The passionate years starting from the college entrance examination

Chapter 257, Mathematics manuscripts and two major mathematical theories (asking for monthly votes)

September 30, 1962, the eve of National Day.

Before the National Day came, Chen Guohua still notified 985 Factory and other fraternal units to bring out the hard drive technology, hoping that they could produce it as soon as possible.

"Five hundred hard drives?"

Director Zhu Dayu of Factory 5341 opened his eyes wide when he heard Chen Guohua's demand for hard drives.

After having been in contact with Zhenhua Research Institute for a long time, Zhu Dayu is no longer a computer novice.

The hard disk technology in front of us is definitely the storage technology with the largest capacity of computer memory at present.

One terabyte. Just thinking about it makes Zhu Dayu's scalp numb.

But Chen Guohua said that their Zhenhua Research Institute needs five hundred 1TB hard drives.

Horror!

Cheng Bohong, Yang Liqing and others beside them also looked curious and surprised.

Therefore, the weight of the drone body cannot be too exaggerated.

For example, for the carbon dioxide laser that will be used in the future, the development of the laser itself is not difficult. What is more difficult is the process of obtaining the light source and the photolithography process of the extreme ultraviolet lithography machine itself. The technical requirements in these aspects are too high.

But Chen Guohua only needs to ensure that the team members who develop the lidar system can understand it and that they have understood it thoroughly.

"You also know that our Zhenhua Research Institute has a monitoring room, which consumes a lot of hard drives and is currently one of the biggest gold-eating beasts in our Zhenhua Research Institute."

After Zhu Dayu, Yang Liqing, Cheng Bohong and others left, Chen Guohua went to the aerospace engine laboratory again.

As he spoke, Chen Guohua picked up the paper and pen beside him and began to draw technical drawings and explain the technical points to everyone.

As a result, except for Dai Xizhang, everyone else seemed to know little about it.

Lidar is a radar system that emits a laser beam to detect the position, speed and other characteristics of a target.

Because lithography machines have a huge demand for lasers.

The first method is actually to emit laser light to illuminate an object. Physical processes such as reflection or scattering occur on the surface of the object. The feedback beam passes through the B lens group to cause the feedback light to act on the photosensitive element.

"Okay, we have finished talking about the triangulation method. Next, let's start talking about the time of flight method."

Of course, Shi Jiayi and other researchers from other project teams had to watch, and Chen Guohua did not talk about them.

You know, in the actual application of large drones, the load capacity is very, very important.

Before anyone could answer, Chen Guohua had already said:

One is the triangulation ranging method, the second is the time-of-flight method, and the third is the frequency modulation continuous wave method.

They couldn't refuse tasks related to security.

Time flies, and Chen Guohua quickly finished explaining the triangulation method.

Regarding the research and development of laser technology, Chen Guohua had already developed many lasers when developing lithography machines.

Then lightweight and miniaturized design are essential.

This time, he took the initiative to come here.

However, Qiu Zongyue couldn't help but have a headache after learning about Chen Guohua's purchase volume.

Although they are not professionals engaged in lidar research, large drones are a project as a whole, so it doesn't hurt to listen.

When Dai Xizhang saw him, he was immediately overjoyed and hurriedly pulled him over and asked Chen Guohua to give him technical guidance.

Chen Guohua nodded and continued:

"We all know that the working principle of lidar is actually not fundamentally different from microwave radar."

The payload system includes cameras, lidar, sensors and other accessories, which are mainly used for the tasks undertaken by the universal drone, such as shooting aerial images, collecting geographical information, etc.

"Yes, Director Zhu, you heard it right, that is five hundred hard drives. And this is the demand in the last six months. More will definitely be needed in the future."

Hearing what Chen Guohua said, Zhu Dayu and the others were speechless.

The issue Dai Xizhang is talking about now is the lidar in the payload system accessories.

"The ranging problem you just mentioned, in fact, you should know the entire technical principle. What you need is how to measure the number of threads more accurately, and how to ensure the accuracy of ranging."

"Director Chen, come here and tell us about this lidar technology."

Therefore, pulse lasers are easy to solve, but they also need to be designed to be lightweight and miniaturized.

Chen Guohua stood in front of the table and chatted with everyone. In fact, it was no different from class.

Large UAVs have six major accessory systems, including avionics systems, remote control systems, communication systems, payload systems, chassis systems and others.

