the last time he went back to Peking University was this morning, um, to send his wife to class.

But he himself has never gone to Peking University to study.

"Well, Director Duan, Lao Xu, and you guys all know that I really don't have much time recently. You see, I was just making progress over there next to the backup power supply room."

Chen Guohua explained:

"Integrated computers have come out. You should have heard about this. But because it has come out, you need to hurry up and program because there is a very urgent project that requires mathematical modeling."

Duan Xuefu and Xu Xianyu were both very curious when they heard the words mathematical modeling.

Just because both of them are engaged in mathematics and computers, Duan Xuefu is engaged in pure mathematical theory research and education, and Xu Xianyu is engaged in computer research and education.

The mathematical modeling mentioned by Chen Guohua is based on computer programming, so both of them are very interested.

After learning the definition and role of mathematical modeling, the two were immediately delighted.

"Professor Chen, when will you offer a course on mathematical modeling in the Department of Mathematics at Peking University? I think our students at Peking University will be very interested."

Duan Xuefu was the first to speak, with a somewhat excited expression.

For the Mathematics Department of Peking University, it is already a huge regret that Chen Guohua did not speak.

But now Chen Guohua has used computers to create a new course. How could Duan Xuefu miss such a good opportunity?

You can't wait until Tsinghua University or other universities know about this and come over to invite Chen Guohua to offer such a course before he, the head of the Mathematics Department of Peking University, speaks out, right?

Isn't this funny!

Xu Xianyu said more simply and neatly:

"Guohua, don't listen to Lao Duan. A course like mathematical modeling can already be opened as a major, and it requires more computer knowledge, especially programming technology, so it has to be placed in computational mathematics. Tie it this way.”

I have to say that Lao Xu's vision is still very sharp.

Mathematical modeling is indeed an advanced professional discipline for Peking University in this era.

But no matter what department it is placed under, it will inevitably require students to understand programming knowledge and mathematics knowledge.

And the requirements for this part of mathematical knowledge will be higher.

You must know that mathematical modeling is to establish a mathematical model based on actual problems, solve the mathematical model, and then solve the actual problem based on the results.

Hearing Xu Xianyu's words, Duan Xuefu glared dissatisfied.

So the two started to quarrel.

"Two professors, please don't argue for now. Let's first listen to what professional knowledge the subject of mathematical modeling requires, okay?"

Chen Guohua interrupted the quarrel between the two without laughing or crying.

When the two heard this, they stopped quickly. Chen Guohua suspected that they were acting.

"What Lao Xu just said makes sense. Mathematical modeling should be a major, not a subject, because it covers knowledge from many disciplines."

"If you want to carry out mathematical modeling, the requirements are still very high. The first is model analysis, graph theory algorithms, numerical analysis algorithms, image processing algorithms, software programming technology, computer application technology, differential equations, etc."

"Just this knowledge does not necessarily guarantee that students can learn this major well."

Looking at the two directors of Peking University, Chen Guohua talked eloquently:

"Therefore, my suggestion is that after June or July next year, I will take out some of the lecture notes and then Peking University will open a new major."

"Alternatively, I will take out the handouts and give them to sophomores and juniors who have a certain foundation in mathematics and computers to study, and our Zhenhua Research Institute will organize a national mathematical modeling competition."

hiss!

After listening to Chen Guohua's words, Duan Xuefu and Xu Xianyu were both dumbfounded.

The previous suggestion is quite normal. After all, to open a professional subject at Peking University, you only need to apply to the education department.

Generally speaking, the education department will not refuse such an application.

But the National Mathematical Modeling Competition is a bit more powerful.

"Professor Chen, if you were to hold a national mathematical modeling competition for college students, you might not have enough computers to allocate it, right?"

As soon as Duan Xuefu finished speaking, Xu Xianyu added:

"That's right, Guohua, you have to know that our country doesn't have much funds right now, and it's impossible to provide so many computers. What's more, the computers here in the capital are very tight, and those universities in other places."

