Chapter 477: Six hundred and sixty-six, the expert is by my side...

At noon a few days later, when Xu Qiu was having lunch at home, her mother Bai Xiaofen suddenly said, "Son, the child from a friend of Aunt Shuyan’s friend’s house wants to come over to see you this afternoon. Her high school belongs to the second middle school of the provincial capital. I just finished the college entrance examination this year and entered Zhejiang University..."
The relationship between Aunt Shuyan and her mother Bai Xiaofen is probably similar to that of a girlfriend. The former rented a small shop in the pedestrian mall in her hometown, opened a clothing store, and started a small business.
To exchange good books, follow the vx public account [Book Friends Base Camp]. Pay attention now to receive cash red envelopes!
When Xu Qiu was a child, he often saw each other coming from home. However, since he went to the provincial capital to study in high school and then was admitted to the Magic City University, he hadn't seen Aunt Shu Yan for many years.
Xu Qiu did not reject their visit. He took a sip of the stewed noodles in a bowl and asked casually, "Oh, is it a man or a woman?"
"It's a girl, and their hometown is also ours. They are fellow villagers." When Bai Xiaofen said the word "girl", her eyes seemed to shine.
"Okay, then see you." Xu Qiu nodded casually.
"Let me talk to Aunt Shu Yan..." While talking, Bai Xiaofen suddenly showed an inexplicable smile, and Xu Qiu looked straight at her hair: "When will you bring a girlfriend home? I watched this girl from Zhejiang University. Yes, how about you communicate with her well..."
Xu Qiu shook his head quickly, and found an excuse: "...I am now a freshman, and Zhejiang University is only a freshman. It is four grades off, right?"
He and Han Jiaying have not been told to his family. It’s not that Xu Qiu intends to open a fish pond to raise fish. The main reason is that his mother Bai Xiaofen nags:
As a mother, when she is single, she will urge to find a partner; when she finds a partner, she will urge to marry; when married, she will urge to have a child...
It's better to talk later.
"It's only four grades short," Bai Xiaofen refuted Xu Qiu's point of view, with a persevering look: "If you count your two years of studying earlier, maybe your actual age is two or three years behind, it's still appropriate..."
Arguing with his mother is impossible to win, Xu Qiu chooses to divert the subject: "When are they coming in the afternoon?"
"I don't know this yet, let me ask you Aunt Shu Yan." Bai Xiaofen was really distracted and started to send messages slowly using handwriting input.
Xu Qiu quickly finished the stewed noodles in the bowl, dropped his chopsticks, and sneaked into his bedroom.
After closing the door, Bai Xiaofen's voice was heard from afar: "They came over at three o'clock in the afternoon--"
Xu Qiu responded in the air: "Okay—"
At about 3:30 in the afternoon, the doorbell rang.
Bai Xiaofen got up and opened the door to entertain. There were three people outside the door.
Among them, one is Aunt Shu Yan. Although I haven't seen each other for a few years, Xu Qiu can still recognize each other. The other two are strangers. They seem to be the mother and daughter. It is a high probability that they will be the visitor we made today.
Xu Qiu looked at the two strangers roughly.
The younger girl, neatly tidy, short hair, good looks, kind of like a girl next door, I don’t know if it’s Xu Qiu’s illusion, he feels that the other person is staring at him as soon as he enters the door. .
Older mothers dress more formal and look well maintained. They may be dedicated housewives or engaged in non-physical work.
In the relatively backward fifth-tier cities like their hometown, many families still live relatively reluctantly, and many of them have not even escaped poverty.
For example, Xu Qiu's high school enrolled in the Hongzhi class, and nearly half of the students came from poor families.
For another example, washing machines are not fully popularized in their hometowns. If the conditions at home are not good and cannot afford a washing machine, housewives have to use washing powder, soap, and washboard to wash clothes manually. If things go on like this, hands will definitely change. It will not be maintained well.
From the appearance of the mother and daughter, the family conditions are likely to exceed 90% of the families in their hometown.
Xu Qiu took the initiative to step forward and greeted: "Hello, Aunt Shu Yan."
Shu Yan smiled and said with a slight dialect accent: "Xu Qiu, since you went to the provincial capital to study, it has been a long time since you have seen you. When I was young, I used to hold you and play."
After speaking, Shu Yan turned and pointed at the strange mother and daughter and introduced: "This is Liu Qingqing, this is Liu Qingqing's mother, Hu Yao, today I mainly brought Liu Qingqing over, and you ask Xu Qiu for advice."
Xu Qiu waved his hand modestly: "I can't talk about advice, but Liu Qingqing, if you have any doubts about college, I can tell you."
Bai Xiaofen waved to Xu Qiu and Liu Qingqing: "Then you go and chat inside, we will chat in the living room outside."
Hu Yao also nodded: "Qingqing, you can go with Brother Xu Qiu."
