"In that case, I won't disturb Professor Wang and Yu Gong. I'll come back when I get off work."
Li Li was an office administrator and didn't know much about instruments. Upon seeing this, she got up and left.
After Li Li left, Professor Wang began to introduce the plasma spectrometer.
Professor Wang is indeed a professor who has done a lot of in-depth research on instrument analysis. From time to time, more cutting-edge professional terms pop up in his mouth. Professor Wang does not elaborate on these more cutting-edge professional terms. First of all, these terms are very important to him.
Because the words are very commonplace, I disdain and explain too much. In addition, there is also the common problem of literati "showing off" in it.
The former Yu Ziqing, who had just graduated less than a year ago, would probably have only half-understood knowledge and would not be able to keep up with Professor Wang's lectures. But now Yu Ziqing not only has incomparable wisdom and memory, but also has been in the past few months.
When he has nothing to do, he surfs the technology Internet every day. Professor Wang's lectures seem concise and concise to his ears, without any unnecessary nonsense, and he is quite teachable.
Professor Wang showed off a little, but when Yu Ziqing remained silent and nodded repeatedly, it seemed that he was a professor who had no meaning and could not say anything profound.
"Xiao Yu, if there is anything you don't understand, please ask as many questions as possible. Don't be embarrassed." Halfway through the lecture, Professor Wang finally couldn't help but say.
"Teacher Wang explained very thoroughly, I understand clearly." Yu Ziqing replied with a smile.
Professor Wang was a little unhappy when he heard this. He thought to himself, many of the things I am talking about now cannot even be understood by those with master's degrees and Ph.D.s who have already started working and training here. You, an undergraduate who has just graduated one year ago, are talking nonsense.
, I really don’t know how to pretend to understand, and it’s extremely exaggerated.
"Oh, the most commonly used detectors in full-spectrum direct-reading plasma spectrometers are CCD and CID. Leeman uses CID. So can you tell me the advantages and disadvantages of CID and CCD?"
Professor Wang asked somewhat unhappily.
Yu Ziqing nodded and replied calmly: "The charge-coupled device CCD is... But there is a charge overflow phenomenon in local CCDs. Generally, signal processing circuits are relied on to solve the overflow problem of the detector, which is a destructive readout. The charge injection device CID is...
...It is a non-destructive readout, but the quantum efficiency, dark current level, and reading noise are not as good as CCD. Regarding the shortcomings of CCD destructive readout, segmented coupling can be used to improve..."
Yu Ziqing not only clearly explained and analyzed the working principles, advantages and disadvantages of the two detectors, but also put forward suggestions for improvements and solutions to these shortcomings in current cutting-edge research papers.
After hearing this, Professor Wang was greatly surprised. He immediately looked at Yu Ziqing, an undergraduate who had just graduated a year ago, with admiration. He nodded and praised, "Well, that's a very good lecture. Nowadays, few people who do analysis understand the principles of instruments."
So thoroughly eaten."
Yu Ziqing smiled lightly and did not show even a little bit of complacency because of Professor Wang's praise. This made Professor Wang appreciate Yu Ziqing even more, and unconsciously began to look at him as a peer.
Next, Professor Wang talked about some knowledge about the optical principles of instruments. Seeing that Yu Ziqing basically understood it, he stopped going into details and asked Yu Ziqing to directly follow his master student Xiao Bi to operate the machine.
An afternoon is neither long nor short, but for Yu Ziqing, who has solid theoretical knowledge and strong hands-on understanding ability, it is enough for him to master the basic operations of a plasma spectrometer, even spectral line interference, selection,
Instrument optimization Yu Ziqing has been able to put forward some correct opinions.
This made Xiao Bi, who took Yu Ziqing on the plane, very embarrassed. In the end, he was quite restrained, fearing that he would make Yu Ziqing laugh if he gave the wrong advice.
Professor Wang also came here two or three times during this period. Every time he saw Yu Ziqing skillfully helping Xiao Bi test samples while Xiao Bi was doing nothing, he was surprised. He really suspected that Yu Ziqing had used a plasma spectrometer before.
"Xiao Yu, I think there will be another day of computer training tomorrow, and you can move around freely." When Professor Wang made his last trip to see the progress of the work here, he saw Yu Ziqing skillfully selecting spectral lines and subtracting backgrounds, and couldn't help but take pictures.
He patted Yu Ziqing on the shoulder and said.
Yu Ziqing turned around and smiled and said: "Playing is not important, you can do it anytime, but it is not easy to come to your place. You have many high-end instruments here. If you don't mind, I would like to follow and learn everything.
"
"You young man is quite ambitious. Okay, as long as you want to learn, you can just follow my students. They can just relax with you and enjoy the teacher's addiction." Professor Wang admired Yu Ziqing's desire to make progress.
The young man readily agreed.
"Then I really want to thank you. I'll treat you and this classmate Bi to dinner tonight." Yu Ziqing smiled and patted Xiao Bi on the shoulder and said.
Although Yu Ziqing looks like a college student at a young age, his every move is so natural and without any formality, as if he is not facing a professor from Tsinghua University, but an ordinary colleague. This makes Wang
The professor always felt that something was wrong, but he couldn't explain it. It seemed that things should be like this.
"Haha, please invite me again when I have the opportunity to come to Hanglin in the future. Mr. Wang has invited me these past few days. He happened to be in Beijing today and promised to come over with Xiao Li later." Professor Wang said with a smile.
Mr. Wang is the agent of Liman Company in China. When we first discussed the cooperation, he came to the Institute of Geology and Mineral Resources and visited their laboratory. Yu Ziqing had met him once and had an impression. Of course, Mr. Wang was very fond of Yu Ziqing.
The clerk must not have been impressed.
Seeing what Professor Wang said, Yu Ziqing stopped insisting.
When it was almost time to get off work, Xiaoli and Mr. Wang came to the laboratory together.
Mr. Wang obviously came to the laboratory often. After entering, he shook hands with Professor Wang warmly and said hello, then patted Xiao Bi's shoulder affectionately. Finally, he turned his eyes to Yu Ziqing, stretched out his hand and said with a smile: "You should be Yu Gong
Well, you are indeed young and promising, and I will need your help in developing the market in Zhehai Province in the future."
Yu Ziqing shook hands with Mr. Wang. He could see that Mr. Wang didn't mean what he said, and he could also see that Mr. Wang didn't take him seriously. The main purpose of going out in person this time was probably to have more emotional exchanges with Professor Wang.
, and his arrival is just an excuse.
Sure enough, before getting off work, Mr. Wang had been taking the initiative to find topics to chat with Professor Wang. He only occasionally chatted with Yu Ziqing casually to take care of the situation. However, Professor Wang was afraid of neglecting Yu Ziqing, so he would bring him in to chat from time to time.
Mr. Wang's condescending and hypocritical style made Yu Ziqing quite unhappy. If it were not for Professor Wang's face and the future cooperation between the unit and Liman Company, Yu Ziqing would have left in a hurry.
