"Yes."

"Then I'll go back now and ask for you. You have to study too, time is precious." Li Chengzhi picked up his phone, took a photo of the seismograph, and left.

After Li Chengzhi left, Chen Mo continued to transform the seismograph.

Installing instruments on the seabed is not as simple as adding a waterproof layer. It needs to overcome the two biggest difficulties, the water pressure and signal on the seabed thousands of meters away.

These two problems must be solved. If the water pressure is not overcome, it will not work normally or even break down.If the communication problem is not solved, even if the installation is complete, if there is no signal to communicate with the outside world, the early warning message of the seismograph cannot be sent out.

The structural transformation of the seismograph is another problem, but thanks to the existence of Mo Nu, the trouble is much less.

Chapter 142 Wu Zhen's Wish

Institute of Geography, Academy of Sciences.

Wu Zhen carefully read the paper in his hand, which was published by Chen Mo on earthquake early warning research.

He has researched back and forth no less than five times, and did some simple experiments to find evidence for this thesis, but the results were not satisfactory.

Although the experiment is not ideal, as time goes by, he now looks at this paper, and it seems that he has a new understanding, and the more he reads it, the more interesting it is.

He has been engaged in geological and geographical research for more than 30 years.

At the moment when he lost his family members in the earthquake, he vowed in his heart that he hoped that in his lifetime, he could solve the problem of early warning of earthquakes, or he could use his own ability to save more people during the earthquake.

Many earthquake rescue instruments and equipment, and instruments for measuring the earthquake resistance of houses and bridges are all made by him.He also participated in the formulation of the seismic standards for houses issued by the Earthquake Administration, and he is considered an expert.

When Chen Mo's thesis came out, it successfully attracted his attention, but he didn't come out to show his presence.

As some experts who spoke out said, science is a rigorous discipline, and they have no experiments to prove that Chen Mo's theory is wrong. It is very undesirable to veto Chen Mo with empty words.

He studied this paper several times, but he always felt that the most critical point was missing, which made him feel like he was scratching his head.

It may be that Chen Mo missed some important point, which made him unable to find the essence of this paper.While Wu Zhen was looking at the paper, Li Chengzhi entered his office led by an assistant.

Li Chengzhi knocked on the door and interrupted Wu Zhen who was reading the paper: "Mr. Wu, hello."

"You are?" Wu Zhen looked at Li Chengzhi suspiciously.

"My name is Li Chengzhi, and this is my ID." Li Chengzhi took out his ID and handed it to Wu Zhen: "I came here because I want to talk to you about something."

Wu Zhen looked at the certificate, and looked at Li Chengzhi in surprise: "Sit! Comrade Li, what do you want from me?"

"I heard that Mr. Wu was studying Chen Mo's thesis recently, and I happened to have something about Chen Mo here, so I came to see you." Li Chengzhi said with a smile.

"Oh? What about him?" Wu Zhen asked.

"Look at this." Li Chengzhi handed the photo taken from Chen Mo's laboratory to Wu Zhen: "I just came back from Binhai City. This is an instrument made by Chen Mo. He said it was made using the principles of the paper, called Seismograph."

The last sentence immediately aroused Wu Zhen's interest. He took the photo and looked at it carefully.

"Did he really say that?"

"Indeed." Li Chengzhi said, "He is going to put this instrument in the Mariana area for data collection. Aren't you going to conduct a marine geological survey? That's why I came to you."

"Can you show me this instrument?" Wu Zhen asked.

……

Chen Mo is outside the building of the Marching Army Ant Company. He is also accompanied by Xiao Yu, Li Lingfeng and others. Zhao Min is already on a business trip.

The second day after Li Chengzhi went back, he called and told him that an expert in seismology wanted to come and have a look at the seismograph.There is no way to refuse this matter, after all, this instrument is what they will take out to sea in the future.

After a while, Wang Hai entered the company in the car that was going to pick him up. When he saw Li Chengzhi and a teacher with plain clothes and gray hair get out of the car, Chen Mo and others greeted him.

"Chen Mo, this is Mr. Wu Zhen from the Academy of Sciences, who has been engaged in seismological research for more than [-] years." Li Chengzhi introduced to Chen Mo.

"Mr. Wu." Chen Mo hurriedly saluted.As a junior student, these etiquettes are necessary.

"Hey, hello, you're welcome, a real person is better than a photo." Wu Zhen held Chen Mo's hand and smiled.It's been a long time since I saw such an outstanding junior.

"Mr. Wu, let's talk with the students inside first." Chen Mo said.

"No, just take me to see that instrument, your time is more precious than mine, so don't waste it," Wu Zhen said.

"Ok."

Chen Mo could see Mr. Wu Zhen's eagerness to see the seismograph.

After the group entered the Marching Army Ant Company, they went straight to Chen Mo's laboratory.There are only four people who can enter Chen Mo's experimental area.