Liu Qingqing walked to Xu Qiu's side according to the words, and said, "Okay~"
Xu Qiu was a little bit dumbfounded in his heart. This is doing everything possible to create opportunities for himself, but he doesn't need it.
However, he did not refuse, and took Liu Qingqing to the study.
It is really not convenient for the juniors to communicate if there are adults nearby.
Who knows, as soon as the two entered the study, Liu Qingqing stared at Xu Qiu and said: "Xu Qiu...senior, I seem to have seen you...have you been on Weibo hot search before? That one?"
"I did go to a hot search on Weibo..." Xu Qiu nodded, recalling the situation in his mind.
It was a bachelor's degree. His graduation thesis was selected as one of the top ten outstanding graduation thesis in the country. He was also interviewed by Modu TV. In the end, he was also on Weibo hot search and hot list at the same time.
However, the popularity did not last long at that time, and it was squeezed by traffic stars.
It's been more than half a year now, and I didn't expect it to be recognized.
To be honest, there is basically no one who pays attention to the scientific research circle in his hometown, which is why Xu Qiu rarely mentions his circle in his hometown.
If you forcibly talk to relatives and friends outside the circle about the specific situation in the scientific research circle, although it is a bit inappropriate to describe it as "playing the piano against the cow", it does have the meaning of playing the piano against the cow.
No way, the scientific research circle is a relatively remote place for most people, and it is also a very unfamiliar concept.
Like most other professions, whether it is doctors, lawyers, civil servants or whatever, ordinary people can see, come into contact with, and can imagine the specific situations of these professions.
For most people, scientific research is like a black box. Not only is there relatively little news coverage, but the threshold for understanding the specifics is also very high.
Apart from going to graduate school in person, it is basically difficult to understand the more real scientific research circle through other means.
Because now whether it is a popular novel or a popular TV series related to the scientific research circle, the traces of artistic processing are too much, and it is good that the reduction degree can be 50%.
It can be said that today's scientific research circle is one of the industries most detached from the world.
After receiving a positive response from Xu Qiu, Liu Qingqing's eyes lighted up, a bit like a fan met a star, but she was more restrained and did not rush over directly, but her tone was still very excited:
"It must be you. I remember that I just finished the college entrance examination at that time, and I was waiting for the college entrance examination results. When I checked Weibo, I saw the report about you. I was very impressed. You were wearing a white coat. I still saved the photo of. I didn’t expect to see a real person today!"
When she was young, star chasing was a common phenomenon. Liu Qingqing also chased stars, but she was not the same as other people of her age. She didn't like the motherly kimchi national stars. She worshiped famous scientists and paid close attention to scientific research. News.
Unfortunately, there are too few scientific research-related news reported in the mainstream media. In many cases, there is no valuable news for several days.
Therefore, when Xu Qiu's deeds appeared on Weibo, Liu Qingqing immediately followed Xu Qiu.
At that time, she also searched Xu Qiu's Weibo and wanted to follow it, but unfortunately, she didn't find it because Xu Qiu didn't play Weibo.
Later, when Liu Qingqing finished the college entrance examination, she originally wanted to go to the Magic University to study in the footsteps of idols, but found that her score was not enough...
Then, thinking about taking the second place and going to the Modu Jiaotong University, which is also located in the Modu, the score was still not enough...
But if she goes to other colleges and universities in Magic City, such as Tongji University, she is a little unwilling.
So, Liu Qingqing finally ran to Zhejiang University.
After all, Zhejiang University is also good at engineering. She thinks that since the outcome of the college entrance examination is doomed and cannot be changed, she will wait for graduate students and then go to the Magic University for postgraduate studies.
Liu Qingqing stuttered with excitement: "I, I, wait... you can sign me."
"Haha, of course." Xu Qiu was touted by Liu Qingqing for a while, and he asked casually: "Liu Qingqing, this year's college entrance examination, Zhejiang University, how many points did he score?"
Liu Qingqing responded: "The naked score is 641 points, plus 20 points for the provincial one chemistry competition bonus."
"Yes," Xu Qiu exclaimed: "You have a higher score on the college entrance examination than mine at that time, so why don't you come to Demon University?"
"I originally wanted to go to Magic University, but the score was not enough," Liu Qingqing stuck out his tongue: "Maybe this year's college entrance examination questions are simple, and the scores are relatively high. My province's science ranking is 132th, and the scores of Magic City Jiaotong University are relatively high. I couldn't make it up, so I went to Zhejiang University in the end."
Xu Qiu nodded. At the beginning, he was ranked more than 70 in science in the province for the college entrance examination. Generally, the top 50 students in the province went to Qingbei University, Hong Kong University, and Hong Kong University of Science and Technology. After that, 50-150 students went to Magic City Comprehensive University and Magic City Transportation. University, Zhejiang University.
