The passionate years starting from the college entrance examination

Chapter 213, arrived as scheduled (please vote)

"Director Chen, I finally see you."

Hearing the movement, Chen Guohua looked back and was suddenly surprised.

Several people came to the door, Dai Xizhang, Zhao Zhongyao, and Xi Deming were among them.

These people are all completely unrelated to each other, yet they all get together.

Almost instantly, Chen Guohua's brain was running at high speed.

It was obvious that whether they happened to meet each other or for other reasons, as long as they came, nothing good would happen.

Fortunately, Chen Guohua had almost finished lunch.

Therefore, after eating, he took Dai Xizhang and the others back to the office to see what they were doing.

"Director Chen, you are not kind. If I hadn't learned from Lao Xi that your research institute has come up with a very good cathode ray tube material, I wouldn't have known about it."

As soon as he sat down, Dai Xizhang said resentfully.

When Chen Guohua heard this, he looked at the other party strangely and said:

"Director Dai, you should know that Team Leader Xi is in charge of the oscilloscope project, and the cathode ray tubes they use are not very advanced. Aren't your Ninth Institute engaged in aero-engine research? Why do you need this?"

"Director Chen, my Director Chen, have you forgotten that the full name of our ninth institute is the Beijing Aviation Technology and Production Organization Research Institute?"

When Dai Xizhang heard this, he couldn't help but correct it.

In other words, what their Ninth Institute needs is all the equipment on the aircraft.

On an airplane, in addition to an aeroengine, a display is also needed in the cockpit.

And these monitors are not just any monitors, and the cathode ray tubes in Xi Deming's oscilloscopes are actually not what they need.

However, Dai Xizhang heard that Chen Guohua and the others had other products.

Zhenhua Research Institute is currently developing projects such as CNC machine tools, which also require cathode ray tubes.

Different machine tools naturally require different displays.

For aircraft, of course they need to customize different displays.

The planes in Moscow almost all have mechanical buttons and no displays.

Dai Xizhang and the others had already obtained part of the aircraft design plan, which required the use of computers.

For example, air pressure display, etc., all need to use these components.

"Okay, okay, I get it."

After listening to Dai Xizhang's explanation, Chen Guohua spread his hands helplessly.

"I have a lot of things going on lately, and I can only take care of myself. I really can't take care of you, Director Dai."

Saying this, why did he take the initiative to contact Dai Xizhang?

Even for the titanium alloy material developed last year, Dai Xizhang happened to come across the Beijing Iron and Steel Works, and then he shamelessly took advantage of this trend.

"Director Chen, I'm just being shameless. Can you let me take a look at any new technological inventions you have in the future?"

Chen Guohua shook his head and said:

"No, some technologies still need to be kept confidential."

"No, it's just my own opinion, no one else will know."

Dai Xizhang hurriedly explained, really afraid that Chen Guohua would misunderstand.

In fact, he really wanted to know about some products of Zhenhua Research Institute.

If they can use it in the ninth institute, then they don't need to study it anymore.

"Let's talk about it then. We haven't had any breakthroughs recently."

After thinking about it, Chen Guohua said.

Their Zhenhua Research Institute is not a garbage dump. How can they let the other party pick and choose?

Although it is now about mutual help, Chen Guohua can only give priority to his own side instead of considering other units.

The more people know, the more risks there are.

So let’s fool around first.

Seeing this, Dai Xizhang could only sigh.

Next, he paid attention to Shi Jiayi, Fan Zhilun and Shen Zhiyang.

"Oh, Xiaoshi and the others, Director Dai, go and take a look for yourself. I've been very busy recently and haven't even been able to take care of them."

After hearing Chen Guohua's words, Dai Xizhang's expression became even more resentful.

The former said in December last year that after Shi Jiayi and the others came to Zhenhua Research Institute, Chen Guohua definitely had no time to talk to them.

At that time, Dai Xizhang was still thinking that no matter how much he ignored him, he should at least visit him once a month, right?

After all, they are within the Zhenhua Research Institute and have also established aerospace engine testing.

In the end, Chen Guohua really didn’t take a look?

Is it really that busy?

With doubts, Dai Xizhang left first.

After Dai Xizhang left, Xi Deming began to talk about him.

