Institute of Aeronautical Materials, a large experimental room in the rear base.

Wang Hao stood in front of the experimental operation table, stared at a small ball of powdery objects on the table, and asked, "This is the extracted granular material?" ”

"Yes."

Cao Dongming nodded, "There are many others over there, but they are all large particles, and they are not shaped, we subsequently separated, and only got this small pile of materials, which was determined to be a semi-topological particle morphology with microscopic observation." ”

Wang Hao nodded lightly.

Yang Yunhe pointed to the mixer on the operating table and couldn't wait to introduce, "Academician Wang, look at this again, the mixer designed by our team." ”

"In this study, the agitator played a huge role. We made three improvements in a row and did many experiments to determine that this form can separate granular materials. ”

Wang Hao followed and looked over.

The agitator is a metal pillar with a complex fan blade design around it, which can be understood as the sawtooth of the wall breaker to some extent.

Qu Gui also said, "Our several experiments are mainly for the stirrer, and there is nothing else to adjust. ”

"We all think that the shape of the agitator is the breaking point."

"Experiments have proven that this is indeed the case."

Yang Yunhe is also very happy to be affirmed, because the stirrer is the research done by his team, and it can play a role in the experiment, which is his achievement and credit.

Wang Hao walked over to take a closer look, touched a few fan blades with his hand, nodded and commented, "It's amazing!" ”

Yang Yunhe was immediately excited.

Although he is much older than Wang Hao, the academic influence of the two sides is not at the same level at all, and it is also worth being happy to be affirmed by Wang Hao.

Both are academicians.

But the gap between academicians and academicians is very large, even incredibly large.

Some academicians are known for their research and are considered to have made significant contributions, while others are simply unknown and most of their research is not recognized.

Yang Yunhe belongs to the latter, his research field is metal processing, precision machining, is biased towards engineering, most of the results are also niche.

In addition, high-end manufacturing and precision machining are a big field.

There is a lot of research in the direction of large fields, and his research is just adding bricks, some breakthroughs can improve the technical level, but some are highly substitutable, and it is difficult to say how much of the improvement will be.

Yang Yunhe has always hoped that he can have more outstanding results.

Now it's it.

The research of micron-scale particulate materials is very important, and the agitator developed by his team has helped the manufacturing technology of new granular materials to achieve a breakthrough from 0 to 1.

Next, they continued to tell Wang Hao about the experimental process.

Yang Yunhe also kept saying, "Now that the first step has been taken, the next step is to slowly study and continuously improve." ”

"A new manufacturing technology is to be slowly improved."

"The most important thing is that we have made it, which shows that this path is the way to go......"

The others could only nod their heads.

Wang Hao just smiled when he heard it, he didn't care what Tang Yunhe said, he just continued to understand the experimental plan, various participations and experimental results.

After most of it was understood, he was silent for a while and said, "Well, you can do another experiment in the afternoon, starting with material cutting and continuing with manufacturing." ”

"I'm going to take a look at the whole process......"

This request came as a surprise.

Yang Yunhe said in surprise, "Academician Wang, if it starts from material cutting to production, it will take at least three days. ”

"Three days is three days."

Wang Hao didn't care, "I was prepared before I came, and I will stay in the capital for at least half a month this time, and I will go to the science and technology department next Monday." ”

"Okay."

Yang Yunhe and Cao Dongming glanced at each other, and immediately summoned the others to prepare for the experiment.

This time it's a repeat of the previous experiment.

They had already done many experiments in a row, and the preparation for the experiment was relatively simple, and by the afternoon, the experiment had officially begun.

The first step is to cut the material.

This part is in charge of Yang Yun and his team, and several manufacturing processes are required to cut the material to achieve faster dissolution at high temperatures.

At the same time, the equipment is debugged to ensure that a special environment corresponding to voltage, magnetic field and temperature can be created.

During the whole experiment, Wang Hao stayed in the operation room, carefully checked each step, and asked if he didn't understand well.

This allows for a detailed understanding of the entire manufacturing process.