"I've studied your thesis five times and done a few simple experiments, but I always feel that something is missing and I can't grasp the most important point." Wu Zhen opened his mouth as he walked.

"Because I was afraid that the technology would be passed on, I didn't write out the core part. Otherwise, if the technology leaks to foreign countries, the loss will be great." Chen Mo said.

"Yes." Wu Zhen nodded.

Not long after, a group of four entered the laboratory.

In the laboratory, it was the same as when Li Chengzhi came last time, except for the most conspicuous seismograph and a few robots, nothing else was exposed.

After seeing the seismograph, Wu Zhen walked over cautiously, without touching the seismograph with his palm, but observed carefully around the seismograph.

"Mr. Wu seems to be very concerned about the seismograph."

Chen Mo didn't bother him, the seismograph looked from the outside and couldn't tell why.

"The earthquake more than [-] years ago took away his relatives. Over the years, Mr. Wu has been devoting himself to the research of disaster relief equipment. He is almost paranoid about these instruments. He changed his name to Wu Zhen back then, which means earthquake It was changed later." Li Chengzhi whispered in Chen Mo's ear.

Hearing these words, Chen Mo was in awe.It is the almost paranoid pursuit of the older generation of scientists to focus on one field for decades, which leads to their current stable life.

"Have you tried this instrument?" After carefully looking around the seismograph, Wu Zhen stopped.

"The shock wave test has been done, but it is a simple simulation test, and the instrument can be operated. Now we are preparing for the field test, setting up several test stations in the Tibetan area, and sending a few to the West Pacific, where the land and ocean environments are tested together. Time." Chen Mo said.

"How much is it?" Wu Zhen asked.

"Not much. Money is not a problem. The sooner the test is completed, the sooner it is put into use if it is really feasible. It will be good news for many people." Chen Mo said.

"Yes." Wu Zhen looked at Chen Mo with admiration, then turned his gaze to the seismograph, hesitant to speak.

"Mr. Wu, if you have anything to say, just say it." Chen Mo said.

"I'm still not sure if this instrument is useful. If it is, can you provide me with a copy of the collected data." Wu Zhen said after a moment of hesitation.

"Of course, I can't do it alone for such a big matter. I'm also planning to cooperate with Binhai University. It's my wish to have you join me." Chen Mo laughed.

He is currently short of maintenance personnel in this area. Wu Zhen has been engaged in it for decades and is a senior academician.There are definitely no longer a small number of students, and there are a lot of network resources on him, which can save a lot of trouble.

It's just the collected data, which is very simple, and it's not the manufacturing technology of a seismograph.

After receiving Chen Mo's answer, Wu Zhen smiled.

He didn't have much hope for this instrument, but even if it was a ten-thousandth hope, he would seize it.If true, this seismograph will fulfill his lifelong wish.

Things went smoothly, and Wu Zhen also agreed to do his best to help Chen Mo carry out this experiment.After getting an affirmative answer, the next thing for Chen Mo is to modify the seismograph and put it into the seabed.

Chapter 143 Installation

Short waves are easy to attenuate in water. If you want to send signals on the seabed, you must use ultra-long waves or extremely long waves for communication. This is the direction of signal transformation of submarine seismographs.

As for the problem of seabed water pressure, the seismograph must be structurally modified to adapt to the strong water pressure on the seabed. Otherwise, whether the instrument can work normally under such terrifying water pressure is a big problem.

Mo Nu helped to optimize the structure of the seismograph, and Chen Mo also entered the science and technology library and took a set of extremely long wave communication technology.Extremely long wave communication technology is one-way, can only transmit, cannot receive signals, and is generally used in submarine communication.

But with the current conditions, being able to send signals hundreds of meters or even thousands of meters under the sea is already very remarkable.It is also necessary to install a buoy-type antenna outside the seismograph.

With the help of artificial intelligence and technology libraries, and the full support of the Army Ant Company, the transformation of the seismograph went smoothly.

Now that the seismograph has been released, Chen Mo has devoted all his energy to the manufacture of the seismograph.In order to be able to make all the required seismographs before the ocean scientific expedition of the Academy of Sciences.

The scientific expedition team on land is in cooperation with Binhai University, jointly with professors and students to enter Tibetan areas.Everything is in full swing.

The turmoil of the thesis has passed, there has been no big news for a long time, and now no one pays attention to Marching Ant Company, and the media's attention has turned to other places.In addition, the actions of the Army Ant Company are kept secret, so outsiders do not know what big moves the Army Ant Company has.

At Binhai Wharf, as the last huge box was loaded onto the boat, Chen Mo let out a sigh of relief.For two months, he had been preparing every moment for this day, and now it was finally here.

"There is a tutorial video on the installation of the seismograph. It's very simple. You hand it over to Mr. Wu Zhen." Chen Mo took out a USB flash drive and handed it to Li Chengzhi.

