MTL - Into Unscientific-Chapter 479 Gradient warriors, fit together!
In the warehouse.
Looking at Cao Yi with the expression "Such a tall thing is assembled here?"
Li Hua and Ge Tongyou couldn't help laughing together.
really.
Right now, this warehouse, which looks a bit like a cargo workshop, is difficult to combine with a precision instrument such as a gravity gradient meter at almost any time.
Not to mention that compared with the gravity gradiometer of ordinary concept, the nature of this gravity gradiometer is even more extraordinary:
Although it is just a beggar version, it is likely to open a new door for China's national defense.
Actually.
Before starting from the 29th Institute, Cao Yi was popularized by some bigwigs from the 29th Institute about the significance of this gravity gradiometer with very intuitive data:
Currently, the accuracy of the top gravity gradiometer that has been published in the world is 10^12m/s, which is a world record on the surface.
Neon, Gaul, Italy, and Switzerland have gravity gradiometers with an accuracy of 10^11m/s.
The accuracy of the gravity gradiometer that may be possessed on the other side of the sea is on the order of 10^13m/s, and at most it will not exceed 10^14m/s—unless they really get Zentraedi technology.
However, the accuracy of China's most top-notch gravity gradiometer is only .
10^9m/s level.
This is also thanks to Professor Huang Danian's dedication after returning to China, otherwise the current accuracy may not even be 10^8m/s.
At present, the gravity gradiometer that Xu Yun replaces the ultra-cold rubidium atoms with lone point particles, the most perfect accuracy can be as high as 10^16m/s!
Indeed.
10^16m/s is just a theoretical perfect value, and it takes a lot of effort to reach this step.
But even the current beggar version of the gravity gradiometer can reach about 10^14m/s.
So as long as a piece of equipment can achieve this accuracy in actual combat, then the rest is how to dress a beggar as a prince, and the feasibility is still very high.
So Cao Yi wanted to come.
This kind of thing that can be said to involve a new chapter in the national defense industry has to be carried out in a super-sophisticated laboratory from the very beginning, and it has to go through several rounds of political review to get a glimpse.
Wait until after the project starts.
There must be a bunch of old academicians who look like senior experts standing around the instrument, and a certain high-ranking boss personally assembled the last part, and finally the equipment slowly started up in the eyes of everyone's anticipation and joy.
It turned out to be good.
Li Hua and Ge Tongyou actually proposed the idea of assembling here?
This is too sorry for the forceful style of this thing.
Seeing that Cao Yi was still in a daze, Li Hua couldn't help but stepped forward, patted him on the shoulder with a smile, and said:
"Major Cao, your thinking may have fallen into a misunderstanding."
"Although the gravity gradiometer is very important, its core link lies in the calculation of principles, in the production of parts, not in the specifications of the appearance."
"Its finished product is meant to go up to the mountains and down to the deep sea. Why do we need to build a glamorous birth banquet for it?"
"No matter how high the specifications are, if you don't have the strength, even if we replace our warehouse with Milan Fashion Week, it will be useless for you to have a CEO of some big brand next to you. Their bald heads are more attractive than yours. eye."
Hear this statement.
Ge Tongyou next to Li Hua also nodded with emotion, with a hint of remembrance in his eyes:
"Yes, Major Cao, look at the achievements of our country in the past, don't talk about the ceremony of the press conference in the early years, and you can't even show your face."
"For example, in the Dongfanghong satellite that I worked with the commander-in-chief back then, there were a few bamboo mats and quilts next to the main console of the rocket launch—and that's not all. At that time, we were afraid that the satellite across the sea would capture pictures of people's lives. Our trousers They are all hanging out in the assembly workshop."
"Even the light of hope for our country was born on a humble boat?"
"Our generation never engages in those empty-headed battles. Efficiency is always the first. Whichever leader dares to show off, everyone can push him out in minutes!"
Looking at Ge Tongyou, who was quite high-spirited.
Xu Yun also felt a surge of emotion in his heart.
