The Red Era, the Opening University Speech

Chapter 465: Being Acted

Hu Xuhua didn't finish his words.

But the result is self-evident.

It was obvious that the director of the Baltic Shipyard would never agree to Hu Xuhua running around, and he definitely did not agree to it.

But in the end, someone took advantage of the loophole.

Li Mu reasonably suspected that when Ding Xiuxun heard the news, Hu Xuhua had already arrived at the train station.

He said helplessly: "There's no need to do this!"

"It is necessary, Consultant Li. You don't know that on the seventh day after you left, we encountered huge difficulties..." Hu Xuhua said with a long sigh.

When Li Mu left the Bohai Shipyard.

They said they would follow.

It was just a joke at the time.

After all, Kyoto's geographical environment is not suitable for the development of submarine-launched D missiles.

And they also took the plan given by Li Mu.

If I chase after him and ask for help, it would seem too incompetent.

It took more than ten days to study.

They finally discovered that they and others really had no way to solve most of the development problems of the submarine-launched D missile.

Theoretical problems are not serious.

But once we start formal research and development, we will encounter various problems.

"Okay, now that we're here, I'll take you to sit with Director Wu Youxiang of the Semiconductor Research Institute first, and I'll go over there later." Li Mu thought for a moment and said.

Everyone has arrived.

It's impossible to send it back immediately.

He also wanted to hear about the development plan for the submarine-launched D missile.

Of course, there is also the development of sound-absorbing tiles and sound-absorbing coatings.

Hu Xuhua nodded, knowing that he was still working, and immediately said:

"it is good."

……

Subsequently.

Li Mu took Hu Xuhua to the Semiconductor Research Institute.

It is definitely not so easy for ordinary outsiders to come in.

But with him as a guarantor, it won't be a difficult matter.

After checking the documents, the guard let us go.

After Guan Jianmin parked the car on the open space in the station.

The two got out of the car.

As soon as it comes out.

Hu Xuhua looked at the magnificent buildings of the Semiconductor Research Institute and the researchers shuttling back and forth inside and out.

There was a pilgrim-like admiration in his eyes.

Although the Baltic Shipyard is also very large.

But to be honest, its fame cannot be compared with that of the Semiconductor Research Institute.

Don't say anything else.

A supercomputer.

This place has become a holy place in the minds of all Xia scientists.

Just when he was filled with emotion.

Suddenly I saw a familiar-looking person and said:
"That's Professor Huang, right? I've seen him in the newspaper. He's an expert in semiconductors!"

"Yes, it's him." Li Mu said with a smile.

While the two were talking.

Huang Xinhua also saw them, walked up and asked curiously:

"Who is this?"

"Professor Hu from the Bohai Shipyard came to see me." Li Mu nodded.

Following his introduction.

Hu Xuhua stretched out his hand, shook Huang Xinhua's hand vigorously, and said:
"Professor Huang, I have always wanted to meet you and thank you in person."

"Thanks to your contribution to the semiconductor field, our country's scientific development has made such great progress."

"Even my research project has benefited from your achievements and has made some progress, bringing me one step closer to surpassing Emperor M and Big Brother."

His eyes were full of gratitude.

It is known throughout the country that it was the mysterious River Map that created the advanced computer.

But what they don't know is.

If it weren’t for Hu Xuhua’s contribution to integrated circuits.

There would be no breakthrough in computers like Hetu.

If the River Map built a building.

Then Hu Xuhua is the person who provides the most solid and best-use materials for this building.

"Haha, Professor Hu, you misunderstood. I don't have such a great contribution." Huang Xinhua waved his hands quickly.

Hearing this, Hu Xuhua thought he was being modest and said:

"You don't have to be modest. Without you, how could our country be so powerful in the computer field today?"

"You really misunderstood." Huang Xinhua didn't know whether to laugh or cry for a moment, and said, "That's all thanks to Hetu."

After he finished speaking, he paused slightly and glanced at Li Mu.

