After reading papers all day, it wasn't until Liu Rui started snoring that Lu Zhou climbed into bed and fell asleep.
Looking at the pile of data, Lu Zhou felt his scalp numb.
Lu Zhou generally understood, but he had no better way.
The next day, I got up early.
After receiving the mission from Senior Brother Qian, Lu Zhou went to the library.
"Then what's the problem?" Lu Zhou asked confused, "I mean... Now that we know the reason for the unsatisfactory tensile strength of sample No. 2, can't we just solve it?"
Senior Brother Qian: "In order to find a solution, we have done many sets of experiments. Although the budget is still sufficient, it will be no problem to do a few more sets. But a few days ago we learned that the materials science laboratory at Zhejiang University We may have made breakthrough progress on this project, and time no longer allows us to continue delaying it.”
He still sat there in that posture, not moving a word.
"The sooner the better. Although I can't wait... but it's best within three days." Senior Brother Qian thought for a while and continued, "After three days, no matter whether there is any result or not, I hope you can at least give me Report on the progress."
Looking at the pile of data, Lu Zhou felt his scalp numb.
After stopping by the cafeteria and buying two steamed buns, Lu Zhou arrived at the laboratory on time.
After Lu Zhou thought for a moment, he said seriously: "I can't guarantee success, but I can try... When will you expect the results?"
Lu Zhou generally understood, but he had no better way.
Lu Zhou, who was watching from the side, asked: "What is the specific problem?"
When he arrived, Senior Brother Liu and Senior Brother Qian were already gathered around the instrument and started working.
In contrast, Lu Zhou still prefers places like libraries.
However…
Looking at Lu Zhou who was deep in thought with a smile, Old Tang nodded in his mind.
When he arrived, Senior Brother Liu and Senior Brother Qian were already gathered around the instrument and started working.
Although Senior Brother Liu made a desk for him, the laboratory was too deserted and the learning atmosphere was not strong enough.
Ten minutes passed.
…
What we need to do today is to use a Fourier transform infrared spectrometer to draw the FTIR spectrum of each sample and record the absorption peaks of each functional group and chemical bond in the early hydration reaction of the carbon nanotube modified sample.
After listening to Professor Tang's words, a thoughtful expression appeared on Lu Zhou's face.
"Correct, but not accurate," Senior Brother Qian nodded approvingly, pointed out a few places on the FTIR image, and continued, "Sample No. 2 is a cement sample mixed with CNTs. According to the mechanical properties, According to the results, our 2 samples performed quite well in the compressive capacity test, but their performance in the tensile capacity test was unsatisfactory. Based on the characteristic peak data at 6-10h age on the FTIR image, our preliminary judgment is that The CNTs material hinders the polymerization process of silicon-oxygen tetrahedrons in the CSH gel, leading to the formation of pores inside the cement material in the later stages of the hydration reaction."
Recall what Senior Brother Qian said.
"We need an expert who is proficient in mathematics, preferably functional analysis, to help us analyze these experimental data to see if we can find some valuable clues. It is best to help us find the early effects of CNTs materials on Portland cement. What is the impact of age hydration reaction... I have taught myself functional analysis, but I still have no clue about these data. As expected, when it comes to such difficult calculations, I still have to entrust you experts from the Mathematics Institute. "
"... Our research is mainly aimed at enhancing the solubility of carbon nanotubes in Portland cement, while improving the bonding force between carbon nanotubes and matrix materials." While conducting experiments, Senior Brother Qian introduced to Lu Zhou, " However, the progress of the research is not optimistic. Professor Li should have told you that we have encountered a bottleneck."

Frowning his brows slightly, Lu Zhou pondered for a while, but then quickly shook his head: "It's completely different. The reason why aerospace problems can be transformed into mathematical problems in the final analysis is because it is still a problem of particle motion in the final analysis, and it can rely on the formula and readily available data… ”
Lu Zhou found an empty seat in the library and sat down. He picked up the pen and tapped lightly on the draft paper, ready to start writing.

Passing by the printing room next to the library, Lu Zhou turned around and printed out all the papers and experimental data he wanted to read on A4 paper.
Lu Zhou, who was watching from the side, asked: "What is the specific problem?"
Lu Zhou found an empty seat in the library and sat down. He picked up the pen and tapped lightly on the draft paper, ready to start writing.
He still sat there in that posture, not moving a word.