What the latter said is not a troublesome matter.

I just came to inform Chen Guohua that they have built five different oscilloscopes and have sent them to the northwest.

"So fast?"

Hearing this, Chen Guohua was suddenly surprised.

In fact, it was indeed a bit fast, beyond his expectation.

You know, it's not even May yet.

According to the original plan, it would be great to be able to develop an oscilloscope before June.

Last month, Chen Guohua also went to the Second Department of the Institute of Physics to assist them in the research and development of probes and other components.

Now it's nearing the end of April and they're done?

"I'm not happy, haha. After Director Chen and you helped solve those components, we are still delayed until now. It's already very slow."

Xi Deming said modestly.

In January, Chen Guiying and other researchers who had returned from the Great Northwest began to develop the oscilloscope only after they were all in place.

By now, almost four months have passed.

In addition, Zhenhua Research Institute also helped solve many component and technical problems, so it was indeed a bit slow.

"So, in the northwest, can we now start a simultaneous research and development project focusing on technology?"

Chen Guohua did not continue to worry about the problem of the oscilloscope, but asked more questions.

Once the synchronized focusing technology is completed, the time to detonate the Demon King will be closer.

"Not yet!"

At this time, Zhao Zhongyao next to him said:

"The electron multiplier has not been developed yet, and the ignition neutron source device has not been developed yet, so I came here today to ask Director Chen if you can help me?"

When Chen Guohua heard this, he immediately spread his hands with a wry smile and said:

"Professor Zhao, do you think too highly of me? That is an ignition neutron source device. How could I do that?"

"No, Director Chen, I remember that you completed the manufacturing process of the ion source before. It shouldn't be a problem for you."

Zhao Zhongyao's words immediately made Chen Guohua roll his eyes.

Ignition neutron source and ion source are completely different things, completely unrelated, okay?

This thing is actually the neutron source material used to trigger the mushroom egg chain reaction.

It involves radioactive substances and light nuclear elements in the periodic table of elements, and extraction alone becomes a big problem.

And what is the ion source?

An ion source is simply a device that can ionize neutral atoms or molecules and draw an ion beam from them.

The two devices are simply not on the same level.

Moreover, as early as 1959, Wang Fangding and others began to develop an ignition neutron source.

In 1957, based on the new defense technology agreement in Moscow, Wang Fangding and the others were learning Russian while studying the 'fission product analysis' topic set by Mr. Qian.

Just because when detonating the Demon King, many measurements will use this fission product analysis.

As one of the key components of the mushroom egg, the ignition neutron source has a total of three technical lines.

Wang Fangding and the others are responsible for one of them, and it is also the most successful route in the original time and space.

According to the path of the original time and space, Wang Fang decided that they would complete the development of all ignition neutron sources five years later, that is, in 1964.

It is now 1961, and there is still a long time before they complete the project.

But Chen Guohua, a half-way monk, went to work on this project?

Ha ha!

I really don’t know what Lao Zhao thinks.

"Professor Zhao, I did develop the ion source and the accelerator, but I don't understand the chemical research on radioactive substances."

Chen Guohua hurriedly explained to Zhao Zhongyao.

It's not that he doesn't want to help, it's just that this thing is too dangerous, and he agreed that he would only provide support.

As a result, Chen Guohua took part in all the ion sources, accelerators, oscilloscopes, mathematical problems of spherical bodies, etc.

Including computers, Chen Guohua is already one of the main contributors to the mushroom egg scientific research project.

However, the ignition neutron source is really not what Chen Guohua is good at.

Wang Fangding and the others have no shortage of craftsmanship. After all, they have already decided on three technical lines.

Mr. Qian has the skills in this area and is not lacking in manufacturing technology.

The key difficulties lie in raw materials and experiments.

Now, Wang Fangding and the others are conducting experiments in a simple shed simply because it is the most flexible and can quickly build a house.

The interior decoration of the entire work shed is as follows: paint the ceiling and walls, lay rubber on the floor, set up a glove box, install a strong ventilation fan, etc.

And one thing we all know is that when Madame Curie discovered radium, she did it in a work shed. This is a good story in the scientific community.

It is quite difficult to go to such a place to conduct experiments.

