I Have a Research Support System

Six thirty in the morning.

Sample No. 72, the test is completed.

Except for a few abnormal points appearing in the middle, and the position of the sample needs to be readjusted, no other accidents occurred.

"Huh—the sample is finally finished," Chen Wanqing said with a long breath:

"Next, test a blank silicon wafer. When processing the data later, it is used to subtract the background. The exposure time used by all samples must be measured once on the silicon wafer."

...

Blank silicon wafer, tested.

"Finally, lanthanum hexaboride needs to be tested to calibrate the coordinates of the center of the circle and the distance between the sample stage and the signal detector.

This is to measure X-ray transmission. The suction table needs to be removed, and then the lanthanum hexaboride sample holder prepared by the light source in advance is inserted into the sample table.

Because of its very high signal strength, only 2 seconds of exposure is required. "Chen Wanqing said.

...

Lanthanum hexaboride, tested.

After all the tests were completed, Chen Wanqing checked the saved data files one by one, confirmed that all samples had been tested, and then copied the data to the USB flash drive.

The data is in tif image format with very high precision, so the files are very large, adding up to more than 10 GB in total.

It took more than ten minutes to copy the files, and after confirming the files in the USB flash drive again, she sent a text message to Luo Yang, telling him that the test was finished and she would leave early.

Xu Qiu turned off the X-ray at the main console, and put the experimental garbage produced by the two people in the garbage bag.

Come to the guard room again, return the personal radiation meter and access control card, and record the time of departure.

Take a taxi back to school.

After arriving at the dormitory, Xu Qiu simply washed up and fell asleep.

…………

July 27th, Sunday, is the first day of Baoyan Summer Camp.

However, the main schedule of the first day is that the colleges and departments take the postgraduate students from outside the school to visit the campus and the magic city.

So Xu Qiu didn't join in the fun, but came to the laboratory as usual.

After he entered, he sat next to Chen Wanqing, and just as he took out his computer, he heard Teacher Wei's footsteps.

So, he casually opened a PDF of a document, pretending to be reading the document.

Wei Xingsi walked in, walked around the laboratory first, and saw Wu Feifei doing experiments in the glove box.

He checked the oxygen value and water value of the glove box, and they were all within the normal range, so he nodded at Wu Feifei and returned to his desk.

"Duan Yun, after your article was submitted, the experiment will start. How is the progress recently?" Wei Xingsi said.

"When I was doing tests with Mr. Zhou Dagang of Tongji University, I asked them how to build thermoelectric equipment, and now I am trying to build one by myself.

Because there is no ready-made equipment on the market that meets our testing needs, we need to buy various accessories and assemble them ourselves. I am looking for various accessory companies to negotiate prices. " Duan Yun said.

"Indeed, I still have to set up a set of equipment by myself. It's not good to bother others all the time, and I have to post their names after posting articles." Wei Xingsi said:

"Okay, what do you need, let their company make a quotation and ask me to reimburse you."

Duan Yun scratched his head and said:

"Now the equipment I'm sure I want to buy is two Keithley 2400 source meters, which will cost about 80,000 yuan in total."

"It's so expensive, have you negotiated the price with them?" Wei Xingsi frowned, and his expression became serious.

"Of course we negotiated the price. At first they quoted a price of 100,000 yuan." Duan Yun said.

"Couldn't it be replaced by a cheaper source meter?" Wei Xingsi asked.

"Cheap ones are not accurate enough." Duan Yun said.

"Okay, if you really need it, then buy it. In terms of finances, let Wu Feifei help you operate it." Wei Xingsi shouted towards the laboratory: "Wu Feifei, help Duan Yun buy equipment when you have time."

"Okay, I see." Wu Feifei said.

"Chen Wanqing, did your light source test go well?" Wei Xingsi turned his head and asked.

"It went well. We prepared 72 samples and finished all the tests. It may take two or three days for data processing." Chen Wanqing said.

"Okay, you can teach Xu Qiu how to deal with the data and ask him to help. Now your article is short of this data. You need to fix it before the holiday and submit the article," Wei Xingsi said:

"Duan Yun and Wu Feifei's two review articles have both been rejected, and now it's up to you."

After finishing speaking, Wei Xingsi looked at Xu Qiu again, found that he was reading literature, and said:

"Xu Qiu, I've read the final report you wrote, and it's not bad. How is your English article doing now?"

"The article is being written, and the English article is still not as smooth as the Chinese one. I guess I can't finish it before the holiday." Xu Qiu said.

"It's okay, take your time," Wei Xingsi said, "It's always like this when you write the first article. If you have time during the summer vacation, you can also write it, and show it to me after the vacation is over."

"Okay." Xu Qiu nodded.

…………

After Teacher Wei left, Xu Qiu said to the senior sister:

"You just said that it takes two or three days to process the data of the light source. Are you serious?"

"Yes, each data has to be processed separately, which is very troublesome," Chen Wanqing said helplessly:

"It includes the steps of subtracting the background, integrating, and converting the gray-scale image to a color image. It takes about ten to twenty minutes for each data to come down."

Xu Qiu suddenly thought that he copied the skills of teacher Luo Yang from the light source before, so he opened the system interface to check.

The GIWAXS method of light source testing characterizes the "molecular stacking structure" of materials, and its proficiency is 80% for the second order/30% for the fifth order.

Seeing this value, he sighed in his heart, Teacher Luo Yang deserves to be specialized in this field, and his proficiency has broken through the fifth level of 0%.

He was a little curious, what is the proficiency of senior sister?

"System, can I check Chen Wanqing's proficiency in this skill?"

[Chen Wanqing's proficiency in "Molecular Stacking Structure Representation" is 40% of the fourth order. Do you want to copy and overwrite the current data? 】

"No coverage, no coverage."

Xu Qiu hurriedly blocked the system, if it was overridden, he would cry to death.

He checked the system image and found the data processing part.

The simulated villain inside uses a software called fit2D to process the light source data, and finally uses MATLAB software to batch export the grayscale images into color images, and it only takes three minutes to process one data on average.

When he downloaded the origin software before, he saw MATLAB software in the school's "genuine software" library.

Xu Qiu used the computer to download MATLAB. The size of the software was more than 20 GB. Fortunately, the network speed of the campus network was very fast, and the download speed could reach 20-40MB per second.

…………

After Chen Wanqing copied the light source data in the USB flash drive to the computer, he began to process the data, and at the same time taught Xu Qiu the method.

Although Xu Qiu had learned more advanced methods, he still decided to listen patiently.

He wanted to see how the senior sister's method went wrong, and it actually took nearly five times more time if there was a problem.