But a few days ago we learned that the materials science laboratory at Zhejiang University We may have made breakthrough progress on this project, and time no longer allows us to continue delaying it.”
"It's not as simple as you said," Brother Qian said expressionlessly, "We have tried many methods, including using melamine as a nitrogen precursor regardless of production costs, and ball milling carbon nanotubes under vacuum conditions. The surface of carbon nanotubes is functionally modified...but judging from the tensile test data of samples No. 27 and No. 28, the results are also very bad."
People are iron rice is steel.
Just like the mathematics department at the undergraduate level does not offer the course of materials physics, the applied physics major does not offer the course of functional analysis. After all, there are only a small number of people who have obtained a double degree at the undergraduate level. Most people only selectively study courses they have not taken by themselves according to the needs of their own research direction after being admitted to graduate school.
After stopping by the cafeteria and buying two steamed buns, Lu Zhou arrived at the laboratory on time.
After receiving the mission from Senior Brother Qian, Lu Zhou went to the library.
"The problem lies here. Look at the data we measured through the Fourier transform infrared analyzer." Senior Brother Qian pointed to the FTIR image just printed out and continued, "What did you see?"
Ten minutes passed.
"Is the characteristic peak of No. 2 cement sample abnormal?" Lu Zhou said in an uncertain tone.
Lu Zhou nodded and said, "I'll try my best."
Frowning his brows slightly, Lu Zhou pondered for a while, but then quickly shook his head: "It's completely different.

Resisting the urge to waste points, Lu Zhou stared at the still warm A4 paper for a long time. Suddenly he recalled what he had learned when reading the paper yesterday. His heart moved slightly. Sure enough, he could see it from the drawing. Something a little wrong.
emmmm…
Sitting in the library until twelve o'clock, Lu Zhou looked at the untouched draft paper, thought to himself MMP, threw the pen on the table, got up and walked to the cafeteria.
What we need to do today is to use a Fourier transform infrared spectrometer to draw the FTIR spectrum of each sample and record the absorption peaks of each functional group and chemical bond in the early hydration reaction of the carbon nanotube modified sample.

At this time, he suddenly realized that this job was not as simple as it seemed.
"It's okay if you find it difficult," Professor Tang said with a smile, "Mathematics is a scientific research tool, and you are studying applied mathematics. There will be many opportunities to encounter similar projects in the future."
If there is a fixed formula that can be used, or even a clear goal, he can easily figure out where to start. But the current situation is that the scientific research dogs at the Institute of Physics have not even found the problem, so they ask him, a math person, to help them find bugs.

Sitting among a group of people who are busy writing, even if they want to be distracted, they will not be able to hold back the sense of urgency and guilt in their hearts and focus on studying.
After reading papers all day, it wasn't until Liu Rui started snoring that Lu Zhou climbed into bed and fell asleep.

It's really just a matter of passing the buck...
"The problem lies here. Look at the data we measured through the Fourier transform infrared analyzer." Senior Brother Qian pointed to the FTIR image just printed out and continued, "What did you see?"
…
While serving food in the cafeteria, Lu Zhou happened to bump into Old Tang, so he walked up with a plate, said hello, and sat across from him.
Resisting the urge to waste points, Lu Zhou stared at the still warm A4 paper for a long time. Suddenly he recalled what he had learned when reading the paper yesterday. His heart moved slightly. Sure enough, he could see it from the drawing. Something a little wrong.

Even if you are a top student, you still have to eat.

For mathematics, they are essentially the same. Anything that exists. There is data hidden in the depths that can be mined, laws that can be calculated, and mathematical models that can be built.