Among them, Modu Comprehensive University may be because the number of recruits is relatively small, only about 10 people, so the score line is the third highest, second only to Qingbei University.
"What major did you choose?" Xu Qiu asked again.
"Chemistry." Liu Qingqing said crisply.
"Chemistry..." Xu Qiu repeated, and then gave a thumbs up: "If you have courage, do you prefer scientific research?"
"Yeah." Liu Qingqing nodded, and then asked back: "How does Senior Xu Qiu think of the chemistry major, if you want to do research later."
"You look quite like me, and you also like chemistry. My choice when I was undergraduate was also the material chemistry that had something to do with chemistry." Xu Qiu did not directly answer Liu Qingqing's question, but changed the conversation and asked: " If you want to do research...How are your family conditions?"
Although Liu Qingqing had some doubts as to why Xu Qiu asked this, he still replied in earnest: "...It's okay, I'm in a catering business at home."
Xu Qiu let out an "um" and continued to ask: "Then how is your math?"
"It's okay... My math competition is the second prize in the provincial competition. It is said that if you are three points away, you will be able to enter the provincial first. It is a pity." Liu Qingqing paused and said: "The first semester of freshman high mathematics was a little difficult , But I brushed "Jimidovich" and scored 92 points in the final exam of this semester."
"Um...what about English?" Xu Qiu asked.
"The college entrance examination score is 145. I just passed the fourth level this year, but the score has not yet come out. I guess it is at least 600 points..." Liu Qingqing responded.
"666, the expert is by my side..." Xu Qiu compared a 6 with his hand, shook it, and asked, "What about the grade point?"
Liu Qingqing received Xu Qiu’s compliment and was very helpful. His face was a little red. After a few seconds, he responded: "...Grade point, grade point is 4.51. This semester I failed to take a ZZ course. If the total grade point is reached, otherwise Xu Qiu quickly reacted. The grade point of Zhejiang University should be a 5-point system, which should be 3.61 when converted into a 4-point grade point system of Magic University Comprehensive University, which is still relatively fierce. Yes, a proper female academic bully is just a little bit worse than when he first entered school.
After understanding Liu Qingqing's basic situation, Xu Qiu thought about it for a while and said:
"First of all, not everyone is suitable for scientific research. If you are not very obsessed with scientific research, I actually suggest that you consider switching to computer or economic management... However, at Zhejiang University, it is good at engineering. It may not be a good idea to transfer to economics. Choose, but it is a good choice to switch to a computer and become a program lady. At least in terms of the difficulty and income of subsequent employment, the salary and ease of employment of computers must be far better than chemical in a short period of time."
After listening to Xu Qiu's words patiently, Liu Qingqing said with a smile: "But people prefer scientific research~"
"Well, then when I didn't say anything just now." Xu Qiu spread his hands, he could see that Liu Qingqing's faith was firmer, maybe it was influenced by the family.
Xu Qiu blindly guessed that Liu Qingqing's father or mother was obsessed with scientific research, but they missed it for some reason and didn't have the opportunity to enter the industry, so they wanted their daughter to experience the life they once dreamed of instead.
Next, Xu Qiu said intermittently: "If you choose scientific research, you can take a semester of professional courses in the winter vacation in advance, and then take more credits in the next semester..."
"In this way, you will have enough time to join the research group in your sophomore year to get a rough idea of ​​what scientific research is..."
"Because of scientific research, you still need to feel it yourself. Even if I am telling you about it, you may not be able to understand it..."
"Well, then...you can tell me the direction you want to choose, and I can give you some suggestions..."
"In the future, if you are in your junior year, confirm that you want to take the path of scientific research, I suggest you choose the path of going abroad..."
"Whether it is considered from the perspective of gilding or broadening horizons, if you are determined to do scientific research, going abroad at the graduate level is the most cost-effective choice..."
"Then you can find the school you probably want to go to in advance, and prepare for the corresponding language test. If you want to save money, you can start to prepare for the school yourself. If you want to save trouble, you can find an overseas study agency to handle it..."
"In addition, we must be psychologically prepared. Girls choose scientific research, and it may be several times more difficult for girls to achieve positive results than boys..."
"Hmm...Hmm..." Liu Qingqing nodded thoughtfully, and finally said, "Shall we add a WeChat account? We may have to consult Senior Xu Qiu later."
"Yes." Xu Qiu scanned the WeChat account that added Liu Qingqing. The other party's profile picture was a travel photo, next to the iron tower in Bali.
If the photo is not a PS, it means that Liu Qingqing's family is indeed very good, because the family is in a fifth-tier city, and families who can go abroad are very rare.
Like Liu Qingqing, if you have a family backed up, you can really stick to the career you love. Even if you fail, you can't stick to it, and you can retreat.
