Deep Space Fleet

Academician Ding continued: "I don't have 'hard work' and 'discipline' in my dictionary, only 'interest' and 'a sense of accomplishment'. Therefore, I do not limit your working hours and working days per week, the pressure of learning and The motivation comes from your own inner driving force ... if you have any questions, you can ask me directly, or you can ask your brother. "

After a pause, he asked again, "Well, what kind of research do you want to do? The space industry is just a major, and there are many subdivision directions. It is impossible to learn everything you want to learn. Over here. "

Zhang Yuan thought for a while and thought for a while, it was a little dazed at one and a half. He was interested in every direction.

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

"Furthermore, the current laboratory conditions are too poor and there are very few resources. Any experiment needs to be queued up. I still recommend learning some basic knowledge, unless you have particularly good ideas, and then do projects, you can also use the computer To do some simulation experiments, I can help you with this ... "

Now gravity is simulated by centrifugal force. For some more detailed experiments, Coriolis force is a nightmare at any point.

Academician Yuan Ding nodded, "That's true. Zhao Qingfeng, when you are free, you take him to the non-gravity area outside. Well ... just practice for a while in the nuclear fusion engine room."

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

As soon as Zhang Yuan's heart moved, he ran to the non-gravity zone outside for an internship. He was definitely willing.

The Earth Age's nuclear fusion engine is at the forefront.

"That's right." Academician Ding said, "If you want to graduate formally, you must at least publish an article in a journal of the Earth. Our new civilization's current thesis evaluation system has not been established, so we can only follow Or to be generally recognized by experts in the industry. "

Only one paper ...

I seem to see Zhang Yuan's doubts. Academician Ding said with a smile: "You don't think it is very simple. If it were not for the poor laboratory conditions here, my requirements would be higher."

Zhang Yuan came up with a sudden idea and suddenly asked: "What if I can't publish a dissertation?"

Academician Yuan Ding laughed: "Either apply for withdrawal or keep postponing graduation, and be the first group of people who die on the sky!"

Uh ...

Academician Pu Ding is actually very busy.

尽管 Although the "Earth Age" has been tested for a long time, there are still many small problems exposed during the entire voyage. Some things need to be adjusted temporarily, so these big men will not see a figure all day long.

In the next time, Zhang Yuan and his brother Zhao Qingfeng made more contact.

Zhao Qingfeng is an 18-level job and is responsible for the maintenance of the material circulation system. In fact, it is very busy, but the level of busyness is definitely lower than Academician Ding, at least every day.

原来 "That's the case, the work level is directly proportional to the busy level. My original second-level post was also a sweeping floor. You can absent yourself at will, this is not your job."

青 Zhao Qingfeng said with a smile: "No, I don't need to be in charge here all day long. It's just the initial stage of sailing, and there are only a few more temporary adjustment items."

"Go, I'll take you out to see!"

人员 Persons with a working level lower than level 10 who want to leave the living area must report to their superiors and must be accompanied by others.

"Passed, please be safe!"

One of the nurses and sisters suddenly smiled and said, "Mr. Zhang Yuan, please don't go out for more than 10 hours each time. Otherwise, you will lose too much calcium and easily become osteoporotic. You can go to the hospital and buy some calcium tablets.

好的 "Okay, thank you for your reminder."

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

哪里 "Where is it? I was fine ..."

Zhang Yuan's scalp was numb, and he hurried away.

The two put on their space suits and went up to the elevator.

The elevator slowly rises. As the line speed decreases, the “gravity” felt by Zhang Yuan is getting smaller and smaller. At the same time, a sense of vertigo standing in the "drum" of the washing machine was generated.

Finally, when the elevator reached the center axis of the spacecraft, all the vertigo disappeared, and the two were completely weightless.

The two men “swim” into a rail car with both hands and head to the air valve.

士兵 Several soldiers guarded the air pressure gates and saw Zhang Yuan. After checking their identities, they saluted.

滴 "Drop ~ Please be careful!"

Further out is the vacuum zone.

The track car slowly moved along the center axis to the first air pressure valve.

Huh! An exhaust sound ~ www.readwn.com ~ After the air in this small room was evacuated, it went to the second air pressure valve.

The entire pumping process was performed 3 times before the car successfully reached the outside vacuum zone.

The most precious thing in the universe is matter. Humans are not capable of creating a complete vacuum, so it is inevitable to lose a small amount of material every time they enter and exit.

Alas, as long as the lost material is within acceptable limits.

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 purpose is to reduce the mass of the spacecraft."

Brother Zhao nodded: "Yes, although the air density is low, but the total number is an incredible number ... If the mass of the spacecraft is as high as billions of tons, it is impossible to accelerate to seven thousandths of the speed of light. "If you think about it, the mass of our 500,000 people is only 30,000 tons, which is a difference of many orders of magnitude."

The interior of the cabin was empty, exuding dim lights. Brother Zhao's finger pointed out the window. "As for the complicated pipes, they are actually spacecraft cooling devices. The heat generated in the living area is brought to the outside by these condensation devices, and then radiated by the radiating sails of the spacecraft.

Don't look at the average temperature in space of more than two hundred degrees below zero, but there is no material exchange, the heat dissipation is ridiculously slow, and it can only be conducted by radiation.

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

Brother Zhao said slowly: "In fact, the current carrying capacity of our spacecraft is not enough to carry 500,000 people."

Zhang Yuan thought for a moment, they are half a million people, don't they live well?
