Inside the warehouse.
Looking at Cao Yi with an expression on his face: "Such a high-end thing is being assembled here?"
Li Hua and Ge Tongyou couldn't help but smile together.
really.
At present, this warehouse, which looks somewhat like a cargo workshop, is difficult to integrate with precision instruments such as gravity gradiometers at almost any time.
Not to mention that compared to the ordinary concept of gravity gradiometer, the properties of this gravity gradiometer are even more extraordinary:
Although it is just a beggar version, it is likely to open a new door for China's national defense industry.
Actually.
Before setting off from the 29th Institute, Cao Yi was taught by some big guys from the 29th Institute the meaning of this gravity gradiometer using very intuitive data:
At present, the accuracy of the most advanced gravity gradiometer published in the world is 10^12m/s, which is an apparent world record.
First-class countries such as Neon, Gaul, Italy, and Switzerland have gravity gradiometers with an accuracy of 10^11m/s.
The accuracy of the gravity gradiometer that may be available 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 obtain Zenith star technology.
However, the accuracy of China's most advanced gravity gradiometer is only.
On the order of 10^9m/s.
This is also thanks to Professor Huang Danian’s efforts after returning to China, otherwise the current accuracy may not even be 10^8m/s.
And now Xu Yun's gravity gradiometer, which uses lone point particles to replace ultra-cold rubidium atoms, has the most perfect accuracy of up to 10^16m/s!
True.
10^16m/s is just a theoretical perfect value, and a lot of effort is needed to reach this point.
But even the current beggar version of the gravity gradiometer can reach about 10^14m/s.
So as long as the equipment can achieve this accuracy in actual combat, then the remaining problem is how to dress a beggar into a prince. The feasibility is still very high.
So I wanted to come to Cao Yi.
This kind of thing, which can be said to involve a new chapter in the national defense industry, will have to be carried out in a super-precise laboratory at first, and it will have to go through several rounds of political review before even looking at it.
Wait until the project starts.
There must be a bunch of old academicians who look like senior experts standing around the instrument. A certain high-ranking boss personally assembles the last parts. Finally, the equipment slowly starts up and ascends to the sky under everyone's expectant and delighted eyes.
The result was good.
Li Hua and Ge Tongyou actually proposed the idea of assembling here?
This is too sorry for the extreme quality of this thing.
Seeing that Cao Yi still looked confused, Li Hua couldn't help but step forward, smiled, patted his shoulder, 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 the principle and the production of parts, not in the specifications."
"Its finished product is meant to go up the mountains and into the deep sea, so why do we need to build a glorious birth party for it?"
"No matter how high the standards are, if you don't have the strength, it will be useless even if we replace our warehouse with Milan Fashion Week and give you a CEO of some big brand next to you. People's bald heads will be more attractive than yours." eye."
Hear this.
Ge Tongyou, who was beside Li Hua, also nodded with emotion, with a hint of reminiscence in his eyes:
"Yes, Major Cao, look at the achievements of our country in the past. In the early years, there was no such thing as a ceremonial press conference. You couldn't even show your face."
"For example, when I worked on the Dongfanghong satellite with the commander-in-chief, 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 living. Our The pants are hanging in the assembly workshop."
"Even the light of hope for our country was born on an inconspicuous boat, wasn't it?"
"Our generation will never engage in vain battles. Efficiency is always the first priority. If any leader dares to show off, everyone will push him out in a minute!"
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 thought it was bitter and others thought it was sweet. People with different experiences had different impressions of it. Even today, they all have different opinions.
But no one will deny one thing:
The workers of that era were the purest. They dared to dedicate themselves to their ideals and dared to challenge their superiors. They were the real 'worker grandfathers'.
It's a pity that I was born a few decades too late, so I couldn't see Mr. Wang and the others riding the waves in that era.
And just when Xu Yun's mind was misty.
Cao Yi on the side seemed to have some unique insights, and his whole body suddenly stood upright as if he was a pine tree:
"I understand, Mr. Li, then I will have the audacity to 'observe' the ceremony. If there is anything else you need help with, just ask!"
In fact, in terms of position and affiliation, Li Hua is not Cao Yi's direct superior, and he is not even qualified to give instructions to Cao Yi.
But this situation is not a combat mission. At most, it is helping to disassemble and assemble equipment. Therefore, out of respect for Li Hua and the other two, Cao Yi volunteered to become a subordinate.
Li Huajian nodded politely to him, then called for an assistant and asked him to prepare to assemble the equipment.
Just like Li Hua said before.
The most important part of the gravity gradiometer is the calculation and parts production. There cannot be any mistakes in these two links.
And after the parts are produced.
The gravity gradient meter can transform a baby who is carefully cared for into a muddy leg that can withstand beatings.
