Scholar’s Advanced Technological System

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

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

Mathematical modeling...

The nib was lightly pointed on the draft paper, and Lu’s line of sight was found on a sheet of a4 paper.

The data provided by Qian Shixiong to him is very comprehensive, but in other words, it is messy.

There is only one way to the truth, and useless data does not broaden the horizons of the researchers, but instead becomes a hindrance to the truth.

“The problem is that the cnts material has an effect on the hydration reaction in the early age when it is incorporated into Portland cement, so it is only the data of the No. 2 sample.”

“The ftir images of samples No. 2, No. 4 and No. 27 indicate that this effect is not related to the surface functional modification of the cnts material. The experimental data from samples No. 24 to No. 28 can be deleted...”

A few sheets of a4 paper were smashed into a ball and thrown into the trash can in the corner. Lu Zhou wrote two lines of formula on the paper.

[di={k2cme/(2dμ)}·(2pw/pw)】

[vi=(2pw/pw)^n]

Looking at the two lines of formula, Lu Zhou's mouth angled a smug arc.

This is a good beginning……

Let him delve into the impact of carbon nanotubes on the matrix material, perhaps not in his professional scope, but if he only allows him to mine data from the ftir image, using mathematical tools to analyze the rules, you can still do it.

Time passed by, and the sky outside the window gradually faded.

Throughout the afternoon, Lu Zhou completed the preliminary collation of the data and built a simple mathematical model based on the idea of ​​mathematical modeling.

This mathematical model contains the parameters of the cnts material on the Portland cement hydration reaction rate, reaction temperature, sample mechanical properties, ftir characteristic peak region, and the relationship between specific parameters.

When setting these formulas, Lu Zhou directly quoted the paper he once published in the Journal of Theoretical and Applied Mathematics. There are several generalization theories about the Fourier inversion transform, and it is found that unexpectedly a large amount of computation can be saved here.

With the establishment of the first mathematical model, the original complex problem is like a cloud, and the difficulty is reduced by one level.

Lu Zhou leaned back in the chair and stretched out.

Staring at the open matlab interface on the screen, his pupils re-ignited a strong war.

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

Then use the power of the computer to dig the data that is buried in the "invisible"!

......

It seems that I had retrieved the state when I wrote Zhou’s conjecture proof paper. For three days, Lu Zhou maintained a two-point life in the library and dormitory. In addition to eating out of the cafeteria on time, this regular life has hardly changed.

However, even so, as of the evening of the third day, Lu Zhou only completed the establishment of the second set of models, just using an iterative algorithm to find that the cnts material is hydrated at various ages when it is incorporated into Portland cement. The law of the influence of the reaction temperature.

There are also three unknown parameters that need to be calculated.

From the overall assessment, Lu Zhou only completed this work to 60% to 70%.

But already at this point, the rest of the work is easy, just constantly calculating, and recalculating!

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

When I was on the road, I thought about it and gave the money brother a call.

As soon as the phone was connected, there was an eager voice coming from the other end.

"How is the progress?"

Resist the urge to yawn, Lu Zhou licked his nose and replied: "Give me two more days, two days will definitely be done."

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

In the Mathematical Modeling Contest, there is also a programming big bull that can help write programs and make charts with sas, and a blame that will bring 666 to the meal.

Thinking of this, Lu Zhou could not help but feel the emotion.

Sure enough, there is still a missing assistant.

"...you can't do it." Qian's brother's tone is full of doubts.

He is not doubting the strength of Lu Zhou in the field of mathematics. After all, the prover of Zhou’s conjecture is the name of the cow.

However, the strength of the field of mathematics cannot be directly equivalent to the scientific research ability of other fields. Many people have engaged in pure-number research for a lifetime, and their mathematics skills are in full swing, but their achievements in the whole life are only stopped in the field of pure numbers.

Although this is nothing, after all, the industry has a specialization, not everyone belongs to the application of talent.

But at this juncture, he does not want to see Lu Zhou suddenly drop the chain.

Lu Zhou mouth corner is awkward: "Oh, I can't wait for two days and you will know."

"..."

This voice is very spiritual.

Although the mind is suspicious, the money brother did not say anything.

I have waited for three days, is it still two days?

The only thing that made him and Professor Li Rongen feel uneasy was that the recent overwhelming appearance was a bit uncomfortable, just like a big move. The two sides have a lot of overlaps on this "carbon nanotube modified cement-based composite material" research project, and even the base material in the project is Portland cement.

This makes people panic.

Especially their projects are caught in a bottleneck...

Hanging up the phone, I have already walked into the canteen of the canteen. I just put the phone back in my pocket and suddenly another phone call came over.

Take a look at the phone, it was Wu fat child.

When the button was pressed, Lu Zhou brushed the meal card and brushed it on the card reader of the barbecue bibimbap window, while yawning.

"Hey?"

Wu Fatzi: "Is it busy recently? I haven't seen you in these days."

Lu Zhou thought about it: "The research project of the Institute is related to carbon nanotube materials."

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

Lu Zhou was surprised and asked: "Do you know?"

Wu Fatzi smiled and smiled: "Isn't it a lab relocation last year? The broadband and routers there are I brought people to install."

Lu Zhou: "..."

Wu Fatzi coughed a little and continued: "Tomorrow afternoon, I plan to bring people together to open a meeting to discuss the promotion plan after the new version is launched. Do you have any time to come over?"

"No time, I am too busy these days," with his arm on the phone, Lu Zhou put the meal card back into his pocket, took the plate from the canteen of the canteen, and said, "Would you like... Can you organize the meeting yourself?"

Wu Fatzi couldn’t help but say, "Da, don’t you just pick up the shopkeeper from the beginning?"

Lu Zhou also felt that this was not very good, but there was really no time for it. He coughed and said: "This is not a stage for you, let alone I have estimated that I can't give any good advice. Come on! I I am optimistic about you, the future general manager!"

Wu Fatzi: "...?"

There is nothing wrong with it, and he also believes that he is the general manager.

However, the last few words of Lu Zhou.

How does he feel that some are familiar?

......

time flies.

Two days passed in a blink of an eye.

Looking at the stack of draft paper piled up at the corner of the table, sitting in the empty classroom of Lu Zhou, my heart was full of emotion.

It is already a little early in the morning.

After the library closed, he went to the empty classroom with his computer bag and worked hard for hours. He finally completed the final steps.

How much has been paid for this project, I am afraid that only his own heart is clear.

Lu Zhou felt a sentence in his heart, and entered several sets of data into the computer. With the powerful computing power of the computer, he completed the final blow to the enemy spring water.

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

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 looking at the numbers on the computer screen, a strange expression appeared on his face.

a=0?

This is impossible!

No, wait...

Think about it from another angle.

If his calculations are not in error, the resulting a parameter is indeed equal to zero.

This means that...

When cnts materials are incorporated into Portland cement, they have no effect on the hydration reaction in the early age!

Hell...

(ps: conclusions and proofs of ideas from the Journal of Composite Materials 2017 edition 03, the time of the novel is only in 2014, relative to this point in time should be considered "black technology." In addition to the topic, after all, science fiction, in order to The rhythm of the plot, some places will certainly carry out art processing, I can only be close to reasonable in the field I know, and with the advancement of the plot, there will definitely be more and more black technology, and I will still look at the pats. Um, I will say this one time, and if I have more words, I will leave it to the May 1st. I will say that it is important to ask for a recommendation~~~~)