The era that Ge Tongyou experienced was very complicated. Some people think it is bitter and some people think it is sweet. People with different experiences have different impressions of it.
But whoever it is, will not deny one point:
The workers of that era were the purest. They dared to contribute to their ideals and challenged their superiors. They were the real "grandfathers of workers".
It's a pity that I was born several decades late, so I couldn't see the demeanor of Wang Lao and the others riding the wind and waves in that era.
And just when Xu Yun's mind was in a daze.
Cao Yi on the side also seemed to have some unique insights, and the whole person suddenly stood upright like a pine tree:
"I understand, Mr. Li, then I will have the audacity to 'watch the ceremony' here. If there is anything else that needs help, just ask!"
Actually, in terms of position and affiliation, Li Hua is not Cao Yi's immediate superior, and he is not even qualified to give instructions to Cao Yi.
But the current situation is not a combat mission, at most it is to help disassemble and assemble equipment, so out of respect for Li Hua and Li Hua, Cao Yi voluntarily became a subordinate.
Li Huajian nodded politely at him, and then called in assistants to get him ready to assemble the equipment.
As Li Hua said before.
The most important part of the gravity gradiometer lies in the calculation and the production of parts, and there must be no mistakes in these two links.
And after the parts are produced.
The gravity gradiometer can change from a baby who is carefully cared for to a muddy leg with strong skin and resistance.
There are only a few parts to pay attention to during the entire assembly process, and they are basically related to airflow, signals and the like.
So fast.
Including Xu Yun and Cao Yi, everyone began to do coolies.
"Two people, move this metal cover out, no, no, no, don't use a crane, four or five people can handle it!"
"Xiao Liu! Move the case to the left to make room for the filter!"
"Don't open the intake pipe on the left, this thing is very hypocritical, and it really needs to be assembled in a sterile environment. Xiao Zhou has already gone to get the simple sterile partition."
"borrowed borrowed"
More than half an hour later.
The sorted equipment was neatly placed in a corner of the warehouse.
Ge Tongyou took the structure diagram and led the people to start the final assembly.
Mentioned earlier.
As a kind of exploration equipment, the gravity gradiometer itself cannot be pushed on the ground with wheels or the like. Its main carrier is an aircraft or a warship.
Leaving aside the situation of the latter, the former includes all kinds of medium-sized helicopters.
Therefore, it is not difficult to see from the carrier that the volume of the gravity gradiometer is actually not large.
So it's time for assembly.
The main purpose of Ge Tongyou and others is to connect the various parts on the line, as well as the legendary factory skills
Hit the screw.
This is also the reason why Ge Tongyou and Li Hua dared to assemble on the spot.
Of course.
When encountering some special structures, it still needs the assistance of external equipment, such as manipulators and so on.
Compared to the previous division of labor, the assembly link is also divided into three modules.
Among them, Xu Yun, as the person in charge of the measurement module, was naturally assigned the related tasks of the measurement module at this time.
Two days ago, when Xu Yun first arrived at the Xichang Base, only Academician Pan and Wang Lao were by his side, and he could only sleep alone.
But now with the intention to achieve.
Academician Pan called several members of Xu Yun's original "Listening to Truth" project team to the Xichang base from the science department, and asked them to fight Xu Yun.
With these tools and people present, Xu Yun also has a helper, and sleeps. Well, he sleeps alone.
Right now.
Tang Fei and others are assisting Xu Yun in the final process, that is,
Loading of Pangu particle container.
After all, the gravity gradiometer is so big, it is impossible to insert the collider into it to produce Pangu particles on site, and the circumference of the smallest collision orbit is only one or two hundred meters.
So they can only process the Pangu particle in the laboratory first, and then package it into the measurement module.
"Dr. Xu, the container is here!"
On the co-pilot of a small transport vehicle, Zhang Han, who was riding a forklift for the first time, was waving at Xu Yun with a full face, and his hair fluttered messily in the wind.
Wait until the car stops.
The girl quickly jumped out of the car and said to Xu Yun:
"Dr. Xu, there are a total of six cans of ultra-low temperature Pangu particles, and the relevant data has been verified to be correct. It should be enough for us to use this time."
