Scholar’s Advanced Technological System

I read the paper all day, and it wasn't until Liu Ruinao started snoring that I climbed into bed with Hatchet on the ark.

The next day, I got up in the morning bed.

On the way to the canteen to buy two bags, the ark arrived at the lab on time.

By the time he arrived, Brother Liu and Brother Qian had been surrounded by the instrument and were busy living.

What we need to do today is to map the FTIR of each sample by Fourier Infrared Spectrometer and record the absorption peaks of the functional groups and chemical bonds of the early hydration reaction of the carbon nanotube modified specimen.

“… our research is aimed primarily at enhancing the solubility of carbon nanotubes in Portland cement while improving the bonding between carbon nanotubes and matrix materials.” While conducting the experiment, Brother Qian introduced to the Ark, "but the progress of the research was not optimistic, as Professor Li should have told you, we encountered bottlenecks. ”

And he looked at the ark next to him and asked, “What's the problem? ”

“Here's the problem, the data we measured with the Fourier Infrared Analyzer, look here," Brother Qian pointed to the FTIR image just printed, continuing, “What do you see? ”

After restraining the urge to waste points, the Ark stared at the still hot A4 paper for half a day and suddenly remembered what it had learned yesterday when reading the paper. It moved slightly in its heart, and it was clear from that drawing that something was wrong.

“Abnormal characteristic peak of cement specimen number two?” The ark spoke in an uncertain tone.

“True, but not quite accurate,” Brother Qian nodded in favor of the location and nodded several places on the FTIR image, continuing, "Sample 2 is a cement sample incorporating CNTs. According to the results of the mechanical performance test, our two samples performed fairly well in the compressive capacity test, but the tensile capacity test performed poorly. Based on the characteristic peak data on the FTIR image at 6-10h age, we tentatively conclude that the CNTs material blocked the polymerization process of the silicone tetrahedron in the C-S-H gel resulting in pores forming inside the cement material during the post-hydration reaction. ”

“So what's the problem?” The Ark is confused, “I mean... since we already know the reason for the poor tensile resistance of Sample 2, just fix it? ”

“It's not as simple as you said," Brother Qian said expressionlessly, "We've tried many methods, including using melamine as a nitrogen precursor, ball-milling carbon nanotubes in vacuum conditions, and functionally modifying the surface of carbon nanotubes… but from the tensile test data on samples 27 and 28, the results are just as bad. ”

The ark generally understood, but he didn't have a better idea.

He nodded and went on to ask, "What do you need me to do? ”

Brother Qian: “In order to find a solution, we have done a lot of group experiments. Although the budget is sufficient, even a few more groups are fine, but the other day we learned that the Materials Laboratory over there may have made breakthrough progress on this project, and time has not allowed us to continue to stall. ”

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

“We need an expert in mathematics, preferably in general correspondence analysis, to help us analyze the experimental data and see if we can find some valuable clues from it. It would be best to help us find out exactly what the impact of CNTs material on early hydration reactions in Portland cement is… I have self-taught Pan Letter analysis, but still have no clue about this data, so it is something that involves this highly difficult calculation, or I have to entrust experts from your houses. ”

Just as the undergraduate mathematics department doesn't teach material physics, so does the applied physics major. After all, there are a small number of people who have obtained dual degrees at the undergraduate level, and the majority of them take courses that they have not completed selectively after taking graduate examinations, depending on their own research direction.

After a moment of reflection, the Ark said seriously: “I can't guarantee it will succeed, but I can try… When do you expect the results? ”

“The sooner the better, although I can't wait on my side… it's best to do so within three days.” Brother Qian thought about it and went on to say, "Three days later, with or without results, I hope you can at least report back to me on your progress. ”

The ark nodded: “I'll try. ”

After receiving his assignment from Brother Qian, Ark went to the library.

Although Brother Liu gave him a desk, the lab was too cold and the learning atmosphere was not strong enough.

By contrast, ark boats prefer places like libraries.

Sitting among a group of people who are struggling with their books, even if they want to touch the fish, they can't help but feel the urgency and guilt in their hearts and put their thoughts on learning.

And most importantly…

It reminds him more or less of what it feels like to be highly focused.

Passing the printing room next to the library, the ark turned around and printed all the papers and experimental data to be seen on A4 paper.

Spread everything he needs on the table, which is his habit of drilling complex mathematical problems.

It can be reimbursed as research money anyway, and he does not need to spend his own money.

I found a space in the library to sit down, and the ark picked up the pen and gently tapped on the draft paper to get ready to start.

…

Ten minutes have passed.

He still sat there in that position, not moving a word.

emmmm…

Where do we start?

The face of the Ark is a little ugly, and the heart is in trouble.

If there was a fixed formula available, or even if there was a clear goal there, he could figure out where to start. But what's happening now is, the science dogs at the hotel, they didn't even find the problem anywhere, so let him, the mathematician, help them find BUG.

Think back to Brother Qian's words.

Really dump the pot with skill...

Looking at the data, the ark only felt numb on the scalp.

At this point, he suddenly realized that the task was not as simple as it seemed.

……

Man is iron, rice is steel.

Even the bullies have to eat.

At twelve o'clock in the library, the ark looked at the untouched draft paper, and there was an MMP in his heart, throwing the pen on the table and walking towards the canteen.

While dining in the cafeteria, the ark happened to run into old Tang and walked up to greet him with a plate and sat opposite him.

Looking at the ark, Tang chuckled and asked: “How do you feel? ”

“Hard! It's a lot harder than pure math.” The ark was emotional.

“That's right,” Professor Tang said with a smile. "Mathematics is a scientific tool. You learn applied mathematics again. There are many opportunities for similar projects in the future. ”

“Professor, will you stop hitting me and give me a second thought?” The ark sighs.

“I can't give you the idea, you can only look for it yourself, but I suggest I give you a little,” Professor Tang laughed and continued, “Didn't you participate in the mathematical modeling competition? Remember what it was like. ”

Eyebrows slightly wrinkled, the ark pondered for a while, but quickly shook its head: “Not at all, space problems can ultimately be translated into mathematical problems, because it is ultimately a matter of quality point motion, and can rely on formulas and readily available data...”

“It's actually the same.” Old Tang shook his head, "whether it's the motion of a spacecraft, the motion of particles, or the changes in functional groups… are essentially the same for mathematics. Anything that exists has deep data that can be mined, has computational patterns that can build mathematical models. I can't find it, just because you didn't get your kung fu right. Think, observe, I'm sure you'll find clues. ”

After listening to Professor Tang, a thoughtful expression appeared on the face of the Ark.

Looking at the thinking ark, Tang nodded in his heart.

Kids can teach too.
