Chapter 52: Does the data processing take 3 days?

　　 Six thirty in the morning.
　　 Sample No. 72, the test is completed.
　　 Except for a few abnormal points occurred in the middle, and the sample position needs to be re-adjusted, no other accidents occurred.
　　 "Huh—the sample is finally finished," Chen Wanqing exhaled and said:
　　 "Next, test the blank silicon wafer, and then when processing the data, it is used to subtract the background. The exposure time used by all samples must be tested on the silicon wafer."
　　……
　　 Blank silicon wafer, the test is completed.
"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 for measuring X-ray transmission. You need to remove the suction table, and then insert the lanthanum hexaboride sample holder prepared in advance with the light source into the sample table.
　　Because its signal strength is very high, it only needs to be exposed for 2 seconds. "Chen Wanqing said.
　　……
　　 Lanthanum hexaboride, the test is complete.
　　 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 U disk.
　　 The data is in tif image format, and the accuracy is very high, so the files are very large, adding up to a total of more than 10 GB.
　　 It took more than ten minutes to copy the files, and after reconfirming the files in the U disk, she sent Luo Yang a text message to inform the other party that they had finished the test and left early.
　　 Xu Qiu turned off the X-ray at the main console, and put the experimental waste generated by the two in the test into the garbage bag.
　　 came to the guard room again, returned the personal radiometer and access card, and recorded the time of departure.
　　 Take a taxi back to school.
　　 Arrived in the bedroom, Xu Qiu took a brief wash, then fell asleep.
　　…………
　　 July 27, Sunday is the first day of the Baoyan Summer Camp.
　　 However, the main schedule for the first day is to visit the campus and the magic city with the graduate students from outside the school.
　　 So Xu Qiu did not join in the fun, but came to the laboratory as usual.
　　 After he entered the door, he sat next to Chen Wanqing. As soon as he took out the computer, he heard the footsteps of Teacher Wei.
　　 So, he casually opened a PDF of a document and pretended to be reading the document.
　　 Wei Xingsi walked in, first walked in the laboratory and saw Feifei Wu doing experiments in the glove box.
　　 He checked the oxygen level and water level of the glove box, and they were all within the normal range, so he nodded at Wu Feifei, and then returned to his desk.
　　 "Duan Yun, after your article is submitted, the experiment will be done, how is the progress recently." Wei Xing thought.
　　"When I was doing tests at Tongji University, Mr. Zhou Dagang, I asked them how to build a thermoelectric device, and now I am trying to build a set by myself.
　　Because there is no ready-made equipment on the market that meets our testing needs, we have to buy various accessories and assemble them by ourselves. I am looking for various accessory companies to negotiate prices. "Duan Yun said.
　　 "Indeed, you still have to build a set of equipment by yourself. It's not good to trouble others all the time, and you have to put their names after posting an article." Wei Xing thought:
　　 "Okay, what do you need, let their company make the quotation, just ask me for reimbursement."
　　 Duan Yun scratched his head and said:
　　 "Now I am sure that the equipment I want to buy is two Keithley2400 source meters, which will cost about 80,000 yuan in total."
　　 "It's so expensive, have you negotiated with them?" Wei Xingsi frowned, and his expression became serious.
　　 "Of course they have bargained, and at first they quoted one hundred thousand." Duan Yun said.
　　 "Can't you replace it with a cheaper source watch?" Wei Xing thought.
　　 "Cheap accuracy is not enough." Duan Yun said.
　　 "Okay, if you really need it, then buy it. In terms of finance, let Feifei Wu do it for you," Wei Xingsi shouted to the laboratory: "Feifei Wu, wait for Duan Yun to 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.
　　 "It went well. We prepared 72 samples. After all the tests are completed, it may take two or three days for data processing." Chen Wanqing said.
　　 "Okay, you can teach Xu Qiu about the data processing methods and ask him to help. Now your article is missing this data. You need to fix it before the holiday and vote the article," Wei Xing thought:
　　 "Duan Yun and Wu Feifei's two review articles have been voted, and now you are the one behind."
　　 After finishing speaking, Wei Xingsi looked at Xu Qiu again and found that he was reading the literature, and said:
　　 "Xu Qiu, I have read the closing report you wrote, and it is not bad. How is the English article now?"
　　 "The article is being written. Writing in English is not as smooth as writing in Chinese. I guess I won't finish writing before the holiday." Xu Qiu said.
　　 "It's okay, take your time," Wei Xing thought: "It was the same when writing the first article. If you have time during the summer vacation, you can also write about it, and show it to me after the vacation."
　　 "Okay." Xu Qiu nodded.
　　…………
　　 After Teacher Wei left, Xu Qiu said to the senior sister:
　　 "You just said that the data of the light source requires two or three days to process. 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, points, and converting the gray value image into a color image. Each data takes about ten to twenty minutes~EbookFREE.me~ Xu Qiu suddenly thought that he had copied the light source Luo Yang before. The teacher’s skills are opened to view the system interface.
The GIWAXS method of 　　 light source test characterizes the "molecular stacking structure" of the material. His proficiency is 80% for the second order and 30% for the fifth order.
　　 Seeing this value, he sighed in his heart that Teacher Luo Yang deserves to be specialized in this field, and his proficiency has exceeded the fifth level 0%.
　　 He is a little curious, what is the proficiency of Senpai?
　　 "System, can I check Chen Wanqing's proficiency in this skill?"
　　 [Chen Wanqing's "Molecular Stacking Structure Characterization" proficiency is level 4 40%, do you copy and overwrite the current data? 】
　　 "No coverage, no coverage."
　　 Xu Qiu is busy blocking the system, if it is covered, he will not cry to death.
　　 He checked the system image and found the data processing part.
The simulation villain in 　　 uses a software called fit2D to process the light source data, and finally uses the software to export the grayscale pictures as color pictures in batches. It only takes three minutes to process one data on average.
　　 When he downloaded the origin software before, he saw software in the school’s "genuine software" library.
　　 Xu Qiu used the computer to download the software. The size of the software is more than 20 GB. Fortunately, the network speed of the campus network is very fast, and the download speed can reach 20-40MB per second.
　　…………
　　 After Chen Wanqing copied the light source data in the U disk to the computer, he began to process the data, and at the same time taught Xu Qiu the method.
　　 Although Xu Qiu has learned more advanced methods, he decided to listen patiently.
　　 He wanted to see the senior sister’s method, at which step the problem occurred, it actually took nearly five times longer.