There are only a few parts that need attention during the entire assembly process, and they are basically related to airflow, signals and the like.
So it's quick.
Everyone, including Xu Yun and Cao Yi, began to work hard.
"Two people, come and move this metal cover out, no, no, no, don't use a crane, four or five people can handle it!"
"Xiao Liu! Move the chassis to the left and make room for the filter!"
"Don't open the air intake pipe on the left yet. This thing is very pretentious. It really needs to be assembled in a sterile environment. Xiao Zhou has already gone to pick up the simple sterile partition."
"Borrowed and borrowed"
More than half an hour later.
The classified equipment was neatly placed in a corner of the warehouse.
Ge Tongyou took the structural diagram and led everyone to start the final assembly.
Mentioned before.
As a kind of exploration equipment, the gravity gradiometer itself cannot be pushed on the ground by wheels or the like. Its main carrier is an airplane or a warship.
Let’s not talk about the latter for the moment. The former includes various types of medium-sized helicopters.
Therefore, it is not difficult to see from the carrier that the size of the gravity gradiometer is actually not large.
So it’s time to assemble it.
The main purpose of Ge Tongyou and others is to connect various parts on the line, and to use the legendary secrets in the factory
Hit the screw.
This is also the reason why Ge Tongyou and Li Hua dared to assemble it on site.
Of course.
When encountering some special structures, external equipment is still needed to assist, such as manipulators, etc.
Similar to the previous division of labor, the assembly process is also divided into three modules.
Among them, Xu Yun, as the person in charge of the measurement module, was naturally assigned the tasks related to the measurement module.
Two days ago, when Xu Yung first arrived at the Xichang base, he was only accompanied by Academician Pan and Mr. Wang, and he could only sleep alone.
But now as the intention is achieved.
Academician Pan then shouted several members of Xu Yun's original 'True Listen' project team from Congke to the Xichang base and asked them to attack Xu Yun.
With the presence of these tools, Xu Yun also had helpers, so he could sleep alone.
At this moment.
Tang Fei and others were assisting Xu Yun in the final process, which was
Loading of Pangu particle container.
After all, the gravity gradiometer is only that big, and it is impossible to plug the collider into it to produce Pangea particles on site. Even the smallest collision orbit has a circumference of one or two hundred meters.
Therefore, they can only process the Pangea 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 truck, Zhang Han, who was riding a forklift for the first time, was waving towards Xu Yun with a flying face, his hair fluttering messily in the wind.
Wait until the car stops.
The girl jumped out of the car nimbly and said to Xu Yun:
"Dr. Xu, there are six cans of ultra-low-temperature Pangea particles in total. The relevant data has been verified and it should be enough for us to use this time."
Xu Yun nodded towards her:
"Thanks for your hard work."
Mentioned earlier.
Solitary point particles are originally uncharged and are neutral particles.
Theoretically speaking, this kind of neutron-like degenerate matter can only be preserved in neutron stars.
But then Xu Yun thought of a way to use pions to convert lone point particles without any electrical properties into metastable electronic states 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 "The Three-Body Problem" should have some impression of the Liangxiang accelerator, where Wang Miao took photos of Yang Dong.
That scene is actually the Yanjing Electron Positron Collider, located at the Institute of High Energy Physics, Chinese Academy of Sciences, No. 19, Yuquan Road, SJS District, BJ City.
When Wang Miao took the photo, the tube wrapped with copper wire in front was 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.
Inside one ring are electrons moving at high speed, and inside the other ring are the antimatter of electrons, that is, positrons.
all in all.
Consider the size of the storage ring.
Xu Yun's final plan is to start from the twist angle θ of the outer orbit of the Pangea particle core, and drive pions from the twist angle θ, so that the Pangea particle has a superfluid-like behavior.
Then, by irradiating it with a high-resonance near-infrared light, the conditions for exiting the trap can be met, and the Pangea particle can be successfully 'extended' to 15,000 seconds.
Converted into hours, it’s a little over four hours.
Xu Yun then called for Tang Fei, Liang Haoran and other helpers whose names the idiot authors had forgotten, and worked together to move the container down.
"Dr. Xu, give it!"
An engineer from the Xichang Satellite Launch Base called Xu Yun's name and threw a handle towards Xu Yun from half a meter away. Xu Yun also caught it with one hand neatly:
"Thanks, Huang Gong."
Seeing Xu Yun's "excellent skills", the man named Huang Gong's eyes suddenly lit up and he gave Xu Yun a thumbs up.
Xu Yun smiled and said nothing.
Most people may need both hands to hold this kind of handle for stability.
However, for Xu Yun, who has already practiced "Laifu Sword Technique" to the middle level, picking up this thing with one hand is considered a basic skill.