Everyone is increasingly confused about Chen Guohua's actions.

"The time-of-flight method considers the time it takes for the beam to return to the receiver after hitting the object to be measured, and uses the basic formula of distance = speed * time, that is, the distance to the object D = c * t/2, where c is the speed of light and t is the laser emission All received time.”

The working principle of ranging is actually very simple, nothing more than three points.

"Do you still remember the basic working principle of the time-of-flight method?"

However, since Chen Guohua is about to complete this year's task quota, let him do it on his own.

Meng Dehai, An Wenchuan, Liu Jinnian and others, as well as Shi Jiayi and Shen Zhiyang, also looked over.

Other parts include pneumatic housing, photoelectric system, etc.

"I mentioned in the technical information before that because the signal-to-noise ratio of using continuous laser as a signal is too low, we always use pulsed laser as the transmitter, and the pulse width used is narrow and reaches the ns level."

Can't just a load system accessory take up a lot of space and a large proportion of the weight?

Similar to the experience in Moscow, where they had to choose between tubes and transistors before, Chen Guohua would definitely not make such a mistake.

Therefore, in his technological research and development in these aspects, he always follows the technical route of lightweight and miniaturization.

The thing he said most often to Qiu Zongyue and others was that he stood on the shoulders of giants.

There is no doubt that he has the skills in these areas and is a time traveler himself, so he knows the future trends very well.

Just like a few days ago, Qiu Zongyue argued with him about the sales time of the home version of the game console.

Although Chen Guohua does not know much about the future trends of this time and space.

But it is obvious that he is very confident in the technology of the home version of the game console. Its early release will inevitably have an impact on the game arcade market.

There is no need to doubt this at all.

Therefore, at the beginning of this year, Chen Guohua directly proposed castrated versions of computers, pagers, radios, digital SLR cameras and other products.

Even later, projects such as game arcades and home version game consoles were launched one after another.

But as of now, it is already the end of September, and the only products launched on the market this year are Huaxin radios, "Ping Pong" game arcade machines, and proximity lithography machines.

"Since we choose the speed of light as the 'ruler' of measurement, accurate calculation of time is very important."

Chen Guohua continued to write and draw on the paper, and kept saying:

“In terms of time calculation, there are mainly several methods such as analog method and digital method.”

Shi Jiayi and the others listened very carefully. Those who didn't know it thought they were also researchers in the lidar project team.

The current aerospace engine laboratory has a very large number of researchers.

However, just the large-scale drone project has been subdivided into dozens of small projects, and more than 300 researchers, after being assigned to these small projects, seem to be very few.

"Let's talk about the simulation method first. The capacitor starts charging from the start signal. After receiving the end signal, the flight time is determined by matching the discharge process with the timing signal. The accuracy can reach ps level, but!"

After a pause, Chen Guohua said in a slightly more serious tone:

"But the change process is nonlinear, the measurement range increases and the accuracy decreases."

This is the technical difficulty.

To figure out the technology of these gadgets and then develop them, a lot of hair would have to be lost.

Fortunately, the researchers at Zhenhua Research Institute are all college students in their twenties, so they are still very young.

However, the age of the researchers at the Ninth Institute, the Fifth Institute, and Liming Engine Manufacturing Factory is very different.

For example, Dai Xizhang is almost fifty years old, which is still considered young.

"Now let's talk about the digital method. When the signal is sent, the high-frequency timing clock is matched. After the signal is received, the timing clock is synchronized to determine the final flight time."

"This method has higher requirements for synchronized clocks, which will affect the time accuracy of the measurement."

After listening to Chen Guohua's technical analysis, everyone, including Dai Xizhang, suddenly realized.

At the same time, I have great admiration for Chen Guohua.

"Director Chen, your knowledge reserve is greater than that of our Dean Qian."

Xie Dingyi from the Fifth Academy said with emotion.

"Director Xie, you have given me the award, how can I compare with Dean Qian?"

Chen Guohua quickly became humble.

The Dean Qian the other party mentioned was naturally Qian Xuesen, the Dean of the Fifth Academy.

Qian Xuesen's knowledge reserve is absolutely huge.

He studied under von Kármán, and his abilities are also very powerful. Otherwise, he would not be said by those in North America that one person can equal five Marine divisions.

Of course, Chen Guohua was definitely being self-effacing, and Xie Dingyi and the others just smiled.

