The Military-industrial Scientific Research System of the Academic Master Chapter 857

Chapter 857 Eye of the Earth

After the signing ceremony of the tripartite cooperation, the Hudong Factory arranged a series of project seminars in the following days.

That is to say, the personnel responsible for technical issues from the three companies are brought together to explain in detail the current pre-research status, design goals and subsequent work task allocation of the LNG ship project.

According to the original plan, although Chang Haonan did not personally participate in the project, he still planned to attend the seminar and return to the capital in a few days—

First of all, this is the first time that Lei Zhixing and Liu Fangping have taken on such a big job alone without anyone to take care of them.

Secondly, this is also the first time that the condition monitoring and automatic fault diagnosis system he developed has been put into specific application scenarios.

However, plans cannot keep up with changes.

Just after the first seminar, he received a call from Professor Meng Zhenyuan in the afternoon of the next day.

Comrades from the Huaxia Geological Survey have completed the first three sets of geological survey and brought the obtained samples back to the capital.

At present, analysis and testing of basic projects are underway.

So, after much thought, Chang Haonan decided to terminate his trip to Shanghai in advance.

Two days later.

Institute of Geology and Geophysics, Chinese Academy of Sciences.

When Chang Haonan returned to the capital for a short rest and then rushed here, Meng Zhenyuan and Li Nianheng had been waiting in a conference room for some time.

In addition to them, there are also more than a dozen technical staff from the Geological Survey and the institute.

“Hello, Professor Chang.”

Seeing Chang Haonan walk in, a middle-aged man sitting at the head of the left side of the conference table immediately stood up, shook hands with the former, and then introduced himself:

“I am Zhai Mingguo, a researcher at the Institute of Geology and Geophysics. I mainly study metamorphic geology, tectonic evolution and igneous petrology. I am responsible for presiding over the analysis of the results of this exploration. Of course, I will also cooperate with your work in an all-round way.”

While speaking, he had already led Chang Haonan to the main seat at the conference table.

Chang Haonan was slightly surprised by Zhai Mingguo's statement.

After all, generally speaking, for this level of cooperation, an academician will usually be assigned to the other side.

Even if you are not responsible for specific work, you can still play some role in securing resources.

At the same time, it can also prevent the unit from being squeezed out or marginalized.

But looking at the posture in front of me, it seems that there is no such person.

Otherwise, a researcher would not be allowed to take the lead.

But this is not a bad thing for Chang Haonan.

After all, although he is not yet an academician, he no longer needs to rely on other people's names to secure resources...

“Since it is a collaborative research, it is natural to cooperate with each other.”

After Chang Haonan sat down, he said a few more polite words to the other party.

Then we got to the point.

A representative from the Geological Survey first walked to the small podium at the other end of the conference room.

A PPT was quickly projected on the screen.

“Comrades, I am the deputy leader of this round of geological exploration team, and also the leader and person in charge of the exploration mission in Alxa area in western Mongolia Province, Xiao Wenchang. Let me briefly introduce our exploration mission...”

"Due to problems with manpower, equipment and funds, according to the requirements of Professor Chang and Engineer Li, we first conducted research on the Loess Plateau area in eastern Longyuan, the desert area in Alxa in western Mongolia, and the perennial snow and ice at the northern foot of the Tianshan Mountains. The modern glaciation zone has been explored in 3 groups, 9 target areas, and a total of 413 detailed points..."

On the remote sensing satellite image that underwent data dimensionality reduction, a total of nearly 80 abnormal points were counted.

But that is a very small-scale image after all, so each "point" reflected on the map is actually a task area for the exploration task.

In each area, dozens or hundreds of exploration points must be determined, and hundreds or even thousands of exploration operations must be carried out.

Therefore, it is indeed quite difficult to take care of 9 areas with 3 types of terrain features at one time.

From February of the beginning of the year until now for half a year, the entire exploration team has been exposed to wind and sun in the wild almost all the time.

This can be seen from Xiao Wenchang's skin color - the exposed parts of his face, hands and neck are completely different colors from his arms.

The situation of the other two team leaders in the conference room was basically the same.

Therefore, after his explanation of the exploration mission came to an end, the audience almost immediately burst into warm applause.

“The following part is the result of our on-site analysis of the samples from the exploration site.”

When the applause gradually faded, Xiao Wenchang calmed down a little and then continued:

“The first is the Alxa area that I am responsible for, with a total of two areas and 80 exploration sites.”

At the same time, the screen switched to the map that Chang Haonan was so familiar with, and then zoomed in to the westernmost location of Mongolia Province.

There are two markers not far apart.

“Based on the results provided by remote sensing satellites, we conducted multi-point surveys from the outside to the inside of the Badain Jaran and Tengger Deserts. The specific results are as follows…”

"Due to the existence of weathering, there is no obvious difference in characteristics between the two deserts at the surface, that is, within the depth of 0.5-2 meters. However, at deeper locations, especially above 3 meters, we observed that the two deserts have different characteristics. There are obvious differences in the moisture stratification of each area.”

“In addition, thanks to the guidance of remote sensing satellite images, we were fortunate enough to discover an ancient river system in the southeastern part of the Tengger Desert that we have never paid attention to before, which is also an unexpected gain..."

Xiao Wenchang's tone on the stage gradually became excited.

For an old guy like him who has been in the industry for more than 20 years, this mission definitely brought a new work experience.

In the past, geological exploration was largely a matter of luck.

Because this kind of work is a three-dimensional work.

It may not look like a big place on the map, but if you really want to send people in, then with different locations, different depths and different sampling methods, a complete set can be considered extremely efficient in half a year.

If you encounter some difficult bones to crack, it is common for you to work on it for two to three years or even longer.

This does not include the risks involved in the process.

And after a quick operation, there is a high probability that nothing will be discovered, and it will be in vain.

Send at most a few papers for submission.

To obtain some truly meaningful results, it often takes several or even dozens of rounds of exploration.

Basically runs through a person's career.

But this time, he experienced what it means to be targeted.

While the exploration process itself remains arduous, it does pay off.

He was given several target areas above, and after a round of exploration, he discovered a lot of new things...

If this efficiency can be maintained in the future, then Xiao Wenchang feels...

Considering that I still have about ten years before I can no longer do anything and retreat to the second line, the academician seems to be waving to me...

"In short, we preliminarily speculate that it may be due to differences in water content stratification that the polarimetric SAR signal undergoes different degrees of scattering and refraction during the process of penetrating the sand layer, so it appears differently on the satellite image. Signal response…”

At this point, Xiao Wenchang paused for a moment, picked up the cup on the podium and prepared to take a sip of water.

Li Nianheng, who had been silent just now, suddenly intervened:

“Leader Xiao, please wait a moment, I have a question.”

Because this is a normal academic exchange meeting, not a project defense, there is no need to wait for everyone on the stage to finish speaking before focusing on asking questions.

“Although different moisture stratification conditions will indeed affect the results of SAR detection, if this is the only reason, then we should be able to analyze it directly even using conventional methods.”

“The actual situation is that the first round of analysis we conducted did not show any difference between the two areas. It was not until Professor Chang processed it with a new calculation method that we discovered that there was a significant difference in the feedback signals from the two areas. "

“So, I'm afraid there are deeper reasons…”
