I Have a Research Support System

Chapter 272 So as long as the sample size is large enough, the normal distribution will not trouble

If there is no "Nature·Materials" to increase the upper limit of the efficiency of the ADA system to 10%, the efficiency of the senior sister is 6.1%, you can use "outstanding (outstanding)" or "remarkable (extraordinary)" and the like adjectives to describe.

And you can add a sentence at the end, "As far as we know, this is the highest photoelectric conversion efficiency of the current ADA system", so that it is very perfect, not only has B installed, but also makes others have no FUCK to say.

But now, it's hard to be true to be given a big hat by others.

Xu Qiu struggled for two minutes, and finally typed out a word, "impressive".

After thinking about it for a while, I deleted it again, and typed out the four letters "high (high)" again.

Let's describe it in a simple way...

After editing the abstract, move on to the introduction.

One night passed quickly, and Xu Qiu's progress in revising the article was only about 30%. It is really that the progress of the senior sister's ability to write articles is limited, and many of the mistakes she made will be repeated a second time, or even a third time.

It's understandable, after all, language-related things are not like experimental operations, it's hard to make a quick start, and it's hard to correct the wrong usage if you get used to it.

Just like the word "meal" in many restaurants nowadays, they still use a simplified version, only the part in the upper left corner. Of course, this cannot be said to be a "mistake" in the strict sense, but the reason is similar.

On Thursday, Xu Qiu once again spent the whole morning and half the afternoon, finally helping the senior to finish correcting the article.

"Here," Xu Qiu handed the USB flash drive to Chen Wanqing, and said weakly, "I've read it all over, the review mode I used, all traces of modifications are on it."

"Thank you junior," Chen Wanqing took the USB flash drive and happily suggested, "Let me treat you and junior to drink milk tea."

"Okay!" Han Jiaying responded quickly, "Brother, what do you want to drink?"

"It's more refreshing." Xu Qiu thought for a while and said, "Yang Zhi Ganlu."

"Hmm..." Han Jiaying took Chen Wanqing's mobile phone, browsed the merchants in the food delivery software, searched for two minutes, and said, "Then let's order this 'Five Fen Sweet'. I want a cup of Mango Duoduo. How about you, senior sister?" ?”

"I'm the same as you." Chen Wanqing said casually as she was busy revising the article.

A few minutes later, Chen Wanqing synchronized Xu Qiu's changes to her own draft file, and then brought the final version of the draft file to find Teacher Wei happily.

At the same time, Xu Qiu created a new blank WORD file on the desktop of the computer, then put his head on the table, turned his face to the keyboard of the laptop, let himself go, and reviewed the work situation in the past month:

During this period of time, besides doing experiments, he first wrote an NC, then an EES, and finally helped his senior to edit an AM. The three consecutive articles were all high-quality articles.

For this kind of high-quality work, even if the work itself is solid, the choice of words and sentences should not be too casual when writing articles, and paragraphs and sentences must be carefully crafted.

Because whether you are a reviewer, an editor, or other researchers, you know that your work is based on text reading. If the article is full of grammatical errors, spelling mistakes, or looks like a primary school student’s composition, it will undoubtedly affect their understanding of the article. The first impression and overall feeling of the article may have had the opportunity to be published, but it was rejected because of poor language expression.

These days, the smell of wine is also afraid of deep alleys.

Because of this, Xu Qiu devoted a lot of effort to these three articles, so much so that now I feel that my energy is almost drained, and I feel a little vain...

When he remembered that he would write another article about the B3T-6 system of junior girls, he made one head and two big.

Fortunately, that article is going to be submitted to ACSAMI, a journal in the second district, it will be much easier to write, and it can be properly released.

After rolling his face on the keyboard for a while, Xu Qiu raised his head, looked at the computer screen, and found that he did not type out a complete set of Shakespeare, but a bunch of gibberish characters: What is the research and development plan to assist Fan Azhulin to turn it into a 囧 separation system..."

After a closer look, it seems that it is not all garbled characters.

"It seems that my face is still a bit capable," Xu Qiu complained, Xing out the WORD document, and deleted the file.

Friday afternoon, the eve of the holiday.

Chen Wanqing's article was successfully submitted, and Tian Qing's review proposal has also been submitted to the editor.

Xu Qiu and Han Jiaying were dealing with the experimental data of the B3T system, and were not in a hurry to write an article.

Wu Feifei and Sun Wo are still exploring the experimental conditions of the two-dimensional perovskite system.

Duan Yun's experiment seems to have entered a bottleneck period, and the performance of the thermoelectric device is very poor. It is speculated that the quality of the purchased nickel nanowire solution is not good enough.

Wu Shengnan is basically familiar with everyone in the laboratory.

