Get the Fishing Heaven System at the start

Ok.

To say nuclear gatherings, I am afraid to talk about it first - nuclear fission!

The raw materials used.

It is mainly from uranium 235, or 239.

These two elements isotope are both radioactive.

The decay will be completed within a short time.

This decay, or fissure, will make a large nuclear nucleus, become two small nuclear nuclei, while simultaneously, and release two to three neutrons, and a large amount of energy.

And these two to three neules, to hit other unstable large nucleus, and accelerate the process of fissure.

Once this reaction, the speed of more than a certain limit will be produced ... chain reaction!

In short, it is a series of uncontrollable, dramatically fission reactions.

Because, in this process, the neutron number is increased in an index type, which produces an effect similar to an avalanche.

This principle is the core of the atomic bomb.

At early stages.

caution!

It is the highest, the design concept of the atomic bomb is to calculate a quality, then get two and a half uranium blocks. When you wait until it is suitable, let them be two, exceeding the quality critical point, uncontrollable chain reaction It is realized, and it is the explosion of the atomic bomb.

Say.

It seems to be quite simple.

In fact, it is very difficult to realize this process!

Take a look at the movie "I born in the air".

That batch of scientists who have worked hard to work hard in the early days of Summer, and struggled for a few years, they really made it.

why?

Because, it is involved in some specific details, the key point is to study repeatedly, and scrutinize.

Take another one more.

You can see that in any of the middle school physics textbooks in Xia Guo, I learned that the basic knowledge of nuclear fusion can be learned, but I have to make an actual atomic bomb, and I am idiotic.

The actual situation.

Researchers who truly engage in nuclear physics research.

Summer will be more stringent and controlled to avoid accidents.

Length.

Say back.

Today's summer, nuclear power stations have many, the power generation mode taken is controllable nuclear fission.

That is, a chain reaction can be controlled.

What?

It is simple to control the quantity of neutron.

In the nuclear reactor of the nuclear power station, there is something called graphite bar, control rod, which can be used to reduce neutron, absorb neutron, so, the speed of chain reaction will become controllable.

In the reactor, there will be water flow.

After the water flow is heated, it can be used to generate electricity after the nucleation is heated.

There is a saying.

Nuclear power generation, efficiency is relatively high.

And compared to thermal power, it has to be more environmentally friendly.

of course.

The most environmentally friendly, it may have a hydropower, along with the new wind, solar power, just these, efficient is low, and the environment is closely related.

Without the terrain, it is unable to generate electricity.

The same, no wind, or rainy day, wind, solar energy, you have to have GG Smecta ~

Length.

Say back to the topic!

The nuclear fission has been speaking.

Then, let's talk about this nuclear fusion.

It is a hydrogen element, or hydrogen isotope, polymetis into a helium element.

Under the same quality.

The energy released by nuclear fusion is much higher than the fission.

How high is the specific?

If there is 10 grams of hydrogen or hydrazine, such a change, after the reaction, the energy released is probably equivalent to the standard coal of burning -200 ton!

Exquisite?

The principle and application of nuclear fusion.

In fact, people have already mastered, just unable to achieve this process.

Instead, it has been made ... more terrible hydrogen bomb than the original bullet!
