I Have a Research Support System

Xu Qiu began to type.

There was no buzzing of instruments or voices around, and he quickly entered the state.

I wrote several paragraphs in a row, and finished the entire GIWAXS, together with the characterization parts of TEM and AFM.

No one bothered, and it was very efficient.

Originally, he was already mentally prepared to be interrupted by Han Jiaying occasionally.

I thought she would ask him a few questions from time to time, but I didn't expect her to be quite quiet.

Xu Qiu glanced in her direction.

I found that the school girl was writing and scratching in the experiment notebook while looking at the computer, as if she was taking serious notes.

Yes, my apprentice really looks like me.

Xu Qiu also did similar things when he first started reading literature.

He will record the core content in the literature or the questions he doesn't understand in his notebook, and then ask senior sister Chen Wanqing for advice.

Later, as the amount of reading increases, it is no longer necessary to do this, and the important points will remain in my mind after reading.

As for other details, if necessary, you can search for the WORD summarized by Mr. Wei, or the PPT summarized by the senior sister.

Han Jiaying seemed to notice Xu Qiu's gaze.

She raised her head and looked at him suspiciously.

"It's okay, keep busy." Xu Qiu said hurriedly.

"Something..." Han Jiaying said:

"Brother, I have a question to ask."

Well, I shouldn't have looked at that one more time, this time it's time for trouble.

However, you still have to be responsible for what you say.

Xu Qiu pulled a swivel chair, sat beside her, and said:

"Tell me, what's the problem?"

"Here, light absorption spectrum, what does normalization mean, why do some graphs need to be normalized, and some graphs don't." Han Jiaying said.

"Well, first of all, you need to understand what the so-called normalization means," Xu Qiu said:

"We consider a curve above the horizontal axis, and then set the maximum value of the vertical coordinate of this curve, that is, the extreme value, to 1, and then divide the vertical coordinates of all other points by this extreme value to obtain a new curve , the process of obtaining a new curve is normalization.

When the values ​​of the vertical coordinates of the two curves are very different, and it is not easy to compare them on the same axis, we can normalize them, so that they can be compared more conveniently.

As for when to use normalization, it mainly depends on what the author wants to express.

If they want to compare the light absorption range of two materials, then the absolute value of the ordinate is not important and can be normalized.

However, if the author wants to examine the light absorption coefficients of the two materials, then the absolute value of the ordinate is compared at this time, and normalization cannot be performed. "

"So that's the case, I understand." Han Jiaying nodded and asked again:

"It's still the light absorption spectrum. What does the a.u. on the ordinate next to it mean? I remember it represents the atomic unit, which is generally used in quantum mechanics, but it obviously doesn't apply here."

"Undecided, quantum mechanics?" Xu Qiu made a joke first, and then explained seriously:

"This is because a.u. has multiple meanings, and 'u.' means unit.

But 'a.' can be an abbreviation not only for 'atomic' but also for 'arbitrary'.

Therefore, a.u. here stands for any unit.

In fact, it is also related to the normalization just mentioned. When the ordinate is in any unit of a.u., it means that its absolute value is not important. At this time, normalization is definitely possible. "

"So that's it, brother knows a lot."

Han Jiaying put down the notebook in her hand, stretched, looked at Xu Qiu, and said:

"I feel that the literature looks exhausting. Is there any shortcut? Senior brother can't hide it from teaching me."

"Don't tell me, there really are, do you want to listen?" Xu Qiu asked mysteriously.

"If you want, tell me quickly, brother." Han Jiaying said coquettishly.

"Read three documents every day, and then..." Xu Qiu hesitated.

"Then?"

"Then, tell me."

"Is this a shortcut?" Han Jiaying tilted her head and thought for a while, then said:

"It seems to be a shortcut, thank you brother."

"..."

Originally, he just wanted to make a joke with her, why did he feel that he had cheated himself.

But until now, I can only bite the bullet and take it.

In fact, this idea is somewhat similar to his system, that is, there is a hand-in-hand guidance of highly skilled people.

As long as you work hard, the speed of improving your skills will naturally not be slow.

Compared to a stand-alone computer, it is naturally a shortcut.

...

After dinner, continue to code words.

The self-closing code word was really efficient, and Xu Qiu coded another big chapter in a row.

According to this progress, the article in his hand can be completed within this week.

Han Jiaying came back from the door and said:

"Brother, I just went to the laboratory to check. The solution in the extraction tube of the Soxhlet extraction has turned colorless and transparent for six reactions. Do you want to shut it down?"

"Shut it down. It turns colorless and transparent, which means that the polymerization product has been purified. The next step is chloroform extraction. It's too late to do it today." Xu Qiu said:

"By the way, are you going to the Boiling Point club to participate in rehearsal tomorrow?"

"That's right, rehearse once this Wednesday, rehearse next Tuesday, and then officially perform on stage next Wednesday." Han Jiaying said.

"Then prepare well for the performance, and I will help you with the next experiment," Xu Qiu said.

"Yeah." Han Jiaying nodded.

Immediately, the two went to the laboratory and put on protective equipment.

Stop the reaction, take out the product wrapped in filter paper from the extraction tube, dry it roughly, then wrap it in aluminum foil, number it, and put it in a vacuum oven.

Vacuum oven, you can turn on the heating function, but it is not necessary.

Simply keep the vacuum atmosphere and ensure that the materials are stored away from light.

Finally, dispose of the waste liquid, soak the dirty glass instruments into the alkali tank, confirm that the water and electricity are turned off, turn off the lights and lock the door.

...

On Wednesday morning, Xu Qiu went to class normally.

In class, there was nothing unusual, and the teacher did not call names.

While listening to the class, he flipped through the previous courseware of this course.

"Nanomaterials" is mainly a popular science course. Although it is a degree course, the content is not professional.

At least, for Xu Qiu, there is no pressure to learn by himself.

A bit like a liberal arts class, most of the content is more about memorization than understanding.

However, because he skipped a lot of classes before, he couldn't finish his self-study in a while.

It seems that we still need to spend more time at the end of the semester to make a surprise attack, maybe we can get an A.

According to his observation, the professional courses of the material department are relatively simple. He usually listens to the lectures normally, and takes three or five days before the exam to get an A grade.

What is difficult is the compulsory courses of science, such as "Mathematical Analysis" and "Physical Chemistry".
