The Red Era, the Opening University Speech

Chapter 219 What experiment did you do that is more important than the magnetohydrodynamic thruster?

After hearing his answer, everyone in the laboratory was surprised, and they looked at Li Mu with disbelief.

You are so young and not only are you good at theoretical research, but even your luck in experiments is so outrageous?
In material experiments, luck accounts for more than half of the success factors!

“I just used everyone’s previous experimental data and combined it with theory to deduce a number that I think is correct. I was also very lucky to be able to push the experiment forward.

"At the same time, without everyone's previous efforts, even if I was lucky, it wouldn't be so good that I could advance the experiment progress by blindly guessing." Li Mu said with a smile.

Peng Shilu said: "That's also very rare. Just based on these data, we can analyze the proportion of near success! Besides, luck is often the decisive factor in scientific research!"

"That's true. You have achieved such good results with only 198 times of data. If I give you 1,000 times, I think it is not impossible to achieve the same result in one step!" Deputy Director Jiang Nanying at the side began to praise.

Other experts and professors also joined in the praise and expressed admiration.

Li Mu said helplessly: "Director Peng, Director Jiang, you are too kind. I was just a little luckier."

He knew this would be the result.

Fortunately, it was just a one-time attack and would not arouse any suspicion, and it could also be attributed to good luck.

When it comes to scientific experiments, luck is sometimes really important.

Some people conducted experiments ten thousand or one hundred thousand times before they found the door to success, but some succeeded directly after only one hundred times. There is really no way to explain it with common sense.

……

Afterwards, because Li Mu's experimental samples performed extremely well, after recording the data he gave, Peng Shilu had people use instruments such as the Goue magnetic dessert and X-ray diffractometer to conduct further performance tests on the prepared magnetic fluid.

The final results, whether it is stability, magnetic properties, particle size distribution, or rheological properties, the data are all quite good.

This undoubtedly made everyone more excited, and they rolled up their sleeves and continued to work on the experiments.

He even wanted to invite Li Mu to join him, but of course he refused on the grounds of time constraints.

Someone inevitably asked: "Advisor Li, what experiment did you do that is more important than the magnetohydrodynamic propulsion device?"

Li Mu naturally couldn't explain, he could only smile and say nothing. When everyone saw this, they immediately understood.

"Okay, Consultant Li works part-time in several research institutes, so it's normal for him to be busy. We can't force him to do anything." Peng Shilu smoothed things over and then came out with him.

And said:

"I think there won't be any major problems in preparing the magnetic fluid. The next step is to prepare the three materials: electrodes, liquid helium, and liquid nitrogen."

"At present, the country mainly uses glass tube electrodes, and has also conducted some research on graphite electrodes."

"Graphite electrodes have good electrical conductivity, high temperature resistance and good thermal stability, making them an ideal electrode material. The disadvantage is that they are relatively expensive."

"We currently agree that we should study graphite electrodes and try to reduce costs while improving their performance. What do you think of this direction?"

After saying this, Peng Shilu suddenly felt a little regretful and felt that he should not have asked Li Mu.

In terms of electrode materials, graphite electrode is already the best choice.

Although Li Mu has done good theoretical research in applied physics, he probably only has some understanding of materials science, but not that much.

If you can't answer it, it will inevitably be a bit embarrassing.

But it was just a sudden thought that he thought Li Mu might have a better idea.

Thinking of this, he quickly said: "Actually..."

"Graphite electrodes are indeed good, but I think there are better options." Li Mu's words made Peng Shilu swallow back what he was about to say.

"What's the better choice?" he asked impatiently.

Li Mu hesitated for a moment, then said, "I think titanium can be used as the electrode material."

"Titanium? Its electrochemical properties are indeed good, but can it be used as an electrode material for magnetohydrodynamic thrusters?" Peng Shilu was stunned and asked in confusion.

Although titanium materials have been studied to a certain extent in China, only sponge titanium has been produced, which is mainly used to make industrial titanium alloys. No one has done any research on electrode materials.