Li Chengzhi took the USB flash drive and put it away, and took a deep look at Chen Mo.This time, Chen Mo's application for this project went surprisingly smoothly. Maybe the higher-ups wanted to see if Chen Mo could create miracles.

He is not worried that these instruments will be snatched away by other countries. He asked Chen Mo this question, and Chen Mo also told him that he was already prepared.

Once it starts, if you want to pick it up again, you must command to stop running, otherwise it will start the self-destruct function.

Such a large device is placed there. When sending a signal, once other countries discover the existence of the signal, they will definitely find a way to retrieve it.

There are many coveted technologies in it.

In order not to leak the technology and pick it up without terminating the operation, the seismometer will be opened on the seabed and self-destruct with the help of strong water pressure.

The seismograph has been transformed into a semi-intelligent machine by Chen Mo. If he is given a little more time, he doesn't mind transforming the seismograph into a robot that can move by itself. It will be difficult to pick it up when the time comes.

After bidding farewell to Chen Mo, Li Chengzhi boarded the ship and left, sending the equipment to the ship of the scientific expedition team.

"Is the instrument really okay?" On the way back, Xiao Yu looked at Chen Mo who was beside him.

"Don't worry, even if they directly throw the instrument into the sea, it will start by itself after it sinks to the seabed, it's just a matter of location. Mr. Wu is an expert in earthquakes, and he knows which location is the most suitable to install, so it's better, no There will be too many problems." Chen Mo said confidently.

"That's good, now the matter is over." Xiao Yu said: "You have been busy for two months, take two days off."

"The seismograph sent to the Tibetan area should have arrived. They should be able to do the installation. Now that the work has come to an end, we are ready to enter the next stage. I will accompany you these two days, relax, and go wherever you want. "

"I want to go to the movies." Xiao Yu smiled and said, "You haven't watched a movie with me for a long time."

"That's all you have to offer." Chen Mo was amused by Xiao Yu, only in front of him, Xiao Yu would show her side of a little woman.

"That's what I'm supposed to do." Xiao Yu said confidently.

Tibetan area.

Zhang Songlin was amazed as he touched the two-meter-high cylindrical instrument.

He is a professor at the School of Geographical Sciences, Binhai University, and has research in geology.This time, the Army Ant Company cooperated with Binhai University, and he happened to have a geological survey to come to Tibet, so he was sent here.

This time his investigation project was also sponsored by the Army Ant Company.

Their task this time is to install ten seismometers in ten locations.Regarding the formalities, Marching Army Ant Company has negotiated with the Tibetan government, and there is no problem.

He is a professor of geology. The geology of this place, he knows very well, is above the fault.

The sudden movement of the crustal fault blocks along the faults is the main cause of earthquakes, especially near the junction of the plates, the crust is active, and this area is one of the most earthquake-intensive places in China.

Scientists have been studying these faults. As long as the research on the fault mechanism is in-depth, earthquakes can be accurately predicted. Now the army ant company is doing this.

Back then, when Chen Mo published that paper, he didn't believe it either, but he didn't expect to come to help Marching Army Ant Company now.

"Professor Zhang, the drill hole has been drilled." When Zhang Songlin was lamenting the achievements of Marching Army Ant Company, a worker wearing a hard hat came over and interrupted his thoughts.

Zhang Songlin reacted and patted the seismograph by his hand: "Transport the instrument to the top of the borehole and prepare for installation."

This is a confidential project. He dare not say that this is the seismograph of the Marching Ant Company. These things are only known to those who should know.

As soon as Zhang Songlin's words fell, several workers carried the seismograph and walked to the top of the hollow.

"Turn one step clockwise to align the three holes below." As soon as several workers lifted the instrument to the hole, a staff member responsible for checking the position spoke.

After 2 minutes, the holes are aligned.

After connecting the circuit, Zhang Songlin opened the slot of the instrument, followed the tutorial he had read, and pressed the start button.

hum!

The sound of mechanical operation sounded, and the three closed holes under the seismograph suddenly opened, and three probes slowly protruded out and entered the underground borehole.

As soon as the probe stopped, Zhang Songlin opened the top of the instrument, and the geomagnetic field detector composed of coils rose up and exposed to the air.The appearance of the seismograph is not flattering, but Zhang Songlin still debugs it according to the steps.

After debugging, Zhang Songlin took out his computer and began to receive information from the seismograph.

At another location, Luo Changhua is also doing the same installation work.They have to install ten machines, and install them in two ways, so that the work efficiency is higher.

The installation of seismographs in Tibetan areas is progressing steadily.

maritime,

After the six large boxes were sent to the scientific research ship, a group of experts immediately surrounded the boxes, led by Wu Zhen.

Quite a few people were curious about what they were asked to express this time.

Their scientific expedition included projects on marine biology, marine chemistry, marine physics, and marine geology. The first destination was the Mariana Trench.
