Chapter 144: Schoolgirl

　　 This afternoon, Teacher Wei went to the hospital to see the cervical spine, not in the office.
　　 Therefore, at around 5:30, the other friends in the laboratory started to pack their things and prepare to flash people.
　　 Only Xu Qiu and Han Jiaying are still doing experiments.
　　Considering that it is Friday, if you don’t make a reservation to eat out in the evening, the waiting time will not be short for a slightly more popular restaurant. One or two hours is normal.
　　 So, in the middle of the experiment, the school girl temporarily left the glove box, called the Xiaobeiguo restaurant, and booked a spot in advance.
　　 At the same time, Xu Qiu helped her test a device.
　　 While saving the experimental data, he discovered that Han Jiaying’s experimental data were named only with the sample number and the number of tests.
　　 When she came back, Xu Qiu said:
　　"Han Jiaying, there is a small problem here.
　　 When naming the tested J-V curve, in addition to the sample number and the number of tests, the preparation conditions and materials used should also be indicated in the file name.
　　 In addition, data that is particularly efficient should also be marked to facilitate subsequent retrieval.
　　 For example, if you use P2T material, you can add it in the middle of the file name, so you can know what system it is at a glance, and you don’t need to compare the sample number.
　　 For example, 4.55% efficiency, you can add a prefix like ‘4.55_’ before the file name. "
　　 "Okay, I remember, brother knows so much." Han Jiaying said.
　　 "These are all the losses I have suffered before. At that time, I had to find the data I wanted from hundreds of data. You should be able to imagine the difficulty." Xu Qiu said:
　　 "I have suffered a loss, so you don't have to eat it again."
　　 "Hmm." Han Jiaying nodded earnestly.
　　 After all the tests were completed, it was already half past six in the evening.
　　 The two took off their lab coats and returned to the desk. Han Jiaying looked at the time and said:
　　 "It just so happened. I made a reservation at 7:30 in the evening. I don't have to wait too long now."
　　 "Then let's set off. You can leave the school bag in the office and come back to pick it up after eating." Xu Qiu said:
　　 "By the way, where is this store? I haven't seen it before."
　　 "On the Bund, the magic capital Xiaobeiguo is quite famous, right? The branches have opened in our Jiangsu province." Han Jiaying said.
　　 "It turned out to be on the Bund. I thought it was in a nearby business district. The main reason is that I don't pay much attention to the local dishes of Magic City." Xu Qiu said:
　　 "By the way, the Bund is quite far away..."
　　 "This is easy to say, let's take a taxi and go there." After speaking, Han Jiaying smiled:
　　 "I can finally eat the braised pork with grandma over there."
　　 When Xu Qiu saw her eyes, there seemed to be little stars shining in them.
　　 This school girl is a snack, I haven't found it before.
　　……
　　 The two walked to the main entrance of the school.
　　 It didn't take long for the online taxi to arrive, and Xu Qiu helped Han Jiaying to open the back door.
　　 The school girl said "Thank you" first, then got in and sat down in the car.
　　 There is another position in the back row. Xu Qiu thought for a moment, followed in and sat next to the school girl.
　　 The driver's master is a middle-aged uncle. Before the bus started, he said routinely:
　　 "Passengers please wear seat belts."
　　 At night, there was still a little traffic jam on the way to the Bund.
　　 Cars stop and go.
　　 It was dark outside, and the driver did not drive the inner lights. The two of them sat in the back seats, and the atmosphere was a bit subtle.
　　 Han Jiaying spoke first, breaking the silence:
　　 "Brother, for my three systems, is it necessary to use chloroform as a solvent and make another batch of devices?"
　　 "Chloroform solvent, you can try it later," Xu Qiu said:
　　 "However, next week we will go to Zhangjiang to do synthesis first. You can change the side chains of P3T and P5T."
　　 "Okay, how do you generally judge which method is better for several spin coating methods?"
　　 "For the spin coating method, the spraying method is mainly used now. The ordinary method of adding the solution first and then spin coating has basically been eliminated by us." Xu Qiu said:
　　" Ordinary spin coating method, on the one hand, is more wasteful of solution, but the main reason is that the performance is usually worse than spraying method.
　　 As for the thermal coating method, it has a greater impact on our P4T and its derivatives, because they have high crystalline properties and can be adjusted by setting multiple temperature gradients.
　　 But like Chen Wanqing's three systems, the crystallinity of the material is poor, and there is not much difference between hot and cold coating. "
　　 The driver's master suddenly began to discuss academic issues when he heard a man and a woman in the back row.
　　 He was taken aback first, and then thought of where the two of them boarded the car.
　　 They are students of Magic University, that’s not surprising.
　　 The two discussed topics related to the experiment all the way, and time passed quickly.
　　 Waiting for Xu Qiu to recover again, the car has slowly stopped.
　　 The driver's master said very enthusiastically: "Two, we are here, right next to the Bund."
　　 Xu Qiu murmured to himself, when he first got in the car, the master was still a routine, why has it suddenly changed like this now.
　　 He also enthusiastically replied: "Okay, thank you, Master."
After 　　 got off the car, Han Jiaying led the way, and Xu Qiu followed behind.
　　 After a few steps, she came to the door of a hotel. The school girl said happily:
　　 "It's here, Xiao Beiguo is on the seventh floor. Let's take the elevator up."
　　……
　　 Enter the Xiaobeiguo shop and take a seat under the leadership of the waiter.
　　 Xu Qiu looked around, the decoration here is quite exquisite, the occupancy rate is also high, and the Bund can be directly seen from the floor-to-ceiling glass next to it.
　　 However, it’s dark outside now~EbookFREE.me~ I can’t see it very clearly.
　　 If it's daytime, this should be a spot where the magic capital "ladies" like to fight singles.
　　 "Brother, then I'll order food."
"You do it."
　　 Han Jiaying greeted the waiter and said:
　　 "Grandma's braised pork with braised pork, magic crab noodle tofu, four fresh roasted bran, squirrel mandarin fish, rice dumplings."
　　 Then, she asked Xu Qiu, "Do you want to add more vegetables?"
　　 "Five dishes, enough, we two can't eat too much." Xu Qiu said.
　　 He can see it. The school girl said that she was inviting him to dinner, but she wanted to eat it herself, so she brought him over.
　　 The two sat facing each other, but they stopped talking about the experiment.
　　 The dishes are served quickly.
　　 Han Jiaying took a bite of the red meat and said vaguely:
　　 "Hmm...Brother, you recommend some good professional elective courses for me."
　　 "Good? Which aspect is good?" Xu Qiu said.
　　 "Of course it's'less homework, better points'." Han Jiaying said.
　　 "I remember that you are almost finishing your credits?" Xu Qiu said.
　　 "That's right, now I am missing a special one for my elective course."
　　 "Well, then I recommend two to you." Xu Qiu said:
　　" One of the courses is "Inorganic Functional Materials". There is no final exam, only a report is required. If the score is completed, 30% of the A will be full, and the remaining 70% will basically be B+.
　　 The other "Composite Materials" is also not bad. It was opened by my instructor Yu Qiang. The open-book test and the scores are also good. There are no extra coursework for these two courses, and no name is called. "
　　 "I have taken "Inorganic Functional Materials", then I will choose "Composite Materials" next semester." Han Jiaying said.