However, Li Mu's identity was not revealed.

After all, even if Hu Xuhua is a scientist of the same level as Master Qian Wu.

Without permission.

It is also impossible to know this information which has been sealed as a top secret file.

"Aren't you a member of Hetu, or are you related to it?" Hu Xuhua was a little shocked.

He always thought that Huang Xinhua was a member of Hetu.

After all, supercomputing is a huge research project.

It cannot be accomplished by one person, or even just a few people.

Instead, it takes a team of at least dozens of people working day and night to see results.

Huang Xinhua explained:

"No, I just do some research in semiconductors."

"As for who Hetu is and who he is related to."

"You should know that you absolutely cannot say this."

After he finished speaking.

Hu Xuhua said quickly:

"You're right, I was too rash. I'm sorry."

Even if a little information was leaked about the supercomputer developed by Hetu, it would be enough to shock Emperor M and Big Brother.

In this situation, identity is naturally extremely sensitive.

However, he couldn't help feeling a little regretful when he thought about coming to the Semiconductor Research Institute but not having the chance to see the famous Hetu.

……

While talking.

The three of them came to the director's office.

He raised his head and knocked on the door.

Without waiting for the person inside to respond.

Li Mu pushed the door open with a "creak" and walked in.

Wu Youxiang, who was about to get up and open the door, saw Li Mu coming in, smiled and said:

"Here he comes."

"Well, this is Professor Hu from the Baltic Shipyard. He came over there to find me and will stay here for a while." Li Mu explained briefly.

After listening to what he said.

Wu Youxiang said immediately:

"Just go and do your thing. I'll entertain you and I will definitely not neglect Professor Hu."

He said as he spoke.

While moving swiftly, he went to the wooden cabinet on the inner wall of the room and took out tea leaves to make water.

Seeing this, Li Mu gave Hu Xuhua a few more instructions.

Just walked out.

Huang Xinhua also hurried to follow.

……

After the two of them left.

Wu Youxiang and Hu Xuhua were the only ones left in the office.

Although I haven't seen it.

But they weren’t awkward either.

Wu Youxiang handed over the brewed teacup and said with a smile:
"Professor Hu, have some tea."

"Thank you, Director Wu. You're welcome." Hu Xuhua said quickly.

I felt a little reserved when I saw him.

Wu Wangxiang continued:

"By the way, Professor Hu, I wonder what you want to talk to Consultant Li about this time?"

He knew that Li Mu had gone out some time ago.

However, I have no idea where he went, what he did, or when he returned.

"I would like to ask Consultant Li for help and guidance on my research." Hu Xuhua said concisely.

Same as Huang Xinhua.

When confidential information is involved.

He also remained highly alert.

Wu Youxiang paused and asked doubtfully:

"Ask Consultant Li? I'm afraid he won't be able to spare the time for quite some time."

Although I don’t know about Li Mu’s work situation.

But judging from the time he stayed at the Semiconductor Research Institute each time.

Wu Youxiang could still infer that Li Mu must be very busy.

under these circumstances.

Unless it is a project of the same level as the Big Mushroom, it would be impossible for him to leave Kyoto easily.

"Of course we know. So I came here this time to plead with Consultant Li and see if the research project can be transferred here." Hu Xuhua said.

There is no Li Mu.

The impact on the development of the entire submarine-launched D missile is huge.

They discussed and calculated this once or twice.

The results all show that if Li Mu could provide guidance, the research speed could be increased by at least 3%.

Don't think this is too little.

In the research projects such as submarine-launched D bombs, which often take years.

3% will take one or two years, or even three or four years!

"Transferred to Kyoto! Are you coming alone, or are there many experts who want to come too?" Wu Youxiang's eyes lit up and he asked hurriedly.

Hu Xuhua thought for a moment and said:

"Don't worry about your laughing, but our entire research team wants to come."

"You have known Consultant Li for such a long time, you should know his abilities better than we do."

"With him, we can make the project a success faster!"

The whole team?