Everyone has a weighing scale in their minds. Who is more powerful, Qian Xuesen or Chen Guohua? There is no meaning in comparing this.

Both of them have shown their talents in the projects they are responsible for and contributed to the country.

The two are stronger and better for the country.

Dang Dang Dang!

Soon, the Zhenhua Research Institute’s closing bell rang.

This ringtone is very much like a school bell.

In fact, there is no need for units like Zhenhua Research Institute to set up such ringtones.

But there is no way. When researchers are busy, they really don’t know when they will get off work.

When he was at the BAIC manufacturing plant, Chen Guohua knew that many workers liked fishing.

In Zhenhua Research Institute, there are no researchers who can fish.

On the contrary, there are often people who have not left their jobs for an hour even half an hour after their off-duty time, but are still struggling on the front line.

So this ringtone becomes very necessary.

Even so, security department staff such as Ma Mingwei and Yin Menglun are still needed to remind them.

"Okay, get off work!"

After Chen Guohua heard the bell, he stopped working, put down his pen, turned around and went out.

Anyway, the technical difficulties have just been explained. If they haven't understood it yet, then they are really not suitable to stay in the laboratory.

Besides, the work is never finished, and we cannot stay in the laboratory and 'work hard' all the time.

Cuihua Hutong, Chen’s house.

"Tomorrow is National Day, where are we going to play?"

After get off work today, Chen Guohua saw his seventh sister as soon as he got home.

Every time Lao Qi comes, he just wants to take advantage of the vacation time to go out and play together as a family.

As for why she didn't wait for Gui Zhiting to come back, maybe she had already informed her in advance, right?

Gui Zhiting has never acted like a 'brother-in-law' at Zhenhua Research Institute, and he is even the same as before.

Except for Chen Guohua, Gui Zhiting and Qiu Zongyue, no one else knew that Gui Zhiting was Chen Guohua's brother-in-law.

It's not that Chen Guohua deliberately concealed it, but that there was nothing to say about this matter.

"I also need to go."

As soon as the child Chen Wei heard that he was going out to play, he immediately started mumbling.

Very loud.

Even the child Chen Si also made babbling sounds, clapped his little hands, and occasionally uttered words like "play".

The pronunciation is not very accurate, but we can also know that the little guy definitely wants to go out and play with it.

No lively event can be complete without the little one.

As a little kid, I love to join in the fun.

"Yes, yes, Weiwei, where are you going to play?" Chen Lihua hugged Chen Wei and asked with a smile.

This is just teasing other children.

Yun Wanshang immediately laughed and cursed:

"I said Lao Qi, you have been married for so long, shouldn't you consider having a child? You know how to tease Weiwei all the time."

Hu Pinggu also echoed, saying that we should really consider having children.

Chen Lihua married Gui Zhiting in December last year. It was a wedding ceremony.

Although Gui Zhiting's grandmother still left later, the marriage was already a fact.

Now that we are all married, isn't it normal to have children?

"Oh, mother, sister-in-law, I understand, you guys don't need to rush us, we're almost done."

The topic has reached the point of provocation, so Chen Lihua wants to avoid it, but it’s difficult!

Facing the urging of several elders, and the sixth sister Chen Guiying who came with her, Chen Lihua couldn't resist it anymore.

So she quickly changed the subject and continued talking about where to go.

Chen Guohua has been holding the child Chen Si, listening to everyone chatting with a smile and teasing the child.

The little kid has grown up a lot, and early childhood education has begun.

Every time I came home, I would either teach Chen Si or Chen Wei.

Fortunately, he only has two children and can still take care of them.

It would be difficult if there were more children.

Yu Moli doesn't have much time to take care of the children recently. Even if he goes home, he is still very busy.

Traditional Chinese medicine and traditional Chinese medicine seem to be the same thing, but in fact, it involves a wide range of knowledge.

For example, the art of taking pulse was enough for Yu Moli to learn for several years.

The family discussed it for a long time and finally decided to go climb the Great Wall tomorrow and take photos of the children.

The day after tomorrow, I’ll go to the Forbidden City for a walk.

National Day is a two-day holiday, which is fixed every year.

However, since 1959, there has been no military parade in the capital.

Without this program, the holidays would still be complete.

So you will still go and play when you should.

Climbing the Great Wall is good for the body, but it is not so friendly to people who have not exercised for a long time.

Lao Chen's body is in good shape. Although he has been sitting in an office these years, he often moves his body.