By the afternoon of the third day, the experiment was over, and they had succeeded in making a granular material in a container, but after cooling, they only got a small amount of powdered material, most of which was still glued together, or had no form at all.

"Only a handful have succeeded in separation."

"We think the main reason is still on the stirring bar." "We talked about making the fan blades denser, and doubling the speed of the central shaft, maybe we could get more powder particles." ”

Wang Hao nodded, "It's really related to the stirring stick." ”

"But I don't think it's about making the blades more dense, it's about reducing the number of blades, and the speed of the central axis is also decreasing." ”

"Reduced quantity? Lower? ”

Yang Yunhe was puzzled.

Cao Dongming and Qu Gui also did not understand, and they also believed that the small number of powdered particles was caused by 'insufficient stirring'.

If you increase the number of blades and increase the speed of the central shaft, you can get more powdered material.

Wang Hao said, "I watched the whole experimental process, I watched every process, and there was no problem on the whole, but in the end there were very few powder particles." ”

"So the problem must be with the final agitator process."

"The superconducting metal solution is no problem, and the intensity of the stirring is high enough. So have you thought of a possibility, maybe it's not that the stirring is not sufficient, but that the stirring is too sufficient. ”

"The powder particles that have been separated are re-bonded together with more adequate agitation......

He pointed to a large mass of metal stuck together, and said, "If you look at this mass of metal, you can see that it is made up of small particles. ”

"Most of the small particles have a semi-topological structure."

Speaking of which, that's enough.

Yang Yunhe, Cao Dongming, and Qu Gui all looked at the mass of metal, Qu Gui simply walked over and put the metal under the equipment, and used the amplifier of the equipment to observe.

This is a direct magnification observation, the magnification is not so high, but it can still be seen that the metal is indeed composed of individual particles.

Yang Yunhe also went over to take a look, and he was a little reluctant to believe it.

What Wang Hao denied was his judgment.

If Wang Hao's statement was correct, it proved that his judgment was wrong, and he couldn't help but whisper, "Maybe it's not a semi-topological particle?" ”

; "A lot of the materials look like this when you zoom in......"

There is also truth to this statement.

However, Cao Dongming and Qu Gui were more willing to believe Wang Hao, and they could observe the specific situation and draw conclusions, they immediately asked others to do a slice study of the lump of metal, as long as they were placed under more sophisticated equipment to observe, they could know what the shape of the tiny particles was.

After the actual sectioning observation, the experimenters also made a zoomed-in picture showing the morphology of a dozen tiny particles.

It's obvious.

Wang Hao is right.

"These are the semi-topological particles, which means that we have separated them, but the stirring force is too high, and they are glued together." Cao Dongming concluded.

Wang Hao said, "This is also related to the magnetic field. ”

"Your magnetic field design is oriented in both directions, and I think you can try to use a vertical circular magnetic field layout so that the direction of the magnetic field is consistent with the direction of the stirring."

"That way, the small particles don't stick together easily."

Wang Hao made another suggestion.

This time, Yang Yunhe didn't speak, because the results had proven him wrong, but he was still very active in the experiment, and immediately worked with the rest of the team to remove the fan blades, and also modified the stirring vessel.

Cao Dongming found others to transform the magnetic field generator together.

Although it is not possible to quickly turn the magnetic field into a perfect circular layout, it is still no problem to control the whole in the direction of stirring.

A day later, the study group conducted a second trial.

This time, there was no need for any preliminary preparations, they used the existing materials to directly do the final step of research, poured the melted established materials into the container containing the superconducting metal liquid, and opened the central stirring device with the external closure.

With a 'buzzing' sound, the stirring only lasted for about twenty seconds before stopping.

After that, it enters the cooling and extraction process.

By the time we got to this point, everyone knew that the experiment had been successful, because they could clearly see a large pile of powder particles, not the substances that were glued together.

Wang Hao couldn't help but smile.

Although it is not possible to determine the results and the exact size of the manufactured granular materials, even large particles of about 100 microns can greatly improve the annihilation force field technology based on metal materials.

These include lateral anti-gravity technology, conventional anti-gravity technology, and F-ray generation technology, which is directly related to controlled nuclear fusion technology.