Xu Yun nodded to her:
"Thanks for your hard work."
Mentioned earlier.
Lone point particles are originally uncharged and belong to neutral particles.
Theoretically speaking, the neutron-like degenerate matter can only be preserved in neutron stars.
But then Xu Yun thought of a way, which is to use π mesons to convert the isolated point particles without any electrical properties into a metastable electronic state for storage.
Of course.
This kind of storage is still different from the storage ring of a conventional particle collider, because the storage ring of a collider is very, very large.
Students who have watched the TV series "Three-Body Problem" should have some impressions of the Liangxiang Accelerator, that is, the scene where Wang Miao took pictures of Yang Dong.
That scene is actually Yanjing’s electron-positron collider, located at the Institute of High Energy Physics, Chinese Academy of Sciences, No. 19, Yuquan Road, SJS District, BJ City.
The tube wrapped with copper wires in front of Wang Miao when he took the photo is the storage ring.
By the way.
The storage ring of the Yanjing Electron Positron Collider is a double-ring structure, that is, there are two storage rings.
One ring contains high-speed moving electrons, and the other ring contains the antimatter of electrons, that is, positrons.
all in all.
Taking into account the size of the storage ring.
Xu Yun’s final plan is to start with the twist angle θ of the outer orbit of the Pangu particle, and inject π mesons from the twist angle θ, so that the Pangu particle has a superfluid-like property.
Then irradiate with a near-infrared light with a high resonance, which can meet the conditions for leaving the trap, and successfully 'extend' the Pangu particle's lifespan to 15,000 seconds.
Converted into hours, it is more than four hours.
Then Xu Yun called Tang Fei, Liang Haoran and other idiot authors who forgot their names, and worked together to carry the container down.
"Dr. Xu, here it is!"
An engineer from the Xichang Satellite Launch Base called Xu Yun's name, and threw a handle towards Xu Yun half a meter away, and Xu Yun also caught it cleanly:
"Thank you, Mr. Huang."
Seeing Xu Yun's "skillful and vigorous", the man named Huang Gong's eyes lit up immediately, and he gave Xu Yun a thumbs up.
Xu Yun smiled, but did not speak.
Ordinary people may need to put both hands on this handle in order to stabilize it.
However, for Xu Yun who has already practiced "Lai Fu Jian Jue" to the middle level, it is a basic practice to pick up this thing with one hand.
Then he turned around, carefully took out a disc from a box on the right, aligned it with the groove of the mechanical arm, pulled a sheath bolt, and pressed it hard.
click—
With a soft sound, the disk was inserted into the groove.
Then Xu Yun raised his head again, and said to Zheng Lei at the other end:
"Xiao Zheng, pass me the connecting cable."
Zheng Lei hastily pulled out a yellow wire from the module he was in charge of, and arrived in front of Xu Yun:
"Here, God Xu."
"Thanks."
Xu Yun thanked him, took the yellow line, took the diagram, and started proofreading.
According to the original structure designed by Huang Yuting.
The three arms of the gravity gradiometer will be loaded with six or three pairs of measurement modules.
These measurement modules are all circular with a diameter of 7.5 cm, thicker than the width of the mechanical arm, and are embedded at the front and rear ends of the mechanical arm.
If you take any one of the ends and look at it, the shape is somewhat similar to the famous turntable machine gun - the main body of the machine gun is the mechanical arm, and the measuring module is the magazine.
These measurement modules have been preset with very fine measurement components, and they have been uniformly tested in the previous handover process without any flaws.
So Xu Yun and the others don’t need to operate the inside of the module, they only need to install the container with Pangu particles and the module.
For example, the previous embedded disc, and the current **** connection.
The yellow wire in his hand is connected to a laser alignment device—this thing is said to be an instrument, but it is actually the size of a thumb.
Its function is to prevent the core balance module from having problems, so the yellow line should be aligned with the
Xu Yun carefully proofread the structure diagram:
"Found it, sensor A3 interface."
click—
The connection line is in place smoothly.