Needless to say, Chen Guohua also knew what happened next.

After all, the place with the most computers in the country now is the capital.

Other cities such as Magic City, Baiyun City, and Jinling have no or few computers at all.

Even in Beijing, even Peking University does not have computers now, let alone other universities?

Chen Guohua chuckled and said:

"It doesn't matter, just because it's not available now, doesn't mean it won't be available next summer."

"I'm going to give you a hint here. I won't go into details about where the computer came from. Anyway, there must be one."

"I thought about it just now and decided to hold the National College Student Mathematical Modeling Contest first. After all, the country definitely needs such compound talents more."

"We will use the entire summer vacation to hold it. The requirement is that sophomores and above will participate. Freshmen will be exempted."

"I hope that Director Duan and Professor Xu can strongly support my mathematical modeling competition. As for whether the mathematical modeling major should be established, we will discuss it later."

Regarding this point, Chen Guohua also thought of the Tinder Plan.

The mathematical modeling major established at Peking University is actually of little use.

Because it won’t be long before this profession will cease to exist.

It's better to use the National College Student Mathematical Modeling Competition to get a good feel for it.

During a summer vacation, all these college students participating in the competition can experience computers and learn programming techniques.

After all, before these college students can participate in the competition, they definitely need to take a basic knowledge test such as differential equations, application awareness, and numerical analysis algorithms.

Not all college students can participate in such mathematical modeling competitions.

Therefore, after the preliminary examination, qualified college students were selected to come to the capital to participate in the competition.

As long as they come to the capital and select the best among the best, then the top ten or even the top twenty college students, Chen Guohua said that he will book these college students.

After all, subjects such as mathematical modeling involve ultra-complex knowledge and are complex talents, so only Zhenhua Research Institute can afford them.

As for other units, forget it.

As long as he enters Zhenhua Research Institute, Chen Guohua will start the Tinder Plan.

Just like Hua Juzuo and his group of fifty-seven college students, they are still conducting secret military training at a base in the suburbs of Beijing.

The confidentiality regulations are part of the Tinder Plan. When the time comes, other parts of the plan will be launched again.

In short, when the coldest month of winter arrives, live your life behind closed doors and don’t go out to participate in activities such as building snowmen, having snowball fights, skiing, etc.

In this way, it will definitely be much safer and you will not get colds or fevers.

After listening to Chen Guohua's words, Duan Xuefu and Xu Xianyu thought for a while, then nodded and agreed.

It is not appropriate to apply for this major rashly now. It is better to go back and make more preparations.

Reports need to be written, materials need to be prepared, and applications have to be made to the superiors. All this is left to Lao Duan and Lao Xu.

Moreover, Chen Guohua has not yet completed the mathematical modeling, so no one is in a hurry.

After skipping the topic of mathematical modeling, Duan Xuefu mentioned the purpose of their visit today.

"That's right, Professor Chen. Some time ago, didn't you ask us to help you identify any suitable students?"

"We all know that your requirements are very high, so we have screened them for you. Now there are several lists. Why don't you take a look?"

After receiving the student information handed over by Duan Xuefu, Chen Guohua lowered his head and looked at it.

The first student was Jiang Boju, who was born in Jincheng in 1937. He graduated from Baiyuncheng Experimental School in 1953 and was admitted to the Department of Mathematics and Mechanics of Peking University.

After graduating in 1957, he stayed at the school to teach. He is currently a lecturer in the Mathematics Department of Peking University.

His current main research is in the fields of fixed point theory and low-dimensional topology in topology.

Chen Guohua frowned a little when he saw this.

Although the other party studies topology, he may not be able to keep up with his mathematical thinking.

The current mathematical geniuses in the Mainland should be Chen Jingrun and Wang Yuan, but they are now assistant researchers at the Institute of Mathematics, Chinese Academy of Sciences, and their status is no longer low.