Liu Qingqing: "Then what should I do to prepare for scientific research now?"
Xu Qiu:
It’s not a rush. First, finish the basic subjects of the freshman year. The grade points in the freshman year are still more important. When you join the research group in your sophomore year, you will naturally know what scientific research is. You will understand. If you still don’t understand at that time, you can come to me."
Liu Qingqing: "What about ordinary people, do students' unions and clubs need to participate?"
Xu Qiu: "Look at your own social needs, I almost never participated in the student union or club anyway."
Liu Qingqing pursed her lips, and suddenly asked, "Senior, do you have a girlfriend."
Xu Qiu was caught off guard by this question: "...Yes."
Liu Qingqing ignited the soul of gossip: "I met you in college?"
"Yeah..." Xu Qiu responded and closed the door of the study, worrying that his mother Bai Xiaofen would hear it.
Liu Qingqing seemed a little confused: "What was love in college like? I haven't talked about it yet."
Xu Qiu: "Try it yourself and you won't know. According to your terms, there should be no shortage of suitors."
Liu Qingqing: "There are a few, but none of them feel that way. Let's not talk about this. Let's talk about Senior Xu Qiu and your girlfriend."
As a result, the topic in the second half was completely crooked, and the two of them were talking about Xu Qiu and Han Jiaying almost all the time...
After talking for more than 20 minutes, Xu Qiu found that Liu Qingqing had a rather strict tutoring in middle school and had never been in a relationship, so she had a longing for love in college, but she felt that her peers were too naive and could not find a suitable candidate. .
This is also the price of maturity.
At this moment, Liu Qingqing took out a small pink book from her pocket, turned to a brand new page, and looked at Xu Qiu expectantly: "Senior Xu Qiu, sign me, if ...If you can write a message, that would be even better."
"Yes." Xu Qiu took the small book and said inwardly: "I also sent a message...I am not a liberal arts student..."
Xu Qiu pondered for a moment, and then wrote down the motto of the Modu University: "Knowledgeable and dedicated, inquisitive and thoughtful."
Then, Xu Qiu signed his name again and successfully dealt with it.
Liu Qingqing, Hu Yao and Aunt Shu Yan didn't stay long, and left after five o'clock.
After that, the days continued to fall into the ordinary.
The days of being incapable of showing the saints passed quickly, and it was time to return to school in a blink of an eye.
Xu Qiu called Ctrip's customer service in advance to ask about the itinerary.
Then, he learned that the itinerary had been printed out by Ctrip, and he only needed to fill in the mailing address of the itinerary online, and then he could send it back by post.
In addition, this winter vacation and Xuqiu were quite fulfilling. Before leaving home, he got the latest results of the simulation laboratory.
The highest efficiency of binary single junction devices based on Y series acceptor materials has reached the 18% threshold successfully!
Specifically, the acceptor material used is Y20, and the donor material is L6-Cl.
L6-Cl is based on the previous L6 material developed by Zang Chaojun and Lu Changjun's research group, and introduced a chlorine atom into the BDT unit.
The processing method adopted is spraying, 90 degrees Celsius thermal spin coating volume fraction addition, vacuum storage for 16 hours, no annealing, no solvent annealing.
This breakthrough did not seem to have encountered any bottlenecks, and everything was a matter of course.
But in fact, it is not entirely a matter of course, but there is time for this big killer
On the one hand, the simulation laboratory II and III run at full power during the winter vacation; on the other hand, the simulation laboratory I will often play, such as synthesizing these new donor materials. In order to get the materials faster, Xu Qiudu It is synthesized by speeding up by yourself.
Therefore, if the actual exploration time is converted into real time, it can reach more than one year.
Now, Xu Qiu's last article on "Science" on laminated devices has now been submitted for review. Here, the second CNS level work, the L6-Cl:Y20 system, has begun to line up again.
For this job, Xu Qiu intends to vote in "Natural~EbookFREE.me~". However, after returning to school, he will have to perform a performance, trying to make L6-Cl and Y20 a reasonable synthesis step by step.
On February 18th, Xu Qiu took a plane and returned to the magic city.
Speaking of it, Xu Qiu didn’t take a lot of planes before. There was a big reason. He was enrolled in his freshman year. When he flew from his hometown to the magic city for the first time, he developed earaches during the voyage, and he felt very painful. obvious.
When Xu Qiu returned home from the magic city before the Chinese New Year, he thought that his ears would still hurt when flying on a plane, but found that there was no serious pain.
Now, returning to school from hometown again, Xu Qiu found that his ears started to hurt again during the voyage.
However, the level of pain was not as serious as the first time I took an airplane in my memory.
Xu Qiu speculated that flying from the south to the north is prone to ear pain, and flying from the north to the south is not easy to have ear pain? Probably related to air pressure?
Unfortunately, there are too few samples and only rough inferences can be obtained.