Wu Youxiang couldn't help but be stunned. He finally understood why Hu Xuhua said he wanted to plead with Li Mu.

After all, both the people and the project were taken away together.

He would be the director of the Baltic Shipyard.

I'm afraid he'll be so angry that he'll curse.

Thinking of this, Wu Youxiang hesitated and said:
"Actually, there's no need for everyone to come."

"If it's just a certain group of people, I think it's fine."

"I can even help you stay at the Semiconductor Research Institute so it will be more convenient."

When he heard that Hu Xuhua wanted to come to Kyoto.

We really want to bring people to the Semiconductor Research Institute.

But it’s no problem to pull one person.

It’s still a bit scary to form a team.

After all, he didn’t know whether the director of the Bohai Shipyard would scold Li Mu, but he would definitely fight him to the death.

"If you can help, that would be the best." Hu Xuhua said with a look of joy on his face.

……

outside the office.

in the corridor.

Just when Wu Youxiang and Hu Xuhua were chatting enthusiastically.

Li Mu and Huang Xinhua also walked to the vicinity of the laboratory.

But neither of them went in.

Instead, they were outside talking about the development of integrated circuits.

Huang Xinhua said:

"Based on the method you provided last time, we have now made considerable progress in photoresist."

"The two steps of introducing cross-linked structure and rigid molecular structure have also been basically completed."

“However, it will take quite some time to establish a suitable resin system. There is still room for improvement in the two-component resin and gradient distribution design…”

He briefly explained the situation.

Of course, in addition to the method provided by Li Mu.

They are not without breakthroughs.

For example, by increasing the post-baking temperature, the resin's reaction can be promoted and the mechanical strength can be enhanced. Another example is controlling the developing conditions to reduce the excessive erosion of the developer on the resin and protect the integrity of the structure.

By adjusting the photolithography process conditions, the mechanical strength and etching resistance can also be indirectly improved.

Even to Li Mu's surprise, the idea of ​​a layered design was proposed.

"Use a multi-layer photoresist structure, with low molecular weight resin as the top layer and high molecular weight or anti-etching resin as the bottom layer. Do you think it is feasible to directly isolate performance requirements through physical layering?" Huang Xinhua asked.

Li Mu smiled and said:

"Of course it is feasible, but to achieve it, we need to overcome many difficulties."

“Different photoresist layers need to have good adhesion to avoid interlayer mixing or interface defects.”

"There is also the issue of process compatibility. Solvent erosion and mismatched thermal expansion systems may affect the finished product..."

He expressed his opinion.

Layered design, also called multi-layer photoresist technology.

However, this technology has significant advantages in theory.

In actual application, there are many technical difficulties and equipment requirements.

In addition to the above problems.

There are also issues such as the balance between resolution and thickness and defect control.

In addition, special machines are also needed to support the equipment.

For example, high-precision spin coating machines or spray coating equipment, high-precision exposure machines, high-precision developers, etc.

Overall.

The effect is good, but the cost is also high.

"Since you said so, let's think about it carefully." Huang Xinhua said decisively.

In his mind, what Li Mu agreed to might not necessarily be a problem.

But if you think something won’t work, it definitely won’t work.

Hearing this, Li Mu thought for a moment and said:

"The technology is there, but it's hard to realize right now. We can study it first and see if it's possible later."

……

It took about two hours with Huang Xinhua.

The problems encountered in photoresist, mask technology and optical system.

After guiding and giving directions one by one.

Li Mu returned to the director's office.

However, what he didn't know was that Wu Youxiang and Hu Xuhua had also reached a consensus at this time.

……

Push the door open.

Li Mu walked quickly into the house.

Look at the sofa.

I was a little surprised for a moment.

Hu Xuhua, who had just arrived, was shaking hands cordially with Wu Youxiang, with an expression that showed they regretted not meeting each other earlier.

He laughed and joked:
"How come I've only been gone for a while, but it feels like I've been gone for a month."

