Chapter 77: Data won't lie
Wang Wei stopped his movements and got up to come to Xu Qingzhou's side.
"Starting from the 15th sample, a small amount of Hafnium (Hf) and Zirconium (Zr) were added." Xu Qingzhou said while plugging the hard drive into the computer.
Wang Wei nodded and said: "We have experimented. Adding these two elements is conducive to the high-alloy anti-molten alkali metal corrosion performance. The facts are just as we expected. In subsequent tests, the sample data in all aspects have been improved."
"Last night, I used the model to simulate the data and found that starting from the 83rd sample, the subsequent experimental data were already unscientific. The magnetic field fluctuated hugely. By the 100th sample, the value of N was already 0."
Saying this, Xu Qingzhou performed data simulation until a strange value finally appeared, "I think it is precisely because the addition ratio of the two elements Hafnium and Zirconium changed that led to this situation."
"This situation won't happen. The magnetic induction intensity of Hafnium and Zirconium is very small, about 10^-6 Gauss, especially Zirconium, which even has a small magnetic hysteresis loop!" Wang Wei's tone was very firm.
"By the 34th sample, the content of gas interstitial elements was already relatively high." Xu Qingzhou pointed to the organizational structure diagram on the screen.
"Yes, but according to our tests, even by the 53rd sample tested now, the uniformity of the sample composition is between 4-1.5wt%, tending to be stable, completely within the acceptable range."
"But according to the simulation data of the model, even the 98th sample might have an N output value of 0."
Read! {
Wang Wei said: "From the perspective of materials science, Hafnium (Hf) and Zirconium (Zr) both have non-magnetic characteristics. The latest VAR smelting process technology for niobium-titanium alloys published by PMS also added these two elements."
"According to the junior's model, our path is wrong. Starting from the 65th sample, including the subsequent experiments, we are all doing useless work."
"Impossible! Yes, this model is not perfect, and the simulated values will have errors, but the main framework is accurate, which means the general direction will not have problems. The simulation result is that the data after the 100th sample all have abnormalities. Data won't lie."
After despising the person on the chair, his footsteps paused, "Do you have any arrangements tomorrow?"
Song Yao wore a newly bought white sweatshirt, standing tall and straight, making passersby look sideways, even girls were no exception. Facts proved that girls indeed like to look at beauties too.
"Very busy during this time." Xu Qingzhou could feel the resentment across the phone.
Xu Qingzhou nodded. He slept until after three last night and got up early today, "I'll go back and make up for sleep first."
Besides improving the mathematical model, Xu Qingzhou also borrowed two math books, one "Modern Mathematical Physics Methods" and one "Higher Mathematics Theory". The current courses are not difficult for Xu Qingzhou, just like the advanced algebra class in the morning.
On the balcony, Song Yao snorted coldly, suddenly a bit understanding her mother's helplessness. Her father always said he was very busy. She pouted: "Is it so busy that there is no time to eat together?"
"Could it be that your model is wrong?" Wang Wei still didn't believe that the experiment done for so long was almost half wrong.
It's been a week, and she is still so good-looking.
Song Yao thought about the business, and didn't struggle with the clothes anymore, saying: "Sichuan cuisine, I've been here for more than half a month, and I miss the food in Rongcheng a bit."
Phew, cheap.
Xu Qingzhou went to find Song Yao after the last class on Friday afternoon.
Gong Yunfei was also attracted by the two of them.
Wang Wei left with the model and data.
In the evening, it started to drizzle. Although the rain stopped, the air carried the scent of moist soil. When the wind blew, it was still a bit cold.
Seeing that Xu Qingzhou didn't wear the clothes bought last time, Song Yao was a bit unhappy, "It's cold, and you wear so little. If you don't freeze, who will?"
Heh, why should he come out when he says so.
"Junior, have you not rested well these days?" Seeing Xu Qingzhou had two dark circles, Gong Yunfei asked with a smile.
"Model optimization work is left to me," Xu Qingzhou nodded.
Xu Qingzhou was very confident in the model. He had verified it several times yesterday. Gong Yunfei added on the side: "But it didn't clearly state how much element was added..."
He plans to read some extracurricular books during class.
After saying this, Song Yao was stunned again. This sentence was also very familiar. How did she become a bit like a resentful woman?
The girl leaned on the balcony, the breeze blew, lifting a few strands of fine hair in front of her forehead, lazily spitting out two words: "Not going."
Xu Qingzhou felt like he was being checked, nodded and answered: "Right, just came out of the library, preparing to return to the dormitory." Song Yao's tone was dissatisfied: "Xu Qingzhou, if I don't look for you, you won't look for me, right?"
The voice on the phone pulled Song Yao back.
Xu Qingzhou looked around and said with a smile: "The temperature has dropped quite a bit. It's a bit cold at night now."
Ten minutes later, Wang Wei let out a long breath, turned to look at Xu Qingzhou, and said: "Junior, I need a few days to verify."
In the afternoon, after finishing the English class in Building 3, Xu Qingzhou continued to soak in the library.
Wang Wei stared at the model, his face a bit ugly, not because of Xu Qingzhou's rebuttal, but because if it was really wrong, it meant they wasted a lot of time.
Saying goodbye to Gong Yunfei and the others, Xu Qingzhou went straight back to the dormitory. There was no one in the dormitory. I don't know what they were busy with. He set an alarm for 13:40 and went to bed directly.
"Eat what?" Xu Qingzhou was puzzled why this person had such great resentment, could it be that her relative came? But her relative didn't come at the beginning of the month.
"No." Song Yao's voice was still lazy, "How about this, give you a chance, you beg me, and I'll go."
He had just replied to the message when his phone vibrated. It was a call from Song Yao.
At 11:00 PM, Xu Qingzhou packed his things and came out of the School of Mathematics library, replying to Song Yao. At 10:50, she sent a message asking if he had finished.
!.
"Xu Qingzhou, do you have any bottom line?"
Xu Qingzhou didn't interrupt. He knew very little about materials, listening quietly to the two discussing.
Doing scientific research is like this, 1 is 1, 2 is 2, the more you argue, the clearer it becomes.
"You are still in the library so late?" A clear and cool voice came from the receiver.
"Eat together tomorrow night?"
Xu Qingzhou was passing by the small lake at this time. The people hugging and biting each other on the chairs had changed a batch.
"Beg you."
"This time can be no."
However, in Song Yao's crystal-clear eyes, there was always a touch of quietness, and her body exuded a feeling of keeping people thousands of miles away.
"Here... Sichuan cuisine is not that authentic?" Xu Qingzhou recalled.
Song Yao frowned: "Have you eaten there? With whom?"
"Is this the point?" Xu Qingzhou was a bit speechless: "Isn't this very normal? When in Rome, do as the Romans do. Sichuan cuisine will have many changes when it arrives here. This time forget it. If you want to eat something more authentic, I will take you when I have time."
Song Yao heard that Xu Qingzhou was going to take her, and felt much warmer in her heart, but ignored the topic of who she ate with.