Li Mu nodded slightly and said, "I think it is feasible. As long as the surface is modified and self-metallized, the titanium material can be given good conductive properties."

"Wait, don't be impatient!" Peng Shilu was shocked when he heard this, and then he ran back to the laboratory in a hurry, got a pen and a notebook, and continued: "Go on, speak slowly, I'll write it down."

His appearance attracted some experts and professors who were watching the experiment in the laboratory.

Seeing their director holding pens and notebooks in front of Li Mu like a student, everyone couldn't help but show surprise and gathered around him.

Li Mu didn't care about the crowd watching and said directly:

"In fact, surface modification metallization technology has been around for a long time, but we have never thought of applying it to titanium materials."

"My idea is to first improve the bonding ability, conductivity and brazing properties of titanium through steps such as electroplating, micro-arc oxidation and coloring."

"Then we will improve the wear resistance, corrosion resistance, thermal shock resistance and insulation properties of the titanium surface..."

……

He first briefly explained Protocol's ideas about conductive materials on the surface of titanium.

It sounds simple, but it's not that easy to experiment.

But this did not affect the excitement of Peng Shilu and others at all.

After listening, Peng Shilu immediately said: "I will go find experts and professors from the Materials Research Institute to verify it!"

After saying that, he said something to Li Mu and left in a hurry.

If the method is feasible, not only will the material problem of magnetohydrodynamic thrusters be solved, but our country's research on electrode materials will also take a big step forward!

Li Mu smiled and dealt with the curious questions from the experts and professors around him for a while. He did not stay long and soon continued to head to the Radar Research Institute.

Although the computer simulation platform has not yet been successful, this does not mean that the research at the Radar Research Institute cannot proceed at all.

It is obviously not enough for Professor Xu and Professor Lu alone to integrate the range gate circuit, single-sideband filter, main beam clutter suppression circuit and detection filter group.

Li Mu went to guide the structural design and ensure that there were no major problems. He then returned to the Semiconductor Research Institute to continue the design of the computer simulation platform and material calculation software.

Here, Peng Shilu took his notes and rushed to the Institute of Materials to find the director Zhou Ren. After telling him about the idea of ​​preparing titanium surface conductive materials through surface modification self-metallization technology, the latter's face changed slightly and he called a large number of experts in the institute to hold a meeting to discuss.

After an overnight data analysis and theoretical deduction, the final conclusion was - it is completely feasible!
Peng Shilu, with bloodshot eyes, heard the result and without even taking a break, he continued to go to the Chinese Academy of Sciences to find Guo Mo.

When Guo Mo heard Li Mu's idea of ​​preparing electrode materials that are more suitable than graphite electrodes, he agreed without hesitation to Peng Shilu's proposal for joint research between the Institute of Atomic Power and the Institute of Materials.

Now that we have decided to develop magnetohydrodynamic propulsion, we must do our best in every aspect.

In the past, they studied nuclear-powered submarines powered by traditional mechanical structures. Even if they were successful, they were still behind the M Empire and Big Brother. At most, they made them a little afraid, but it was still far from being a deterrent.

But the emergence of magnetohydrodynamic thrusters makes deterrence possible.

So what they have to do is to make this deterrent possibility a reality!

……

Semiconductor Research Institute.

As soon as it was light, Li Mu rode his bicycle to the gate.

Just as I was about to go in, I suddenly saw a few middle-aged men carrying briefcases and looking exhausted walking towards me. Two of them looked quite familiar.

But I couldn't remember where I had seen it.

He shook his head, no longer struggling, and was about to walk in when he suddenly heard an argument with the guards from behind: "We...are in a hurry...letter of introduction..."

He turned around and vaguely heard the content of the argument. It seemed that these people forgot to bring their identification documents, so they were stopped outside the door.

With the current security level of the Semiconductor Research Institute, people without credentials would not be able to enter, and would probably be arrested directly if they even approached.

The five people were able to stand there safely thanks to the leader who brought his ID, but it was obviously not enough for him alone.

