Wandering Spaceship in Deep Space Chapter 77: Gravity-free zone

Academician 　　 Ding continued: "There is no'endure' and'discipline' in my dictionary, only'interest' and'sense of accomplishment'. Therefore, I do not limit your daily working hours and the number of working days per week. The pressure and motivation comes from your own inner driving force... If you have any questions, you can directly ask me, or you can ask your brother."

　　 paused for a moment, and he asked again: "By the way, what kind of research do you want to do? The space industry is just a big major, and there are many subdivisions in it. You want to learn everything, yes It’s impossible to learn."

　　 Zhang Yuan thought about it seriously for a while, and was a little at a loss for a while, he was quite interested in every direction.

　　While he was thinking, Senior Brother Zhao suddenly said: "If you don't have a particularly complete understanding of the entire space industry, you can first see and see on the spacecraft, and then consider the direction. It is always right to lay a good foundation." /

　　" Moreover, the current laboratory conditions are too bad and resources are scarce. Any experiment needs to be queued. I still recommend learning more basic knowledge, unless you have a particularly good idea, and then go to the project. You can do some immersive experiments on the computer, I can help you handle this..."

　　The current gravity is simulated by centrifugal force. For some more delicate experiments, any Coriolis force is a nightmare.

　　Academician Ding nodded, "That's right. Zhao Qingfeng, when you have time, you take him to the outer weight-free area for a stroll. Hmm...just do some practice in the nuclear fusion engine room. Time."

　　"The nuclear fusion engine is by far the most complicated project. If you figure out the entire workflow, you can basically graduate."

　　 Zhang Yuan's heart moved, and he ran to the outer weight-free area for an internship. He must be willing.

　　The nuclear fusion engine of the Earth Age is the most cutting-edge thing.

　　 "That's right." Academician Ding said again: "If you want to officially graduate, you have to publish an article in a journal on the earth at least. The current thesis evaluation system of our new civilization has not yet been established, so we can only According to the calculations on the earth, or universally recognized by experts in the industry."

　　 Just one essay...

　　 seems to have seen Zhang Yuan’s question, Academician Ding said with a smile: “Don’t think it’s simple. If it weren’t for the poor laboratory conditions, my requirements would be even higher.”

　　 Zhang Yuan thought on a whim, and suddenly came up with a question: "If I can't publish the paper, what should I do?"

Academician 　　 Ding laughed: "Either apply for dropout, or postpone graduation, and be the first people to die on the stars!"

　　……

Academician 　　 Ding is actually very busy.

　　 Although the "Earth Age" has been tested for a long time, there are still many minor problems exposed during the whole voyage, and some things need to be adjusted temporarily, so these big guys never see a person all day long. .

　　 In the following time, Zhang Yuan and his senior brother Zhao Qingfeng, on the contrary, had more contact with each other.

　　 Zhao Qingfeng is an eighteenth-level job, responsible for the maintenance of the material circulation system. He is actually very busy, but the level of busyness is definitely lower than that of Academician Ding, at least every day.

　　 "It turns out that the level of work is directly proportional to the level of busyness. My original second-level position is a sweeper. You can absent from work at will, you won’t work."

　　 Zhao Qingfeng said with a smile: "No, I don’t need to manage it all day long. It’s just the beginning of the voyage, and there are more temporary adjustments."

　　 "Go, I'll take you out to see!"

　　 Persons with a work level of less than 10, who want to leave the living area, must report to their superiors and must be accompanied by other people.

　　"Verified, please pay attention to safety!"

　　 One of the nurse sisters suddenly smiled and said: "Mr. Zhang Yuan, please do not spend more than 10 hours each time you go out. Otherwise, too much calcium will be lost and osteoporosis will be easy. You can go to the hospital to buy some calcium tablets. ."

　　 "Okay, thank you for your reminder."

　　Another nurse laughed and said: "Wang Shuo, why are you serving such a good attitude today? Do you like him very much?"

　　 "Where can I find it? I'm already fine..."

　　 Zhang Yuan's scalp is numb, so he drives off quickly.

　　 The two put on spacesuits and walked into the elevator.

　　 The elevator rises slowly, and as the linear velocity decreases, the "gravity" that Zhang Yuan feels is getting smaller and smaller. At the same time, a feeling of vertigo standing in the "drum" of the washing machine was created.

　　 Finally, when the elevator reached the center axis of the spacecraft, all the dizziness disappeared, and the two of them were in a state of weightlessness.

　　 The two "swim" into a rail car with both hands and head to the air pressure door.

　　 There were several soldiers guarding these air pressure doors. They saw Zhang Yuan and the two of them. After checking their identities, they saluted them.

　　"Dip~Please be careful!"

　　 Further outside is the vacuum area.

　　The rail car slowly moved along the central axis to the first air pressure door.

　　哧! A sound of suction ~ IndoMTL.com ~ After the air in this small room is evacuated cleanly, it goes to the second air pressure door.

　　 The entire process of pumping was carried out 3 times before the car successfully reached the outer vacuum zone.

　　 The most precious thing in the universe is matter. Human beings have no ability to create a complete vacuum, so it is inevitable that a small amount of material will be lost every time they go in and out.

　　 However, as long as the lost material is within the acceptable range.

　　 Along the way, Zhao Qingfeng kept introducing various facilities and equipment in non-gravity areas.

　　 "Do you know why there is no air in the gravity-free zone?"

　　 Zhang Yuan thought for a while: "The main reason is to reduce the mass of the spacecraft."

　　 Senior Brother Zhao nodded: "Yes, although the air density is low, it adds up to an incredible number... If the mass of the spacecraft is as high as several billion tons, it is impossible to accelerate to a thousandth of the speed of light. The seventh. Think about it, the total quality of our 500,000 people is only 30,000 tons, which is many orders of magnitude difference."

　　 The interior of the cabin was very empty, exuding dim lights. Brother Zhao pointed his finger out the window, "As for the complicated pipes, they are actually the heat dissipation devices of the spacecraft. The heat generated in the living area is carried outside through these condensation devices, and then circulated through the radiant sails on the outer surface of the spacecraft to dissipate heat."

　　 Don’t look at the average temperature of space is more than 200 degrees below zero, but there is no material exchange, and the heat dissipation is ridiculously slow. The heat can only be dissipated by radiation.

　　As an important part of the ecosystem, heat dissipation can be said to be the top priority of the spacecraft.

　　 Senior Brother Zhao said slowly: "Actually, with the current carrying capacity of our spacecraft, it is not enough to carry 500,000 people."

　　 Zhang Yuan was taken aback. They are half a million people, are they not living well?
