The Red Era, the Opening University Speech

Chapter 463 Four Large-Scale Complete Equipment
"Don't be nervous, just speak slowly." Li Mu comforted with a smile.

He didn't mean to "retaliate".

I just think that the other party can do this when the discussion is so intense.

I can also pay attention to notice his arrival.

Either you like to be distracted, or you still have some energy left.

And someone who can enter the Radar Research Institute cannot be someone who likes to be distracted.

So it must be the latter.

Hear this.

Zhang Guangyi slowly calmed down and recounted in detail everything that everyone had discussed just now.

The main problems are concentrated in three aspects.

First, there is the problem of weak technical foundation.

The core of the sonar system is the highly sensitive hydrophone.

At present, Xiaguo’s development in the field of precision acoustic sensors is almost entirely dependent on the assistance of its former big brother.

Our current independent research and development capabilities are not yet mature.

And if it weren't for the advances in high-performance computers and digital signal processing technology.

They also face issues with signal processing capabilities.

There are also underwater communications and power supply.

Deploying submarine cables requires materials that are corrosion-resistant and have high tensile strength.

Long-distance underwater power transmission technology also has major shortcomings and is greatly affected by the electrical conductivity of seawater.

Second, there are issues of marine environment and engineering challenges.

The water temperature conditions in the coastal waters of Xia State are complex.

Water temperature stratification, salinity changes and differences in seafloor topography can significantly affect the path of sound wave propagation, causing signal attenuation or distortion.

Busy fishing activities and natural noise can also drown out a submarine's signals.

Without advanced noise suppression technology.

I'm afraid they won't be able to detect the enemy's atomic submarine sound wave signals.

Another problem is that deployment and maintenance are extremely difficult.

Xiaguo's current ocean mapping capabilities are very limited, and the lack of accurate seabed topographic maps makes it difficult to select the best sensor deployment locations.

Underwater equipment needs to withstand high pressure, salt corrosion and biological adhesion for a long time, which also poses challenges in materials science.

The third and final question.

They also have big problems with funding and professional talent.

Although Xiaguo now makes a lot of money in the Western world by relying on the semiconductor industry and the gaming industry.

But a few billion dollars sounds like a lot.

When applied to national construction, it can only make a slightly bigger splash.

However, a huge project like the shore sonar array system would be difficult to complete without hundreds of millions or even billions of Xia country currency.

……

Following Zhang Guangyi's retelling.

The meeting room gradually became quieter.

Just different from before.

In this silence, one can faintly hear the anxious "boom, boom, boom~" sound of everyone's heartbeat.

A group of researchers looked at Zhang Guangyi and couldn't help but curse in their hearts:

"Why are you so honest?"

It's not just them.

Even Peng Shilu and Jiang Nanying were worried at this time.

After all, these words sound...

It's almost like saying that the shore sonar array system is no longer working.

If Li Mu was angry about this.

That would undoubtedly not be a good thing for the Radar Research Institute.

Just when everyone was getting uneasy.

Li Mu suddenly clapped his hands and said:

"That's right. It seems that everyone has really spent a lot of time discussing this in the past few days."

Hearing his words.

Everyone couldn't help but breathe a sigh of relief.

"Advisor Li, I actually think that there are many issues here that are still worth discussing and may not be unsolvable," said Peng Shilu.

Jiang Nanying on the side also hurriedly said:
"The director is right."

"Since you brought it up, you must have a plan."

“Others can’t solve it, but you must have a way!”

His tone was very determined.

The last sentence even sounds a bit offensive.

But no one present felt offended.

After all, this is indeed true.

Problems they can't solve.

The problem in front of me may not be unsolvable.

"Thank you for your praise, directors. I just have a rough preliminary plan to try. Whether it can be done or not, we still need to discuss it with everyone before making a decision." Li Mu said.

He didn't have the information.

He turned the Radar Research Institute into his own one-man show.

Research is never a one-person job.

It’s the joint efforts of everyone.

He continued:

"Let's first talk about the problem of high-sensitivity hydrophones."

"As a core component of the sonar system, it is key to capturing extremely faint underwater sounds."

"At present, our hydrophones are mainly MG-10, MG-20, etc., which were donated by Big Brother. They said that in terms of sensitivity..."

Li Mu didn't rush to get straight to the point.

Instead, we first analyzed their current development in this field.

In this regard, Xia State indeed relied on its big brother to establish a basic system.

However, these things have long been out of date.

If we slowly explore based on this, it will be difficult to catch up without a decade of laying the foundation.

Want to change this situation.

The only way is to get a high-sensitivity hydrophone.

After he proposed this idea.

Professor Zhang Lvqian below immediately raised his hand and asked:

"But Consultant Li, how should we study this?"