Sitting in the library until twelve o'clock, Lu Zhou looked at the untouched draft paper, thought to himself MMP, threw the pen on the table, got up and walked to the cafeteria.
If there is a fixed formula that can be used, or even a clear goal, he can easily figure out where to start. But the current situation is that the scientific research dogs at the Institute of Physics have not even found the problem, so they ask him, a math person, to help them find bugs.
"Actually, they are the same." Old Tang shook his head, "Whether it is the movement of the spacecraft, the movement of particles, or the changes in functional groups... For mathematics, they are essentially the same. Anything that exists. There is data hidden in the depths that can be mined, laws that can be calculated, and mathematical models that can be built. You can’t find it just because you haven’t put enough effort into it. Think more and observe more, and I believe you will be able to find it. There are clues in it.”
This place more or less reminded him of the feeling of being highly concentrated.
emmmm…
What we need to do today is to use a Fourier transform infrared spectrometer to draw the FTIR spectrum of each sample and record the absorption peaks of each functional group and chemical bond in the early hydration reaction of the carbon nanotube modified sample.
After a pause, Senior Brother Qian sighed and continued.
Even if you are a top student, you still have to eat.
However…
Recall what Senior Brother Qian said.
Ten minutes passed.
He still sat there in that posture, not moving a word.
"It's not as simple as you said," Brother Qian said expressionlessly, "We have tried many methods, including using melamine as a nitrogen precursor regardless of production costs, and ball milling carbon nanotubes under vacuum conditions. The surface of carbon nanotubes is functionally modified...but judging from the tensile test data of samples No. 27 and No. 28, the results are also very bad."
After looking at Lu Zhou, Old Tang smiled and asked, "How do you feel?"
It's really just a matter of passing the buck...
…

Looking at the pile of data, Lu Zhou felt his scalp numb.
The next day, I got up early.
Looking at Lu Zhou who was deep in thought with a smile, Old Tang nodded in his mind.
If there is a fixed formula that can be used, or even a clear goal, he can easily figure out where to start. But the current situation is that the scientific research dogs at the Institute of Physics have not even found the problem, so they ask him, a math person, to help them find bugs.
Just like the mathematics department at the undergraduate level does not offer the course of materials physics, the applied physics major does not offer the course of functional analysis. After all, there are only a small number of people who have obtained a double degree at the undergraduate level. Most people only selectively study courses they have not taken by themselves according to the needs of their own research direction after being admitted to graduate school.
"It's not as simple as you said," Brother Qian said expressionlessly, "We have tried many methods, including using melamine as a nitrogen precursor regardless of production costs, and ball milling carbon nanotubes under vacuum conditions. The surface of carbon nanotubes is functionally modified...but judging from the tensile test data of samples No. 27 and No. 28, the results are also very bad."
At this time, he suddenly realized that this job was not as simple as it seemed.
Resisting the urge to waste points, Lu Zhou stared at the still warm A4 paper for a long time. Suddenly he recalled what he had learned when reading the paper yesterday. His heart moved slightly. Sure enough, he could see it from the drawing. Something a little wrong.
It was his habit to study complex mathematical problems by spreading out everything he needed on the table.

