Half-immortal civilization

"In order to ensure the stability of the guide rail as much as possible, a small cement pillar is built every two meters. The upper end is polished by hand."

"The lower end of each cement column must have a base of at least 50 centimeters and a width of 30 centimeters above it, which can withstand the force during the acceleration of the guide rail. The height must be at least 50 centimeters or more, which is convenient for inspection, adjustment and maintenance."

Liu Kaixing is now completely out of low-level interests, ahem, in short, he has really picked up the heavy responsibility on his shoulders.

Professor Yang Hua has already completed the measurement: "According to the curved surface of the moon, if the guide rail is 1000 meters long, if one section is close to the ground and the other extends out, the difference should be more than 28.7 centimeters. The specific data has been stored in the computer.

I would like to ask, what kind of model should we adopt?Is the middle position close to the moon, or a section close to the moon? "

"One end. This way, although the project will be a bit large, the measurement is relatively simple and the accuracy can be guaranteed to the maximum extent. In scientific research, accuracy is the first consideration." Liu Kaixing did not raise his head, and was calculating the calibration measurement. result.

"Ok."

Everyone began to pour concrete piers. According to Liu Kaixing's instructions, the lowest cement piers are 50 centimeters high; they extend forward along the median line and the surface of the moon, with one every two meters.The last one has a height of 78.7 cm.

In order to simplify the construction process and to simplify the calculation, after the construction of both ends is completed, the method of measuring the elevation by laser is used in the middle, so that precise columns can be built without calculation.

"No!" Suddenly Liu Kaixing yelled out, 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. The length of our guide rail is 1000 meters; and the average radius of the moon is about 1737 kilometers, and the problem of angle can almost be ignored. So 28.7 cm is calculated using the proportional method. Although there are errors in this way, But there should be no problem, it should be said that it is completely within the allowable range of error."

Inexplicably, Professor Yang Hua was a little nervous.This little guy Liu Kaixing, in just a few days, the rapid changes made everyone a little unbelievable, and he no longer treats him like a little boy!

"I'll fuck you!" Suddenly, Liu Kaixing burst out.Kicked Professor Yang Hua over with one kick.It doesn't matter if the other party is an old man in his 60s. "I was so blind that I recruited a scientist like you! This is an electromagnetic guideway test, and the exit speed of the projectile is as high as hundreds of kilometers per second. Now you are telling me that such a serious and precise test does not strictly use angle calculation. No Strictly tested the thickness and centripetal velocity of the moon's radius under our feet. He even told me that the approximate ratio calculation method was used! You thought you were the author!

No wonder for a lifetime.Still a little professor without a formal title.I really thought you were underappreciated.

Now, I'm officially telling you, you're fired!You were fired by the master company!Just right.After three days, it will be the turn of the team to change. Now you go back and stay, and return to the ground in three days.

Seeing that you have been honest and have done some practical things in the past few days, I will pay you an extra three months' salary, 120 million.Get out! "

Liu Kaixing's sudden outburst made the recruited scholars and scientists 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 slick, and he is a bit sneaky and slippery in doing things.But such a person was dismissed so easily!Make the people around you a little uneasy.Everyone has paid too much to enter the master company.

"You..." Professor Yang Hua was furious, "You have no right to fire me. I am recruited by the master company I am applying for, not you, a brat! Also, I remember that the master company has a policy of not dismissing employees. of."

"Ha, you have such a good idea. The so-called permanent employees of Gaoshou Company refer to the core personnel, the kind of conscientious personnel. It's not a careless and sloppy bastard like you. I'm so confused!

If you think I have no right to fire you, you can go to the top of the company.It just so happens that in this base, Wang Qingwei, the general manager of the engineering department of our board of directors, is here, and you can go to appeal. "

His father's almost accident caused Liu Kaixing to be emotional; at this time, this bastard old expert treated his father's resources to send his life to the moon like this, which finally made Liu Kaixing explode.Science does not allow sloppy!Perhaps, 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, which is the most dangerous and precise science in the world today!At a speed of tens of hundreds of kilometers per second, any deviation can bring unimaginable consequences!