"Advanced piezoelectric materials, low-noise circuit design, multi-unit array design, beamforming technology, noise suppression algorithms and automatic filtering technology." Li Mu listed six directions in one breath.

Of course, besides that.

We can also make efforts in precision machining technology.

However, this improvement is not as great as the previous six.

After he finished speaking.

There was silence in the conference room.

Everyone frowned tightly, trying to find the right research path along these six directions.

Only half a day had passed.

No one can fully understand it quickly either.

finally.

They still gave up thinking.

Zhang Luqian raised his hand again and said:

"Advisor Li, please explain this to us in detail."

Hearing this, everyone in the conference room started to speak up, saying that they didn't understand.

no way.

If we keep going on, it will be dark.

Seeing this, Li Mu said:

"The piezoelectric material we use at present is mainly quartz. It has the characteristics of stability and low loss, which is suitable for the manufacture of acoustic wave sensors."

"However, it also has its own limitations. The piezoelectric coefficient is low, the sensitivity is limited, and the frequency range is narrow. It cannot detect weak sound sources and cover wide-band signals."

"So, my idea is to use artificial synthesis to create a new piezoelectric material - lead zirconate titanate."

After he finished speaking.

Someone responded immediately.

Compared with quartz, lead zirconate titanate does have great advantages.

Both the piezoelectric system and the frequency response range are far exceeded.

But there are also problems.

Although this material was invented in 54.

In Western countries, it is also widely used in the manufacture of high-performance sonar, ultrasonic sensors and piezoelectric transducers.

But I haven't heard of it being used in high-sensitivity hydrophones.

Of course, this is not the most critical thing.

The key is.

Xia State is completely blank in this regard.

"Do you already have the synthetic process for producing lead zirconate titanate?" Peng Shilu blurted out.

As soon as these words came out.

Everyone's eyes turned to Li Mu again.

Except for this reason.

They couldn't think of any other reason why Li Mu was so determined to carry out this research.

Li Mu nodded slightly and said:

“There is indeed a general process, but it still needs to be verified.”

"Its main raw materials are lead oxide, zirconium dioxide and titanium dioxide,"

"The process can be divided into seven steps: raw material preparation, mixing and masking, pre-firing, and molding..."

He briefly talked about the steps of the synthesis process.

Of course, more detailed information will require further experiments by others.

For example, dopants used to optimize material properties include antimony, manganese, iron and niobium.

There are also auxiliary raw materials: adhesives, grinding media and deionized water, etc.

Any step is missing.

Will affect the final result.

……

Experts and professors such as Zhang Luqian in the conference room returned to the familiar pattern.

Everyone quickly took out paper and pen and started taking notes.

Half an hour passed.

As Li Mu's last words fell.

They slowly raised their heads and looked at Li Mu again.

But in their eyes.

The look in his eyes has begun to change.

Questioning is questioning.

It's just that we don't want the country to waste hundreds of millions or even billions of funds and manpower.

If it's really possible.

Who wouldn’t want to build a shore-based sonar array system?

After having it.

In the near sea, Xia Kingdom will have great confidence when facing the nuclear submarines of Emperor M and Big Brother.

The strategic value here cannot be purchased by any amount of money.

Of course, there are still people who hold different opinions.

Chen Fangyun raised his hand and said:

"Advisor Li, with you here, I believe we will be able to overcome the technical difficulties and reach the foundation for building a shore sonar system."

“It’s just that I think we don’t need to rush into construction.”

"At this stage, it is a bit wasteful to spend so much money on construction. And we also lack the support of talents."

After he finished speaking.

Some experts and professors couldn't help but nodded.

This does make sense.

Xiaguo is indeed short of money.

And near the coast, they implement a near-shore defense policy.

Although constantly facing provocations from Emperor M and the transport captain.

But countries should not act on impulse.

It is certainly a good thing to eliminate their threats in the offshore areas.

But if the progress of scientific research in other fields is affected at the expense of the gains, it would be a loss.

Besides, they have no one yet.

Peng Shilu looked at Li Mu and said with a wry smile:
"Professor Chen is right. Let's not talk about the money issue. Even if the higher-ups are willing to allocate funds, we don't have the manpower!"

The research foundation of Xiaguo's scientific researchers in sonar systems is still built on the basic theoretical information provided by the big brother.

under these circumstances.

If we want to build such a large sonar array project, we definitely won’t have enough manpower.

Li Mu can't just shoulder and do everything by himself.

Even if he wants to.

I'm afraid the higher-ups won't agree.

Facing the questions raised by Peng Shilu and others.

Li Mu hesitated for a moment.

Technology has never been a problem for him.

We can also find a way to solve the money issue.

However, the talent issue is indeed difficult to change in a short period of time.

Talent education in Xia State is still in its infancy.

