Chapter VII Ground Treatment
In Nie Hongyuan's dream, little Nie Peng, who was only four or five years old, ran over with a wooden stick and shouted at him:
"Dad, I've discovered a secret."
Nie Peng, who looked mysterious, lay in his ear and said in a voice that he thought was very small: "Dad, I found that you can pry away very heavy stones with a small wooden stick, and if I want to pry a big stone, I have to use a big wooden stick, isn't it?" ”
yes, my little Archimedes.
Even in his dreams, Nie Hongyuan was proud of his son. For him is experiencing and growing.
Suddenly, there was a shaking, which woke him up from his dream, and looking at the sleepy look of his colleagues around him, Lao Nie slowly woke up from the dream.
After not returning overnight, Nie Hongyuan, who had been on the sofa for half a night, rubbed his shoulders, took the glasses handed by the young clerk, and threw himself into his busy work.
It is said that last night, the Provincial Geological Bureau reported the news of the meteorite to the National Geological Center, and several experts in the capital got the news and crawled out of the bed overnight and headed for Qi City.
Even the location address sent by his son yesterday has been divided into a rough impact range, and someone went to the scene to collect evidence before dawn.
But at this time, Lao Nie was thinking more, how did his son ride back and forth in a day that was nearly 100 kilometers away from home?
"Blue out of blue!"
The little clerk who gave Lao Nie glasses in the morning turned his head, thinking that he was praising himself, smiled shyly, and worked harder.
·······
Nie Peng, who returned from Taobao in the thrift market early in the morning, is in class in the teaching building at the moment.
That's right, rubbing a course that is neither his major nor an elective.
The professor who gave the lecture was Nie Peng's tutor, the head of the Department of Pharmaceutical Engineering, who had fooled Nie Peng for half a year with the Red Queen hypothesis.
Li Yunfeng.
At the moment, the little old man is shuttling between the desks with his hands behind his back, telling the various energy crises brought about by the evolution of human civilization in a clear and fluent manner.
A group of freshmen in the audience who stretched their necks and waited to be fed listened to him preach and teach with admiration.
Nie Peng looked at the textbook that the junior next to him had never opened:
Molecular and Cell Biology
Like, it's a bit off-topic.
Finally waiting for the recess, Nie Peng squeezed in front of Li Yunfeng with a hippie smile:
"Professor Li, I'd like to discuss something with you."
Li Yunfeng looked at the student in front of him who was proud but had a headache, and didn't know what expression to put on. While cleaning up the textbook, he looked at Nie Peng with a slight smile and did not speak.
"That, that, I'll help you get the textbook" Nie Peng quickly snatched Li Yunfeng's textbook, looking like a complete servile.
Li Yunfeng calmed down, walked in front of him three times in one step, and Nie Peng followed behind him to find a topic. All the way to Li Yunfeng's office.
"You kid, it's rare to be able to hold all the way. Tell me, what's on my mind again? Li Yunfeng knew that Nie Peng was a master who would not give up until he reached his goal, and once because of a continuous experiment, he had to eat and live in the laboratory by himself for a week.
It was also from that time that Nie Peng became a frequent visitor in Li Yunfeng's office.
Li Yunfeng even thought more than once that as long as this kid had the idea of going to graduate school, he would dare to admit him exceptionally.
These days, it is really difficult to find talented and interested students.
"Then I'll be blunt, give a few grams of Elaprase's strain."
"Poof..." A mouthful of strong tea sprayed on the hanger, and the brand-new white shirt was suddenly splashed with tea stains, and the startled Li Yunfeng hurriedly took off the shirt and soaked it in the basin.
People who are almost sixty years old can't stand such fright. If the clothes are dyed, won't my wife break his bones when I go back?
Thinking about it, he couldn't get angry, and his eyes staring at Nie Peng were also gloomy. Li Yunfeng thought that the scholarship that this kid just got a while ago seemed to have been approved by himself, and it was enough to buy this shirt.
"What do you want to be? The value of Elaprase you don't know? Can you give it casually? Li Yunfeng was a little anxious.
"Hey, I don't want a mother, the second and third generations are fine, if you don't believe it, you can operate, I can't do it if I don't reach out." Nie Peng took Li Yunfeng's shirt and rubbed it neatly, working extremely hard, seeing that the good material was about to be crumpled. was quickly stopped by Li Yunfeng.
"Okay, okay, don't make trouble here, your senior brother will have an experiment in two days, I'll give you a batch of strips in a while, and I'll pick it up myself, at most three grams, is there more." Li Yunfeng snatched his shirt and flattened it in distress.
Nie Peng hurriedly smiled and stepped aside, prepared the pen and paper, and waited attentively.
·······
After getting the approval slip and seeing that it was still early, Nie Peng returned to the dormitory, took several sets of photos of the meteorite he brought back, and knocked down two small fragments from the meteorite.
