The more important thing that Jiang Yucheng encountered was the ongoing Dachuang project defense meeting - a year ago, Jiang Yucheng accepted Mr. Deng's invitation to set up a project team together and applied to participate in Daiso. With the strong support of their mentor Lao Xu www.biquge.info they successfully got this national-level project with a budget of 5W yuan. Of course, this so-called "project", like most other science and engineering projects, is a guise for selling dog meat on the head of a sheep and using existing results to cheat funds.

However, the ready-made results have other benefits: when Jiang Yucheng had time before, he also ran to the laboratory twice in three days, and made something with the brothers and sisters in the laboratory; However, after all, he is still a full member of the project team, and the necessary obligations still have to be fulfilled: like today's defense meeting, the new project team that participated in Daso for the first time will participate, and Jiang Yucheng's group will participate in the project although it has been approved last year, but it will also participate - their project has been going on for a year now, and they need to do a mid-term defense, just like the midterm exam of a certain professional course.

Although it is said that it is necessary to defend it, in fact, there are not many things that need to be prepared - all the "dry goods" such as experimental data are handled by Lao Xu, and Jiang Yucheng and they only need to be responsible for using these "dry goods" to make PPT. Under normal circumstances, the work of explaining on stage should be handed over to Mr. Deng, who is the leader of the project team, to do it - he has sharp teeth and a thick voice, which is suitable for this.

However, Mr. Deng couldn't come today because of something, so he had to let Jiang Yucheng deal with it - it just so happened that Jiang Yucheng also felt that although he was just a name in the group, if he didn't do anything, it really seemed a little too inappropriate.

But to Jiang Yucheng's surprise: when he walked into the classroom of the defense meeting, he actually saw a familiar figure - despite such a hot summer, the guy was still wearing a black windbreaker, with a long black straight head, lying lifelessly on the table:

"Yu Baochen?!"

He had the impression that this guy didn't seem to have any reason to be in this classroom.

“…… Yo, Sao Nian!"

Yu Baochen rolled his head around, faced Jiang Yucheng with his hair-stained face, and responded listlessly.

Unlike Jiang Yucheng's surprise, Yu Baochen did not express much surprise at Jiang Yucheng's appearance -- after all, it is really normal for students of the National People's Congress to participate in the defense meeting of the National People's Congress at the venue of the National People's Congress...... Jiang Yucheng did Dachuang, Yu Baochen also knew, so naturally there was nothing strange about it.

"You... Why are you here?" Jiang Yucheng asked in surprise, "You're also... Reported a big creation?"

"Well, it's not a registration," Yu Baochen waved his hand, "It's just that I'm being pulled to fill the number..."

"It's a lot of numbers..."Jiang Yucheng, who was a relative, easily understood what she meant, "Who is the main speaker?"

"Him. Yu Baochen pointed to the boy on the stage, "Our squad leader, Zhuge Ming." ”

Jiang Yucheng looked up and took a closer look, and saw a boy talking to the teacher - his face was healthy and dark, with high cheekbones and pointed chin, his eyes were always shining, and the hair on his forehead was a little sparse, as if there were some signs of premature aging. Regardless of the aura of the scholar for the time being, at least the whole person flashes with a shrewd and capable bearing.

It turns out that although theoretically speaking, Yu Baochen can also be regarded as a participant in Daiso, but in fact she is really just a soy sauce maker - this is also in line with Jiang Yucheng's consistent impression of her... And the real protagonist is now talking endlessly on stage, the class president of Yu Baochen's class, a sophomore at Polytechnic University, Zhuge Ming. According to Yu Baochen, their project team is the product of a collaboration between a professor from the Polytechnic University and a professor from the Department of Chemistry -- but apart from Zhuge Ming and Yu Baochen, no other college students have participated in the project.

"In order to improve the pyroelectric detection value of thin films, it is feasible to use porous membrane or multilayer membrane structure design to reduce the dielectric constant of the system. For pores, the introduction of low dielectric constant holes in the film can reduce the overall dielectric constant of the film. The multilayer film process prepares two or more films, the structure of the film is equivalent to two capacitors in series, and the dielectric constant of the composite film after series connection is smaller than that of the first two films without composite, and the detection excellence value of the composite film prepared by this method can also be improved. However, these two methods also have their own shortcomings: the leakage current density of porous films is relatively large, and the preparation method is very difficult, while the role of multilayer films in reducing the dielectric constant and improving the detection excellence is not obvious.

