Scholar’s Advanced Technological System

After lunch time, Lu Zhou returned to the library and sat down.

Looking back at what Professor Tang said, Lu Zhou calmly looked at the data and draft paper spread out on the table, with a thoughtful expression on his face.

Mathematical modeling ...

The tip of the nib lightly tapped on the draft paper, and Lu Zhou's gaze was looking on the sheet of A4 paper spread out.

Brother Qian Qian provided him with comprehensive data, but to put it another way is messy.

只有 There is only one way to the truth. Useless data does not broaden the researcher's horizons, but will become an obstacle to the truth.

"The problem is that when CNTs materials are incorporated into Portland cement, they affect the hydration reaction in the early age, so only the data of sample No. 2 are useful."

"Comparison of FTIR images of samples 2, 4 and 27 shows that this effect has nothing to do with the functionalization of the surface of the CNTs material. The experimental data from samples 24 to 28 can be deleted ..."

Crushed a few sheets of A4 paper into a trash can in the corner, and Lu Zhou wrote two lines of formulas on the paper.

【Di = {k2CMe / (2dμ)} · (2Pw / ρw)】

【Vi = （2Pw / ρw） ^ n】

Looking at these two lines of formulas, Lu Zhou's mouth twitched a slight radian.

This is a good beginning……

Let him study the impact of carbon nanotubes on the matrix material, which may not be within his professional scope, but if he is only allowed to mine data from FTIR images and use mathematical tools to analyze the laws, it can still be done.

The time passed minute by minute, and the sky outside gradually faded.

During the whole afternoon, Lu Zhou completed the preliminary arrangement of the data and set up a simple mathematical model according to the idea of ​​mathematical modeling.

This set of mathematical models includes parameters such as the hydration reaction rate, reaction temperature, sample mechanical properties, FTIR characteristic peak areas, etc. of CNTs materials in multiple samples to Portland cement, and the relationship between specific parameters.

设置 When setting up these formulas, Lu Zhou directly quoted the paper he had published in the Communication on Theory and Applied Mathematics. Among them are several generalized theories about Fourier inversion transformation, and it is found that a large amount of calculation can be unexpectedly saved here.

With the establishment of the first mathematical model, originally difficult problems are as difficult as a cloud, and the difficulty has dropped by one level.

Lu Zhou leaned on the chair and stretched his waist.

Staring at the open interface in the screen, his eyes renewed a strong fight.

Next, he will use code to compile this model into a program!

Then use the power of the computer to mine the "invisible" data buried!

Uh ...

I seem to have regained the original state of writing the Zhou's conjecture to prove the paper. For three days, Lu Zhou maintained the life of the library and the bedroom at 21:00. Except for the regular appearance in the cafeteria during meals, this regular life has hardly changed.

However, even so, as of the evening of the third day, Lu Zhou has only completed the establishment of the second set of models. Iterative algorithms have just been used to obtain that CNTs materials have been hydrated at various ages when incorporated into Portland cement Gradual change of reaction temperature.

There are three unknown parameters to be calculated.

评估 If we evaluate it as a whole, Lu Zhou only completed this work to 60% to 70%.

But this step has been reached, the rest of the work is very easy, just keep calculating and recalculating!

At half past five, Lu Zhou dropped his pen on the table and went to the cafeteria.

When I was walking on the road, I thought about it and called Brother Qian.

刚 As soon as the phone was connected, an urgent voice came from that end.

"How's the progress?"

Restraining the urge to yawn, Lu Zhou rubbed the bridge of his nose and replied, "Give me two more days, and two days will surely work."

半 The semi-scientific competition of mathematical modeling is still difficult to compare with this serious scientific research project. And the most important thing is that there is no teammate, from mathematical modeling to programming, and the final thesis writing, all work can only be done by himself.

At the time of the mathematical modeling contest, there was also a programming ox who could help write programs and make charts with SAS, and a monster who would bring meals and shout 666.

Thinking of this, Lu Zhou couldn't help feeling.

Sure enough, there is still a miscellaneous assistant ...

"... Can you do it?" Brother Qian's tone was full of doubt.

He is not skeptical of Lu Zhou's strength in mathematics. After all, the prover who proved Zhou's conjecture is hanged by the name of the bull.