What's more, Chen Jingrun is a student of Hua Luogeng, and Wang Yuan is a student of Wu Wenjun.

You can't let Chen Guohua snatch these students, right?

There is no need, and Chen Guohua doesn't bother to take the credit.

The name of the second student is Chen Shuxing. He is an authentic native of Modu and was born in the same year as Chen Guohua.

Chen Shuxing was admitted to the Department of Mathematics of Fudan University in 1957, one year earlier than Chen Guohua.

He was admitted to Fudan University and his IQ was definitely among the best among his peers.

Moreover, some time ago, Chen Shuxing also participated in a mathematics competition. The questions were all mathematics questions that Duan Xuefu and Erdesh came up with. They were not simple questions.

In this competition, Chen Shuxing won the championship with the first place in the country.

With such a great talent, of course it attracts much attention.

Chen Guohua did not comment on this.

After all, the other person is about the same age as him and is still in his senior year. Only if he meets him will he know whether he is great or not.

In addition to Jiang Boju and Chen Shuxing, there are also Li Jianshu, Chang Jinping and Bai Ronggen.

There are five students in total, all of whom are college graduates or college students, and they are all around 20 years old.

"How is it? Do you think any student is good?"

Facing Duan Xuefu, who was full of expectations, Chen Guohua still couldn't hold back, shook his head and said:

"These students are all very good, but they are far from what I want. I estimate that if I were really asked to take care of them, I would probably delay them."

Qi Shou Hao spent decades, or even his whole life, just to study one subject, or even just one question.

For example, Papa is the most typical person in the history of time and space.

In order to study the Poincaré conjecture, I conducted scientific research alone and did not communicate with others.

The result was good. Before he died, he gave the mathematical manuscript to his good friend.

It's a pity that his friend only glanced at it and knew that the research direction was wrong, so he spent his whole life following Poincaré's conjecture, which was purely a waste of time.

In this time and space, Poincaré's conjecture has been proven by Chen Guohua. It's time for Papa, a professor at Princeton University, to wake up.

Therefore, Chen Guohua did not want Jiang Boju and Chen Shuxing to follow him and continue to study his mathematical tools.

After all, without a certain amount of talent and perseverance, learning mathematical tools such as nonlinear differential equations and curvature flow is really a headache.

If you can't learn it after several years, isn't it just delaying others?

"No, why don't you give them a chance?"

When Duan Xuefu heard this, he suddenly became anxious and said:

"You must also take care of students, otherwise, we won't have many teachers in the mathematics department."

Upon hearing this, Chen Guohua reacted immediately.

Okay, Lao Duan is targeting Chen Shuxing, right?

Just because the other party is not only a student from Fudan, but also the first place in the competition.

As far as this IQ is concerned, it's definitely not bad.

The most important thing is that by taking away students from Fudan University, it can also strengthen the strength of Peking University.

Duan Xuefu must be very happy for such a good thing.

After thinking about it, Chen Guohua said happily:

"Director Duan, since you like taking care of students so much and you are also an expert in education, how about you accept these students yourself?"

Hearing this, Duan Xuefu shook his head and said:

"That's not possible. I'm so old, how can I take care of other students?"

"Besides, this is a student chosen for you, not for me. What are you doing for me?"

Xu Xianyu next to him couldn't help but interrupt and said:

"Guohua, you'd better stop being picky. It's pretty good to have five carefully selected students now. How about you meet them?"

Forced by the two bosses to choose students, Chen Guohua was helpless.

In this case, he had no choice but to nod first, and then we would meet him and take a look before talking.

"In that case, it's settled, you should be free next week, right?"

"Well, I should be free after Friday."

"How about it's Friday?"

When Chen Guohua heard this, he could only nod.

Duan Xuefu and Xu Xianyu were immediately overjoyed, but Chen Guohua continued:

"It's like this. Didn't I write a few handouts on programming language design before? Last month I wrote a few handouts on system programs. I hope you can take it back, Lao Xu, and print it out for everyone. Take a look."

