Scholar’s Advanced Technological System

I watched the whole day's paper until Liu Rui's kid started to fight, and Lu Zhou took Hatch and went to bed to sleep.

The next day, I got a bed.

Going to the canteen to buy two buns, Lu Zhou came to the laboratory on time.

When he arrived, two brothers, Liu and his brother, were already beside the instrument and were busy.

What is to be done today is to map the ftir of each sample by Fourier infrared spectrometer, and record the absorption peaks of various functional groups and chemical bonds in the early-stage hydration reaction of carbon nanotube modified samples.

"... Our research is mainly aimed at enhancing the solubility of carbon nanotubes in Portland cement and improving the bonding between carbon nanotubes and matrix materials." While conducting experiments, Qian Shixi 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 next to him, asked: "Where is the specific problem?"

"The problem is here, the data we measured by the Fourier infrared analyzer, look here," Qian Shixiu pointed to the ftir image just printed, and continued, "What did you see?"

Resist the impulse to waste points, Lu Zhou stared at the still hot a4 paper for a long time, suddenly recalled what he learned when he saw the paper yesterday, and his heart moved slightly, and I saw it from the drawing. There is something wrong with it.

“Is the characteristic peak of the No. 2 cement sample abnormal?” Lu Zhou said in an uncertain tone.

“Right, but not accurate,” Qian’s brother nodded and nodded. He pointed out several places on the ftir image and continued. “No. 2 sample is a cement sample mixed with cnts, which is detected according to mechanical properties. As a result, our 2 samples performed quite well in the compressive capacity test, but the performance in the tensile test was not satisfactory. According to the characteristic peak data at the 6-10 h age on the ftir image, we initially judged The cnts material hinders the polymerization process of the silicon tetrahedron in the csh gel, leading to the formation of pores inside the cement material in the later stage of the hydration reaction."

"Where is the problem?" Lu Zhou wondered. "I mean... Since we already know the reason why the tensile strength of the No. 2 sample is not satisfactory, can it be solved?"

“It’s not as simple as you said,” Qian’s brother said with a blank expression. “We have tried many methods, including using melamine as a nitrogen precursor, regardless of production cost, and ball milling the carbon nanotubes under vacuum conditions. The surface of the carbon nanotubes was functionally modified...but from the tensile test data for samples No. 27 and No. 28, the results were equally bad."

Lu Zhou generally understood, but he did not have a better way.

Nodded, he went on to ask, "What do I need to do?"

Qian brother: "In order to find out the solution, we have done a lot of experiments. Although the budget is still sufficient, even if we do a few more groups, it is okay, but a few days ago we learned that the material science laboratory is bigger. Breakthroughs may have been made on this project, and time has not allowed us to continue to drag down."

After a moment of pause, Qian brothers sighed and continued.

“We need an expert who is proficient in mathematics. It is best to be proficient in functional analysis and help us analyze these experimental data to see if we can find some valuable clues. It is best to help us find cnts material for Portland cement early. What is the impact of the ageing hydration reaction? I have self-learned functional analysis, but I still have no clue about these data. If it involves such a difficult calculation, I still have to entrust you to these experts. ""

Just as the mathematics department of the undergraduate stage does not open the course of material physics, the applied physics major does not open the functional analysis of this course. After all, the number of people who have obtained double degrees in the undergraduate level is a minority. Most of them are qualified to self-study those courses they have not taken according to the needs of their own research.

After thinking about it for a while, Lu Zhou said seriously: "I can't guarantee that it will succeed, but I can try it... When do you want the result?"

"The sooner the better, although I can't wait for it... but it's best to be within three days." Qian brother thought about it and continued. "After three days, with or without results, I hope that you can at least give I report progress."

Lu Zhou nodded: "I try to."

After receiving the task from Qian’s brother, Lu Zhou went to the library.

Although Liu’s brother gave him a desk to work out, the lab was too cold and the learning atmosphere was not strong enough.

In contrast, Lu Zhou still prefers a place like a library.

Sitting among a group of people who are eager to write a book, even if they want to walk the fish, they will not be able to stand the sense of urgency and guilt, and put their minds on learning.

And the most important thing is...

More or less here reminds him of the feeling of a high concentration of attention.

Passing through the printing room next to the library, Lu Zhou turned around and printed the papers and experimental data to be printed on a4 paper.

Spreading all the things you need to use on the table is his habit of delving into complex math problems.

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

Sitting in the library and looking for a seat, Lu Zhou picked up the pen and gently clicked on the draft paper, ready to start writing.

however……

Ten minutes passed.

He still sat there in that position and did not move.

Emmmm......

Where do you start?

Lu Zhou’s face was a bit unsightly, and his heart was difficult.

If there is a fixed formula to use, or even if there is a clear goal placed there, he can also conceive where to start. But now the situation is that the research dogs in the hospital have not found any problems, let him who is engaged in mathematics to help them find bugs.

Recalling the words of the brothers.

It’s really a matter of skill...

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

At this time, he suddenly realized that the work did not seem so simple.

......

People are iron rice is steel.

Even if you are a tyrant, you have to eat.

Sitting at the library at twelve o'clock, Lu Zhou looked at the unsuccessful draft paper, and the heart whispered a mmp. When he threw the pen on the table, he got up and went to the cafeteria.

When he was cooking in the cafeteria, Lu Zhou happened to meet Lao Tang, and he walked up the plate and said hello, sitting opposite him.

After looking at the eye, Lao Tang smiled and asked: "How do you feel?"

"It's hard! It's much harder than pure math problems." Lu Zhou said with emotion.

“It’s hard to be right,” Professor Tang said with a smile. “Mathematics is a research tool, and you are studying applied mathematics. There are still many opportunities to encounter similar projects in the future.”

"Professor, can you not hit me first, give me some ideas?" Lu Zhou sighed.

"I can't give you the idea. This can only be searched for by yourself, but I suggest you can give it a little bit," Professor Tang smiled and continued. "Did you not participate in the Mathematical Modeling Competition? a feeling of."

The brow wrinkled slightly, Lu Zhou pondered for a while, but soon shook his head: "It's totally different. The reason why the aerospace problem can be turned into a mathematical problem is because it is ultimately a matter of mass motion and a formula that can be relied upon. And ready-made data..."

"In fact, it is the same." Lao Tang shook his head. "Whether it is the movement of spacecraft, the movement of particles, or the change of functional groups... For mathematics, it is essentially the same in nature. Anything that exists, All the data hidden in the depths can be mined, and there are rules that can be calculated. Mathematical models can be built. It can't be found, just because your efforts are not in place. Think more, observe more, I believe you can definitely Discover the clues."

After listening to Professor Tang’s words, Lu Zhou’s face showed a thoughtful expression.

Looking at Lu Zhou, who was thinking deeply, Lao Tang nodded in his heart.

The scorpion can teach too.
