Ye Han and the others didn't dare to slack off, and immediately shouted on the radio: "Are you there, Lao Gao?" Call back as soon as you receive it! ”

Gao Kai is much older than Ye Han, and it seems rude to call Lao Gao directly, but the specific situation must be analyzed on a case-by-case basis. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Gao Kai is a colonel, and Ye Han's military rank was also raised by one level after the list was determined, both of them are colonels, and there is no level of rank.

The reason why all the work is arranged by Gao Kai is, first, because Gao Kai has been to the moon for a long time and understands the situation here; Second, Gao Kai is older and more mature and stable, so he was appointed as the interim person in charge by the ground.

Arranged for Ye Han to lead the three groups, which has a very important relationship with Ye Han's rank of colonel.

And Ye Han will be responsible for the security of the entire base in the future, no matter how you look at it, he is one of the predetermined high-level leaders of the base, although he is a little younger, but Gao Kai is not so narrow that he only looks at his age, everyone has a high or low position, but in life they are companions, friends, and comrades-in-arms who depend on each other.

There are only a few living people in this ghost place, and everyone looks up and doesn't see anyone looking down, so there's no need to engage in the same set of superiors and subordinates.

Gao Kai hadn't finished his lunch yet, and immediately put down his chopsticks after hearing the call: "I'm here, what's the matter?" ”

"The first batch of ice has just been tested, and the heavy water content is 0.6 percent, what should I do?"

"So much?" Gao Kai was also surprised, "Have you checked them all?" ”

He is an astronaut who has undergone several years of aerospace training, and he is not in a crash course like Ye Han, and he has a very solid grasp of this kind of knowledge, and he immediately realized the problem.

Everyone else also stopped and looked at Gao Kai in unison.

Even if they didn't understand the reason, they could at least see Gao Kai's expression.

"No, just melted the first furnace."

"Check the rest now, I'll go over now!"

Yuan Yu hurriedly stopped: "Eat first!" ”

"I won't eat it." Gao Kai ran out of the restaurant like a gust of wind, so angry that Yuan Yu stomped his feet.

Wasting food on Earth is waste, and spoiling food on the Moon is a crime, or is it a heinous kind.

Seeing this, the others didn't dare to slack off, and hurriedly ran out, Yuan Yu almost died of anger, but as soon as a burst of fire came up, they heard Gao Kai's voice: "What are you doing here?" Give me all back to eat! ”

A few people ran back in a mess, ate the rest of the food in two bites, and ran away as if reincarnated.

Instead of running to put on spacesuits, they squeezed into the narrow portholes, scrambling to see what was going on over there.

It's just that the light is dim, and I can't see it clearly, except for the shaking headlamp.

After Ye Han outside the cabin finished the communication, he immediately opened the lid of the ice melting machine, the pressure in the container suddenly decreased, the residual water immediately boiled and took away the heat, and Xu Shui quickly froze at the bottom of the container.

Ye Han took out the inner tank of the ice melting machine, turned it upside down on the ground and patted the bottom of the bucket, poured out the remaining sediment, and moved a few pieces of ice into it after loading it back into the ice melting machine, starting the ice melting process with a little apprehension and anticipation.

Gao Kai rushed to Ye Han's side and asked, "How is the situation?" ”

"Just put it in, I'll have to wait a while." Ye Han said.

Gao Kai stared at the ice melting machine, his eyes like they were glued to the lid, and he couldn't move it.

His gaze looked through the glass on the lid and he could clearly see that the ice was melting, and the rising mist was gradually filling the ice melting machine.

After a short while, all the ice cubes finally turned into water, and the internal equipment pumped the water out of the ice melting machine and began to analyze the composition of the water.

Gao Kai's eyes immediately turned to the analysis screen, staring at it without moving.

The small screen only displayed the analysis results, not the analysis progress bar, but Gao Kai didn't care and waited patiently for the analysis results.

He knew too well what 0.6 percent meant.

The results of the analysis finally appeared on the screen, and Gao Kai rushed over like a wild dog on the loose, his eyes almost on the screen: "It's still 0.6...... Ye Han, go back to the meeting with me immediately, Duan Zhiyang, Xu Hua! ”

"Here!"

"You two stay and continue to analyze, and all the samples will be analyzed once!"

"Yes!"

Gao Kai turned around and walked back: "Hu Liang, go back to the living cabin for a meeting immediately!" ”

Hu Liang's reply came over the radio: "Received, I'll be there soon!" ”

After a few steps back to the living cabin, several members of the team who picked up the portholes immediately came over to help Gao Ye and the others take off their spacesuits, and a few minutes later, several people entered the restaurant together.

