"In order to ensure that the guide rails are as stable as possible, small cement pillars are built every two meters. The upper ends are polished by hand."
"The lower end of each cement column must have a base of at least 50 cm, and a width of 30 cm above it, which can withstand the force during the acceleration of the guide rail. The height must be at least 50 cm to facilitate inspection, adjustment, maintenance and transformation."
Liu Kaixing is now completely out of vulgar taste, ahem, in short, he has really shouldered the heavy responsibility on his shoulders.
Professor Yang Hua has completed the measurement: "According to the curved surface of the moon, if the rail length is 1,000 meters, if one section is close to the earth and the other section extends, the difference should be more than 28.7 centimeters. The specific data has been placed in the computer.
I would like to ask, what kind of model should we adopt? Is the middle position close to the moon, or is one section close to the moon? ”
"One end. Although the project will be a bit large, the measurement will be relatively simple and the accuracy can be ensured to the greatest extent. In scientific research, accuracy is the first consideration." Liu Kaixing did not raise his head and was calculating and verifying the measurements. result.
"Okay."
Everyone began to pour the cement piers. According to Liu Kaixing's instructions, the lowest cement pier was 50 centimeters high; it extended forward along the central line and the lunar surface, with one every two meters. The last height is 78.7 cm.
In order to simplify the construction process and calculations, after the construction of both ends is completed first, the elevation method of laser measurement is used in the middle, so that accurate columns can be built without calculation.
"That's wrong!" Liu Kaixing suddenly shouted, making everyone around him wait for "instructions."
"Professor Yang Hua!" Liu Kaixing's voice was a little angry. "Your data calculation is wrong!"
"Ah... I used the proportional method. Our guide rail is one thousand meters long; and the average radius of the moon is about 1,737 kilometers, so the angle problem can almost be ignored. So 28.7 centimeters is calculated using the proportional method. Although there is an error , but there should be no problem, it should be said that it is completely within the allowable error range.”
Inexplicably, Professor Yang Hua was a little nervous. In just a few days, this little guy Liu Kaixing's rapid changes made everyone unbelievable, and he no longer treated him like a little kid!
"Fuck you!" Suddenly, Liu Kaixing burst into laughter. Kicked Professor Yang Hua over. It doesn’t matter if the other party is an old man in his sixties. "I'm so blind that I actually recruited a scientist like you! This is an electromagnetic rail test, and the projectile exit speed is as high as hundreds of kilometers per second. Now you are actually telling me that such a serious and precise test does not strictly use angle calculations. No. Strictly testing the thickness and centripetal velocity of the moon's radius under our feet, and he confidently told me that he used an approximate proportional calculation method!
No wonder it lasts a lifetime. He is still a little professor without a formal professional title. I really thought you were underappreciating your talent.
Now, I’m officially telling you, you’re fired! You were fired from Master Company! Just right. In three days it will be the team's turn to change. You go back and stay now, and return to the ground in three days.
Since you have been honest and done some practical things these days, I will give you three more months of salary, 1.2 million. Get out! ”
Liu Kaixing's sudden outburst made the scholars and scientists recruited feel a little uneasy. Although Professor Yang Hua is a bit lazy, his talent cannot be ignored; it can only be said that he is a bit slippery and is a bit sneaky in his work. But such a person was fired so easily! Make the people around you a little uneasy. Everyone has paid too much to join a master company.
"You..." Professor Yang Hua was furious, "You have no right to fire me. I am a recruiter from Gaoshou Company, not a young boy like you! Also, I remember that Gaoshou Company has a policy of not firing employees. ”
"Ha, you have such a wonderful idea. The so-called undismissed employees of the master company refer to the core personnel, the kind of conscientious personnel. Not careless and sloppy eggs like you. I'm so confused!
If you feel that I have no right to fire you, you can go to the top of the company. Fortunately, in this base, Wang Qingwei, general manager of the engineering department of our board of directors, is here, and you can go and appeal. ”
Liu Kaixing was excited when his father almost had an accident; but at this time, this bastard old expert treated the resources his father had sent to the moon with his life in this way, which finally made Liu Kaixing explode. Science does not tolerate sloppiness! Maybe, in your teaching process, you use approximate results. Anyway, you are teaching students to broaden their horizons without using particularly precise data; but right now it is science, the most dangerous and precise science in the world today! At speeds that may reach dozens or hundreds of kilometers per second, any deviation can bring unimaginable consequences!