Just imagine, in the dog days of summer, you have to wear three layers of protective work clothes and two layers of rubber gloves, sweating profusely every day; in winter, the weather is so cold that the water pipes are frozen and cracked, and you have to conduct experiments, which is very difficult.

Anyway, Chen Guohua is not suitable to engage in such research.

The only thing Chen Guohua can do to help is to provide them with more powerful computers or mathematical calculations.

After hearing Chen Guohua's words, Zhao Zhongyao sighed.

In fact, he was just talking about it, and he didn't dare to expect that Chen Guohua would actually go.

Moreover, if Chen Guohua really goes there, Zhao Zhongyao will still have to worry about being scolded by Qiu Zongyue.

You know, after Chen Guohua left, Zhenhua Research Institute was almost abandoned.

Nowadays, although the scientific research task of mushroom eggs is very important, Zhenhua Research Institute cannot give up.

What's more, Chen Guohua has developed an integrated computer and will have a chip with better performance around July this year.

By then, it is not impossible that the computing speed of supercomputers will exceed 500 million, or even one billion.

Based on this, it is impossible for Qiu Zongyue and other leaders to let Chen Guohua leave Zhenhua Research Institute.

In addition, today's ignition neutron source devices actually have many more researchers, and the research and development speed has been accelerated a lot.

At present, there is no shortage of raw materials such as uranium 235. Now we are waiting for the completion of the synchronous focusing technology, coupled with the ignition neutron source and other related devices, to proceed to the final step.

The reason why Zhao Zhongyao mentioned this matter to Chen Guohua was because he knew the latter's innovative ability in scientific research projects and hoped that Chen Guohua could help with the most difficult aspect of the ignition neutron source device.

After all, with the help of Chen Guohua, the research and development speed of accelerator, ion source, oscilloscope and other projects has been advancing by leaps and bounds.

Unfortunately, the ignition neutron source device was started the year before last, and it has been almost two years now. It has not been completed yet, and everyone is anxious.

There is an urgent feeling that everything is ready, all that is needed is a lighter.

Xi Deming sat aside and said nothing.

At this time, Chen Guohua said nothing more after explaining.

Then Zhao Zhongyao talked about a few more technical issues and left with Xi Deming.

After watching them leave, Chen Guohua shook his head. He didn't take this matter to heart.

Regarding the matter of the ignition neutron source device, the higher-ups are more anxious than Chen Guohua.

With the support of supercomputers and the oscilloscopes and other equipment already in place, more professional chemists, physicists and mathematicians will be dispatched to this project to complete the research and development of the ignition neutron source device. Task.

And, judging from the current situation, the technology project that Wang Fangding and his team are working on is the most likely to make a breakthrough.

So if Mr. Qian and the others were not stupid, they would definitely send more people to help Wang Fangding.

Chen Guohua will not underestimate the world's heroes. What he can do is to do his own job well.

In other respects, he would help as much as he could.

He couldn't help, so he was helpless.

In the afternoon, Xue Yajun continued to learn about Zhenhua Research Institute, while Chen Guohua was stopped by Dai Xizhang on the way to the laboratory.

The latter chatted with Shi Jiayi, Shao Fuqi and Fan Zhilun. Chen Guohua came once after the Spring Festival, but has not come again until now.

It's actually a bit too much.

But so what?

Chen Guohua has already said that he does not come to the aerospace engine laboratory often.

But now that Dai Xizhang has come forward in person, Chen Guohua has to give him some face.

"Director Chen, please give me some face. When will you give them a chance to assess their current learning progress? After all, almost five months have passed since December."

In the aerospace engine laboratory, Dai Xizhang said earnestly.

Although Shi Jiayi and the others are now researchers at the Zhenhua Research Institute, no matter how you look at them, they are more like people from the Ninth Institute.

Of course, this may be because Chen Guohua and I don't come here often, so they don't have much sense of belonging.

It is also because Dai Xizhang is standing aside and working hard for the aviation industry that he gives Chen Guohua such an illusion.

"Professor Dai, it's not that I'm not happy to assess them, but as you know, I'm very busy now."

Chen Guohua spread his hands and said:

"Also, even if they pass the assessment, I don't have time to arrange their subsequent research and development work."