"Starting next semester, I will arrange for Xue Jinquan and others to give lectures so that students in the Department of Computational Mathematics can also learn how to program."

"Lao Xu, please help me print a few more copies of this handout and give it to the computational mathematics departments of Jinda University, Jida University, Fudan University, and Tsinghua University."

"Next summer's National College Student Mathematical Modeling Competition will depend on them."

Duan Xuefu and Xu Xianyu were stunned when they heard this.

Judging from Chen Guohua's appearance, will he be able to successfully apply for this competition?

Chen Guohua did not give a direct explanation for their doubts.

Anyway, everyone hasn’t seen the actual modeling yet, otherwise, they would definitely be shocked.

As for whether the modeling competition will be held as scheduled, Chen Guohua is not worried about it at all.

For now, it's not a big problem.

Mathematical modeling is not a product of the development of computer technology, but has appeared earlier.

However, the development of computer technology has promoted the rise and widespread application of mathematical modeling.

In the 18th and 19th centuries, many scientists and engineers were already using calculus and other mathematical tools to solve complex physical problems.

This is why, some time ago, when Guo Yonghuai and Deng Jiaxian had a meeting, they would hold Chen Guohua and prevent the latter from leaving.

Just because the latter has strong mathematical abilities, it can help them solve some complex physical problems.

Especially in the fields of bombing physics, nuclear science and other fields, mathematical tools can be used to solve problems in the mushroom egg research process more quickly.

After talking about this, Xu Xianyu remembered that he came to see Chen Guohua today, that is, to urge the latter to implement the integrated computer for the Department of Computational Mathematics of Peking University as soon as possible.

"Old Xu, you'd better ask the school leaders to prepare the money quickly. It should be ready by the beginning of next year."

Chen Guohua smiled, now everyone is anxious to use the computer. But even those military industrial enterprises can only suspend their operations now.

They have to wait until Chen Guohua finishes the math modeling thing before they can get computers. As for Peking University and other universities, there shouldn't be much of a problem early next year.

After all, by that time, the researchers from Zhenhua Research Institute must have completed technical training, and the skilled workers from 107 Military Industrial Enterprises can start production.

Time passed slowly, and when Chen Guohua was about to complete programming, good news came from the Transistor Laboratory.

Five-micron transistors have already been developed.

Chen Guohua, who came after hearing the news, was surrounded by Lin Zhiwu, Zhao Zhixian and Li Chuanzhang as soon as he entered the laboratory.

"Director, look, this is the transistor we just developed. From the current point of view, the yield is only 68%. This can be improved."

"We have also fully tested the transistors, and there are no problems at the technical level. The more troublesome thing now is that it is built into the chip level, which is a bit difficult."

Transistors of a few microns are not just built into the chip.

It is not integrated on the chip using ion implantation equipment or photolithography equipment, so such technical difficulty makes Lin Zhiwu and others have difficulties.

After hearing this, Chen Guohua smiled and said:

"That's even better. You have done a great job, haha!"

"Okay, let's seize the time to improve the yield rate. After a while, I will arrange for our brother units to come over and learn this technology. Hehe, our opportunity to make money has arrived."

Thinking of this, Chen Guohua couldn't help but think of the time when Leader Wu asked him to make suggestions to China Resources.

Fortunately, he hasn't made any suggestions yet. It doesn't matter now. If the price is reduced, the price will be reduced, and there will be a step-by-step price reduction, haha.

Soon, after arranging extra meals for Lin Zhiwu and the others in the cafeteria, Chen Guohua returned to the office without stopping and made a phone call.

After confirming that Qiu Zongyue was in the office, he immediately went out.

Di'anmen Street, this side of the Yamen Office.

After Chen Guohua saw Qiu Zongyue, before he could speak, the latter asked eagerly:

"Guohua, is something wrong? You came to me in such a hurry and didn't say anything."