Gao Kai asked eagerly on the radio, "Hu Liang, where are you?" ”

"Vegetable garden, get dressed." Hu Liang replied.

It takes a little time to put on and take off the spacesuit, and every time the necessary tests must be carried out, there is no problem to get out of the cabin, just now Gao Kai was hot-headed, and rushed out without testing at all, if he was known by the ground, he would inevitably be punished one by one.

"Then you listen on the radio first." Gao Kai said.

"Good!"

Gao Kai raised his head: "Comrades, the ice retrieved by the three groups contains 0.6 heavy water, do you understand the meaning of this content?" ”

Everyone didn't speak, looking at Gao Kai suspiciously, even Ye Han was no exception.

Ye Han only knew that the high content of heavy water in the ice was beneficial, but he couldn't say what the specific meaning was.

Gao Kai didn't want to sell it, and asked himself: "This means that we can separate heavy water at a very low cost, and we can produce heavy hydrogen in large quantities...... The fusion reaction of heavy hydrogen and helium-3 does not produce neutrons, and you may not know that the main reactor of the base is a magnetic confinement fusion reactor, and the main fuel is heavy hydrogen and helium-3! ”

Everyone suddenly realized that after more than half a year of aerospace training, no matter how bad the level is, they still know what the second-generation nuclear reaction is.

Ye Han asked everyone's hearts in surprise: "Old Gao, is controlled nuclear fusion completed?" ”

Gao Kai shook his head: "There is this plan above, there must be a technological breakthrough, and maybe it is also the result of international cooperation." ”

"It's not an experimental pile, is it?" Ye Han was worried.

"Probably not, I learned about it after I knew about it."

"Are magnetic confinement reactors reliable?"

"I don't know, it should be fine." Gao Kai said, "This thing relies on a magnetic field to confine the fusion reaction, and the moon has a low temperature and no air pressure, so it can easily achieve superconductivity, which is very important for magnetic confinement reactors...... We are now talking about heavy water, not fusion reactors, and I am not engaged in reactors. ”

Ye Han grinned: "I don't want to sit under my ass every day with a large amount of hydrogen. Play. ”

Gao Kai glared at Ye Han: "Leave it alone and stay away from the main base." ”

"I'm fine." Ye Han accepted it when he saw it.

"Let's move on to heavy water." Gao Kai finally straightened out the crooked building, "This discovery is of great significance to the country and the Moon Palace plan, and it must be reported to the command center as soon as possible, but it will take a few hours for the satellite to fly back, so I suggest that we discuss a report charter first......

"What else is being discussed? Report directly and let the ground get an idea! Hu Liang said on the radio, "We don't have heavy water separation equipment in our hands, and the function of the water treatment tank is not to separate heavy water." ”

"I know, but heavy water can't be electrolyzed, we can use this method to collect heavy water!" Gao Kai said.

The water treatment module has two main functions, one is to provide astronauts with clean domestic water, and the other is to electrolyze water to produce oxygen for astronauts to breathe.

Astronauts cannot lack oxygen, and in any case, electrolyzed water cannot be omitted, and heavy water is just obtained by the way.

"Do we have distillation equipment?" Ye Han suddenly asked.

"Nope."

"Then you can only electrolyze and separate heavy water?" Ye Han was annoyed, "This is good, all the ice we get back is electrolyzed, we have to recombine hydrogen and oxygen if we want to use water, is it possible to arrange a special place to burn hydrogen and oxygen for water?" ”

He knew something about separating heavy water, and the only suitable methods on the moon were electrolysis and rectification.

Needless to say, the so-called distillation method is a method that uses the characteristics of heavy water to obtain heavy water through repeated evaporation by taking advantage of the high boiling temperature of heavy water.

However, the boiling temperature of heavy water is only 101.42 degrees Celsius, and the boiling temperature difference of light water is very small, and there is no pressure on the surface of the moon, so it is necessary to use a pressure vessel to use the distillation method, which is not as convenient and simple as the electrolysis method.

Gao Kai gritted his teeth: "Overcome it for the time being, and use circulating water for a while." ”

Ye Han's eyes darkened, and he felt as disgusting as eating a fly, and the faces of the others were not much better...... Ye Han is definitely not the only one who dislikes circulating water, and even Gao Kai is no exception.

Drinking urine all day long, no one can feel comfortable.

The door opened, Hu Liang finally rushed back to the living cabin, and before he could sit down, Duan Zhiyang's voice came from the radio: "Team Leader Gao, I'm Duan Zhiyang!" ”

"Please!"