The biggest difficulty in controlled nuclear fusion technology lies in the reaction vessel.

Whether it is a tokamak magnetic field device or a combination of other theoretical studies, the ultimate goal is to create a vessel that can accommodate high-strength reactions.

Today's micron-sized granular materials can increase the strength of the DC anti-gravity field and the strong annihilation force field of the outer layer.

The anti-gravity field of the inner layer can reduce the reaction rate.

The high strength of the strong annihilation force field in the outer layer and the high upper limit of the maximum energy that can be absorbed means that the reaction strength value that the container can hold is higher.

This guarantees security and stability.

After the end of the experiment, Wang Hao also praised, "The research has finally made great progress, everyone has done a good job, this research is too important." ”

"I don't have to keep it a secret from you."

"The day after tomorrow, I will go to the science and technology department to talk about nuclear fusion technology, and with the progress of granular materials, the foundation of nuclear fusion research will be more stable......"

“……”

What Wang Hao said is still very shocking.

Cao Dongming and Qu Gui were very excited, they knew that research was very important, but they only knew that it was related to the annihilation force field before.

Outcome......

What is at stake in controlled nuclear fusion?

Yang Yunhe was also very excited, but he couldn't laugh a little, and felt that he had been hit very hard.

Before, he always felt that his research was very powerful, helping the research of granular materials to achieve a breakthrough from 0~1.

But if you think about it carefully, their research is based on Wang Hao's theory, even if the breakthrough from 0~1 is achieved, it is also completed together, and the research of the agitator is just a small difficulty.

Wang Hao came to the Institute of Aeronautical Materials, and it only took a week to make great progress in their research, which can be said to have achieved a breakthrough from 1~100.

This gap ......

It doesn't feel reasonable!

……

Wang Hao went to the science and technology department to talk about nuclear fusion technology.

Decision-makers in the science and technology sector and other institutions want to know Wang's views on nuclear fusion research, because nuclear fusion is such a major research that it is not easy to even make up your mind to do it.

Wang Hao's views are crucial.

Previously, Wang Hao was not interested in the research of nuclear fusion, mainly because there was not enough foundation, and there were too many technical difficulties to overcome to start a project to do large-scale engineering research, and it was extremely difficult to truly manufacture a controllable nuclear fusion device.

Now it's different.

Wang Hao believes that there is a certain foundation, and the research on nuclear fusion can also be discussed and put on the agenda.

That's what he said in the tech department.

Apparently.

Wang Hao's personal influence is very large, and his views even play a decisive role.

When he returned to Xihai from the capital, the science and technology department had already released the news in advance, and some media began to report on it in advance.

"Centennial Project: The Flower Grower Prepares to Start a Nuclear Fusion Research Project!" 》

Nuclear Fusion, Super Project! 》

"The Flower Planter will be the first country to master controlled nuclear fusion technology!" 》

"China may start the project within a year......

A series of reports are 'chasing after the wind', and there is no substantial evidence, but there is a good saying: there is no wind and no waves.

When many media reported together, they must have heard some rumors, and public opinion also launched a heated discussion, most of which were supportive.

Ordinary people just praise it, and the focus is on the reaction of the academic community.

The academic community did not go into much detail about the news, and many experts came forward to say that "it is unlikely that nuclear fusion research will start in the short term." ”

"That's a super project, at least 100 billion yuan in scale."

"Even with the use of new technologies, the effectiveness is questionable, and there is no room for error in the research of nuclear fusion, and there should not be enough basic support at this time."

"Maybe it's just a discussion......"

The last statement has been recognized by many people.

There are a lot of big projects that are just in the discussion stage and not really implemented, the most obvious example is the Large Particle Collider.

For many years, the construction of the world's largest particle collider has been discussed, and the project has been demonstrated again and again, but the result is only discussion but no implementation.

Today's nuclear fusion research is less reliable than the Large Particle Collider.

It was definitely a bigger project than the collider, and it was a research project that did not have enough foundation, from entering the demonstration stage, to officially starting the project, and then to the research results......

How long does the time span take?