The photos were hung on the international meteorite network, and the fragments were sealed and packaged at the same time, and the mailing slip was filled.
This is a necessary process for auctioning meteorites. The appraisal expert of Meteorite Network will be responsible for issuing an appraisal report for his sample free of charge, and the quality of the sample directly determines the starting price of the subject matter. After the auction is concluded, a fee of 4/1000 of the transaction amount will be taken as a commission.
Nie Peng, who casually threw the mail into the drop-off cabinet, didn't know that the meteorite that was taken by his father to the unit for identification had attracted the attention of many people at this moment.
Three experts from Beijing used various testing instruments to test the data of the stone in a simple laboratory. From time to time there was a shout of excitement.
The scientific research value of this stone alone has far exceeded the amount that Nie Hongyuan transferred to Nie Peng.
This bonus, which fills the gap in the research of lunar meteorites in the province, in the view of Deputy Director Jin, is the most comfortable time to pay out of his pocket in recent times, and he knows that the value of this meteorite is too high to be purchased in the name of the Geological Bureau, so he did a favor.
"Old Nie, you have given us a face this time" Deputy Director Jin congratulated Nie Hongyuan with a red face, and then arranged a hotel for Nie Hongyuan to let him regain his energy.
Jinli knows that for now, the owner of the meteorite is still Nie Hongyuan's son, but he has a share of the credit for taking the lead in the first data collection and submitting the research report to the national scientific research institute.
This is the first lunar surface meteorite without a melting shell found in the province and even in China, and it has extremely high scientific research value and academic value. As of noon today, a number of scientific research institutes have expressed their intention to cooperate and exchange with him, and at this time, only 30 hours have passed since Nie Hongyuan took out the meteorite.
Gionee believes that this matter will attract more people's attention over time, not only domestic scientific research institutes, research institutions and museums. Even foreign countries will look here.
At that time, follow the exchange group and make an academic report in China, and your popularity in the industry will also rise, which is enough to comfort your life.

After receiving a call from the stall owner of the thrift market, Nie Peng remembered that the stainless steel bracket he had changed in the morning had not been taken away, so he hurried over, rented a motorcycle tricycle, and pulled the tripod back to the underground garage.
After transporting the brackets to the moon in batches, Nie Peng found that there were not a few fulcrums that could keep the tripod level on this seemingly flat ground.
It's embarrassing, is it possible that you have to level the ground? So where do you find the materials for paving the ground?
This made Nie Peng, who rarely touches the ground construction, feel very anxious, and said that creativity comes from life, but Nie Peng, who has seen a lot of cement asphalt roads, after estimating these two paving materials, found in despair: these two large-scale leveling methods with the lowest cost on the earth are too difficult to construct on the moon.
Let's talk about cement first, it takes three or four days for normal cement to dry, and even if it is fast-drying cement with strong alkaline, it will take at least three or four hours to dry.
This is one of them, cement in the process of drying, will inevitably form a large number of pores inside, under the normal atmospheric pressure on the earth, these pores will not have much impact on the cement floor, nothing more than the service life.
But what about on the moon? Suppose Nie Peng can wait until the cement is dry before leaving, but at the moment he leaves, the rapidly decreasing air pressure will cause the bubbles in the cement floor to release great energy, and then under the weak gravity, the piece of freshly paved ground will instantly collapse, the scene is simply beautiful.
Then there is asphalt, which is asphalt pavement, which does not need to be dry like cement. Moreover, the texture is not as rigid as cement, which leads to explosions once it enters a vacuum environment.
But this thing needs to be heated and laid, and it needs to be put under pressure to level it, and look at those smooth roads, which one has not been ravaged back and forth by the ton press many times before it was formed?
So at present, neither of these two laying methods will work on the moon.
Nie Peng locked the garage, he was already hungry after being busy for most of the day, so he went home and ordered instant noodles, and extravagantly beat two poached eggs, which was regarded as treating himself.
I pondered for a while, but I didn't have a clue. I simply went to the building materials market to look for it, and I may not have the right materials.
Nie Peng, who couldn't take a break, came to the gate of the building materials city, looked at the few freight trucks full of stones and slowly drove out, and suddenly found that he was a mallet.
"I'm really screwed, why do I have to level the ground, use coarse stones to make the base, and fill the caulks with fine sand." Nie Peng felt that he had been stupid out of a certain realm.
It was much easier to determine the laying materials, Nie Peng's uncle was in the building materials business, and a phone call was made, and he was taken to the yard where the gravel was piled up not long after.
Looking at the pile of rubble piled up into a small mountain, Nie Peng was suddenly a little confused. If you hang other objects on your body, you can carry them with you, so how can you carry this sand?
Looking at the sack in the corner, Nie Peng suddenly felt a little weak.