"Currently, there are only eight of them. The most suitable job is to study. If we leave other tasks to them, they will not be able to do it."

Of course Dai Xizhang knew this, but he was still unwilling to do so.

"Then we can also let them do some design work, or is there any way to speed up their learning?"

After hearing Dai Xizhang's words, Chen Guohua shook his head and said:

"Professor Dai, you may not know the tradition of our Zhenhua Research Institute. I am responsible for all technical information."

"So when it comes to engine design or aircraft design, we actually have no shortage of it."

"For our Zhenhua Research Institute, what we lack most are technicians, R&D personnel, etc."

"Whether we build aircraft or other equipment, at Zhenhua Research Institute, I take the lead, assign tasks, solve technical problems, and overcome difficulties."

Dai Xizhang was immediately taken aback, dumbfounded and said:

"Is it possible that so many scientific research products are developed in this way?"

Good guy!

According to Chen Guohua, he alone takes most of the credit for most of the products produced by Zhenhua Research Institute.

What a surprise!

Although Dai Xizhang had been in contact with Chen Guohua several times before, he knew that the latter was a super genius who studied heaven and earth.

But he still underestimated Chen Guohua's strength.

"That's not entirely the case. I am the guide and most of the work is done by the researchers."

Chen Guohua was modest and then said:

"Professor Dai, I have my own plans for the aero-engine project. This summer, after I finish several projects, that is, in the second half of the year, I will start the aero-engine project."

"When the time comes, we will definitely need to cooperate with Professor Dai's Ninth Institute. I also hope that Professor Dai can help us."

Dai Xizhang was overjoyed when he heard this.

He nodded and agreed, but it was unclear whether he would regret it in the future.

Anyway, at present, Chen Guohua does not have the mind or time to take into account these projects.

Time flew by, and two days passed in the blink of an eye.

Xue Yajun has gradually become familiar with the work rhythm and style of Zhenhua Research Institute, and has slowly integrated into it.

For a new employee, Xue Yajun still has a lot to learn.

At least he still doesn't understand many of the rules in Zhenhua Research Institute.

Moreover, he is a man in his 40s and almost 50s. It is undoubtedly a challenge to change some of his previous work habits and re-adapt to the current working environment.

But he had to fit in quickly.

The best way to integrate into work is to actively participate in work, such as communicating more with Hou Sihe and doing the latter's ideological work.

After all, the May Day holiday is coming soon, and Hou Sihe needs to go back to meet Liu Chijing.

So how to carry out the follow-up work at that time is very important.

In addition, after catching Liu Chijing, how can the follow-up work be carried out faster? It is even more critical to catch the big fish behind Liu Chijing.

And there is also a need to file: What if Liu Chijing does not show up?

Only by making thorough preparations can you remain unchanged in the face of ever-changing situations. Chen Guohua was not involved in this. He only knew the results and did not want to know the process.

Fortunately, before the May Day holiday, Lin Zhiwu and the others had broken through the technical limitations and increased the yield to 82%.

This means that it does not take much time for Zhenhua Research Institute to provide a sufficient number of chips for delivery.

After Qiu Zongyue learned about this, he was very happy.

They asked Lin Zhiwu and others to work overtime, and each of them would be compensated with two kilograms of fatty pork.

This is additional compensation.

The May Day holiday will be moved to that time, and they will take the rest after completing their tasks.

Regarding this point, Chen Guohua just gave the choice to Lin Zhiwu and others, and he did not help them choose.

Moreover, they will not be forced.

However, in fact, even without the temptation of two pounds of fat pork, Lin Zhiwu and the others would choose to work overtime.

Just because of what happened recently, they were particularly nervous.

Knowing that chip manufacturing is urgent, chip engineers like Lin Zhiwu and others are naturally willing to take the initiative to work overtime.

Qiu Zongyue repeatedly praised them for their high ideological consciousness, unlike some people who only want to take a vacation.

Of course he understood Chen Guohua's connotation.

But he just rolled his eyes and didn't bother to explain.

Even though he was finally caught by Qiu Zongyue and asked to say a few words, Chen Guohua didn't lose a piece of meat.

What's more, Chen Guohua had complained about each other a lot before, so the two of them had a relationship.