Seeing the worried look on his face, Chen Guohua did not show off, but said directly:

"Leader, it's like this. Just now, our transistor laboratory has successfully developed a five-micron transistor."

"Didn't Leader Wu ask me to make a suggestion on whether to reduce the price of 50-micron transistors?"

"I have thought of a way now, so I will report my work to you."

Upon hearing this, Qiu Zongyue breathed a sigh of relief.

Fortunately, it was good news, otherwise, he would have been so busy again.

"Let's go then. Let's go see the leader. At this point in time, the leader should have time."

After a while, Chen Guohua met Leader Wu.

So he began to report on his work.

Regarding the price reduction of 50 microns, Chen Guohua’s opinion is this.

That is, the more orders you purchase, the more favorable the price will be.

For example, if you purchase 500,000 50-micron transistors at one time, the price is one hundred dollars each.

If you only purchase 100,000 pieces, the price will be US$250 each.

"Why do you want to price it like this? And if you price it like this, what plan do you think the other party will choose?"

Leader Wu heard this and asked calmly.

After all, according to Chen Guohua's new plan, the price of a large order of 500,000 pieces is one hundred dollars, which seems to be much lower than the previous five hundred dollars, but the requirements have also increased.

At present, at least 100,000 pieces need to be purchased, and the unit price is still US$250 each.

This is almost a one-time deal.

And it may force the other party to be unwilling to purchase.

Or force so many of their companies to join forces for purchasing. Only in this way will they not lose money.

why?

Because for an order of 100,000 pieces, someone else would have to pay $25 million to purchase it.

Although, compared to the previous unit price of five hundred US dollars, it was half cheaper.

But it still hurts a lot.

A list of 500,000 pieces, priced at 100 US dollars each, has a total price of 50 million US dollars.

How many semiconductor companies in the world can make so much money?

Moreover, it is estimated that except for IBM, other companies may not need so many transistors, right?

When Chen Guohua heard this, he chuckled and explained:

"Leader, it's like this. I noticed a lot of newspapers from Wall Street that were submitted by China Resources. One of them reported a piece of news."

"The news said that after the end of this summer, more than 100 computer companies in the United States were successfully registered in a short period of time."

"This news already illustrates a problem, that is, the semiconductor market in North America, or the computer market, has already seen a lot of hot money pouring in."

"Wall Street has identified the two major industries of semiconductors and computers as new money-making outlets."

"Based on this, I can be confident that they will never miss this opportunity."

“The capitalist’s mindset is that problems that can be solved with money are not problems.”

"Furthermore, we cannot let others know that we have developed a five-micron transistor, so the price is so high, which is also based on this consideration."

Hearing this, Qiu Zongyue couldn't help but said:

"Then why did the price of 100-micron transistors drop so sharply before?"

Chen Guohua smiled lightly and said:

"That's because the technology of 100-micron transistors is relatively simple, but the difficulty level of 50-micron transistor technology is very high."

"Right now, whether it's North America, Europe, or Moscow, they haven't been able to come up with 50-micron transistors, which speaks volumes."

"Even if they really break through the technology, it will take at least half a year for them to take it out of the laboratory and mass-produce it in the factory, and the cost issue has not been taken into account."

The labor cost in North America is definitely about twenty times that of the mainland.

The average salary of a researcher at Zhenhua Research Institute is 80 yuan. Taking into account other rewards, it is about 85 to 90 yuan.

For Fairchild Semiconductor, IBM, Texas Instruments and other companies, researchers in their laboratories earn at least seven to eight hundred US dollars in monthly salary.

Even higher.

Even if the average salary is 800 US dollars, converted into RMB, that is 1,968 yuan.

Therefore, the difference in human resource costs between the mainland and North America is twenty-two times.

Although many ordinary workers, waiters, etc. in North America, their salary is actually two to three hundred US dollars, or around three to four hundred US dollars.