"The third analysis has a result, and the heavy water content is 0.62%!"

"0.02 higher? Is it accurate? ”

"Analyzed it twice."

"Got it, go ahead!" Gao Kai sighed, "There is an extra 0.02, how much heavy water does such a large ice lake have to store!" ”

"And that's not all." Hu Liang said, "There are a lot of glacial lakes in the Arctic, and maybe there are even more ones!" ”

"Makes sense!" Gao Kai's eyes lit up, "We should take the initiative and investigate all the ice lakes......

"Are you dreaming?" Hu Liang was not polite at all, "Let's just have so much equipment, we can't even get out of the crater, and we still investigate the ice lake?" ”

"Let the ground deliver the equipment!" Gao Kai said viciously.

"Then you have to agree to talk about it." Hu Liang-for-tat, "Our task is to dig the base, everything is easy to say after the base is built, if the base is not built well, what can be done if there are more heavy water reserves?" Will you be able to move the glacial lake back to Earth? ”

Hu Liang's words were like a basin of ice water poured on Gao Kai's head, the ice made him stunned for a while, and his originally excited appearance gradually became depressed, and after a while, he frowned and smiled bitterly: "You're right, I want to deviate, wait for the satellite to come over and report to the ground, let the above take the idea." ”

At the end of the meeting, there is still a short time before the satellite returns, the work that should be done can not be put down because of this little thing, everyone should rest and rest, and Ye Han returned to the water treatment cabin, pumped out some water from the water tank and injected it into the electrolytic cell, and turned on the power to no longer need to be managed.

The electrolysis plant automatically collects the gas, compresses it and liquefies it before storing it in cylinders.

The efficiency of the electrolysis equipment is good, and after a while, the oxygen tank, which is not much bigger than a brick, is filled with sky-blue liquid oxygen, Ye Han replaced it with a new box, and threw the old one on the ground and left it alone.

The cylinder for storing oxygen is particularly interesting, not the usual cylindrical shape on the ground, but a boxy box with a lid that can be opened!

This design is because the ambient temperature in the crater is lower than the melting point of oxygen, and after the liquid oxygen is placed for a period of time, it will naturally solidify because of the decrease in temperature.

Hydrogen is an important industrial raw material, and in the future, when the base is built, it will definitely be indispensable to use hydrogen. But the melting point of this thing is too low to solidify naturally on the surface of the moon, and it can't be solidified and preserved like oxygen, and the temporary base has limited resources, so there are not so many storage boxes for hydrogen, so it can only be wasted and let go.

The use of hydrogen storage metal is also a good choice, but hydrogen is made from water, and where there is water, there is hydrogen, and the cost is pitifully low.

After more than two hours, the eight gas tanks were all filled and neatly arranged in a row, and the huge temperature difference between the box and the ground caused the temperature in the box to lose quickly, and as long as you waited for a while, you could take out the oxygen ice.

The first gas box had been thrown on the ground for more than half an hour, and Ye Han picked up the box without the slightest feeling of liquid shaking; Looking at the barometer again, the hands have been reset to zero.

"That's it!" Ye Han said hello, Duan Xu and the two immediately came over, and under the witness of the two companions, Ye Han opened the lid of the gas tank, and a piece of light blue transparent oxygen ice appeared in front of everyone.

Xu Hua praised: "This thing is really beautiful, if you don't know this thing, people will believe it if you say it's a gem." ”

"Then this piece is for you, and give your wife a set of jewelry." Ye Han handed the oxygen ice to Xu Hua.

Xu Hua received it in his hand, pouted and said: "Hurry up and put it away, how can you say that it is also the first oxygen brick we made, go back and make a mark, maybe it will still be a cultural relic." ”

"Forget it." Ye Han laughed, "Hurry up and send Curry." ”

"Got it!" Xu Hua agreed loudly and sent the oxygen ice into the warehouse as quickly as possible.

Although the temperature of the lunar surface is low, it is safest to store the oxygen bricks directly in the open air, which is likely to be lost due to sublimation, so it is safest to store them in a constant temperature warehouse.

There was still some water left in the electrolysis cell, and Ye Han said without thinking: "The heavy water content in this must be more than 0.6%, come and help!" ”

Ye Han called Duan Zhiyang to work together, drain the remaining water in the electrolysis cell into the container, freeze it into ice and put it aside, and keep it for the right time in the future to extract the heavy water.

The water ice is white, the oxygen ice is blue, and it can't be mixed up when you put it in the warehouse, but with the temperature of the lunar surface, it doesn't matter if the water ice is stored for tens of thousands of years, there is no need to use this thing to grab the oxygen ice place.
