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 to bring together the personnel in charge of technical issues from the three companies to explain in detail the current preliminary 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 sit in on the seminar and return to Beijing in a few days.
Firstly, this was the first time that Lei Zhixing and Liu Fangping took on such a big job alone without anyone to guide them.
Secondly, this is also the first time that the condition monitoring and automatic fault diagnosis system he developed has been put into a specific application scenario.
However, plans cannot keep up with changes.
Just after the first seminar ended, the next afternoon, he received a call from Professor Meng Zhenyuan.
Comrades from the China Geological Survey have completed the first three sets of geological surveys and brought the samples obtained back to the capital.
Analytical testing of basic projects is currently underway.
So, after much deliberation, Chang Haonan decided to cancel his trip to Shanghai early.
……
Two days later.
Institute of Geology and Geophysics, Chinese Academy of Sciences.
When Chang Haonan returned to Beijing 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 more than a dozen technicians from the Geological Survey 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'm Zhai Mingguo, a researcher at the Institute of Geology and Geophysics. I mainly study metamorphic geology, tectonic evolution, and igneous petrology. I'm responsible for the analysis of the results of this exploration. Of course, I'm also cooperating with you in all aspects of your work."
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 party will usually send an academician to take charge.
Even if you are not responsible for specific work, you can still play a role in obtaining resources.
At the same time, it can also prevent the unit from being excluded or marginalized.
But looking at the situation in front of me, it seems that there is no such person.
Otherwise, a researcher would not be asked 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 gain resources...
"Since this is a collaborative research, it is natural for us to cooperate with each other."
After Chang Haonan sat down, he exchanged a few polite words with the other party.
Then we got to the point.
A representative from the Geological Survey first walked up to a small podium at the other end of the room.
A PPT was quickly projected onto 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 problems with manpower, equipment and funding, we first conducted exploration in three groups of nine target areas, a total of 3 detailed points, in accordance with the requirements of Professor Chang and Chief Engineer Li, in the Loess Plateau area in the east of Longyuan, the desert area of Alxa in the west of Inner Mongolia, and the perennial snow and modern glacier action zone in the northern foothills of the Tianshan Mountains..."
A total of nearly 80 abnormal points were counted on the remote sensing satellite image that had undergone data dimensionality reduction processing.
But after all, it is an image with a very small scale, so each "point" shown on the map is actually a mission area for the exploration mission.
In each area, dozens or hundreds of exploration points must be identified and hundreds or even thousands of exploration operations must be carried out.
Therefore, it is indeed quite difficult to take care of nine areas with three types of terrain features at one time.
From February at the beginning of the year until now, for half a year, the entire exploration team has been almost always working in the wild in the wind and sun.
This can be seen from Xiao Wenchang's skin color.
Exposed areas such as the face, hands and neck are completely different colors from the arms.
The situation of the other two team leaders in the conference room was basically the same.
Therefore, when he finished explaining the exploration mission, the whole audience almost immediately broke into applause.
“The next part is the results of our on-site analysis of samples from the exploration sites.”
Until the applause gradually faded, Xiao Wenchang calmed down a little before continuing:
"First, the Alxa region that I am responsible for has two areas and 80 exploration points."
At the same time, the screen switched to the map that Chang Haonan was very familiar with, and then zoomed in to the westernmost location of Meng Province.
There are two markers not far apart.
"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 do not have 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 were fortunate to discover an ancient river system in the southeast of the Tengger Desert that had never been noticed before. This was 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 brand new work experience.
In the past, geological exploration was largely a matter of chance.
Because this kind of work is a three-dimensional job.
It may not look like a big place on the map, but if you really want to send people in, you need to use different sampling methods at different locations, depths and depths. It would be extremely efficient to complete the whole set in half a year.
If the problem is a bit tough, it is common to take two to three years or even longer.
This does not include the risks involved in the process.
And after all the operations, there is a high probability that nothing is found and it is a waste of time.
At most, just publish a few papers to get the job done.
In order to obtain some truly meaningful results, it often takes several or even dozens of rounds of exploration.
It basically spans a person's career.
But this time, he experienced what it meant to be well-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 discovered a lot of new things...
If this efficiency can be maintained in the future, Xiao Wenchang feels...
Considering that I still have about ten years before I can no longer work and have to retire to the second line, it seems that the academician is already waving to me...
"..."
"In short, we preliminarily speculate that it may be due to the difference in water content stratification that the polarization SAR signal is scattered and refracted to different degrees when penetrating the sand layer, so different signal responses are presented on the satellite image..."
Having said that, Xiao Wenchang paused for a moment, picked up the cup on the podium and prepared to drink some water.
Li Nianheng, who had been silent just now, suddenly interrupted:
"Team Leader Xiao, please wait a moment. I have a question."
Because this is a normal academic exchange meeting rather than a project defense, you don't necessarily need 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 reality is that our first round of analysis did not show any difference between the two areas. It was not until Professor Chang used a new computational method that we found that there was a clear difference in the signals they fed back."
"So, I'm afraid there are deeper reasons..."