Yun Wanshang is a little behind. After all, she is used to sitting for long periods of time and needs to write frequently.

As for Chen Guohua and the others, they are all young people. It would be easy for them to climb the Great Wall.

It’s not like climbing Mount Tai, climbing the Great Wall is relatively simple.

After a while, the family packed their cameras, food, water and other supplies, got in the car and headed straight to the Great Wall in the suburbs.

For safety reasons, I definitely did not take the bus, but asked Zhenhua Research Institute to arrange vehicles.

Interestingly, when they arrived at the Great Wall, Chen Guohua and the others actually met Zhang Guangxian, an old enemy.

People whom I haven't seen for a long time turned around and left after seeing Chen Guohua and Yu Moli.

Neither Chen Guohua nor Yu Moli paid much attention to this person.

People and things are in the past. Even if the other party's father is still the prefect, so what?

Climbing the Great Wall officially began, and Chen Si could only be held by Chen Guohua.

As for the child Chen Wei, at first, he wanted to crawl by himself and ran very fast with his short legs.

But within three minutes, I was out of breath.

The adults teased him and asked him to continue crawling.

The little guy was also stubborn and insisted on climbing for several hundred meters before he sat down and stopped climbing.

No matter how much Chen Guohua and the others tease him, he won't crawl.

Although Chen Wei is still young, only over two years old, he is not stupid.

On the contrary, he is smarter and has used more provoking techniques. Even if he wants to continue to force himself, his body cannot bear it.

Therefore, Chen Guohua handed Chen Si to Yu Moli, and he picked up the child Chen Wei himself.

After climbing to a place with relatively few people, I started taking pictures.

In this process, it is inevitable to educate the children, teach them what the Great Wall is, and the story of Meng Jiangnu crying at the Great Wall.

Although these stories are still too far for the little ones, children can remember them if they are told enough.

For example, the child Chen Wei keeps calling Meng Jiangnu's name repeatedly.

This is learning.

At noon, we ate some steamed buns brought from home on the Great Wall. In October in Beijing, the weather was slightly cool, and the autumn tiger had just left.

So the steamed buns brought here will not be very cold.

In addition to steamed buns, there are also pickles and even fried eggs in the morning.

To be honest, having eggs to eat at home is already a very, very good thing. After lunch, we walked around again, took photos, and then started going down the mountain.

Long Kanghou, Yan Shouchun, Ma Mingwei and Yin Menglun were following him. They also wanted to help Chen Guohua give Chen Wei a hug.

But I found that Chen Guohua also had a lot of strength and strong endurance.

The main reason is that Chen Guohua has been exercising before, and every time he goes home for vacation, he often holds his child in his arms for an hour or two, so he has already exercised.

You know, these are two children, taking turns, so the time naturally takes a lot longer.

Chen Xiaoyue and her three little ones, plus Chen Yuanchao, a half-year-old boy, the four of them were constantly complaining that they were tired.

Then he was reprimanded by Chen Gonglu.

Yun Wanshang was also tired, but she was very good at using time to rest and saving her energy, so she could barely hold on.

On the contrary, children like Chen Xiaomin and others, every time they come out, they have wasted a lot of energy before setting off, and they don't know how to recharge their batteries.

So after arriving at the place, if you have fun, run around and jump a few times, your strength will naturally be used up quickly.

Afterwards, the family went to the Forbidden City again, and then stayed at home to rest.

The two days of vacation passed in the blink of an eye.

Time soon entered late October, and the weather in Beijing slowly turned colder.

The temperature is dropping day by day, but foreign exchange income has been increasing.

Entering the end of October, the sales of the "Ping Pong" game arcade are still mediocre.

The monthly output is 50,000 units, all of which are sold out.

As for how second-tier dealers like Raymond and Felix sold these game arcade machines, Chen Guohua didn't care much.

The game arcade project was established in April and sales began in July. So far, China Resources has sold 180,000 units of the equipment.

Another 50,000 devices were sold in October, and revenue increased again by $1.7 billion.

Taking into account Huaxin radios, Huayue calculators, diapers and other products, the revenue has exceeded 200 million.

At the end of September, revenue had reached US$2.69 billion.

Therefore, by the end of October, China Resources' revenue had reached US$2.89 billion.

Haha, there is still 100 million US dollars in revenue, and by mid-November, we will almost be able to break through.