However, the salary of laboratory researchers is one or two times higher than that of ordinary people, which is absolutely normal.

Guo Yonghuai and the others had already explained this to Chen Guohua.

Therefore, there are cost issues, time costs and many other factors. Whether it is Fairchild Semiconductor or IBM, they must either unite or have to bear the pain and cut off their flesh and blood.

Other than that, they have no other choice.

As for the computer market being saturated?

No kidding, integrated computers are now available and are being used in national defense, commerce and other fields.

Then the demand for chips from many companies will only get bigger, not smaller.

Not to mention anything else, if IBM gets the transistor, their idea is definitely to break through in chip technology.

That is how to find a way to build more transistors and other components on a chip the size of a fingernail.

Only in this way can the performance of the computer be improved and customers be satisfied.

For example, in the North American Airlines reservation system mentioned earlier, the two large computers used by IBM had a computing speed of only 5 million operations per second.

In terms of performance, it's actually barely enough, but it's definitely still a little behind.

For example, the so-called real-time service, during the upcoming holidays such as Christmas, the airline ticketing system is somewhat insufficient.

After all, in North America, during holidays like Christmas and New Year, not too many people travel.

They were either heading to Miami, to the Caribbean, or to Europe to visit family and vacation.

In North America in the 1960s, many airlines were already present in North and South America, Europe, the Middle East and other places.

Pan American Airways, for example, operates scheduled flights across six continents, with most routes from New York to Europe and South America, and from Miami to the Caribbean.

Pan Am's aircraft alone include DC-8, Boeing 707 and other large aircraft, as well as Boeing 720, Vickers Viscount and other small and medium-sized aircraft, there are hundreds of them.

On October 111, 707, a B aircraft carrying passengers opened a route from New York to London. This flight broke the record for the number of passengers taking scheduled flights at that time.

In addition to these, Pan Am also achieved many world firsts.

Just one Pan Am airline had a huge business.

Not to mention Pan Am’s competitors include TWA, Braniff International, Northwest Airlines and many other airlines.

The demand for large computers for these airlines is also very huge.

Therefore, there are huge market potentials with many potential customers, and there is huge pressure on research costs. They are also worried that after they develop 50 microns, if China Resources makes a big price cut, they will be even worse.

With all these factors combined, will IBM bow its head?

Chen Guohua was very confident about this, so he suggested this.

"By the way, even if they don't bow their heads, is there any loss to us?"

At this time, Leader Wu and Qiu Zongyue were smiling and filled with emotion.

Whether he is engaged in scientific research or operating in these markets, Chen Guohua's vision is very sharp.

It almost took the lifeline of those Western semiconductor competitors, forcing them to bow their heads.

"Since we have nothing to lose, why can't we be bolder about this?"

Chen Guohua continued to talk and said:

"What's more, we also have the big trick of five-micron transistors. Once released, I can guarantee that it will definitely mislead them into other research directions."

"Of course, there is one thing that needs to be noted here, that is, the integrated computer developed by our Zhenhua Research Institute must be guarded and no one can take advantage of it."

The most important component of the integrated computer host is the printed circuit board.

In other words, the most important thing is the chip inside the printed circuit board.

As long as the chip is not stolen, other problems are not big.

After all, there are two thousand transistors built into the chip. Once such technology is known to companies such as IBM, they will not continue to develop five-micron transistors.

After all, all fools know that transistors with dimensions below the micron level are unlikely to be manufactured by existing equipment.

Then they will definitely take out their ion accelerator and other gadgets for development.

There are many laboratories in North America, and they all have ion accelerators, electron linear accelerators, etc.

Although these devices are not currently used in the semiconductor field, it is because they have not thought of this yet, or in other words, they are still thinking about the technical issue of fifty-micron transistors.

According to normal people's logical thinking, if the size continues to shrink after one hundred microns, it will definitely be at the level of fifty microns or one micron.

