CC, the fastest update material empire!

The iron-based superconducting research of tranquility, benefited from the investment in Qinhai, and the progress was very rapid. The results were published in the international top publication, making her famous gangs and even more than their mentor Chen Zong. then.

In two months ago, when the tranquility and Qin Haitong call, the new type of material that had been found above 77K has been discovered, but the preparation method is still not mature, and it is not possible for the time being.

Once the preparation method of this new material has made breakthroughs, the research of superconducting motors will usher in a new stage of thriving.

77K is the boundary of the liquid nitrogen temperature zone. The critical temperature is higher than 77K, which means that such materials can produce superconducting properties with liquid nitrogen as a coolant.

The cost of cooling with liquid nitrogen is very low, and it has strong operability in reality. In the case where the room temperature superconductor has not yet been introduced, the liquid nitrogen temperature zone superconducting is the goal of the engineers.

"The problem of the super-guided coil, we hope that your brother is.

Zhou Lin Lei said, I heard that the girlfriend in Qinhai is a supercodent expert. Zhou Lin Lei has been a lot of evaluation of Qin Hai, and it has been in the age of 50, which is actually coming to Qin Hai.

"In addition to the problem of the coil, the permanent magnet material is also a big problem. Now the maximum number of NdFe Boron is tall, but the temperature of the Curie is too low, the temperature of the working environment is slightly higher, and the magnetic property disappears. This is not enough for the motor we need.

Zhou Lin Lei immediately put forward the second question.

Qin Hai smiled and said that he himself and said: "This problem, Zhou Mong has to send me.

"you?"

Zhou Lin Lei is very different, "How, Xiao Qin is magnetically mated?"

"I have no major, all kinds of materials have been exposed.

Qin Haidao.

"However, we now make a new permanent magnet material, is based on ruthenium.

The magnetic strength is higher than that of NdFeB, and the Curie temperature can reach 600 degrees Celsius or more.

Does wear it not enough? "

"Curie temperature reaches a new permanent magnet material of 600 degrees Celsius?"

Zhou Lin Lei asked in surprise, "How did I have heard it?"

"This ... may be because we work too busy, don't pay attention to the relevant literature? Our material has been released for a long time.

Qin Hai said.

Zhou Lin Lei took his head and said: "Yes, I have been pondering the steam bulk problem, I have not paid attention to the information of magnetic materials and superconducting materials, I can't think of technology development. It's so fast, what is this ... "

Say here.

He suddenly waited, and he looked at the beginning of Yuguang in the eyes of the eyes.

I have been listening to them for their dialogue, and I naturally look in the eyes for Zhou Lin Lei's little action.

He huh, I asked: "Why, I know so, have you to stick to your original idea?"

"It can only be said that there are some reasons more than the original ideas, but the obstacle is still very large.

Zhou Lin Lei replied to the old man.

"Why don't you talk to Xiao Qin? You see, just you have to go, I told you to stay, you are still not happy.

How is the result, don't regret it, chat with Xiao Qin? "

I asked.

"Which is not happy ..."

Zhou Linlei's face is slightly red, just that he really thinks that it is a waste of time with Qinhai chat.

I have gone such an important information between I can't think of a few words. I know so, he will not reveal the meaning of you to leave.

Now I have revealed the old bottom, he is naturally quite embarrassing.

"You tell your thoughts with Xiao Qin, maybe your problem, you can get resolved in Xiaoqin.

I will encourage Zhou Lin Lei again.

"okay.

Zhou Linlei hesitated for a moment, nodded to accept the suggestion of the first day, and he turned his head to Qinhai and said seriously: "Xiao Qin.

In fact, we have another idea outside of this idea in steam.

That is electromagnetic ejection, I don't know if you have heard? "

"Electromagnetic ejection?"

Qin Hai smiled.

"Of course I have heard.

So, what you just said, asked the instantaneous power, which is used for electromagnetic ejection? "

Electromagnetic ejection is another ejection method other than steam ejection, which is the use of electromagnetic forces to eject aircraft on the aircraft carrier.

Compared to steam ejection, the structure of the electromagnetic ejection is simpler, and does not require layup of complex pipes, and does not need to consider the storage and leakage of high temperature and high pressure steam.

In addition, the power of electromagnetic ejection is determined by the magnitude of the current, so it is more controllable than steam ejection, belonging to a more promising aircraft elastic mode.

However, the technical problems faced by electromagnetic ejection are much more complicated than steam.