"Haha, it's true that we met too late. Professor Hu even wants to stay." Wu Youxiang said.

Hu Xuhua pretended to decline and said:
"Hey, no, no, I was just joking."

“There is still a lot of research to be done in the factory.”

"If I stay, that place will definitely be affected."

His mouth was full of rejection.

But his eyes clearly said - hurry up, hurry up.

Wu Youxiang advised:
"It won't matter for a while. Besides, we can call other people over."

"Didn't you say that if we could get help from Consultant Li, it would be of great benefit to our research?"

"You can come back after you solve the theoretical problems, or even consider conducting research here directly."

After he finished speaking.

Hu Xuhua pretended to be hesitant and said:
"If that's the case, then it's not impossible."

The two sang together.

Seeing that Li Mu hadn't spoken yet.

Things are almost settled.

Fortunately, Hu Xuhua finally did not forget that this matter depended on Li Mu.

So he quickly signaled Wu Youxiang with his eyes.

The latter quickly asked: "What do you think?"

"Director, this is no small matter. Not to mention a team coming, even if Professor Hu comes, it will be troublesome." Li Mu said, who was played but didn't notice any clues.

As one of the leaders in the research of submarine-launched D bombs.

He is also the chief designer of Type 033 and Type 033A submarines.

Hu Xuhua's transfer is very sensitive.

And it is not easy to get the Baltic Shipyard to release the people.

Hearing his words, both Wu Youxiang and Hu Xuhua looked disappointed.

But then, Li Mu said:
"But some of the early research work can be done in Kyoto."

“It’s just that there can’t be too many people coming.”

"At most a few key persons in charge will come, and some people must stay there as well."

He just finished speaking.

Hu Xuhua's face instantly showed a deep joy, and he said:

"No problem, all up to you, just let us come over."

"In that case, I will apply to the higher-ups right away and have their people come over as soon as possible." Wu Youxiang said happily.

Seeing this, Li Mu thought for a moment and said:

"Let me go and talk to him. I have a good relationship with the director of the Baltic Shipyard."

"That's fine. You won't offend anyone if you go, but I may not." Wu Youxiang did not insist.

After all, this kind of "poaching" is still quite hateful.

Although Hu Xuhua and others will definitely have to go back in the end.

But who can say for sure about this matter?

……

Afterwards, after it was agreed that Hu Xuhua and others would come to Kyoto.

Li Mucai asked about the research progress.

Seeing that they were talking about confidential content, Wu Youxiang left on his own accord and even called for security soldiers to stand guard at the door.

Hu Xuhua first talked about the situation of anechoic tiles and anechoic coatings, saying:
"The development of the anechoic tiles went smoothly. However, we encountered some problems with the anechoic coating."

"Based on your proposal, we have established two research directions: rubber-based noise-absorbing coatings and polyurethane-based noise-absorbing coatings."

"The former has lower technical costs, is suitable for large-area coating, and has good water resistance and corrosion resistance..."

He told the whole story in detail.

In fact, there is Li Mu’s plan guidance.

The research and development progress there is still very good.

Although there are some minor difficulties from time to time.

But it does not affect the overall progress.

Li Mu waited until Hu Xuhua finished speaking before saying:

"I won't say much about the rubber-based sound-absorbing paint. You should be able to solve it yourself if you give me some time."

"I will mainly talk about polyurethane-based sound-absorbing coatings. According to my theoretical inference, it should have seven difficulties."

"Optimization of sound absorption performance, water resistance and corrosion resistance, mechanical properties and durability, environmental practicality, construction technology, safety and cost..."

He first summarized the basic situation.

Then start analyzing them one by one.

The problem of optimizing sound absorption performance.

It mainly refers to the need for polyurethane materials to have good sound absorption performance in a wide frequency range, especially at low frequencies.

And the sound absorption performance is closely related to parameters such as material density, porosity, and elastic modulus, making it difficult to meet all requirements.

To solve these two problems.