In response to this situation, this project uses BI0.5 (NA0.82K0.18) 0.5TiO3 (NKBT) Combining the respective advantages of porous membrane and multilayer membrane structure, the sandwich composite film with double-layer dense film and porous film was designed and prepared by sol-gel method, and the low-temperature crystallization and texture control of sandwich film were expected to be realized simultaneously through the introduction of seed layer at the interface, which provided a new idea for the design of pyroelectric films with complex structures......"

Zhuge Ming gushed endlessly on the podium, but Jiang Yucheng was not interested in what he said - this project is obviously in the inorganic direction, and Jiang Yucheng is now doing organic synthesis, and he wants to develop in this direction in the future. As for Yu Baochen, this master is even more fierce: she finally didn't make up for sleep on her stomach, but she sat in the audience and was "blind, very busy", nodding up and down from time to time, completely looking drowsy - according to her own introduction, she was too excited last night, tossing and turning until midnight to sleep peacefully, and this morning she got up early to participate in the defense, and now her spirit is extremely tired... Looking at the appearance of this goods, Jiang Yucheng sighed: Fortunately, the speaker of today's defense is not her, otherwise this project would have to be smashed.

"Hey, I said you're a guy..."Jiang Yucheng complained, "You can't pay attention, don't be so obvious?

"Well, well, I'm a dozen soy sauces, it's the same with me or not..."The sleepy-eyed Yu Baochen said nonchalantly, "-Besides, this project is supposed to be nine out of ten, and washing the road with peace of mind is..."

Yu Baochen said in detail that Zhuge Ming and Professor Zhuge participated in this big creation for the same purpose as other groups, of course, to get some extra financial subsidies. However, compared to the other teams of the White Wolf with Empty Gloves (including Jiang Yucheng's group), Zhuge Ming had plenty of dry goods on hand - he and his mentor had been working on this project for a long time and had already made some achievements. Since the other "bragging groups" can pass, how can their group with dry goods be rejected? In her opinion, it is certainly safe to pass the defense.

"By the way, why did they pull you into the project team?" Jiang Yucheng asked, "Don't tell me that you also participated in the research - I'm 100% sure that you are not such a person..."

"I'm really not the material to do this, and I really can't help much in research-" Yu Baochen generously admitted this, but claimed jokingly: "But Zhuge Ming said that I have some "profound thoughts" and "extensive knowledge", and the project can be used." And the things that have participated in the project are written in the file, which will be very face-saving, and the postgraduate entrance examination work will be beneficial. In that case, I would not have been able to refuse him. But I had already made it clear to him that I couldn't do the experimental research, and I would do my best to do everything else - and he just agreed. ”

The current project defense is in a large classroom on the first floor of the public teaching, and the professors in charge of the evaluation are lined up in the front row, and the members of the various experimental project teams are sitting in other positions. Among the two people in Yu Baochen's group, the team leader Zhuge Ming was responsible for putting PPT and explaining the defense, while Yu Baochen was waiting in the audience. Listening to Yu Baochen himself, the project mentor told her before that if Zhuge Ming was stuck, let her try to help him answer. However, Yu Baochen has never paid much attention to professional things - before the defense meeting began, she had just held the project report in her hand, and she flipped through it with sleepy eyes. Taking the report from Yu Baochen's hand, Jiang Yucheng looked through it and felt that even if he drove the ducks on the shelves now, he might be more helpful to Zhuge Ming than Yu Baochen!

"That's all for my report, and I welcome questions from teachers. Zhuge Ming bowed and finished the report, but he looked like he was in the chest - after all, he had already produced some solid results before, and this project was objectively cutting-edge. There was some applause in the classroom. Jiang Yucheng saw that Yu Baochen seemed to be trying to make himself more sober, so he applauded vigorously and slapped his hands red.

The PPT on the projector went exactly to the last page - Jiang Yucheng noticed that in the final reference, there were four papers. The first author of these papers is all "M.Zhuge", and the last paper is written in bold with a small line: JournalOfTheAmericanChemicalSociety (Note 1)

"Damn?!" Jiang Yucheng was scared on the spot, "What's the matter with this buddy?!Undergraduate students send JACS?!And tm is the first author?!"