First, to accelerate the aircraft than the aircraft than the aircraft than the stationary state to the takeoff speed, which is extremely high for the power requirements of the motor.

Zhou Lin Lei just said to Qin Hai, a motor that requires a very high instantaneous power, refers to a motor for driving the ejector.

Two larger bottlenecks developed such motors are capable of supporting high-power coils and a strong magnet capable of operating at high temperatures.

In addition to the motor, the power supply device is also a big problem.

If the ejector is working on land, it is naturally possible to access a line of 100,000 yuan or higher voltage to provide powerful energy in a very short period of time.

However, in the aircraft carrier, it is very difficult to find such high-power supply equipment, even if the aircraft carrier, its generator is not likely to provide such high instantaneous energy.

It is possible to perform high power discharge in an instant, only one equipment, that is, a supercapacitor.

This capacity can reach thousands of Farased capacitors to store rich power and release them in a very short period of time.

Compared with people's daily rechargeable batteries, the super capacitors have several advantages: First, their storage capacity is stronger, the same weight supercapacitor stored power is several tens of times the charging battery; second, can support hundreds of thousands The repeated charge and discharge, and the ordinary charging battery will be scrapped in one or two thousand times; the third point is also the most important point, that is, the charging time and the discharge time are very short, this is precisely the electromagnetic ejector Most needed.

Zhou Lin Lei as a motor expert is arranged in the research of aircraft carrier, that is, because the military initial imagination is to use an electromagnetic dilometer.

However, after the existing technical reserves were fully inspected, Zhou Lin Lei had to regret to give up this idea and start to host the design of the steam ejection device.

I first knew that Zhou Lin Lei had never forgotten to electromagnetic ejaculation, lecture Zhou Lin Lei pushed this problem to the front of Qinhai.

"Super capacitance, superconducting, permanent magnet material, this is the biggest problem we face to develop electromagnetic ejection devices.

Zhou Lin Lei introduced the road to Qinhai.

"Sure enough, every item is a world-class problem.

Qin Hai sighed, Zhou Lin Lei's last name is "insulated gate bipolar transistor" in the last IGBT chip

It is a semiconductor component that performs power management in a high-power circuit, and is also a blank technology in China.

"Listening to Xiao Qin today, the superconducting research in our country has achieved breakthroughs, and the permanent magnet materials have a big breakthrough. This suddenly solves the two problems, it is really not easy.

Zhou Lin Lei said, "With such a speed, we can really have the difficulty of overcoming electromagnetic ejection within 20 years.

"20 years……"

Qin Hai is screaming, "Zhou Mong, you won't say jokes?"

"I really have this confidence.

Zhou Lin Lei said seriously.

"Hey ... I said, actually 20 years?"

Qin Hai is crying, Zhou Lin Lei is obviously what he meant, thinking that he thinks that 20 years is not enough to solve these problems.

In fact, Qinhai has some understanding of these technologies that Zhou Lin Lei said, know if there is enough capital investment, plus the correct research ideas, only five to ten years, it is enough to put these problems solved.

"Xiao Qin, don't look at these technical problems, several institutes in the electronics department are engaged in supercapacitance research, and there is no satisfactory progress so far.

As for IGBT, the difficulty is bigger ... "

Zhou Lin Lei explained.

When I first interrupted Zhou Lin Lei, he looked at Qinhai and asked: "Xiao Qin, you don't need 20 years, how many years do you think?"

The Qinhai face has a bitter laugh and says: "If I speel 19 years, I will not fan my ear scissors?"

"Of course you will fly!

In the beginning, I was a smile. "I know that you have potential for Xiao Qin, involving national defense construction, you are absolutely not to live.

"Most ..."

Qin Hai is in the heart, ready to say a 10-year period, to the mouth, suddenly saw the white hair in the early days, his heart, out of mouth: "Five years!

"Five years!

Zhou Lin Lei Teng stood up from the sofa, and got it before Qin Hai, staring at him, asked: "You said five years?"

"Yes, five years.

Qin Hai bite his teeth and promised.

The two technologies of super capacitors and IGBT have been expected to be expected for China at the time.

But after entering the 21st century, through the spring breeze developed by the high-speed rail technology, China's scientific and technological personnel achieved breakthroughs in five years, reaching the world's advanced level.

Qin Hai has aware of some key elements in these two technologies. He believes that if the Daqin Group can invest enough funds, it is entirely possible to study these two technologies in five years.

Of course, if you can give him more time, maybe in the investment in funds, it can also save greatly.