In fact, the relationship between the two is no longer that of superior and subordinate, but more like friends who have been together for many years.

Chen Guohua's dedication and hard work are seen by everyone.

As the direct leader, Qiu Zongyue sees things more clearly.

Besides, Yu Moli's belly is already very big and she will give birth at the end of May or early June. It is only natural for Chen Guohua to want to take a vacation and spend more time with her.

The May Day holiday came soon, and Chen Guohua did not go back to work. He planned to spend the holiday with Yu Moli, and maybe go to the Summer Palace.

Nothing big happened at home recently.

The only major event was that his sixth sister Chen Guiying was finally pregnant.

According to the doctor, she should have been conceived during the Spring Festival, and it has been more than two months now.

Apart from this, there is nothing else.

Chen Lihua is still an older single lesbian, and she has not yet finished her blind date journey.

Everyone can finally understand that she just loves to play.

The SLR camera brought back by Chen Guohua has become Chen Lihua's exclusive camera.

When she was on vacation, she would bring her SLR camera and take photos and check-ins in the area with Chen Xiaoyue, Chen Yuanchao and other half-grown boys and girls.

Since she controls her own salary, her family does not lack her share of the salary.

So naturally she had money to buy film.

"Guohua, the digital camera you told me about is the kind of camera that doesn't require film. When was it developed?"

On the evening of the last day of April, at the dining table at home, Chen Lihua started her daily questioning again.

"Seventh sister, how can it be so fast? Even if we develop it, you will definitely not be able to use it."

Chen Guohua shook his head when he heard this.

"You can tell us, why can't you use it?"

"It's a confidential matter."

At this time, Chen Guiying suddenly replied, and her sister Chen Lihua's eyes widened:

"It's just a camera, what does it have to do with secrets?"

"This is a high-tech product. It will only be supplied to national defense, public security, news media and other related units as a priority. If you are an individual, you will definitely have to wait a little longer."

After a pause, Chen Guohua continued:

"The reason why I said you can't use it, Seventh Sister, is because you definitely don't have a computer. Without a computer, many photos cannot be processed."

"The photos taken by then can only be viewed on the small screen of the camera."

"And the most important thing is that due to technical limitations, digital cameras may not be able to take many photos."

This must have a lot to do with memory.

Even if digital cameras come out and are produced for personal use, the internal memory will not be very large.

This means that there won’t be many photos taken.

In this case, it would actually be better to use a film camera.

Of course, film cameras also require purchasing film, and this alone is enough to deter many people.

It's not yet certain what the future will be like. All I can say is, take it one step at a time.

When digital cameras come out, the situation outside may be different.

Maybe by then we can export digital cameras and earn foreign exchange?

Hearing Chen Guohua's words, Chen Lihua suddenly became depressed.

Yes, computers are one of the most important electronic products. Even if they can be purchased by individuals, the circuits at home may not be able to support them.

Another day, the family went to the Summer Palace to hang out.

After the experience on New Year's Eve, the family no longer goes to places with many people, but only places with few or even no one.

As for not hanging out at all, that is absolutely impossible.

The public security environment in Beijing is already very good, so there is no need to stop eating due to choking.

The Summer Palace in May has a nice environment and cool weather, making it the perfect time to go out and play.

Chen Wei, who can crawl on his own and is about to walk, is most happy to be in such an environment.

In a corner of the Summer Palace, Chen Lihua and the others took out a piece of cloth and spread it on the ground.

The whole family sat in this place, basking in the sun and chatting.

And the little guy Chen Wei was crawling on it, and he was so happy.

Then after a while, the little guy Chen Wei suddenly started to pee.

Yun Wanshang, who had quick eyes and quick hands, immediately picked up the little guy and put him directly in the small ditch next to him, letting the little guy pee by himself.

As your children grow up, you can help them get used to these things by developing habits.

However, when Chen Guiying saw this scene, she suddenly asked.

"Guohua, when will I receive the diapers you mentioned last time?"

"Sixth sister, we have to wait until the factory is built in Baiyun City before we can start production."

Chen Guohua said with a smile:

"I have mentioned this matter to the leader before, and the leader will help me follow up on this matter."

In fact, the diaper factory in Baiyun City is already being established.