At this moment, seeing that the guards could not be persuaded, one of the five people seemed to have seen Li Mu and suddenly shouted, "Advisor Li, Advisor Li, do you remember me? We met at the J Language Conference!"

Hearing this, Li Mu took another look and remembered that, except for the middle-aged man in the lead, he had met the other four at the J language conference.

"But why are they here, and they look so tired?" Li Mu was a little confused.

Is he here to support computer simulation platforms and material calculation software? That doesn't make sense, he just applied yesterday.

Without time to think clearly, he stepped forward, called the guard, and said: "This is Professor Su from Henan, Professor Wu from Shanghai, and Professor Zhang from Sandong... I will vouch for them, let them in."

When the guard saw that it was Li Mu, he felt a little embarrassed but still let the five people in.

When the middle-aged man in charge saw that the five people were brought in, he first breathed a sigh of relief, and then thanked Li Mu.

After the conversation, Li Mu was surprised to find that these four professors had actually received orders to come to the Semiconductor Research Institute to support research.

"I'll go get the letter of introduction for them now. Consultant Li, I'll leave them in your care." After the leading middle-aged man said this, he hurried away again.

The remaining four professors looked at Li Mu and greeted him one after another:

"Advisor Li, long time no see. I didn't expect that we would have the opportunity to do research together."

"Yes, I haven't completely mastered the J language you created yet, and I have many questions I would like to ask you."

"I also have many ideas about the application of J language. We must communicate with each other if we have the chance."

……

As the four of them spoke, they all placed Li Mu on an equal footing with themselves.

As the creator of the J language, this achievement alone is enough to surpass most people in the field of computer technology in the country, not to mention Li Mu's age, which is incredibly young.

"Okay, of course I can if there's a chance." Li Mu accepted everyone's invitation with a smile, and then said, "But before that, we still have to complete the task first."

After hearing his words, several people's faces became serious and they stopped chatting.

Professor Su from Henan thought for a moment and asked, "We still don't know what research project we want to support. Consultant Li, you should know, right?"

"Just follow me and you'll understand." Li Mu didn't rush to explain, but took them directly to the computer room.

Along the way, many researchers from the Semiconductor Research Institute greeted him enthusiastically, and he responded with a smile.

This treatment made the four professors behind him look a little strange.

……

Arriving at the computer room, Li Mu first greeted Huang Kun, who was leading people to build the template code for the computer simulation platform.

Seeing him coming with people, Huang Kun first signaled everyone to continue the analysis, and then he trotted over and asked, "Why, have you come up with any good ideas? Can you speed up our research?"

"I don't have any good ideas, but with the addition of four professors, the research speed will definitely be greatly improved." Li Mu said with a smile.

After that, he introduced the identities of the four people.

Huang Kun was delighted when he heard this and said, "I didn't expect it to be so fast. After only one day, the people supporting the research have arrived."

"I didn't expect that either." Li Mu smiled, and then continued: "But fast is a good thing. The current research and development is very tight, and we must hurry up."

"Then I won't waste any more time talking. Tell them about some research projects on computer simulation platforms and start the research right away!"

"Okay, several professors, follow me. Consultant Li, you can come too. I can report to you on the current progress." Huang Kun said immediately.

Afterwards, he led the four people into the computer room and began to introduce:
"The computer simulation platform is a visual simulation tool based on supercomputing research, which is used for simulation design in multiple fields, including communication, control, signal processing, etc...."

"At present, our research plan is quite clear. The construction of the computer simulation platform is divided into 74 modules, namely continuous modules, discrete modules, functions and platform modules..."

"At present, the frameworks of each module have been built by us. You and those who arrive later are responsible for completing the content construction of these modules as soon as possible!"

Huang Kun spoke very quickly, but none of the four professors complained.

From his introduction and the researchers busy coming and going in the computer room, they could see that this was an extremely difficult and critical research project.

After being assigned the task, they didn't care that they had just got off the train, and immediately expressed their desire to start working.

The task was urgent, so Li Mu did not bother to be polite with them. He agreed straightforwardly and personally led them to adapt to the rhythm of research and development as quickly as possible.