Then he turned around, carefully took out a disk from a box on the right, aligned it with the groove of the robotic arm, pulled open a sheath bolt, and pressed hard.
Click——
With a soft sound, the disc was embedded in the groove.
Then Xu Yun raised his head again and said to Zheng Lei on the other end:
"Xiao Zheng, please pass me the connection cable."
Zheng Lei quickly pulled out a yellow thread from the module he was responsible for and put it in front of Xu Yun:
"Here, Xu Shen."
"Thanks."
Xu Yun thanked him, took the yellow thread, took the schematic 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, which is thicker than the width of the robotic arm, and are embedded at the front and rear ends of the robotic arm.
If you cut off any end and look at it, the appearance is somewhat similar to the famous rotary machine gun - the main body of the machine gun is the mechanical arm, and the measurement module is the bullet disc.
These measurement modules have been preset with very fine measurement components, and they have been uniformly tested during the previous handover process without any flaws.
Therefore, Xu Yun and the others do not need to operate the inside of the module, they only need to install the container containing Pangu particles and the module.
For example, the previous embedded disc, and the current docking connection.
The yellow wire on his hand is connected to the laser alignment instrument - this thing is called a meter, but it is actually about 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
Xu Yun carefully proofread the structure diagram:
"Found it, sensor A3 interface."
Click——
The cable went into place smoothly.
In addition to Xu Yun, others are also seriously assembling several other modules.
for example
The refrigeration link required to ensure low temperature.
"Hoho, this thing can achieve a cooling effect of 50nK?"
In the warehouse.
Looking at the refrigeration module that was only half the size of a microwave oven in front of him, the youngest Liang Haoran couldn't help but raise 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 class, they were fellow villagers from the same place. They had always had a good relationship, and they were in a conjugated father-son relationship.
When Tang Fei heard this, he rolled his eyes at him and gave him the middle finger without mercy:
"Lulu, laser cooling and magnetic potential well evaporative cooling equipment, the effect is infinitely close to absolute zero. Looking at this performance, you can tell that it is not cheap. Where did you get the courage to ask the price?"
Liang Haoran seemed very optimistic and didn't care at all about his friends' contempt:
"Why don't you just tell me a price and 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 there are no more than ten units in the country."
"Of course, this is not because the old-fashioned technology is immature, but because it is rare to need to use this kind of temperature outdoors."
"But if our trial run is successful, people in this business will probably have big orders."
"hiss"
Liang Haoran suddenly took a deep breath of air conditioning, looked at the refrigeration module in front of him again, and smacked his lips:
"Such a thing costs three million?"
Tang Fei snorted coldly and said nothing.
But soon, Liang Haoran thought of another question, and asked Tang Fei slyly:
"Hey, Old Tang, no matter how expensive this thing is, it's only equivalent to a refrigerator - so can it talk dirty words?"
Tang Fei:
".?"
Yes, he is another person who plays with the heart of the atom and plays with the devil.
Huh.
Why say again?
The connection between the refrigeration module and the container is an important part of the entire assembly process.
But still the same sentence.
The words importance and difficulty are actually 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 at all levels during production.
Just like a mushroom bomb, you can light a lighter next to it for a hundred hours without any problems.
So it's quick.
More than an hour later.
As the time approached ten o'clock in the morning, a complete gravity gradiometer finally appeared in front of everyone.
This instrument is completely black and its height is about two-thirds of an adult, which is about one Pandora.
At the bottom of the instrument is a metal base ten centimeters thick and about one meter in diameter.
Although this support is inconspicuous, it is actually the information transmission center of the gravity gradiometer, with 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 fisherman.
Above the support is a cylinder with a height of about fifty centimeters. Inside the cylinder are the container containing Pangu particles and the cooling module, the external lattice plate, the three-dimensional electrostatic balance equipment designed by Huang Yuting, etc.
Above the column is a hemispherical cover with the opening facing upward.
There is a vertical signal receiver inside the cover, and three robotic arms are attached to the inner wall of the cover.
If this description is not easy to understand, you can imagine this picture:
There is a can of Wong Lo Kat on a plate of mosquito repellent incense. There is a small bowl on top of Wong Lao Kat. There is a stick of Green Arrow chewing gum standing in the center of the bowl. The inner wall is smeared with ketchup from the mouth to the bottom of the bowl in three directions.
The mosquito coil is the base, Wong Lo Kat is the cylinder, the small bowl is the cover - and the three strips of tomato sauce are the three inner walls attached to it.
After the gravity gradiometer is assembled.
Li Hua and Ge Tongyou powered it on first, and the instrument quickly started buzzing—this meant that the basic power supply line was normal.
See this situation.
Li Hua waved to the assistant again:
"Xiao Guo, take out your things."