First, it is necessary to optimize the acoustic properties of the material by adjusting the formula of polyurethane, such as adding fillers, foaming agents, etc.

The second step is to design a multi-layer structure.

The acoustic impedance matching of different layers is used to enhance the broadband sound absorption effect.

The last step is to introduce nanomaterials or microsphere structures to improve the sacrificial properties of the materials.

But this is not easy to do, and it depends on whether the Materials Research Institute can make any breakthroughs in scanning tunneling microscopy.

But even if you don’t, it doesn’t matter.

After solving the difficulties in the other 6 aspects.

The anechoic coating obtained is enough to deal with the radars of Emperor M and Big Brother.

At least within 5 years.

Neither of the two great powers could possibly catch up.

At medium and long distances, their submarines are basically undetectable.

Theoretically, it can only be detected when it is close to 10 kilometers or even several kilometers.

But this distance.

It's already a direct attack on their faces, enough to scare Emperor M and Big Brother half to death.

……

It took 1 hour.

Li Mu gave the follow-up research direction for anechoic tiles and anechoic coatings.

There is a follow-up supplementary plan.

There shouldn't be any major problems in developing the two.

After he finishes speaking.

Hu Xuhua put down the paper and pen and breathed a sigh of relief.

When Li Mu opened his mouth.

He habitually took out his notebook and wrote down everything.

After all, anechoic tiles and anechoic coatings will eventually be used on nuclear submarines, so they must be taken seriously.

As the chief designer of Type 033 and Type 033A, his original life goal.

It is to design an atomic submarine that is powerful enough to compete with the M Empire and Big Brother.

But after meeting Li Mu.

He felt that "sufficient to compete" could be changed to "completely crush".

To achieve this goal, we must strive for excellence.

Li Mu watched Hu Xuhua studying with his notes and did not urge him.

Until it raised its head again.

He then said:
"Professor Hu, I will write a letter for you to take back later."

"After all, you are all the backbone of the factory."

"Even if I come forward, I have to inform Director Ding first."

Hear this.

Hu Xuhua, who had been unable to suppress a smile on his face, now looked bitter.

He rubbed his hands embarrassedly and said:

"Advisor Li, you don't know that when I came out, I only told the factory director and didn't even wait for his consent."

If I go back.

Let’s not talk about the final result for now.

Ding Xiuxun would definitely scold him first.

"Don't worry, if Director Ding really didn't want you to come, he would have stopped you halfway." Li Mu said with a smile.

Hu Xuhua thought about it carefully and it seemed to make sense.

He hesitated and said, "Okay."

"That's settled then. I have other things to do, so I'll leave first. I'll ask my secretary to pass the letter to you later. If you want to walk around the institute, you can find Director Wu." Li Mu said.

After saying that, he stood up and prepared to leave.

Hu Xuhua did not doubt it when he heard it. After all, it was normal for Li Mu to be busy.

Just wait until Li Mu leaves.

He realized belatedly that something was wrong and thought:

"The factory manager wanted me to come, so it doesn't seem to conflict with him scolding me or not!"

……

The other end.

Big Brother Embassy.

Alexei walked quickly through the door.

Not in yet.

He heard someone calling him.

When he turned around, it was Bauman, a professor who worked at the same school as him.

The latter greeted with a smile:
"Professor Alexei, long time no see!"

"Long time no see, Professor Bauman. You just arrived in Xia Country. Don't you want to take a rest?" Alexei said.

He rushed here because the domestic expert group had arrived.

Bauman sighed:
"We can't rest. The higher-ups have given us an order to confirm the authenticity of the mechanical dog as soon as possible."

"If this kind of weapon can be developed, the impact on war will be enormous."

"Now that our struggle for supremacy with Emperor M has reached a stalemate, we urgently need such high-tech military weapons to break the deadlock."

Hear this.

Alexey was about to say something.

Then Yakov quickly walked out of the door and said:

"Let's talk inside, don't discuss it here."

Hearing this, Alexei and Bauman immediately stopped talking and followed him into the embassy.