Although there are top leaders such as Qian Wushi, Guo Huai, and Hu Xuhua, the basic talents are still in a serious shortage and will remain so for a long time.

He thought for a moment, then said:

"First recruit a group of students and train them slowly."

"As for funding, I will discuss it with the higher-ups later."

"The shore-based sonar array system plays an important role for our country and we must develop it."

Hear his words.

Peng Shilu nodded and said:
"No problem, I'll report it right away!"

In fact, the above means almost the same thing.

I only let him propose it first because I was afraid of Li Mu’s opposition.

This way, even if it fails, there will be a buffer.

Watching Peng Shilu leave.

Li Mu did not delay, turned around and said:

"Let's continue."

……

I was busy until 10pm.

Li Mucai left the Radar Research Institute by car.

Go home.

He sat on the sofa and took a nap with his eyes closed.

In my mind, I was thinking about how to make money.

As a psychology major.

He could see that Peng Shilu seemed to be hiding something when he said those words.

Think about it carefully.

The reason behind it is not difficult to guess.

"I'm afraid the country is out of money again!" Li Mu sighed in his heart.

Xia Guo has indeed made a lot of money in the past two years.

But there are also many places to spend money.

Supercomputers, large oxygen top-blown converters, Xuanniao-1 general-purpose helicopters, 3-ton die-forging hydraulic presses, etc. are all major projects.

Although with his help, there was almost no technical R&D cost.

But even if the R&D costs are low.

The final construction will still require an investment of tens of millions or even hundreds of millions.

As a result, the little money left in the semiconductor and gaming industries is naturally not enough.

"Why not get some more heavy machinery to mine resources?" An idea suddenly popped up in Li Mu's mind.

But soon, he gave up decisively.

Producing a bunch of heavy machinery can indeed generate a lot of resource value in a short period of time.

But resources like these should be used less and less.

If the mining is too aggressive, we will be strangled by others when there is no more resources in the future.

Emperor M did an excellent job in this regard - he did not use his own things, but instead stole other people's things.

"Let's find a way to continue expanding the semiconductor industry." Li Muxin thought.

We want economic development to achieve explosive growth.

This is only possible if it is selling military weapons.

Otherwise you can only take it slowly.

Of course, you can also consider selling scientific research equipment.

Such as photolithography machine.

As long as they dare to put up a price and bid.

Even if the offer is 1 million dollars, Big Brother and Emperor M will probably be tempted.

After all, as far as he knew.

So far, only Emperor M has developed a computer with a computing speed of 100 million times per second.

At this level, the integration is estimated to be less than 5w.

They give 10 yuan, and Emperor M and Big Brother will pay for it.

……

The next day, early.

Wash up after exercise.

Li Mu continued to study the expansion of the semiconductor industry.

Just when he was studying seriously.

Guan Jianmin knocked gently on the door outside the study and whispered:

"President Guo and Leader Qiao are here."

Hear this.

Li Mu put down the pen in his hand, stood up and welcomed Guo Mo and Qiao Guanghua into the house.

Then he asked Guan Jianmin to make tea quickly.

While saying:

"Two leaders, come here, is there any action from the Ruidian Mission?"

"Rui Dian has indeed been asking to meet you, but this time it's not because of them." Guo Mo said.

Hearing this, Li Mu was slightly surprised.

But it’s right to think about it.

Without the Nobel Prize as an inducement, the other party would lose their legitimate reason to contact me.

Of course, whether he receives it or not.

Emperor M can use this to a certain extent to confirm his identity.

He continued:

"Could it be that Big Brother has made some new moves?"

"That's right. They sent a team of experts and asked to meet with you under the pretext of discussing the donation of scientific research equipment to us," Guo Mo said.

After he finished speaking, Qiao Guanghua on the side continued:
"Big Brother, my diplomat Yakov said that this matter was discussed with you. Is this true?"

This time things are really weird.

In the past, Big Brother even provided them with technical equipment.

They are basically obsolete products.

Unlike this time, they are willing to provide the most advanced scientific research equipment.

And it’s a gift!
"It's true, but there are conditions." Li Mu nodded slightly.

Then, he talked about his encounter with Yakov when he was giving a lecture at Beijing Institute of Technology.

Contact Alexey.

In their plan.

However, Guo Mo was a little surprised when he found out that Big Brother was going to provide an operating system for the robot dog.

He hesitated and said:

“This operating system won’t help them, right?”

The mechanical dog doesn't sound as powerful as space-based weapons.

But a combat unit that can be flexibly maneuverable on the battlefield and charge forward fearlessly.

Its value remains high.

"It certainly helps." Li Mu smiled, and then said, "But it also puts more constraints on them."

This sentence was a big breath.

Guo Mo and Qiao Guanghua were almost choked to death.

After all, Big Brother’s military strength is too strong.

If I take out the mechanical dog again.