Now let’s see how many billions of dollars this year’s mission indicators can exceed.

November has arrived as expected, and the weather in the capital has become even colder.

The cold air from Siberia blew over, and Zhenhua Research Institute immediately arranged heating.

Without heating, you won’t be able to concentrate on your work.

This morning, Chen Guohua was invited to Peking University.

Erdesh said that he had completed the proof process of the third minor issue of the Riemann Hypothesis and hoped that Chen Guohua could come over to help review it.

At present, there are not many people in the mainland, or even around the world, who are qualified to review Erdesh's paper.

As one of the mathematical researchers studying the Riemann hypothesis, Chen Guohua is definitely the most qualified person.

In front of the office of the Department of Mathematics at Peking University, two students were rubbing their hands and breathing in the doorway, stamping their feet from time to time.

"professor!"

Seeing Chen Guohua get out of the car, Chen Shuxing and Bai Ronggen quickly stepped forward to greet him.

"Who asked you to wait here? Isn't it cold?"

Chen Guohua nodded slightly, but put away his smile and asked seriously.

Even though the two students here were several months older than him, even Chen Guohua paid little attention to them.

But that doesn't mean anyone can bully them both.

"No, Professor, we came down on our own, no one asked us to come down."

Bai Ronggen and Chen Shuxing quickly explained. Chen Guohua frowned and said:

"No one really forced you?"

"No, professor, we just have a few questions that we would like to ask you."

The two of them didn't waste any time and started asking questions directly.

And the reason why the two of them are like this is naturally not for self-abuse.

The main reason is that Chen Guohua is too busy. Many times, Bai Ronggen and Chen Shuxing are unable to ask him questions in person.

For example, in the past few times, every time Chen Guohua came to Peking University, his time was occupied by Erdez and other foreigners, or to be more precise, Erdez occupied his time.

Every time the wait ends, it's either dinner time or it's already dark.

As a result, where did Chen Shuxing and the two of them have time?

So, this time, they knew that Chen Guohua would come this morning, so they counted the time and waited at the door.

As everyone knows, Chen Guohua sends Yu Moli to Peking University every day.

Today is not the weekend or winter or summer vacation, so Chen Guohua will definitely send Yu Moli over.

The time when Chen Guohua arrives at Peking University is almost always fixed.

Therefore, Chen Shuxing and the two of them squatted in advance and were not very cold.

When Chen Guohua heard this, his expression softened a little.

At the same time, I felt warm and a little guilty.

To be honest, even though he made it clear to Chen Shuxing and Bai Ronggen at the beginning, he would not have a lot of time to devote to them.

As a result, he really didn't spend much time on the two of them to teach them to learn several mathematical tools in the Poincaré-Chen Guohua theorem as soon as possible.

It's been almost a year, and they are still messing around with these mathematical tools.

After all, he is their teacher, so he should be more or less responsible.

So Chen Guohua went directly to their offices without looking for Erdez.

The office of the Mathematics Department of Peking University is also filled with heating at this time.

However, Erdesh, Davenport, Selberg, and Homandel are already looking forward to it.

It can be said that the six of them, Selberg and the others, were all studying Erdesh's thesis, so they didn't find it very difficult.

Erdesh, on the other hand, couldn't wait any longer.

I hope Chen Guohua can help him review the paper as soon as possible.

As a result, I waited around and saw no one.

So Erdesh had to go to the office of the dean of the mathematics department next door to find Duan Xuefu.

After hearing this, the latter had no choice but to call Zhenhua Research Institute.

But Xue Yajun said that Chen Guohua did not come back to the institute today and had agreed to go to Peking University.

"Director Duan, please wait a moment while I look for Director Chen."

Duan Xuefu, who was on the other end of the phone, was a little puzzled when he heard this. How could he find it at this time?

Unknown to him, Xue Yajun had already found Chen Guohua through the pager.

Or to be more precise, found Long Kanghou.

Long Kanghou held the pager in his hand, and he directly informed Chen Guohua of the content on the pager.

They were all in the office where Chen Shuxing and the other five were. Seeing this situation, Chen Guohua asked Long Kanghou to call Xue Yajun directly, telling the latter not to worry and they would go find Director Duan later.

After learning the news, Xue Yajun called back to inform Duan Xuefu of the specific situation.

When the latter heard this, he was surprised: Is it so efficient?