But the collection of raw materials is still a big problem.

Of course, the subtropical climate in the south is very rich in resources.

In addition, they are close to Southeast Asia, so if they need any supplies, they can also be imported to Baiyun City.

However, it should be impossible to import, because importing will involve foreign exchange. But now the whole country is short of foreign exchange, how can it be possible to import these raw materials?

So the biggest possibility is that Baiyun City can solve the problem of raw materials by itself.

As we all know, the raw materials of diapers include non-woven fabrics, polymer materials, adhesives, tapes, protective films and elastic fiber materials.

These raw materials are not a big problem, but the current economic chain has not yet been established, so the acquisition of raw materials still needs to explore a new way.

Originally this should be a big problem, but if the leaders in Beijing pay attention to it, then it won't be a big problem.

"What kind of diapers do you want? Don't you think Weiwei is doing well now?"

Yun Wanshang said with a smile while picking up Chen Wei and placing him on the ground.

After the little guy peed a lot, he immediately started to get up again, and his giggles reached everyone's ears.

Chen Xiaomin also clapped her hands and asked the little guy to crawl towards her.

Seeing the little guy curiously exploring the world, Chen Guohua smiled and did not respond to his mother's words.

For now, it is still necessary to take out diapers.

As long as the technology is passable, it's not a bad thing for a kid.

On the contrary, it can save adults a lot of things.

If there are no diapers, a baby of one or two months will not be able to control his/her urge to pee.

In the past, Chen Wei, a child, had troubled the adults in his family a lot.

According to Chen Guohua, around eight or nine months old, you can start cultivating the habit of peeing and pooping on your little one regularly.

The May Day holiday passed quietly while chatting about these family matters.

The happiest thing about Chen Guohua is that no one bothers him during the holidays, which means everything is normal.

After the holiday, Chen Guohua returned to work and continued working.

During lunch time, Xue Yajun came to Chen Guohua to report on his work, mainly about Hou Sihe and the big investigation.

Yesterday was the May Day holiday. To be precise, on the last night of April, the arrest operation had already begun.

After Hou Sihe returned to his hometown, he also had dinner with his family before going to see Liu Chijing.

When Liu Chijing was arrested, there were no accidents and no one was injured.

And Yin Menglun and the others quickly interrogated the big fish behind Liu Chijing.

However, when they drove the boat to the open sea, many people escaped because of darkness.

But during the day the next day, they still caught several big fish from the sea.

One of the big fish turned out to be Cleo, the latest head of a certain department.

This big fish was handed over by Yin Menglun and others, and the relevant departments, the foreign affairs department and other relevant departments are currently following up on the matter.

Therefore, Hou Sihe made a great contribution this time.

According to the above meaning, treatment is arranged for Hou Dachang, but I really don’t know whether he can be saved.

In fact, Xue Yajun and the others should report this matter to Chen Guohua as soon as possible.

But the latter had already said before that there was no need to notify him specifically about this matter, he could just report it directly to his superiors.

He just needs to know the results.

Therefore, Chen Guohua had no objection to the above arrangement.

In addition to Hou Sihe's matter, it is also a matter of getting to know all the members of the Zhenhua Research Institute.

Not to mention, there are indeed many researchers whose families are living in misery.

There are many people like Lin Jixiang who have lost their mother at home, or people like Hou Sihe whose father is seriously ill.

This situation doesn't mean anything.

But it definitely needs to be focused on, especially for researchers whose families live in areas around the capital.

On the contrary, those researchers whose hometown is in the south or other places are less likely to be bribed.

The main reason is that communication in this era is extremely underdeveloped.

If those people want to bribe researchers whose hometowns are in rural areas deep in the mountains and forests, trust alone will be difficult to solve.

After all, the researcher needs to contact his hometown, which can only be done through letters or telegrams.

This undoubtedly increases the risk.

Therefore, after the thorough investigation, Chen Guohua and Xue Yajun had a clearer understanding of the situation of these researchers.

As long as you pay a little attention to this type of researcher, you can follow the clues if there is any trouble.

However, it is impossible for everything in this world to develop according to plan.

For Chen Guohua, he felt a lot more relaxed after having Xue Yajun as his second-in-command.