However, the strength in the field of mathematics cannot be directly equivalent to the scientific research ability in other fields. Many people have engaged in pure number research for a lifetime.

Although this is nothing, after all, the surgery industry has a specialization, not everyone is an applied talent.

But at this point, he didn't want to see Lu Zhou suddenly drop the chain.

The corner of Luzhou's mouth flickered: "Oh, I can't wait for two days and you will know."

"..."

Hey, it's very spiritual.

Although he was suspicious, Brother Qian said nothing.

I have waited for three days. Is it two days behind?

The only thing that Xun disturbed him and Professor Li Rongen was that the recent silence at Zanda University was a bit out of place, as if he was doing a big move. The two sides have a lot of overlap in the research project of this "carbon nanotube modified cement-based composite material", and even the base material in the project is Portland cement.

This makes people panic.

Especially their project has fallen into a bottleneck ...

I hung up the phone, and Lu Zhou, who had already entered the cafeteria, had just put the phone back in his pocket, and suddenly another call came over.

I took out my mobile phone and looked at it. It was Wu Fatty who called.

Pressed the connect button, Lu Zhou yawned while pulling out the rice card and swiping it on the card reader of the barbecue bibimbap window.

"Hey?"

Wu Fatty: "What have you been doing recently? I haven't seen you these days."

Lu Zhou thought for a while and said, "The research project of the Institute is related to carbon nanotube materials."

Wu Fatty: "666, Carbon Nanotube Materials Research Institute? Great!"

Lu Zhou asked in surprise: "You know?"

Wu Fatty smiled, "Is n’t I relocating the lab last year? I brought people to install the broadband and router there."

Lu Luzhou: "..."

Wu fat man coughed and continued, "I plan to gather people for a meeting tomorrow afternoon to discuss the promotion plan after the new version is launched. Do you have time to come over?"

"No time, I've been too busy these days," Lu Zhou held the phone back in his pocket, and Lu Zhou took the dinner plate from his aunt in the cafeteria, saying, "Well ... look at it Can you organize that meeting yourself? "

Wu fat man could not cry and laugh and said, "Boss, don't you be a shopkeeper in the beginning?"

Lu Zhou also felt that this was not very good, but he really didn't have time and he coughed and said, "This is not the stage for you, let alone I can't come up with any good opinions. Come on! Bullish on you, future general manager! "

Wu fat man: "...?"

It's no fault, and he thinks he's the general manager.

Alas, the last few words of Lu Zhou.

怎么 How did he feel that he had some familiarity?

Uh ...

time flies.

In a blink of an eye, two days passed.

Looking at the stack of draft papers at the corner of the table ~ www.readwn.com ~ sitting on the land boat in the empty classroom, my heart was filled with emotion.

It's one o'clock in the morning.

After the library closed, he carried a computer bag to an empty classroom and worked hard for hours, finally completing the final steps.

I only know how much he paid for this project.

Lu Lu sighed in his heart, entered several sets of data into the computer, and used the computer's powerful computing power to complete the final blow to the enemy spring.

Then, import the resulting sets of data into formulas ...

Suddenly, Lu Zhou stared at the draft paper and stopped, unconsciously stopping the pen in his hand.

Looking at the numbers on the draft paper and at the numbers on the computer screen, a weird expression appeared on his face.

Α = 0?

This is impossible!

No, wait ...

I think from another angle.

If his calculation is correct, the final α parameter is indeed equal to 0.

This also means ...

The CNTs material did not have any effect on the hydration reaction in the early age when it was incorporated into Portland cement!

Damn it ...

(PS: conclusions and proofs of ideas Sources from the Journal of Composites 2017 Edition 03, the time of the novel is currently only 2014, compared to this time point should be considered "black technology". In addition, a digression, after all, science fiction, for The rhythm of the plot, there will definitely be art processing in some places, I can only be close to reasonable in the areas I know, and as the plot advances, more and more dark technology will definitely appear, and I hope that the big guys will pat .Well, let's talk about this time off topic, let's leave a lot of words to the testimony of May 1 on the shelves, the important thing is to ask for a recommendation ~~~~)