Since Chen Guohua was not in Zhenhua Research Institute, how did Xue Yajun find the former?

You know, there is no such thing as a mobile phone now.

Duan Xuefu guessed that it was probably some black technology developed by Zhenhua Research Institute, right?

Otherwise, how could we find someone so quickly?

"Erdesh, Professor Chen has been found. He will come to you later."

Erdesh was surprised when he heard this:

"Have they really found Chen? They're not lying to us, are they?"

"Haha, don't worry, I've definitely found it."

Seeing that Duan Xuefu was so confident, Erdesh nodded.

After turning around and leaving the department chair's office, Erdesh happened to pass by Chen Shuxing's office.

Suddenly something occurred to me, so I couldn't help knocking on the door and went in.

In his opinion, since Chen Guohua is still at Peking University, the most likely places to go are the Department of Computational Mathematics and Chen Shuxing's office.

After Jiang Boju opened the door, Erdesh said in surprise:

"Chen, you are indeed here."

His guess was correct. Chen Guohua was indeed cut off by Bai Ronggen and the others.

There are several people in this office, including Jiang Boju, Li Jianshu and Chang Jinping.

All three of them were his students, and only Bai Ronggen and Chen Shuxing were students of Chen Guohua.

But in fact, many times, the five of them would come to Erdös for consultation on math problems.

Because apart from Chen Guohua's ability to answer the mathematical problems of Bai Ronggen and Chen Shuxing, Erdesh was also able to help answer them.

As for Duan Xuefu or other mathematics professors, they may not be able to answer it.

Either Hua Luogeng or Wu Wenjun, but both of them are at the Institute of Mathematics of the Chinese Academy of Sciences, so they are definitely not suitable.

Therefore, it is better to go directly to Erdez.

Therefore, the five of them, Chen Shuxing, are actually more students of Erdez.

"Erdesh, you're here, sit down for a while, and I'll answer their questions first."

After hearing this, Chen Guohua raised his head and smiled apologetically, and then continued the derivation and proof process for Bai Ronggen.

Erdesh nodded, he didn't mind.

After all, we have already waited so long, so there is no harm in waiting any longer.

As a result, the wait lasted for an hour and a half. By the time Chen Guohua arrived at the office next door, it was already ten o'clock in the morning.

Chen Guohua opened it and looked through Erdesh's manuscript, and suddenly frowned.

There are too many to read in a short time.

"Erdesh, can I take these mathematical manuscripts with me?"

"No problem, you can take it." Erdesh heard this and said generously.

He was not afraid that Chen Guohua would steal his thesis results.

This is not the first day they have met. As top mathematicians, each has his own pride.

How could he ruin his reputation because of such a small achievement?

So Erdesh didn't care about it at all.

Chen Guohua nodded when he heard this, took the manuscript and left.

The other party is a top mathematician, and he must have written down these mathematical formulas in his brain.

You only need to continue the derivation again, and the proof process of this third small problem can definitely be verified again.

Jiang Boju, Chen Shuxing, and Bai Ronggen were astonished when they saw that Chen Guohua had directly taken away so many mathematical manuscripts.

Good guy, this is an extremely precious manuscript, just take it away?

Isn’t it too casual?

However, Chen Guohua and Erdesh are both top mathematicians, and their memories are very terrible. Naturally, they don't care much about mathematical manuscripts.

I guess only ordinary people like Jiang Boju and others would think that mathematical manuscripts are so powerful, right?

The SUV came out of the gate of Peking University and drove into Zhenhua Research Institute not long after.

In the office as warm as spring, Chen Guohua was busy calculating something, while Qiu Zongyue left shivering.

"Guohua, why are you here in the office today? Didn't you go to the laboratory?"

"The leader is here, please sit down first and wait for me."

Chen Guohua said without raising his head, then hurriedly wrote a few formulas, and then raised his head.

Qiu Zongyue came to see him this time mainly because he wanted to ask about the home version of the game console.

The home version of the game console has been mass-produced since September. Whether it is a game console or a cartridge, the monthly output is 50,000 units.

It is now early November, and the inventory has exceeded 100,000 game consoles and 100,000 cartridges.

The inventory pressure is high, which makes Qiu Zongyue a little impatient to wait.

"Leader, haven't we already said this before?"

Chen Guohua said helplessly after hearing this:

"The home version of the game console is definitely a more terrifying product than the game arcade machine. I asked you to train more workers, but you are not happy."

