Wandering Spaceship in Deep Space Chapter 87: Uneasy feeling

　　 Zhang Yuan nodded, indicating that he could understand.

　　 Even a lazy person like Li Zhendong has become hurried during this period, wanting to make some achievements.

　　 When I first boarded the spacecraft, although I felt the pain of parting, I also had a sense of anticipation and freshness for the future.

　　 But now, this sense of expectation has slowly passed away, the pace of life in the spacecraft has become faster and faster, and there are obviously fewer people chatting on the roadside.

　　 Because everyone knows clearly that this is in the desolate and deserted universe, and this mothership is everyone's all.

　　 This sense of security is seriously inadequate.

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

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

　　 Humans, small and fragile creatures. If an ordinary person is naked in the universe without a spacesuit, his life will not exceed 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.

　　 In the next 15 seconds, the person will fall into a coma, and it is up to fate to survive.

　　Because everyone knows these common senses, as the home planet moves away, a strong sense of anxiety can involuntarily arise.

　　Even Zhang Yuan himself has such a sense of uneasiness. He often convulsed in his dreams, woke up, and found that he had just had a nightmare and fell asleep again.

　　 So Zhang Yuan's entertainment gossip turned into a life-saving straw, and he was talked about. Because people want to deliberately create a relaxed environment similar to the earth in their intense work to comfort their fearful subconscious.

　　 Such subconscious changes are normal, and there are some psychologists in the spacecraft who are specifically responsible for this aspect of control. Large-scale group activities are often held in various communities, not only to increase group awareness, but also to treat cosmophobia.

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

　　"So, to find a life partner, it is best to find a more beautiful girlfriend. Two people can also complain to each other, and one can only resist. Unless you have a particularly good psychological quality... "

　　 here again, here again.

　　 Zhang Yuan hurriedly turned his head, just as he hadn't heard.

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

　　 Zhang Yuan nodded. Brother Zhao is indeed a very good instructor. Even in the case of very poor experimental conditions, it is always possible to make recommendations that fit the timing very well.

　　 From this aspect, he is more qualified than Academician Ding. Until now, except for the regular meeting at the beginning of each month, Zhang Yuan has not seen Ding Zhaodong several times... Even if he saw it, he couldn't say a few words.

　　 In the next few minutes, he hurriedly came to the side engine observation room, where there were bright display screens, and many staff members were focusing on the parameter changes.

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

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

　　 looked at the second screen again, which showed the plasma turbulence in the reactor. Under extremely high brightness, even if it was specially processed, it was still a bit dazzling.

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

　　"Hi, Zhang Yuan!"

　　 "Hi, hello." I greeted several colleagues, and no one paid any attention to him. Zhang Yuan studied these screens on his own.

The high temperature produced by 　　 nuclear fusion will vaporize the sodium metal in the furnace wall. These hot sodium vapors can do external work and generate electricity.

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

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

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

　　 After fusion of a helium-3 nucleus and a deuteron nucleus, a helium-4, a proton and a huge amount of energy are produced. Because it does not produce neutrons, it is cleaner and more stable than deuterium-tritium fusion, and the maintenance cost is also lower.

　　 However, mining helium-3 on the moon is actually a big flicker in aviation engineering. Because the abundance of helium-3 in the lunar soil is too low, and the cost of mining is too huge, if you count it, 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 ~ IndoMTL.com~ Even if the helium-3 is ignored, the moon still has great development value.

　　 It wasn't until the Jupiter base at the back was developed and the second-generation nuclear engineering helium-3 fusion was truly popularized.

　　"What you see now is the flow image of plasma turbulence, how beautiful! The control software in it was designed by your father 30 years ago using the general method of wavelet transform, 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 transform..." Hearing his father's name, Zhang Yuan was very proud.

　　"In essence, the problem of plasma turbulence has not been completely solved yet."

　　John Wilson is a high-tech talent specializing in plasma physics. He has been lamenting that human technology is too poor, naive, and so on.

　　 However, he is actually a very simple person.

　　 "Isn't the restraint very good now? The current method is quite stable. In theory, there will be no accidents for dozens or hundreds of years." Hearing John questioning his father's achievements, Zhang Yuan was a little unconvinced.

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

　　John Wilson said with certainty: "If only 10 T magnetic fields are used for restraint, I can guarantee that these high-temperature plasmas will still splash on the furnace wall and stop the entire device!"

　　The magnetic field intensity used by humans is 100T, which is 10 times larger.

　　 Coupled with the fact that supercomputers constantly monitor these plasma turbulences, and use super-powerful computing power to maintain the balance of turbulence, it is no wonder that it is called a typical miracle of great power.