Xu Qiu always felt that Wu Shengnan talked to him very often, and he was a little unclear about the way this new postdoctoral fellow would do, "The female junior holds gold bricks, these two and a half gold bricks are a bit unbearable." '

At around four o'clock in the afternoon, Wei Xingsi appeared at the door of 216, said something like "Be careful during the holidays" with everyone, and finally said:

"You guys clean up the lab. I'll go back first. Close the doors and windows when I leave. Remember to come over on the afternoon of May 5th for the group meeting."

This time, during the May Day holiday, Wei Xingsi did not "cut the head and tail" like the previous National Day holidays, but only "cut the tail", that is, rest from May 1st to 4th, and start work on the 5th.

On the one hand, it is considered that "it seems to be a five-day holiday, but in fact it is only one day", because there are two days of make-up classes including Saturday, Sunday, and before and after the holiday; on the other hand, it is also because Mr. Wei is on holiday I want to take my wife and children to Qiongdao to play.

According to Wu Feifei, Mr. Wei and his wife met during their Ph.D. studies in the beautiful country. The master’s degree he obtained from Shanghai Jiaotong University in China is not recognized abroad, so he studied for an additional three years for a master’s degree and four years for a Ph.D. . During their Ph.D. studies, the two got married and had twins. The two children are brothers and sisters, both of whom are eight years old this year.

Calculated, Wei Xingsi only started a trumpet when he was close to thirty-five years old, which was considered very late at that time. After all, it was a period when the average man and woman were in their early twenties, and when they reached the legal marriage age, they got married and had children.

Teacher Wei's situation is not uncommon in the current scientific research circle. Now many of them are married during their Ph. D., and of course there are earlier ones. Xu Qiu's circle of friends can see undergraduates posting their marriage certificates Yes, if it is later, there will be many people who get married immediately after graduation, but there are also some leftovers, which are basically old men and women, and they may not even have the idea of ​​​​marriage.

Teacher Wei would occasionally take the child to the office on weekends. Xu Qiu had met him a few times before, and he was quite cute.

Currently, the two little ones are studying in the primary school affiliated to the Modu Comprehensive University.

Those who work in the education system, such as college professors and middle school teachers, have excellent educational benefits for their offspring, and they basically don’t have to consider issues such as school district housing from elementary school to high school.

In addition, although their children have to take the college entrance examination as usual, they have the resources of their parents in other ways such as independent enrollment and subject competitions, which will be much more competitive than the children of ordinary families.

Of course, the wide road does not mean that the children will definitely reach the height of their parents in the future.

The reason is also very simple. Even if family factors make their upper limit of development a lot higher, and their lower limit is also raised, but from a statistical point of view, most of the possibilities still fall into the middle result.

Just as the experimental test data usually presents a normal distribution, so is the fate of all living beings. The future of most people is to go to an ordinary university, find a decent job, marry a passable partner, and live a mediocre life. End of life.

"Elite origin" alone is not enough to break this statistical limitation.

However, there are still smart people in the world. Many wealthy people, such as some bigwigs in Hong Kong City, like to have more children to avoid risks.

Since it is a normal distribution, as long as the number of samples is large enough and there are enough births, there will be a high probability that there will be a few very good offspring, and then select qualified successors from them like the selection of heirs by ancient emperors.

...

The four-day holiday is neither long nor short.

Xu Qiu's schedule is:

On May 1st and 2nd, bedroom, house.

On May 3rd and 4th, go out and make waves.

I have no plans to go home, because in addition to the two long vacations in winter and summer, it takes two or three days to go home during the usual minor holidays. The fixed time cost is too high, so I can only call home to report that I am safe.

Han Jiaying's plan was to go home two days ago, and then return to Shanghai on May 3rd to go out and play with Xu Qiu. They checked the weather, and it was sunny on May 3rd and 4th.

Xuemei’s home is in Sioux City, which is very close to the devil. Before, she used to go back home once a week, but later she went back every two weeks. A while ago, she didn’t go home for almost a month due to continuous overtime work. homesick.

Chen Wanqing's hometown is also far away from the Demon City, so she, like Xu Qiu, chose to be a quiet house girl.

As for the other people in the research group, they were either locals in Shanghai, or from Jiangsu, Zhejiang and Shanghai. Some chose to go home, and some took advantage of the small holiday to go out and wander.

From the proportion of students, we can roughly see the imbalance of educational resources.

In a research group, the sample of postgraduates is relatively small, but Xu Qiu is quite familiar with the situation of undergraduates.

Magic City University enrolls more than 3,000 undergraduates each year, half of which are through non-college entrance examinations, including independent enrollment, comprehensive evaluation, high-level art troupes, high-level sports teams, national special programs, special programs for colleges and universities, Hong Kong, Macao and Taiwan free admissions, etc. .

The other half were admitted through the normal college entrance examination, about 1,500 people. For example, the province where Xu Qiu lives only admits about 10 people.

In the year of his college entrance examination, only 12 students were admitted in the whole province combined by the two enrollment methods.

Taken together, the provincial enrollment ratio is less than four per thousand.
