Zhang Yuan nodded, indicating that he understood.

Even a lazy person like Li Zhendong has become in a hurry during this time and wants to make some achievements.

When I first got on the spaceship, although there was the pain of parting, there was also a sense of anticipation and freshness for the future.

But now, that sense of anticipation has slowly passed, the pace of life inside the ship has become faster, and there are significantly fewer people chatting on the roadside.

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

This sense of security is seriously inadequate.

Although the Earth Age is large, warm and comfortable, it is still not comparable to the Earth, a planet that has stood in the universe for 4.6 billion years.

A medium-sized meteorite, if it collides, can completely destroy the ship, and no one will survive.

Humans, small and fragile creatures. An ordinary person, without a spacesuit, naked in the universe, will live no more than 90 seconds, the air in the lungs will completely escape the body in a few seconds, and the residual oxygen in the blood can last for about 15 seconds.

After another 15 seconds, the person will fall into a coma, and whether he will survive or not will have to be left to fate.

Because everyone is aware of these common senses, as the home planet moves away, I can't help but feel a strong sense of unease.

Even Zhang Yuan himself had such a sense of uneasiness, he often had convulsions in his dreams, and when he woke up, he found that he had just had a nightmare and fell asleep groggily.

As a result, Zhang Yuan's little entertainment gossip became a lifesaver and was talked about. Because people want to deliberately create a relaxed environment similar to the earth in the midst of intense work, to comfort their subconscious of fear.

Such subconscious changes are normal, and there are some psychologists in the spaceship, who are responsible for this aspect of control. Large group events are often held within each community, not only to increase the sense of community, but also to treat cosmic phobia.

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

"So, if you want to find a life partner, it's best to find a beautiful girlfriend, and the two of them can complain to each other, and one person can only resist. Unless you're particularly mentally good......"

Here we go again, here we go again.

Zhang Yuan hurriedly turned his head, pretending not to hear.

"By the way, after the spacecraft turns successfully, the nuclear power engine will be turned off, and it will be turned back on after half a year. If there are any observational experiments, you only have one day left today...... Alternatively, you can take a tour of the side engine. ”

Zhang Yuan nodded, Senior Brother Zhao is indeed a very good instructor. Even when the experimental conditions are very poor, it is always possible to make a proposal that is very well timed.

In this respect, he is much more qualified than Academician Ding, and until now, except for the regular meeting at the beginning of each month, Zhang Yuan has not seen Ding Zhaodong a few times...... Even if I saw it, I couldn't say a few words.

For the next few minutes, he walked unhurriedly to the side-facing engine observation room, where there were bright displays and many staff members were focusing on the parameter changes.

From one of the displays, long plasma flames can be seen erupting from the flanks, causing the entire ship to slowly spin.

The angular velocity of the spacecraft rotation is very low, and it takes more than 20 hours to complete a 180-degree rotation, so everyone is basically unnoticed.

Looking at the second screen, it shows the plasma turbulence in the reactor, and at the very high brightness, even if it has been specially treated, it is still a bit dazzling.

This infrared spectrum resembles a complex vortex of water currents, and the transport of plasma across the magnetic field is mainly driven by the turbulence of low-frequency drifting waves.

"Hi, Zhang Yuan!"

"Hi, hello." I said hello to a few colleagues, but no one paid attention to him. Zhang Yuan studied the screens on his own.

The high temperature produced by nuclear fusion vaporizes the metal sodium in the furnace wall, and these hot sodium vapors can do work externally to produce electricity.

At the same time, the plasma will be ejected as a working medium under the action of a magnetic field to provide kinetic energy for the spacecraft.

The principle is simple, but this nuclear engine device is the crystallization of the highest human intelligence. It's so complex that every single component, even the way it's welded, can be written in a paper!

It is also the second generation of nuclear fusion engines of mankind.

The fusion of a helium-3 nucleus with a deuterium nucleus produces a helium-4, a proton and a huge amount of energy, which is cleaner, more stable and less expensive to maintain than deuterium-tritium fusion because it does not produce neutrons.

However, mining helium-3 on the moon is actually a big blunder in aeronautical engineering. Because the abundance of helium-3 in the lunar soil is too low, the cost of mining is too huge, and it will be found 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 build a space base on the Moon, since the Moon is the most suitable natural base for the production of the space industry. Even if the helium-3 in it is ignored, the moon still has great development value.

It wasn't until the later Jupiter base was developed that the second generation of nuclear engineering helium-3 fusion was truly popularized.

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

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

"Really? The general method of wavelet transformation ...... "Hearing his father's name, Zhang Yuan was very proud in his heart.

"But in essence, the problem of plasma turbulence has not been completely solved until now."

John Wilson, a high-tech talent specializing in plasma physics, lamented all day long that human technology was too poor, too naïve, and so on.

However, he is actually a very simple person.

"Isn't it good to be restrained now? The current method is quite stable, and theoretically speaking, there will be no accidents for tens or hundreds of years. Hearing that John was questioning his father's achievements, Zhang Yuan was a little unconvinced.

"Yes, it's stable. But in your ancient Xia language, it is a miracle to vigorously restrain these plasmas in a very rough way, which is really not wonderful! ”

John Wilson is very affirmative: "If only 10 T's of magnetic field were used to confine, I can guarantee that the hot plasma would still splash onto the furnace wall and stop the whole plant!" ”

The strength of the magnetic field used by humans today is 100 T, which is 10 times larger.

Coupled with the fact that the supercomputer monitors these plasma turbulence at all times, and uses super computing power to maintain the balance of the turbulence, it is no wonder that it is called a typical example of a miracle of force.