Seeing the old professor staggering and embarrassed towards the Guanghan Palace base, Liu Kaixing looked coldly at the people recruited from outside, "I know many people think that the Master Company is good and they think they can come in and live a life and provide for their retirement. But If you really think so, you are completely wrong. The success of Gaoshou Company is the result of the hard work of too many people over time.
We welcome people who work conscientiously; but people who are sneaky, sneaky, and not enterprising are not welcome in our company! The losses caused by such people will be unimaginable. Did you know about the plane crash on the ground a few days ago? Just because of a little sloppiness! One person's carelessness can cause tens of thousands of casualties! Trillions of market value losses!
If you want to develop in a master company, give me a serious job now; if you don't want to, you can resign now, and I will give you three more months of salary! ”
Of course no one would leave the master company stupidly! In order to join the master company, I even eliminated all previous relationships. In today's society, everyone can see clearly that there is not much difference between entering the state system or private enterprise. State personnel cannot afford to eat, one by one. On the contrary, a booming company like Master Company is the best place to go.
With the lessons learned from the past, the subsequent work will be much smoother. Everyone works hard and doesn't dare to be careless. Although Liu Kaixing is less than 16 years old today, he has already begun to possess leadership skills. The new generation of the master company is growing rapidly.
All the data have been overthrown and restarted; even the radius of the moon has been rigorously tested and is accurate to millimeters. The rebuilt guide rail pillars were polished by hand during the final correction process. Because the difference is only a few microns in the end, the power tool can no longer provide effective processing at this time. Instead, it is polished gently by hand with sandpaper, and the accuracy is much higher than that of a machine. You know, the most advanced machinery in the world today has basically gone through the manual processing stage.
"Okay. 100% qualified. Each person will be credited once; the reward will be 100,000 yuan starting from the return to the ground." There are rewards and penalties. Although the method is very old-fashioned, it is really easy to use. "Down below, get on the guide rail!"
The thinnest guide rail with a length of 120 meters weighs several hundred kilograms. 49 people worked together to gently lift the guide rail. The gravity in the moon caused the guide rail to weigh only 70 to 80 kilograms. 49 people worked together to easily fix the guide rail tightly, exactly the same as the laser. Slight adjustments by hand, done with care, are so precise.
One...two...after all 16 rails were placed and fixed, it actually took more than six hours. Most of the time, it's a slight adjustment of the angle and so on.
"Adjust the electromagnetic module to ensure that all electromagnetic designs are completely consistent with the data in the computer. I don't allow any mistakes."
Everyone is holding a variety of instruments, some to detect position, some to detect damage, some to detect the quality of wires and cables, etc. Each person is responsible for one project; if the inspection is completed in advance, the instrument will be replaced immediately and other inspections will begin. A small guide rail design requires more than 300 inspections. From straightness, resistance, seams, surface finish, stains, etc., everything must be checked. It also requires three people to cross-check each other. Liu Kaixing will then conduct random checks. Finally, computer shooting simulation calculations are required.
Everyone is sweating so hard that the evaporated water vapor even condenses on the mask. The long hours of work have overloaded the drying mechanism in the space suit.
"That's it for today. Put all the items behind the vehicle; use aluminum plates to cover the guide rails that have been built."
Pieces of three-meter-long and one-meter-wide dusty aluminum plates are placed in a triangular shape, and the top is stuck through grooves. This is to prevent the guide rails from being hit, polluted, etc. Although there is no air on the surface of the moon, a large number of ions will be produced under sunlight, which is harmful to the electromagnetic guide rail. In addition, some small meteorites often fall in the sky. On the earth, these things will definitely be digested by the atmosphere; but the moon has no atmospheric protection and will directly hit the lunar surface. Generally speaking, such meteorites are less than one millimeter and can only pose a slight threat to space suits, but not much. But for guide rails with extremely high precision requirements, a small impact mark may cause disaster. (To be continued...)
