Comprehension Against The Sky, Graduation Project Nantianmen Project!

Pantao Lab was in full swing.

domestic.

There are two laboratories have a similar news almost at the same time:

Controlled nuclear fusion has made a breakthrough!

Among them, the team led by Academician Qin.

In the "Oriental Super Ring" ignition device of the Tokamak device, the energy gain of controllable nuclear fusion was realized for the first time!

That is, the ratio of output energy to input energy (Q value) is greater than 1!

And the running time reached 101 seconds!

As soon as the news came out.

The whole world was shocked.

You know, power generation is realized with magnetic confinement nuclear fusion technology.

The key depends on the progress of two dimensions:

One is runtime.

The second is the Q value.

The two factors reinforce each other.

The difficulty of increasing the running time is:

Heated plasma doesn't always behave as it's supposed to.

There is always a lot of plasma that loses heat during the reaction.

None of the existing devices can last more than 100 seconds!

The difficulty of increasing the Q value is:

To increase the Q value, a stronger magnetic field or a larger device is required.

The cost of the device is positively related to the volume of the device.

Building larger installations requires overcoming more engineering problems.

And the cost is high and the cycle is long.

This time, Academician Qin's team made new progress.

The first realization of the Q value greater than 1 by human beings is the most attention-grabbing and exciting part.

It has given a shot in the arm to international controllable nuclear fusion research.

Just when many people feel elated.

soon.

A different voice came out.

Some "public enemies" and "experts" in China poured cold water on this:

"Achieving controllable nuclear fusion is far away!"

"Only in the context of energy and power generation, it makes sense to calculate the Q value."

"In the direction of magnetic confinement nuclear fusion, which has more potential to realize clean energy."

"Humans have not crossed the critical point where the Q value is greater than 1."

The implication is——

Although this result is worth gratifying.

But there's no need to be so happy.

Follow closely.

The media of Eagle Country and Eagle Sauce began to hype:

"The experimental purpose of the Huaxia ignition device is not to provide human beings with energy solutions."

"It's doing research on nuclear weapons!"

At the same time, some scientists of Eagle Sauce also jumped out and said:

"On clean nuclear deterrence and nuclear weapons, it doesn't matter if Q is greater than 1."

"What matters is being able to do more damage with less cost."

"And then there's the stability and repeatability of the whole process."

In general.

It is to cool down the voice of international concern about controllable nuclear fusion.

tell them--

Even for the study of nuclear weapons, a Q value greater than 1 has no practical significance.

Ever since.

Huaxia has made a breakthrough in the research of controllable nuclear fusion.

It turned out to be so weird that it turned into a "joke"!

in this case.

Two other laboratories research electric propulsion.

The statement said that a breakthrough has been made in the research of the Hall thruster.

It also became less concerned.

Because many netizens read it.

Thrust is only 4.5N from before.

It becomes 45N.

Straightforwardly, this kind of thrust makes no sense at all.

And began to say eccentrically:

"With this time and investment, it is better to quickly research the domestic engine!"

"I feel ashamed to use someone else's engine on my own plane!"

However!

Just under this sound.

The Department of Commerce and the General Administration of Customs suddenly promulgated a "Notice on the Implementation of Export Control of Xenon, Krypton, Zinc, Gallium, Germanium and Other Related Items"!

for a while.

Many people at home and abroad are confused.

The two rare gases xenon and krypton are relatively easy to say.

Although rare.

But it's not very useful right now.

The main point is that it is very useful in aerospace electric propulsion.

After regulation.

Although the international prices of xenon and krypton have risen slightly.

But it doesn't seem so obvious.

But the two metals gallium and germanium are different!

Because of these two rare metals, Huaxia has more than 80% of the world's reserves of gallium and germanium!

More importantly, gallium and germanium are important materials in the semiconductor industry!

So soon!

Because of this Export Control Notice.

The international prices of gallium and germanium began to soar instantly.

at the same time.

Stocks in the semiconductor industry, however, began to decline.

With this rise and fall, the lung tubes of Yingjiang and other Western countries suddenly started to hurt!

As a result, some cynical voices began to appear on the Internet:

"It is enough to control rare gases such as xenon and krypton. After all, electric propulsion has made progress."

"But why should gallium and germanium be regulated?"

"If you do this, won't you be afraid that there will be no computer or mobile phone to play with?"

For these doubts and ridicule.

Huaxia's official voice is very consistent:

"Perhaps we will soon have a breakthrough in the field of semiconductors."

Rabbits may behave suddenly.

It made Western countries a little confused for a while.

However, they will certainly not be completely indifferent.

Soon, some sanctions were introduced.