That would undoubtedly be bad news for the neighboring Xia State.

"So you don't plan to write this operating system properly, or just delay?" Guo Mo asked.

Li Mu shook his head slightly and said with a smile:
"It's impossible not to accept something good that's delivered to your door."

"An operating system that can only be viewed but not used is exchanged for seven or eight advanced scientific research equipment."

"This deal is still a very good deal, but of course you have to be careful."

To make a robotic dog, you need more than just an operating system.

It also involves fields such as communication technology, electronic engineering and bionics.

"In that case, I will hold a meeting to discuss this matter when I get back," Guo Mo said.

Having said that, he stood up excitedly.

Seven or eight of Big Brother’s most advanced scientific research equipment!

It's impossible not to be jealous.

And there is Li Mu's guarantee.

There is no need to worry about the technology being mastered first.

"Don't be in a hurry, President Guo, I have another R&D project that I want to discuss with you." Li Mu stopped him.

Hearing this, Guo Mo paused and sat back on the sofa, curiously asking:

"What project?"

Now, the Chinese Academy of Sciences will basically execute the research files given by Li Mu.

Of course, the premise is that it is not like the shore sonar array system.

The cost is as high as tens of billions. One or two is okay, but more than that is indeed a bit difficult.

“辊宽700毫米20辊带钢轧机、直径80-200毫米钢管冷轧机和辊宽2800毫米热、冷轧铝板轧机，把他们搞出来！”李暮道。

Hear his words.

Guo Mo and Qiao Guanghua were both stunned.

It was as if what they heard was not a research project.

It's like the name of a dish.

Is research so easy?

Guo Mo took a deep breath and said:

"Building four large-scale complete equipment in one go? Isn't this a bit too hasty?"

"Since you brought it up, you must know that they have been developed a long time ago."

"It's just that our technological maturity, industrial chain support, industrial foundation, resources and talents are still insufficient. I'm afraid..."

He didn't finish his words.

But the meaning is obvious.

——It’s too expensive.

The four sets of large-scale equipment require an investment of at least 300 to 400 million yuan.

"Then just build a cheap one and then spread the news. The main purpose is to build momentum for Tiangong. He has been silent for too long." Li Mu said.

He knows the country's difficulties.

He will try to save as much as possible before solving his financial problems.

Hearing this, Guo Mo pondered for a moment, then said:
"You've made the right decision. Since we're going to let Tian Gong receive the award, we have to give him a new achievement."

"If it's a few million, it shouldn't be a big problem."

"Of course, I will try to get more for you later."

It is indeed impossible to do all four sets at the same time.

But one set is much better, at least the investment will be much lower.

And it's related to the "Star Wars" plan.

If Li Mu persists, the higher-ups might actually agree.

But you can't say this out loud.

"Three or four million will be enough. Let's start with a cold rolling mill for steel pipes with a diameter of 80-200 mm." Li Mu nodded.

The cost of this set is between 300-800w.

Because the preliminary development has been completed.

So the cost will be greatly reduced.

The main investments are in four areas: materials, manufacturing, supporting facilities and manpower.

It may take about 400w to complete the task.

"Okay, then I will go to Fengtian Heavy Machinery Plant and First Heavy Machinery Plant to transfer people over to cooperate with your research." Guo Mo said decisively.

Compared with 30 or 40 million, 30 or 40 million are much easier to accept.

According to the above standards, as long as the research project does not exceed 1000 million yuan, it does not need to be reported and the project can be started directly.

……

With Guo Mo's departure.

Li Mu talked to Qiao Guanghua again about the meeting with Big Brother's expert group.

After the time and place are determined, at the State Guesthouse the day after tomorrow.

Qiao Guanghua did not forget to remind:

"Those experts are obviously here for our technology, so we must be careful."

"If you feel you can't handle it, you don't have to say anything."

"But don't worry too much. Someone will accompany you to meet them."

He was worried that Li Mu was too young and would be misled by the expert group.

"Please rest assured, I know my limits. Besides, it's not a bad thing to reveal some information appropriately. Isn't it?" Li Mu said with a smile.

Hearing this, Qiao Guanghua was stunned for a moment, and then he thought about it and it seemed to make sense.

Strict prevention and control will certainly prevent the news from leaking.

But Emperor M and Big Brother can't find anything.

I'm afraid it's not that easy to fall into the pit.

……

After seeing off Qiao Guanghua.

Li Mu looked at the time and it was almost noon.

After thinking about it, he stood up and prepared to go to the Automotive Research Institute.

Since the last time.

It has been a few days now.

It's time to go over there and take a look at the situation.

He wasn't worried about the rest.

However, for the cannon-fired D bullets, some are still needed.

After all, powerful firepower will be the support for the Xuanwu-1 main battle heavy tank to be invincible on the battlefield.