Except for Xu Yun, other modules are also being carefully assembled.
for example
The refrigeration link required to ensure low temperature.
"Hey, this thing can reach the cooling effect of 50nK level?"
In the warehouse.
Looking at the refrigeration module in front of him that was only half the size of a microwave oven, the youngest Liang Haoran couldn't help raising his eyebrows, and asked Tang Fei beside him:
"Old Tang, you brought this thing, right? What's the price? If it's cheaper, I'll make one when I go back."
Although he and Tang Fei were not classmates in the same year, they were fellow villagers in the same place. They had always had a good relationship and belonged to the state of conjugated father and son.
Tang Fei gave him a blank look when he heard the words, and gave him a **** without mercy:
"Convex, laser cooling and magnetic potential well evaporative cooling equipment, the effect is infinitely close to absolute zero. Looking at this performance, you know it is definitely not cheap. Where did you have the courage to ask the price?"
Liang Haoran seemed very optimistic, he didn't care about his friend's contempt at all:
"Just tell me the price, let me open my eyes?"
Tang Fei was silent for a few seconds, and raised three thumbs up:
"3.37 million, I heard that the cost of the control system is no less than one million, and the number of units in the country does not exceed ten."
"Of course, this is not because the old technology is immature, but because it is relatively rare to use this temperature outdoors."
"However, if our trial operation is successful this time, it is estimated that there will be a big order in this business."
"hiss"
Liang Haoran suddenly took a deep breath, looked at the refrigeration module in front of him again, and smacked his lips:
"Such a thing costs three million?"
Tang Fei snorted coldly, but did not speak.
But soon, Liang Haoran thought of another question, and asked Tang Fei in a thief-like way:
"Hey, Old Tang, no matter how expensive this thing is, it's equivalent to a refrigerator—so it can talk dirty?"
Tang Fei:
“.?”
Yes, another player who plays with Atomic Heart and Magic.
Huh.
Why do you say again?
The docking of the refrigeration module and the container is an important link in the entire assembly process.
But still that sentence.
Importance and difficulty are not the same concept.
The more important the equipment, the less likely it is to make mistakes in the connection process—because it has been protected layer by layer during production.
It’s like a mushroom bomb, you can light a lighter next to it for a hundred hours without any problems.
So fast.
More than an hour later.
When the time was close to ten o'clock in the morning, a gravity gradiometer finally appeared in front of everyone in its entirety.
This instrument is completely black, and its height is about two-thirds of an adult. That is, about one Pandora.
The bottom of the instrument is a metal base with a thickness of ten centimeters and a diameter of about one meter.
Don’t look at the bottom as inconspicuous, it is actually the information transmission center of the gravity gradiometer, and there are many small signal processors inside.
This thing is to the gravity gradiometer what An Xin is to Gao Qiqiang. Without An Xin, Gao Qiqiang is just a stinking fish seller.
On the bottom of the support is a cylinder with a height of about 50 centimeters. Inside the cylinder are the containers and cooling modules filled with Pangu particles, the external lattice plate, the three-dimensional electrostatic balance equipment designed by Huang Yuting, etc.
Above the cylinder is a hemispherical cover with the opening facing upwards.
There is a vertical signal receiver inside the hood, and three mechanical arms are attached to the inner wall of the hood.
If this description is not easy to understand, you can imagine such a picture:
A can of Wanglaoji is placed on a plate of mosquito coils. On top of Wanglaoji is a small bowl. In the center of the bowl stands a stick of Green Arrow chewing gum. Tomato sauce is smeared on three sides of the inner wall from the mouth to the bottom of the bowl.
The mosquito coil is the base, Wanglaoji is the cylinder, and the small bowl is the cover—the three strips of tomato sauce are the three inner walls attached.
After the gravity gradiometer is assembled.
Li Hua and Ge Tongyou first powered it up once, and the instrument started buzzing quickly—this means that the basic power supply line is normal.
See this scenario.
Li Hua beckoned to the assistant again:
"Xiao Guo, take out the things."
