Zhang Yuan nodded, indicating that he could understand.

Even a lazy guy like Li Zhendong has become hasty during this period and wants to achieve something.

When I first got on the spaceship, although I felt the pain of parting, I also felt the expectation and freshness of the future.

But now, this sense of expectation is slowly passing, the pace of life in the spacecraft is getting faster and faster, and there are obviously fewer people chatting on the roadside.

Because everyone knows clearly that this is in the desolate and vast universe, and this mothership is everything to everyone.

This sense of security is seriously insufficient.

Although the "Earth Age" is huge and warm and comfortable, it still cannot be compared with the planet like the Earth that has stood for 4.6 billion years in the universe.

If a medium-sized meteorite hits it, it will completely destroy the spacecraft and no one can survive.

Humans, small and fragile creatures. If an ordinary person does not have a space suit and is exposed in the universe, his life will not exceed 90 seconds, the air in his lungs will completely escape from his body within a few seconds, and the remaining oxygen in the blood can last for about 15 seconds.

In the next 15 seconds, people will fall into a coma, and whether they can survive can only be left to fate.

It is precisely because everyone knows these common sense that as the mother star goes away, a strong sense of uneasiness is involuntarily developed.

Even Zhang Yuan himself felt this kind of uneasiness. He often cried in his dreams. When he woke up, he found that he had just had a nightmare and fell asleep in a drowsy way.

So, Zhang Yuan's little entertainment gossip became a life-saving straw and was talked about by others. Because people wanted to deliberately create a relaxed environment similar to the earth in their stressful work to comfort their fearful subconscious.

Such subconscious changes are normal. There are some psychological experts in the spacecraft who are specifically responsible for this control. Large-scale group activities are often held in various communities, not only to increase group awareness, but also to treat cosmic phobia.

But even so, dozens of patients with depression appeared in half a year.

"So, if you want to find a life partner, it's better to find a more beautiful girlfriend. Two people can complain to each other, and one person can only resist. Unless your psychological quality is particularly good..."

It's coming again, it's coming again.

Zhang Yuan quickly turned his head and pretended that he hadn't heard it.

"By the way, after the spacecraft turns successfully, the nuclear-powered engine will be turned off and will not be restarted after half a year. If there is any observation experiment, you only have one day today... Or, you can also visit the side engine."

Zhang Yuan nodded. Senior Brother Zhao is indeed a very good instructor. Even when the experimental conditions are very poor, he can always make suggestions that fit the timing.

In this regard, he is much more qualified than Academician Ding. So far, except for the regular meetings at the beginning of each month, Zhang Yuan has never seen Ding Zhaodong a few times... Even if he saw him, he couldn't say a few words.

In the next few minutes, he slowly came to the side engine observation room, where there were highlighted displays, and many staff members were focusing on the parameter changes.

From one of the display screens, you can see that a long plasma flame ejected from the flanks, causing the entire spacecraft to slowly rotate.

The angular velocity of the spacecraft rotates is very low, and it takes more than 20 hours to complete the 180-degree rotation, so everyone basically didn't notice it.

Looking at the second screen, it shows the plasma turbulence in the reactor. At extremely high brightness, even if it is specially treated, it is still a bit eye-catching.

This infrared map is like a complex vortex of water flow, and the transport of plasma across the magnetic field is mainly driven by low-frequency drift wave turbulence.

"Hi, Zhang Yuan!"

"Hi, hello." He greeted several colleagues, but no one came to pay attention to him. Zhang Yuan studied these screens on his own.

The high temperature generated by nuclear fusion will vaporize the metal sodium in the furnace wall. These scorching sodium steam can do work to the outside and generate electricity.

At the same time, plasma will be sprayed out as work fluid under the action of a magnetic field, providing kinetic energy to the spacecraft.

The principle is simple, but this nuclear engine device is the crystallization of human wisdom. It is so complex that every component, even the welding method, can write a paper!

It is also the second generation of nuclear fusion engine of human beings.

After a helium 3 nucleus and a deuteronucle fusion is fusion, a helium 4, a proton and huge energy are generated. Since no neutrons are produced, it is cleaner, stable, and has lower maintenance costs than deuterium and tritium fusion.

However, mining helium-3 on the moon is actually a big flaw in aviation engineering. Because the abundance of helium-3 in the lunar soil is too low, the cost of mining is too huge. After all, you will find that using helium-3 fusion is not as cost-effective as using the first generation of deuterium-tritium fusion.

However, it is not useless to establish a space base on the moon, because the moon is the most suitable natural base for space industry production. Even if the helium-3 is ignored, the moon still has great development value.

It was not until the Jupiter base was developed and the second generation of nuclear engineering helium-3 fusion was truly popularized.

"What you see now is a flow image of plasma turbulence, how beautiful! The control software in it was designed by your father using a common method of wavelet transformation thirty years ago, and it is also the best algorithm for humans at present."

In the observation room, a senior brother named John Wilson spoke.

"Is that true? The common method of wavelet transformation..." Zhang Yuan was very proud when he heard his father's name.

"But essentially, the plasma turbulence problem has not been completely solved yet."

John Wilson is a high-tech talent specializing in plasma physics. He laments that human technology is too poor, too naive, etc. all day long.

However, he is actually a very simple person.

"Isn't it very good to restrict now? The current method is quite stable. In theory, there will be no accidents in dozens or hundreds of years." Zhang Yuanluo was a little dissatisfied when he heard that John was questioning his father's achievements.

"Yes, it is indeed very stable. But in your ancient Xia language, it is really not wonderful to do miracles and use a very rough way to restrain these plasmas!"

John Wilson said with great certainty: "If only 10 t magnetic fields are used to constrain, I can guarantee that these high-temperature plasmas will still splash onto the furnace wall, causing the entire device to stop running!"

The magnetic field strength used by humans is now 100t, which is 10 times larger.
