Chapter 857 Eye of the Earth

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

That is, the personnel responsible for technical issues of the three companies were brought together to explain the current pre-research situation, design goals and subsequent work task allocation of the LNG ship project.

According to the original plan, although Chang Haonan did not participate in the project in person, he was still prepared to listen to this seminar and return to Beijing in a few days-

Firstly, this was the first time that Lei Zhixing and Liu Fangping took such a big job alone without anyone to lead them.

Secondly, this was also the first time that the state monitoring and fault automatic diagnosis system he developed was put into a specific application scenario.

However, plans cannot keep up with changes.

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

Comrades from the Huaxia Geological Survey Bureau have completed the first three groups of geological surveys and brought the samples back to Beijing.

Currently, the analysis and testing of basic projects are underway.

So, after thinking again and again, Chang Haonan decided to terminate his trip to Shanghai in advance.

…

Two days later.

Huaxia Academy of Sciences, Institute of Geology and Geophysics.

When Chang Haonan returned to Beijing to take a short break and then rushed here, Meng Zhenyuan and Li Nianheng had been waiting in a conference room for a while.

In addition to them, there were more than a dozen technicians from the Geological Survey Bureau and the Institute.

"Hello, Professor Chang."

Seeing Chang Haonan walk in, a middle-aged man sitting at the first seat on 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 all aspects."

As he spoke, 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 cooperation of this level, the other side will generally send an academician to take charge.

Even if they are not responsible for specific work, they can play a role in striving for resources.

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

But looking at the situation in front of him, 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 an academician yet, he no longer needs to rely on other people's names to fight for resources...

"Since it is a cooperative research, it is natural to cooperate with each other."

After Chang Haonan sat down, he exchanged a few polite words with the other party.

Then he got to the point.

A representative from the Geological Survey Bureau 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 the Alxa region in western Inner Mongolia. I am Xiao Wenchang. Let me briefly introduce our exploration mission..."

"Due to the problems of manpower, equipment and funds, according to the requirements of Professor Chang and Chief Engineer Li, we first conducted exploration in 3 groups and 9 target areas in the Loess Plateau area in the east of Longyuan, the desert area in Alxa in western Inner Mongolia, and the perennial snow and modern glacier action zone in the northern foothills of Tianshan Mountain, with a total of 413 detailed points..."

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

But it is an image with a very small scale after all, so each "point" reflected in the map is actually a task area for the exploration mission.

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 at the beginning of the year to now, the entire exploration team has been exposed to the wind and sun in the wild for almost half a year.

This can be seen from Xiao Wenchang's skin color -

The exposed parts such as face, hands and neck are completely different from the arms.

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

Therefore, after he finished explaining the exploration mission, the whole audience almost immediately responded with warm applause.

"The next part is the result of our on-site analysis of the samples from the exploration points."

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

"First, the Alxa region I am responsible for, a total of two areas, 80 exploration points."

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

There are two marks not far apart there.

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

"Due to weathering, the two deserts have no obvious differences in characteristics at the surface, that is, within a depth of 0.5-2 meters. However, at deeper locations, especially above 3 meters, we observed obvious differences in the moisture stratification of the two areas."

"In addition, thanks to the guidance of remote sensing satellite images, we are fortunate to have discovered an ancient river channel system in the southeast of the Tengger Desert that has never been paid attention to in the past. It is also an unexpected gain..."

Xiao Wenchang 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 brand new work experience.

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

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

It may not look very big on the map, but if you really want to send people in, then different locations, different depths and different sampling methods, a full set of half a year is considered extremely efficient.

If you encounter a hard bone, it is common to do it for two or three years or even longer.

This does not count the risks to be paid in the process.

And after a lot of operations, it is likely that nothing is found, which is a waste of time.

At most, a few papers can be published.

To obtain some truly meaningful results, it often takes several or even more than a dozen rounds of exploration.

It basically spans a person's career.

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

Although the difficulty of the exploration process itself has not changed, it can really produce results.

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

If he can continue to maintain this efficiency in the future, Xiao Wenchang feels...

Considering that he still has about ten years before he can no longer work and retires to the second line, the academician seems to be waving to him...

"..."

"In short, we preliminarily speculate that it may be due to the difference in water content stratification, which causes the polarization SAR signal to have different degrees of scattering and refraction in the process of penetrating the sand layer, so different signal responses are presented on the satellite map..."

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

And Li Nianheng, who had not spoken just now, suddenly interrupted at this time:

"Team leader Xiao, please wait a moment, I have a question."

Because this is a normal academic exchange meeting, not a project defense, it is not necessary to wait for everyone on the stage to finish speaking before asking questions.

"Although different moisture stratification conditions do affect the results of SAR detection, if this is the only reason, then we should be able to analyze it directly even with conventional methods."

"But the actual situation is that our first round of analysis did not reflect any difference between the two areas. It was not until Professor Chang used a new calculation method to process it that he found that the feedback signals of the two areas were significantly different."

"So, I'm afraid there are deeper reasons..."
