Scholar’s Advanced Technological System

I read the paper all day, and until Liu Rui's kid started to snore, Lu Zhou crawled into bed and fell asleep.

The next day, I got up early.

Lu Shun went to the cafeteria to buy two buns, and Lu Zhou came to the laboratory on time.

When he arrived, Brother Liu and Brother Qian were already around the instrument and were busy.

What I want to do today is to plot the FTIR spectrum of each sample with a Fourier infrared spectrometer, and record the absorption peaks of each functional group and chemical bond of the hydration reaction of the carbon nanotube modified sample in the early age.

"... Our research is mainly aimed at enhancing the dissolving ability of carbon nanotubes in Portland cement, and at the same time improving the bonding force between carbon nanotubes and the matrix material." While experimenting, Brother Qian introduced to Lu Zhou, "But the progress of the research is not optimistic. Professor Li should have told you that we have encountered a bottleneck."

Lu Zhou, who was watching beside him, asked, "Where is the specific problem?"

"The problem lies here. We measured the data through the Fourier infrared analyzer. Look here," Brother Qian pointed to the FTIR image just printed, and continued, "What did you see?"

Refraining from the urge to waste points, Lu Zhou stared at the hot A4 paper for a long time, and suddenly remembered what he learned when reading the dissertation yesterday, and his heart moved slightly, and she could see from the drawing There is nothing wrong.

"Anomalies in the characteristic peaks of No. 2 cement sample?" Lu Zhou said in an uncertain tone.

"Correct but not accurate," Brother Qian nodded approvingly, pointed out a few places on the FTIR image, and continued, "Sample No. 2 is a cement sample with CNTs incorporated. The results show that our 2 samples performed very well in the compression resistance test, but the performance in the tensile test was unsatisfactory. According to the characteristic peak data at the age of 6-10h on the FTIR image, our preliminary judgment is The CNTs material hinders the polymerization process of the silicon tetrahedron in the CSH gel, which leads to the formation of pores in the cement material in the later stage of the hydration reaction. "

"Where is the problem?" Lu Zhou wondered, "I mean ... now that we know the reason for the poor tensile strength of Sample No. 2, as long as it is solved?"

"It's not as simple as you said," Brother Qian said blankly. "We have tried many methods, including melamine as a nitrogen precursor, regardless of production costs, and ball milling carbon nanotubes under vacuum. The carbon nanotube surface was functionally modified ... but from the tensile test data of samples 27 and 28, the results are just as bad. "

Lu Zhou roughly understood, but he had no better way.

He nodded and he asked, "What do I need?"

Brother Qian: "In order to find a solution, we have done a lot of experiments. Although the budget is still sufficient, even if we do a few more, there is no problem, but a few days ago we learned that the material science laboratory over there Breakthrough progress may have been made on this project, and time has not allowed us to continue to delay. "

I paused for a moment, Brother Qian sighed and continued.

"We need an expert who is proficient in mathematics. It is best to be proficient in functional analysis to help us analyze these experimental data and see if we can find some valuable clues. It is best to help us find the CNTs material early on Portland cement. What is the impact of age hydration reaction ... I have studied functional analysis on my own, but I still have no clue about these data. Sure enough, it involves such difficult calculations. I still have to entrust your experts in these institutes . "

Just like the undergraduate mathematics department does not offer a course in material physics, so does the subject of functional analysis in functional physics. After all, there are few people who have obtained a double degree at the undergraduate level. Most of them choose selective self-study courses on their own according to the needs of their research direction after they have been admitted to graduate students.

Lu Zhou thought for a moment, then said seriously: "I can't guarantee success, but I can try ... When do you want results?"

"The sooner the better, although I can't wait here ... but it's best within three days." Brother Qian thought for a while and continued, "After three days, whether or not there is a result, I hope you can at least give I report progress. "

Lu Zhou nodded and said, "I try."

After receiving the assignment from Brother Qian, Lu Zhou went to the library.

Although Brother Liu gave him a desk, it was too deserted in the laboratory and the learning atmosphere was not strong enough.

In contrast, Lu Zhou prefers places like libraries.

Sitting among a group of hard-working people, even if you want to walk away and touch the fish, you will not be able to hold back the urgency and guilt in your heart and put your mind on learning.

And the most important thing is ...

Here is more or less a reminder of how he felt when he was highly focused.

过 Passing the printing room next to the library, Lu Zhou turned in and printed all the papers and experimental data to be printed on A4 paper.

Spread all the things you need on the table. This is his habit of studying complex mathematical problems.

Anyway, it can be reimbursed as research funding, and he does not need to spend his own money.

I found an empty seat in the library and sat down. Lu Zhou picked up the pen and tapped it slightly on the draft paper, ready to start writing.

However ...

Ten minutes passed.

He was still sitting there in that position, without moving.

Emmmm ...

哪里 Where do I start?

Lu Zhou's face was a little unsightly, and he had a hard time in his heart.

If there is a fixed formula that can be used, or even if there is a clear goal in there, he is good at figuring out where to start. But the current situation is that the scientific research dogs of the Institute did not even find the problem, and let him, a mathematician, help them find bugs.

I recalled Brother Qian's words.

I really do it by my skill ...

Looking at the pile of data, Lu Zhou only felt scalp.

At this moment, he suddenly realized that the work was not as simple as it seemed.

Uh ...

People are iron rice is steel.

Even if you are an overlord, you have to eat.

坐 At twelve o'clock in the library, Lu Zhou looked at the untouched draft paper and said secretly in his heart ~ www.readwn.com ~ Throwing his pen on the table, he got up and went to the cafeteria.

When he was cooking in the cafeteria, Lu Zhou just met Lao Tang, so he walked up to the plate and greeted him, sitting opposite him.

I glanced at Lu Zhou, and Lao Tang smiled and asked, "How do you feel?"

"It's hard! It's much harder than purely mathematical problems," Lu Zhou said with emotion.

"I feel right," Professor Tang said with a smile. "Mathematics is a scientific research tool, and you are learning applied mathematics. In the future, there are still more opportunities for similar projects."

"Professor, can you stop hitting me first and give me some ideas?" Lu Zhou sighed.

"I can't give you ideas. You can only find this one yourself, but I suggest I can give you a little bit," Professor Tang smiled and continued. "Did you not participate in the Mathematical Modeling Contest? Remember that time a feeling of."

Frowning slightly, Lu Zhou meditated for a while, but then quickly shook his head: "It's completely different. The reason why the aerospace problem can be turned into a mathematical problem in the final analysis is that it is a problem of particle motion and a formula that can be relied on. And ready-made data ... "

"Actually the same." Old Tang shook his head. "Whether it is the motion of the spacecraft, the motion of the particles, or the change of the functional group ... For mathematics, it is essentially the same. Anything that exists, There are deep data that can be mined, there are laws that can be calculated, and you can build mathematical models. You can't find them, just because your efforts are not in place. Think more and observe more, I believe you can definitely Discover the clues. "

After listening to Professor Tang's words, a thoughtful expression appeared on Lu Zhou's face.

He smiled at the thinking Luzhou, and Tang nodded in his heart.

Bitch can be taught also.
