Cyber ​​Heroes

Chapter 434: Centrifuges

Yuanwenren, Yuki and Liu Ri who followed also got out of the car one after another.

"Senior..." Liu Ri also wanted to imitate Pan Nike and rushed over.

But Xiang Shan's stick was on his shoulder: "Forgive me for the time being. I've made up my mind. I won't accept apprentices. It's useless if you pester me."

"Ah, senior, didn't I express my enthusiasm?" The former earth-drilling boy looked at Xiang Shan and said earnestly: "You have taught me martial arts right now, so it's reasonable to accept me by the way, right? ? Ah, I heard that there are indeed many knights who will go through multiple tests before accepting apprentices to judge their minds. Hero, you can't stop me!"

Xiang Shan withdrew his stick and shook his head: "So, I have taught you martial arts, is there any dissatisfaction with you? Why do you have to formally worship me as a teacher? You and Yuki learned from me together, right? Do you usually communicate with each other?"

Six nodded.

"I will teach you what I teach my apprentice. So what are you dissatisfied with? Why do you have to be my apprentice?"

Liu Ri said, "Do you need a reason?"

Xiang Shan was shocked: "Don't you need it?"

"Oh nameless hero, you will take me further into the rivers and lakes only if you become a master and apprentice!" Liu Ri showed the usual snarky attitude of teenagers, and said, "So you accept me as an apprentice?"

"I'm sorry, but I won't formally accept apprentices until I use my name again. So let's wait until that day."

The original hearer sighed, opened the six days, and used the text window to comfort him a few words.Then, Yuan Wencai said: "Senior, you haven't introduced yet. Who is this here?"

Although everyone absolutely believed in Xiang Shan, but unlike the two boys, Yuan Wenren still asked about Ai Tielang's identity.

"This one, Ai Tielang Ai Daxia, his alias is... hiss..."

Ai Tielang hurriedly said: "In front of the unknown hero, I dare not mention my little name."

Xiang Shan pointed at Yuan Wenren again: "This is my current partner, Yuan Wenren."

"'Keep the right gun'? I heard that you were ambushed by the government three years ago, and your activities have decreased. I thought you had..." Ai Tielang cupped his hands at the original hearer: "I have heard of you for a long time."

The original hearer also saluted: "The title of 'Lone Wolf Hammer' is much louder than mine."

Ai Tielang likes to use super-large caliber sniper rifles, and the guy he assassinates is like being hit by a battering ram, so he has this name.

The source of the news sent a document to Xiang Shan: "The results of this time have been written into a report. In addition, the high-level materials supported by the Earth Drilling Dragon of the Nephilim lineage have also been brought over."

Xiang Shan nodded.Different parts of the prosthesis have different requirements for materials.

Hardness, toughness, thermal conductivity, resistivity, and more.

Some parts also need to be mixed with pressure-sensitive materials to give a "tactile sense" and strengthen the warrior's ability to control the body.

These materials involve many different alloys.These alloys in turn require different metal elements.These metal elements are enriched in different regions.

It is easy to say if it is a job, but if a knight wants to get a top-notch prosthetic body, he must obtain extensive help.

Xiang Shan looked at Yuan Wenren's report, nodded and said, "Thank you, Xiao Yuan."

Xiang Shan thought for a while and asked, "Do you think the materials we have now can make a long-running gas separation device? I mean high-speed centrifuges and the like."

"Ah?" Yuan Wenren was stunned for a moment, "Well, let me ask, what do you need, senior..."

"Liquid helium, preferably with a little Helium III."

Yuan Wen said: "Senior, didn't you say that you don't plan to build a fusion furnace for the time being?"

"Of course it's not a fusion furnace." Xiang Shan shrugged, "The requirement for quantity is much smaller. I need refrigerant. Helium III mixed with ordinary helium IV will do."

Helium III is an excellent fusion fuel.Also, it doesn't release neutrons during the fusion process -- which would be much less disruptive to the instrument.Also, neutron radiation is relatively difficult to block.Because neutrons have no charge, they are difficult to confine with strong magnetic fields.

The reactor that releases neutrons is replaced with a reactor that does not release neutrons, and the protective materials used to slow down neutrons in the prosthesis can be removed, and a lot of things can be saved.

But the problem is that there is too little helium.

Helium is so light that it can easily escape Earth's gravitational pull.Since the birth of the earth, the helium here has been in a state of continuous escape.

And helium three needs beta decay to be born-generally speaking, this will be completed by natural reactions that occur in the interior of the earth.And these helium [-] will come near the surface during years of geological movement.Therefore, some underground gas mines will be mixed with quite rich helium three.

But at this stage, all known veins have been logged by the patrons.

Harvesting helium from seawater or air is very difficult.

But helium three is better than helium four as a refrigerant.

Using helium four as the working medium of the refrigerator can press the temperature to 2K, which is two degrees Celsius higher than absolute zero.

However, if the cost is not considered, if the refrigerant is replaced with helium III, it can continue to be reduced to less than 1K.

The earliest quantum logic gates, which could only operate near absolute zero, used this cooling technique.

Of course, Xiang Shan didn't use this one.The limit state of this quantum chip can work in an environment of 80K.

But "working" and "working well" are not the same thing.

Working in an ultra-low temperature environment can effectively reduce the interference of thermal noise.

Moreover, in an ultra-low temperature environment, helium can also have superfluidity, and can flow through extremely thin capillaries or slits without hindrance and loss.

Combined with high-strength capillary tubes, it can become an excellent auxiliary heat dissipation system.

For warriors, this is super useful.

The original hearer calculated for a moment, and said: "Impossible, no matter what design is adopted, the alloy in hand is not enough. And it will take a long time..."

Liu Ri also fell into deep thought: "Senior, if you are in a hurry to use it...Damn it, it seems that none of the earth-drilling companies I know can do it."

Ai Tielang knew that Xiang Shan was preparing for a quantum chip.After listening to everyone's conversation, he glanced at Liu Ri curiously.There are not many martial arts from the ground dragon.

"Forget it, it's not in a hurry." Xiang Shan waved his hand, "Let's bury the vehicle."

The group returned to Pine Eagle City.

Xiang Shanto asked Ai Tielang to bring the others to the place where the knight lives now, and then patted Yuki on the shoulder: "Boy, come with me for a walk. It's time for the exam."

"If you fail, I will expel you from the division."

　It's the last day, please give me the power of the monthly pass!

　　I really want to stay in the top [-] on the monthly ticket list once!