"We only have 100,000 game consoles in stock now. I'm worried that the demand will be so great that we won't be able to supply, and others will take away the market."

When Qiu Zongyue heard this, he immediately stared and said:

"Who dares to steal it? Who can steal it away?"

In response, Chen Guohua rolled his eyes and said:

"Leader, you don't think that no one has copied the "Ping Pong" arcade game since it was launched on the market for so long, right?"

"Or do you think that everyone is stupid and doesn't know how to develop a home version of the game console?"

"By the way, boss, have you received any news from China Resources?"

Seeing that Chen Guohua changed the topic directly, Qiu Zongyue felt helpless and had no choice but to talk about the latest actions of IBM, Texas Instruments and other companies.

This year's North American market, or the global electronics market, is a turbulent year.

With the emergence of electronic products such as Huaxin radios, photolithography machines, and "Ping Pong" game arcade machines, the entire electronic product market has ushered in dramatic changes.

IBM, as the original giant in the electronic product market, has now been replaced.

Although photolithography machines are not considered electronic products, they are also equipment in the upstream industrial chain of electronic products.

Therefore, the king of this year's electronic product market is undoubtedly China Resources.

Semiconductor City and IBM in Moscow each came up with imitation calculators, but they were still beaten by the Huayue calculator and were unable to resist.

Now these two products have withdrawn from the market, and currently only Huayue calculator is still rampant.

However, it is not as popular, because there is still some time before the market is saturated, but it is not very far away.

To put it simply, the price is still too expensive for ordinary people.

The price of US$399 is still a high-end product for many consumers.

Can't afford it!

Since it has been confirmed by their eyes that it is not a product they can afford, it is normal for the market to be saturated and sales to drop sharply.

Even so, facing this big global market, with a monthly volume of 300,000 units, there is still no big problem.

Chen Guohua is not sure how long such output can be maintained.

But it has been launched since September last year, and it has been more than a year now.

Currently, the number of Huayue calculators in the global market is around four million.

This data is much higher than the sales volume of Anita calculator, which is only tens of thousands units.

Also because the two opponents in Moscow and IBM were not very good, the professional calculators, graphing calculators, statistical calculators and other backup tools prepared by Chen Guohua were completely useless.

Therefore, these calculators have not yet been launched on the market, and even the inventory is only tens of thousands of units.

It’s definitely not for sale here in the Mainland yet.

Only Huayue calculators appear in many units. As for professional calculators, they can only be seen in a few scientific research units in the mainland for the time being. They are invisible to other factories and other units.

They also don’t have access to these professional equipment.

More importantly, Chen Guohua hopes to keep these professional calculators secret from foreigners.

Otherwise, if the mainland has not yet sold it, but someone abroad has already taken the lead in producing and selling it, it would be really nonsense.

In addition to Huayue calculator, proximity lithography machines are also very competitive in the international market.

However, due to the need to produce 78 photolithography machines, it will definitely not be possible within this year.

In particular, Pandelela Semiconductor's order for twenty photolithography machines will not be completed and delivered until at least next year.

And the "Ping Pong" game arcade also has no competitors in the market.

Because China Resources' products are so effective, IBM has begun to counterattack in a very targeted manner.

The news that China Resources learned from North America was that when IBM's Winkelman went to Princeton University, he talked with people about the two major mathematical theories of discrete system theory and sampled data system.

Chen Guohua was suddenly surprised.

Because, in the 1950s, the progress of research on sampled data systems and the development of discrete system theory laid the mathematical foundation for digital signal processing.

But according to the history of the original space and time, it should be in 1965 that Cooley and Tukey first proposed a fast algorithm for the discrete Fourier transform, that is, the fast Fourier transform.

In this way, the number of operations of the discrete Fourier transform can be greatly reduced.

Only this breakthrough led to a major turning point in the concept and implementation of digital signal processing.

And at the same time, digital filtering theory using computers to approximate and simulate analog filters was also developed.

Therefore, the emergence of fast Fourier transform and digital filtering theory formed the two pillars of digital signal processing.

Is this the history of the original time and space, but now, because Winckelmann went to Princeton University, the center of mathematics in North America, and then started to make a dramatic breakthrough?

You know, the current large-scale integrated circuits have exceeded the history of the original time and space.

Therefore, as long as these two major mathematical theories appear, the emergence of digital signal processing technology will not be far away.