Seeing the old professor staggering towards the Guanghan Palace Base, Liu Kaixing looked coldly at the recruits from the outside world, "I know many people think that Gaoshou Company is good, and they think they can come in and live around and provide for the elderly. But If you really think this way, you are completely wrong. The master company can have today because of the accumulation of too many hard-working personnel.

We welcome those who are serious about their work; but those who steal, rape, play tricks, and do not want to make progress are not welcome in Master Company!The losses caused by such people will be unimaginable.I know about the air crash on the ground a few days ago!Just because of a little sloppy!One person's sloppiness caused tens of thousands of casualties!Trillions in market value loss!
If you want to develop in the master company, you can work hard for me now; if you don't want to, you can resign now, and I will pay you three more months of salary! "

Of course no one will leave the master company foolishly!In order to enter the master company, all previous relationships were eliminated.In today's society, everyone can see clearly that there is not much difference between entering the national system or private enterprises.State personnel can't eat, and there are pieces of it.On the contrary, a thriving company like Master Company is the best place to go.

With the lessons learned from the past, the subsequent work will go much smoother immediately.All of them are conscientious and do not dare to be sloppy.Although Liu Kaixing is less than 16 years old today, he has initially possessed leadership skills.The new generation of the master company is growing rapidly.

All the data have been reinvented; even the radius of the moon has been rigorously tested and accurate to the millimeter.The rebuilt guide rail pillars were polished by hand during the final revision process.Because there is only a gap of a few microns in the end, electric tools can no longer provide effective processing at this time.Instead, it is lightly sanded by hand, and the precision is much higher than that of a machine.You must know that the top machinery in the world today has basically gone through the manual processing stage.

"Okay. 100% qualified. Each person will be credited once; return to the ground and reward 10 yuan to start." There are rewards and punishments. Although the methods are very old-fashioned, they are really easy to use. "Below, on the rails!"

A 120-meter-long, thinnest guide rail weighs several hundred kilograms. With a concerted effort, the 49ers lifted the rail gently.The gravity in the moon caused the weight of the guide rail to be only 49 to [-] jin. With the joint efforts of [-] people, they easily fixed the guide rail tightly, which was exactly the same as the laser.The slight adjustments by hand are so precise under the condition of heart.

One... two... After all the 16 guide rails were placed and fixed, it took more than six hours.Most of the time, it's in slight angle adjustments 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 a little mistake."

Everyone holds various instruments, some to detect the location, some to detect damage, some to detect the quality of wires and cables, and so on.Each person is responsible for one project; if the inspection is completed in advance, the instrument will be replaced immediately and other inspections will start.For a small guide rail design, more than 300 items have to be checked.From straightness, resistance, seams, surface finish, stains, etc., they are all checked, not to mention, and three people cross-check each other.Then Liu Kaixing will conduct random checks.Finally, it has to go through computer shooting simulation calculations.

Everyone is busy sweating, and the evaporated water vapor even condenses on the mask. Working for a long time has overloaded the drying mechanism in the space suit.

"Here for today. Put all the items in the back of the vehicle; protect the built-in rails with aluminum panels."

A piece of three-meter-long, one-meter-wide, dusty aluminum plate is placed in a triangle, and the upper part is clamped by a groove. This is done to prevent the guide rail from being impacted, polluted, etc.Although there is no air on the surface of the moon, a large number of ions will be produced under the sunlight, which is harmful to the electromagnetic guideway.In addition, in the sky, there are often some small meteorites falling.These things will definitely be digested by the atmosphere on the earth; but the moon has no atmospheric protection and will directly hit the surface of the moon.

Generally speaking, some of these meteorites are less than one millimeter, which can only pose a slight threat to space suits, but not much.But for guide rails that require extremely high precision, a small impact mark may cause disaster. (To be continued..)