No one will suddenly want to develop nano-level technology.

Just like Chen Guohua, of course he knows that there are smaller units such as picometers and femtometers below nanometers, so will he skip nanometers and go directly to develop picometers, or even femtometers?

The answer is definitely impossible.

The technology is too difficult and it is not a product of the same era. How can it be done?

The scientific researchers in the laboratory are not fools. They also know that the stars and the moon are things we can pick off just by thinking about them?

However, if someone can produce evidence that someone has been to the moon, then these scientific researchers will definitely find a way to move in this direction.

For example, the first cosmic speed to escape from the earth is Mach 23.2, which is converted to 7.9 kilometers per second.

Scientific researchers will study the distance from the earth to the moon and all the obstacles in this distance one by one, as well as how to develop an aircraft that can fly at Mach 23.2 speed, etc.

They will all work hard to move in this direction.

Today, IBM, Fairchild Semiconductor and other companies, their laboratory researchers are developing transistors at the fifty micron, several micron, or even nanometer level.

Break through these technologies step by step.

However, there is still a way after all, but they may not have thought that there would be technical means such as ion implantation equipment or chemical vapor deposition equipment.

Ten minutes later, Chen Guohua and Qiu Zongyue left the office.

Chen Guohua has convinced Leader Wu, so the follow-up will wait for the arrangements from China Resources Company.

At noon, after returning to Zhenhua Research Institute, Chen Guohua also celebrated with everyone the joy of the breakthrough in five-micron transistor technology.

In the next two days, Lin Zhiwu and others were still working on technical issues to improve the yield rate, but Chen Guohua had already completed programming.

The system program is completed. It is a very crude system, and the built-in programming language is only 0.3 megabytes.

Even so, it is the result of Chen Guohua's compression and re-compression.

If it is simplified any more, it may not be able to function properly.

After it was running, Chen Guohua started to use this computer for mathematical modeling for the first time.

At this time, several people stood behind them. Their mouths were wide open and they were speechless for a long time.

Just because the system that Chen Guohua came up with is so awesome.

Zhang Jichuan, Wan Qingxuan, Yao Shiqiong and others didn't know what to say.

Good guy, there is an arrow on the monitor?

This arrow can still move. Is this the mouse that Chen Guohua mentioned?

But not long after, Chen Guohua started programming mathematical modeling again.

When he got here, he was very fast. After all, he knew the problem of the mushroom egg spherical body that Qin Yuanxun had raised, and he also gave a solution.

Therefore, when he designed it, it was very simple.

However, his operation still shocked Zhang Jichuan and the others.

After Chen Guohua completed the modeling, the model came out quickly after typing on the keyboard.

"Old Chen, is this the mathematical model you are talking about?"

Looking at the beautiful spherical body on the monitor, Yao Shiqiong couldn't bear it anymore.

Zhang Jichuan and the others were also staring at the monitor, their eyes filled with admiration.

"Hey, you haven't left yet?"

Chen Guohua was almost startled, turned around and glared at them, and then said:

"I'm scary. I'll scare you to death. Don't stand behind me next time. Seriously!"

After a pause, he continued:

"Also, have you finished your work? Be the leader behind me and check my work, right?"

Several of them quickly said no, and then quickly changed the subject.

However, Chen Guohua did not tell them about this mathematical modeling, but asked them to go back to work quickly.

As for himself, he picked up the phone and prepared to notify Deng Jiaxian, Guo Yonghuai, and Qin Yuanxun to come over.

Not long after, the first one to arrive was not Deng Jiaxian and others, but Qiu Zongyue.

The arrival of the leader surprised Chen Guohua.

"Hey, your TV can still play such a picture? No, why is this so strange?"

After entering the office, Qiu Zongyue glanced at the computer monitor in front of Chen Guohua, and immediately couldn't move his eyes away.

Before, the computer monitor displayed mathematics, programming languages, etc. that were his most troublesome, and he couldn't understand them.