For these two things, Chen Guohua only needs to be informed, and he doesn't need to worry about other things.

"Old Xue, you have really helped me a lot. From now on, I will completely leave these matters to you, and I will completely let go."

After listening, Chen Guohua said with a smile.

Hearing this, Xue Yajun was modest and immediately said that he would definitely do his job well.

He had already established his position and changed roles very quickly.

As a result, Chen Guohua felt much more relaxed in the next period of time.

After unloading these tedious tasks, Chen Guohua spent a lot more time traveling between various laboratories.

The scientific research results of these laboratories appear almost one after another.

The temporary laboratory that manufactures chips has successively delivered chips from several foreign companies. Lin Zhiwu and the others are still working hard to prepare for the rapid delivery of the remaining chips.

The two major technologies of aluminum gallium arsenide semiconductor laser and excimer laser have also made breakthroughs one after another.

They are both lasers, and the technologies are closely related. The reason why they made breakthroughs one after another is because the two major laboratories cooperated with the equipment research and development laboratory, and there were frequent exchanges between the two parties.

"You take this aluminum gallium arsenide semiconductor laser back to your laboratory and seize the time to understand the technology of other auxiliary equipment for fiber optic communications."

Chen Guohua ordered.

There are many researchers in the Optical Fiber Communication Laboratory. After all, their laboratory has many tasks that need to be completed.

The gallium aluminum arsenide semiconductor laser in front of us is just one of the equipment used to prepare optical fiber communications.

There are still many technologies waiting for them to break through.

After they left, Chen Guohua looked at the R&D personnel in the lithography machine laboratory and said:

"Next we will start to improve the light source technology."

Previously, the light source used in the lithography machine developed by Chen Guohua and others was a mercury lamp.

This thing can produce blue light with a wavelength of 400 nanometers and invisible ultraviolet light of 360 nanometers. This is the light source of the first-generation lithography machine.

Now, what Chen Guohua and the others need to develop is a second-generation light source.

First of all, in terms of the way of light emission, it is not the previous mercury lamp, but a laser.

Since it is a laser, a different laser is needed.

"Come on, Lao Zhang, you still remember the deep ultraviolet excimer laser I mentioned to you before, right?"

Chen Guohua clapped his hands to attract everyone's attention.

However, before Zhang Jichuan and the others could respond, Chen Guohua continued:

"Let's not talk about how to prepare deep ultraviolet excimer lasers. Let's talk about the technology of excimer lasers."

The excimer laser has just been developed, what else is there to say?

But everyone listened very carefully.

After all, Chen Guohua would never make a mistake without aim. There must be a reason for him to say so.

In the original history of space and time, the excimer laser was invented at the Moscow Institute of Physics in 1970.

This thing uses electron beams to excite xenon dimers, and the excimer laser produced has a wavelength of 172nm.

Then in 1975, several institutions including the North American Naval Research Laboratory, Northrop Research and Technology Center, and Sandia National Laboratories used electron beams to excite noble gas halides.

It was not until 1979 that the first commercial excimer laser was produced in West Germany.

In today's time and space, Chen Guohua and others directly tried ten kinds of gases that can produce excimer lasers during the research and development process.

However, there are currently only two types of gases that have been successful, and the research and development work on the remaining eight gases will not end, but requires further research and development.

In other words, they now have two gases that can produce excimer lasers.

"What do you think this excimer laser can do?"

Looking at the crowd, Chen Guohua first reviewed the excimer laser technology, and then asked another question.

Zhang Jichuan immediately raised his hand and responded:

"Director, I know that this can be applied to photolithography machines. In addition, I think it will also be of great use in optical lenses."

"Yes, that's right. Is there anything else?"

Chen Guohua looked approvingly, but he was even more looking forward to the answers from other researchers.

Needless to say about the lithography machine, after all, this excimer laser was manufactured and developed for their lithography machine laboratory.

This function of optical lenses is also a trick played by Zhang Jichuan. After all, Chen Guohua has taught everyone about the application of photolithography machines before.

Following Chen Guohua's questions, many researchers were thinking hard.

Someone also answered Chen Guohua's question, some were right and some wrong, but it made Chen Guohua a little bit dumbfounded.

The knowledge base of these researchers is still too narrow.