emmmm…
After reading papers all day, it wasn't until Liu Rui started snoring that Lu Zhou climbed into bed and fell asleep.
"The sooner the better. Although I can't wait... but it's best within three days." Senior Brother Qian thought for a while and continued, "After three days, no matter whether there is any result or not, I hope you can at least give me Report on the progress."
Even if you are a top student, you still have to eat.
After stopping by the cafeteria and buying two steamed buns, Lu Zhou arrived at the laboratory on time.
Looking at the pile of data, Lu Zhou felt his scalp numb.
People are iron rice is steel.
"Professor, could you please stop attacking me and give me some ideas?" Lu Zhou sighed.
In contrast, Lu Zhou still prefers places like libraries.
Senior Brother Qian: "In order to find a solution, we have done many sets of experiments. Although the budget is still sufficient, it will be no problem to do a few more sets. But a few days ago we learned that the materials science laboratory at Zhejiang University We may have made breakthrough progress on this project, and time no longer allows us to continue delaying it.”
Lu Zhou looked a little unhappy and felt troubled.
Lu Zhou generally understood, but he had no better way.
Even if you are a top student, you still have to eat.
"The problem lies here. Look at the data we measured through the Fourier transform infrared analyzer." Senior Brother Qian pointed to the FTIR image just printed out and continued, "What did you see?"
"We need an expert who is proficient in mathematics, preferably functional analysis, to help us analyze these experimental data to see if we can find some valuable clues. It is best to help us find the early effects of CNTs materials on Portland cement. What is the impact of age hydration reaction... I have taught myself functional analysis, but I still have no clue about these data. As expected, when it comes to such difficult calculations, I still have to entrust you experts from the Mathematics Institute. "
"Correct, but not accurate," Senior Brother Qian nodded approvingly, pointed out a few places on the FTIR image, and continued, "Sample No. 2 is a cement sample mixed with CNTs. According to the mechanical properties, According to the results, our 2 samples performed quite well in the compressive capacity test, but their performance in the tensile capacity test was unsatisfactory. Based on the characteristic peak data at 6-10h age on the FTIR image, our preliminary judgment is that The CNTs material hinders the polymerization process of silicon-oxygen tetrahedrons in the CSH gel, leading to the formation of pores inside the cement material in the later stages of the hydration reaction."
Sitting in the library until twelve o'clock, Lu Zhou looked at the untouched draft paper, thought to himself MMP, threw the pen on the table, got up and walked to the cafeteria.
Ten minutes passed.
"... Our research is mainly aimed at enhancing the solubility of carbon nanotubes in Portland cement, while improving the bonding force between carbon nanotubes and matrix materials." While conducting experiments, Senior Brother Qian introduced to Lu Zhou, " However, the progress of the research is not optimistic. Professor Li should have told you that we have encountered a bottleneck."
Resisting the urge to waste points, Lu Zhou stared at the still warm A4 paper for a long time. Suddenly he recalled what he had learned when reading the paper yesterday. His heart moved slightly. Sure enough, he could see it from the drawing. Something a little wrong.
After looking at Lu Zhou, Old Tang smiled and asked, "How do you feel?"
Lu Zhou, who was watching from the side, asked: "What is the specific problem?"
Lu Zhou nodded and said, "I'll try my best."
While serving food in the cafeteria, Lu Zhou happened to bump into Old Tang, so he walked up with a plate, said hello, and sat across from him.
"Then what's the problem?" Lu Zhou asked confused, "I mean... Now that we know the reason for the unsatisfactory tensile strength of sample No. 2, can't we just solve it?"
…
Ten minutes passed.
"Actually, they are the same." Old Tang shook his head, "Whether it is the movement of the spacecraft, the movement of particles, or the changes in functional groups... For mathematics, they are essentially the same. Anything that exists. There is data hidden in the depths that can be mined, laws that can be calculated, and mathematical models that can be built.

After looking at Lu Zhou, Old Tang smiled and asked, "How do you feel?"
"It's very difficult! Much more difficult than pure mathematics problems." Lu Zhou sighed.

After receiving the mission from Senior Brother Qian, Lu Zhou went to the library.

Anyway, it can be reimbursed as research funds, and he does not need to spend his own money.
"It's okay if you find it difficult," Professor Tang said with a smile, "Mathematics is a scientific research tool, and you are studying applied mathematics. There will be many opportunities to encounter similar projects in the future."
When he arrived, Senior Brother Liu and Senior Brother Qian were already gathered around the instrument and started working.
"... Our research is mainly aimed at enhancing the solubility of carbon nanotubes in Portland cement, while improving the bonding force between carbon nanotubes and matrix materials." While conducting experiments, Senior Brother Qian introduced to Lu Zhou, " However, the progress of the research is not optimistic.

Sitting among a group of people who are busy writing, even if they want to be distracted, they will not be able to hold back the sense of urgency and guilt in their hearts and focus on studying.
"I can't give you the ideas. You have to find this by yourself, but I can give you some suggestions," Professor Tang smiled and continued, "Didn't you participate in a mathematical modeling competition? Recall that time a feeling of."
"It's very difficult! Much more difficult than pure mathematics problems." Lu Zhou sighed.
Lu Zhou nodded and said, "I'll try my best."
It was his habit to study complex mathematical problems by spreading out everything he needed on the table.
Children can be taught.
After Lu Zhou thought for a moment, he said seriously: "I can't guarantee success, but I can try... When will you expect the results?"
He still sat there in that posture, not moving a word.
He still sat there in that posture, not moving a word.
Frowning his brows slightly, Lu Zhou pondered for a while, but then quickly shook his head: "It's completely different. The reason why aerospace problems can be transformed into mathematical problems in the final analysis is because it is still a problem of particle motion in the final analysis, and it can rely on the formula and readily available data… ”
The next day, I got up early.
