The Planet's Life-and-Death Crisis

Principle According to Einstein's mass-energy equation E=mc2, when atomic nuclei undergo fusion, part of the mass is converted into energy and released. Only a small amount of mass can be converted into a large amount of energy. When two hydrogen nuclei collide, they can form a nucleus and release energy. This is a fusion reaction. The energy released in this reaction is called fusion energy. Fusion energy is another important way to utilize nuclear energy. The most important fusion reactions are: In the formula, D is a deuterium nucleus (heavy hydrogen), and T is a tritium nucleus (superheavy hydrogen). The total effect of the above two sets of reactions is: That is, every time 6 deuteron nuclei are "burned", a total of 43.24 MeV energy is released, which is equivalent to the average release of 3.6 MeV per nucleon. It is 4 times higher than the average 200/236=0.85MeV emitted by each nucleon in the n+ fission reaction. Therefore, fusion energy is a more powerful form of nuclear energy than fission energy. For fusion to occur between atomic nuclei, they must be brought close to the femtometer level. To achieve this distance, the nucleus must have a large kinetic energy to overcome the huge repulsion between charges. In order for the nuclei to have sufficient kinetic energy, they must be heated to very high temperatures (above several million degrees Celsius). Therefore, nuclear fusion reactions are also called thermonuclear reactions. The high temperature generated by the explosion of an atomic bomb can cause a thermonuclear reaction, which is how hydrogen bombs explode. Controlled nuclear fusion is a reaction in which plasma nuclei fuse a large number of nuclei in a controlled manner at high temperatures, releasing energy at the same time. Deuterium is the most important fusion fuel, and the ocean is a potential source of deuterium. Once controlled nuclear fusion using deuterium as the basic fuel can be achieved, people will have almost inexhaustible energy. A large amount of fusion energy is released by the explosion of a hydrogen bomb, and a large amount of fusion energy is released by an atomic bomb explosion. Nuclear power technology nuclear power technology The large amount of fission energy that comes is uncontrollable. Just over a decade after the first atomic bomb exploded, people found ways to control the fission reaction and built fission power stations. It was originally thought that a fusion power station could be built after a hydrogen bomb exploded, but it was not that simple. Even fusion reactions can occur under earth conditions: 3H+2H—→4He+10n+1.76×10^7EV It can only occur in large quantities under conditions of extremely high temperatures (>4000 0000°C) and a sufficiently high probability of collision. Therefore, a controlled thermonuclear fusion reaction that can actually be used as an energy source must not only generate and heat plasma to a high temperature of hundreds of millions of degrees Celsius, but also effectively restrain this high-temperature plasma. This is the problem that has been studied in recent decades and the goal that is expected to be overcome. In China, the Institute of Physics of the Chinese Academy of Sciences, the Institute of Plasma Physics of the Chinese Academy of Sciences, and the Southwest Institute of Physics have done a lot of work in experimental engineering and theoretical research, and have made many important progresses.

I don't know why, but when I read the introduction, I felt like I was writing about the dark forest of the Three-Body Problem.

Great book, please read it!

It was all booked yesterday, but there are so few fans. Maybe I got some free coins, so I might as well just give it a small reward. 😄

I recommend a hard science fiction book called "Under Deep Space", which talks about the destruction of the earth and the survival of mankind on the moon...

Inexplicable entry... Inexplicable content... Inexplicable exit...

What kind of stuff is written here, and I also said that I would like you to read the space articles written by others before you talk about it, okay?

After reading more than 30 chapters, I really can't stand it anymore. The writing at the beginning is still very good, but after meeting the aliens, it becomes less good. Especially the dialogue between pig feet and aliens is a bit childish 💔

In the crisis-ridden slaughterhouse of the universe, the strong are like hunters holding butcher knives, and planets and civilizations are like meat on a butcher's chopping board. What Yang Yi is about to witness and face is not only the fall of planets and the destruction of civilizations, but also the ubiquitous enemies in the multidimensional dark universe. Let's see how Yang Yi, an ordinary astronaut, grows up in countless battles and eventually becomes the powerful master of the ultimate civilization in the multidimensional universe. "The Tribulation of Life and Death on the Planet": A masterpiece of new elements, good articles and books, Mr. Talent, reward and support!

What do you think of Yang Yi? Do you think your personality is a bit boring, a typical science and engineering man? In fact, I also want to make the male protagonist lively and cute, and cheer for Yang Yi together 🙂
