After lunch time, Lu Zhou returned to the library and sat down.
Lu Zhou recalled what Professor Tang said and calmly looked at the data and draft papers on the table. He had a thoughtful expression on his face.
Mathematical modeling …
The tip of the pen gently tapped on the draft paper as Lu Zhou's eyes searched through the A4 papers.
The data provided by Brother Qian was comprehensive, but it was messy.
There was only one way to the truth. Useless data could not broaden the vision of researchers, but it would become an obstacle to the truth.
"The problem is that when the CNTs material is mixed into the Portland cement, it affects the hydration reaction in the early stage. Therefore, only the data of sample No. 2 is useful.
"Comparing the FTIR images of samples No. 2, No. 4, and No. 27, the effect has nothing to do with the surface functionalization of the CNTs material. The experimental data from samples No. 24 to 28 can be deleted …"
He crumpled the A4 papers into a ball and threw them into the trash can in the corner. Lu Zhou wrote down two lines of formulas on the paper.
When Lu Zhou looked at the two lines of formulas, he smirked.
This is a good start …
Asking him to delve into the impact of carbon nanotubes on the matrix material might not be within his scope of expertise. However, if he was only asked to mine the data from the FTIR images and use mathematical tools to analyze the patterns, he could still do it.
Time slowly passed by and the sky outside the window gradually dimmed.
Throughout the afternoon, Lu Zhou completed the preliminary sorting of the data and established a set of simple mathematical models according to the ideas of mathematical modeling.
This set of mathematical models included parameters such as the hydration reaction speed, reaction temperature, sample mechanical properties, FTIR characteristic peak area, and other parameters in multiple samples, as well as the relationship between specific parameters.
When setting up these formulas, Lu Zhou directly quoted the paper that he had published in Theoretical and Applied Mathematics Communication. Among them were several generalizations of the Fourier inverse transformation theory. He found that he could save a lot of calculations here.
With the establishment of the first mathematical model, the originally complicated problem was solved, and the difficulty was reduced by one level.
Lu Zhou leaned back in his chair and stretched.
As he stared at the Matlab interface on the screen, his pupils were reignited with a strong desire to fight.
The next step was to use code to compile this model into a program!
Then, with the help of the computer, he would dig out the "invisible" data!
…
It was as if he was back to the time when he wrote Zhou's conjecture. For three days, Lu Zhou split his time between the library and his dorm. Other than showing up at the cafeteria on time during mealtimes, this kind of routine almost didn't change at all.
However, even so, by the evening of the third day, Lu Zhou had only completed the establishment of the second set of models. He had just used an iterative algorithm to obtain the progressive law of the effect of the CNTs material on the hydration reaction temperature of each age when it was mixed into Portland cement.
There were still three unknown parameters that needed to be calculated.
From an overall evaluation, Lu Zhou had only completed 60% to 70% of this work.
But now that he had reached this step, the rest of the work was easy. He just had to keep calculating and calculating!
At half past five, Lu Zhou threw his pen on the table and went to the cafeteria.
While he was walking, he thought for a bit and called Brother Qian.
As soon as the call connected, he heard an anxious voice.
"How's the progress?"
Lu Zhou resisted the urge to yawn and rubbed the bridge of his nose. He replied, "Give me two more days, I'll definitely be done in two days."
The mathematical modeling competition was a semi-scientific research competition. The difficulty was still incomparable to this kind of serious scientific research project. The most important thing was that he did not have a teammate. From mathematical modeling to programming, he had to rely on himself to write the final thesis.
During the mathematical modeling competition, he had a programming expert who could help him write the program and make the diagrams using SAS. He also had a guy who could bring food.
Lu Zhou could not help but feel emotional.
I guess I still need an assistant …
"… Can you do it or not?" Brother Qian's tone was full of doubt.
He did not doubt Lu Zhou's ability in the field of mathematics. After all, the person who proved Zhou's conjecture was a big name.
However, the strength in the field of mathematics could not be directly equivalent to the scientific research ability in other fields. Many people spent their entire lives in pure mathematics research, and their mathematical foundation was perfect. However, their lifetime achievements were only in the pure mathematics field.
Although this was not a big deal, after all, everyone had their own specialties. Not everyone was an application talent.
However, at this critical juncture, he did not want to see Lu Zhou suddenly drop the ball.
Lu Zhou smirked, "Haha, you'll know in two days whether I can do it or not."
"…"
This "haha" was very intelligent.
Although Brother Qian was suspicious, he did not say anything.
He had already waited for three days. What more could he wait for two more days?
The only thing that made him and Professor Lee Yong-eun feel uneasy was that the University of Zhi had been quiet recently. It was as if they were preparing for a big move. The two sides had a lot of overlap in the "carbon nanotube modified cement-based composite" research project. Even the base material of the project was Portland cement.
This made people panic.
Especially since their project was in a bottleneck …
Lu Zhou hung up the phone and walked into the cafeteria. Not long after he put his phone back into his pocket, he suddenly received another call.
He took out his phone and saw that it was Fat Wu.
Lu Zhou picked up the phone and swiped his food card on the barbecue rice window. He yawned and spoke.
"Hello?"
Fat Wu: "What have you been up to? I haven't seen you for a few days. "
Lu Zhou thought for a bit and said, "The physics department's research project is related to carbon nanotube materials."
Fat Wu: "Wow, carbon nanotube materials research institute? Amazing! "
Lu Zhou asked with surprise, "You know about it?"
Fat Wu smiled and said, "Didn't they relocate the laboratory last year? I brought people to install the broadband and routers there. "
Lu Zhou: "…"
Fat Wu coughed and said, "I plan on gathering people for a meeting tomorrow afternoon to discuss the promotion plan for the new version. Do you have time to come?"
"No time, I've been too busy these past few days." Lu Zhou put his food card back into his pocket and took the food plate from the cafeteria lady. He said, "How about … you organize the meeting yourself?"
Fat Wu said, "Boss, you're not going to do this right from the start, right?"
Lu Zhou also felt like this wasn't a good idea, but he didn't have time. He coughed and said, "This is a stage for you. Not to mention, even if I go, I probably won't be able to give any good suggestions. Good luck! I believe in you, future general manager! "
Fat Wu: "…?"
There was nothing wrong with it. He also thought that he was qualified to be a general manager.
However, Lu Zhou's last few words …
Why do I feel like I've seen them before?
…
Time flew by quickly.
Another two days passed by in the blink of an eye.
Lu Zhou looked at the stack of draft papers piled up in the corner of the table. He was sitting in the empty classroom. He was filled with emotions.
It was already one o 'clock in the morning.
After the library was closed, he found an empty classroom with his computer bag and worked hard for a few hours before he finally completed the final steps.
He was probably the only one who knew how much effort he had put into this project.
Lu Zhou entered a few sets of data into the computer. With the powerful computing power of the computer, he completed the final blow to the enemy.
Then, he imported the data into the formula …
Suddenly, Lu Zhou stared at the draft paper and stopped writing.
He looked at the numbers on the draft paper and looked at the numbers on the computer screen. He had a strange expression on his face.
Α = 0?
This is impossible!
No, wait …
Think about it from another angle.
If his calculations were correct, the final α parameter was indeed equal to 0.
This also meant …
When the CNTs material was mixed into the Portland cement, it did not affect the hydration reaction at all!
What the hell …
