Chapter 77 Data Don’t Lie
Wang Wei stopped what he was doing, stood up and came to Xu Qingzhou’s side.
"Starting from sample No. 15, a small amount of hafnium (Hf) and zirconium (Zr) have been added." Xu Qingzhou said while plugging the hard drive into the computer.
Wang Wei nodded and said: "We have experimented and found that adding these two elements is beneficial to the corrosion resistance of high alloys to molten alkali metals. The fact is as we expected. In subsequent tests, all data of the samples have promoted.”
"Last night, I simulated the data with a model and found that starting from sample No. 83, the subsequent experimental data was no longer scientific. The magnetic field fluctuated hugely. By the time of sample No. 100, the value of n was already 0."
As he spoke, Xu Qingzhou simulated the data until a strange value appeared at the end, "I think it is precisely because of the change in the addition ratio of the two elements hafnium and zirconium that caused this situation."
"This will not happen. The magnetic induction intensity of hafnium and zirconium is very small, about 10^-6 Gauss. Zirconium, in particular, even has a tiny hysteresis loop!" Wang Wei said with certainty.
"By sample No. 34, the element content in the gas gap is already relatively high." Xu Qingzhou pointed to the organizational structure diagram on the screen.
"Yes, but after our testing, even with the current sample No. 53, the composition uniformity of the sample is between 4-1.5wt%, which tends to be stable and is completely within the acceptable range."
"But according to the simulation data of the model, even sample No. 98 may have an output value of n of 0."
"Is there something wrong with your model?" Wang Wei still didn't believe that after doing experiments for so long, almost half of them were wrong.
"Impossible! Yes, this model is not perfect, and there will be errors in the simulated values. However, the main frame is accurate, which means that there will be no problems in the general direction. The simulation results are that the data after sample No. 100 have Exception, the data doesn’t lie.”
Xu Qingzhou is very confident in the model. He checked it several times yesterday.
Gong Yunfei was also attracted to them.
"According to junior brother's model, we are on the wrong path. Starting with Sample No. 65, including the subsequent experiments, we are doing useless work."
Wang Wei stared at the model with an ugly look on his face, not because of Xu Qingzhou's rebuttal, but because if it was really wrong, it meant they wasted a lot of time.
This is what scientific research is like, 1 is 1, 2 is 2, and the more you debate, the clearer it becomes.
Wang Weidao: "From a material science perspective, both hafnium (Hf) and zirconium (Zr) have non-magnetic properties. These two elements are also added to the latest niobium-titanium alloy VAR smelting process technology published by PMS."
Gong Yunfei added next to him: "But it didn't clearly state how many elements were added."
Xu Qingzhou did not interrupt. He knew very little about the materials and listened quietly to the discussion between the two.
Ten minutes later, Wang Wei took a long breath, turned to look at Xu Qingzhou, and said, "Junior brother, I need a few days to verify it."
"Leave the work of model optimization to me," Xu Qingzhou nodded.
Wang Wei left with the model and data.
"Junior brother, have you not had a good rest these days?" Seeing Xu Qingzhou's two dark circles, Gong Yunfei asked with a smile.
Xu Qingzhou nodded. He went to bed at around three o'clock last night and got up early today. "I'll go back and catch up on my sleep first."
After saying goodbye to Gong Yunfei and the others, Xu Qingzhou went directly back to the dormitory. There was no one in the dormitory and he didn't know what they were busy with. He set an alarm clock for 13:40 and went to bed directly.
In the afternoon, after finishing his English class at No. 3 Teacher, Xu Qingzhou continued to visit the library.
In addition to improving the mathematical model, Xu Qingzhou also borrowed two mathematics books, one "Modern Mathematical Physics Methods" and one "Advanced Mathematical Theory". The current courses are not difficult for Xu Qingzhou, such as the advanced substitute class in the morning.
He planned to read some extracurricular books during class.
At 11 o'clock in the evening, Xu Qingzhou packed up his things and came out of the library of Shuyuan to send a message to Song Yao. At 10:50, she sent a message asking him if he was over.
As soon as he finished replying to the message, his phone vibrated. It was a call from Song Yao.
"Are you still in the library so late?" A cool voice came from the receiver. Xu Qingzhou felt like he was being checked, and nodded and replied: "Yes, I just came out of the library and am going back to the dormitory."
Song Yao said in a dissatisfied tone: "Xu Qingzhou, if I don't look for you, you won't look for me."
"I'm very busy during this period." Xu Qingzhou could feel the sadness through his mobile phone.
On the balcony, Song Yao snorted coldly, suddenly understanding her mother's helplessness. Her father always said he was very busy, and she curled her lips: "Are you so busy that you don't even have time to eat together?"
After saying this, Song Yao was startled again. This sentence seemed so familiar. Why did she become a bit like a resentful woman?
"Let's have dinner together tomorrow night?"
The voice on the phone pulled Song Yao back.
The girl leaned on the balcony, the breeze blew by, raising a few strands of hair on her forehead, and lazily uttered two words: "I won't go."
Hehe, why did he come out just as soon as he said it?
Xu Qingzhou was passing by the small lake at this time, hugging each other and eating each other on the chairs, and another group of people changed.
Bah, vile.
After scorning the person on the chair, he paused and asked, "Do you have any plans for tomorrow?"
"No." Song Yao's voice was still lazy, "Let's give you a chance. If you beg me, I will go."
"Please."
"Xu Qingzhou, do you have any bottom line?"
"It doesn't matter at this time."
Xu Qingzhou went to find Song Yao after the last class on Friday afternoon.
In the evening, it started to rain continuously. Although the rain stopped, there was a moist earthy smell in the air, and the wind was still a little cold.
Song Yao is very beautiful. She is wearing a newly bought white sweater with exquisite collarbones and bulging chest. When paired with high-waisted jeans, she looks very tall.
However, there was a sense of tranquility and serenity in his crystal eyes that made people feel that they were thousands of miles away.
I haven’t seen her for a week, but she is still so beautiful. Xu Qingzhou clicked his tongue and sighed, "The temperature has dropped sharply."
Seeing that Xu Qingzhou didn't wear the clothes he bought last time, Song Yao was a little unhappy, "On a cold day, you only wear this much. If you don't freeze, who will you freeze?"
"What to eat?" Xu Qingzhou wondered why this person had so much resentment. Could it be that relatives were here? But didn’t her relatives come at the beginning of the month?
Song Yao thought about business and went back without worrying about her clothes. She said, "Sichuan cuisine, I have been here for more than half a month and I miss the food in Chengdu."
"The Sichuan food here is not that authentic?" Xu Qingzhou recalled.
Song Yao frowned slightly: "Have you ever eaten there? With whom?"
"Is this the point?" Xu Qingzhou was a little speechless: "Isn't this normal? When you go to the country, do as the Romans do. Sichuan cuisine will also change a lot when you get here. Forget it this time. If you want to eat something more authentic, I will take you there when I have time. "
Song Yao felt a lot warmer when she heard that Xu Qingzhou was taking her there, but she ignored the topic of who to eat with.
