Chapter 288: Do You Have a Habit of Not Being Able to Live Without Tormenting People?

This year is different from previous years; the Mid-Autumn Festival only had Saturday and Sunday off, and Xu Qingzhou and Song Yao were basically at home.

28th, Monday.

Song Yao went to talk to Li Jiaoshou Daiyue about the class exemption application, and Xu Qingzhou stayed at home to perfect the experimental model of Professor Zhao Shengwen and the others.

After such a long accumulation, there is already a complete multi-physics coupling model that can effectively describe the interaction between multiple physical fields such as electrochemistry, thermal science, and mechanics.

Xu Qingzhou opened the folder and discovered that in the month he went to Switzerland, Professor Zhao and the others had made some new attempts.

For example, using coal-based kaolin, utilizing chemical etching, and then preparing porous silicon nanomaterials through magnesiothermic reduction in an Ar atmosphere.

"The effect is not bad."

Xu Qingzhou couldn't help but lift his hand and hook her chin.

Read! {

Auntie Jia had a complex expression, thinking to herself that this young couple, don't look at them as usually serious, they play quite wildly.

"This—"

This senior brother is working on an acoustic levitation project; after calculation by the boundary element method and then checking with the finite element method, he discovered that if designed reasonably, the instrument can float itself in the air and also has quite high fault tolerance.

Cao Jingyu chuckled and said: "I have seen this child's grades and test papers; they are indeed quite good. She is dating that Xu Qingzhou from the School of Mathematics, right?"

September 30th.

"I'm just on my period, not pregnant, and certainly not disabled, so I don't have to lie down all the time." Song Yao snorted and said.

There are also experimental materials related to lithium dendrites.

Song Yao was wrapped in a bathrobe, her hair already slept into a mess, sloppily hanging on her shoulders, coming out of the bedroom with sleepy eyes.

"Mm, I tested it personally; this girl's level is at least up to senior year."

"..."

In the sunlight, the broken hair in front of her temples shone brightly; the sun shone from the side, and her long eyelashes left several silhouettes on her clean face. She didn't wear makeup today, and a kind of broken beauty appeared on her beautiful face.

Xu Qingzhou smiled and nodded; going out for a walk is also quite good.

In the office, only the Dean of the School of Economics, Cao Jingyu, was there.

Pah~ even this can be thought of in a lewd way.

Seeing Er Miao squatting eagerly in front of the feeder, he smiled and stood up.

Intersection, waiting for the red light.

Just at this moment, a familiar voice sounded behind the two.

Er Miao was very cooperative.

"You know too?" Li Daiyue was puzzled.

The old men and old ladies were buying groceries, doing morning exercises, and some were already strolling in the residential area; there were quite a lot of people, just not many young faces.

At the table, it was covered with sheets of draft paper filled with calculations.

The numerical values are outrageous, and there is currently no solution idea.

Song Yao complained in her heart.

Song Yao let Xu Qingzhou hold her hand, really liking this feeling of only needing to follow and not needing to think about anything, especially at this time.

"Little Xu, little Song, you two, going out?"

Xu Qingzhou's work now is not particularly difficult; it's just using the latest data to perform iterative processing on the model.

Xu Qingzhou turned his head to look at the girl beside him.

In the past, I often heard people say: "The value of a postgraduate student does not lie in how much knowledge you have learned, but in how much knowledge you have created; no matter how much you learn, at best you are a library, and the outside world's evaluation of you will only be based on your work."

"Good."

Thinking, Xu Qingzhou glanced at the draft paper on the table; the only thing that is more troublesome is the Polignac conjecture.

Doing calculations, sometimes it really is like DOI; if you don't get it out, it's uncomfortable to hold it in.

Moreover, just now the voice was full of energy, and the stubborn girl had already plunged into his arms.

Xu Qingzhou quite agreed.

"Director Cao."

After sighing, Xu Qingzhou turned back to the sofa and pulled a stack of materials from the sofa armrest.

On the day before the National Day holiday, Xu Qingzhou sent the battery analysis results to Professor Zhao; for example, in the D group samples, sequentially adding phenolic resin and graphene oxide to prepare precursor gel, then obtaining the precursor through freeze-drying and high-temperature carbonization... the silicon-carbon composite material prepared according to this step is the best.

Song Yao took the printed application form to find Li Jiaoshou.

"Vibrant old people and lifeless young people."

Looking at the two people holding hands, Auntie Jia was stunned for a moment; how come after not seeing them for half a year, the state of these two children had completely changed.

"Can't help it, the school beauty Song's delicate appearance is too endearing... Hiss~ won't say anymore."

The graduation thesis can be finished by the end of this month, and the defense can be conducted; as for the supervisor, he now tends more towards Academician Chu Jiangfeng.

"There's something on your face." Xu Qingzhou withdrew his hand and made up a story.

"Class exemption application?"

Besides this, the research group also used commercial Al-Si alloy to chemically etch with alkali to prepare nanoporous silicon materials.

Song Yao pouted, too lazy to bother with this person, planning to wait until these few days pass, then take revenge.

Watching Er Miao enjoy breakfast with a crunch, Xu Qingzhou took a cup of hot water, stood by the window breathing fresh air, and thought about the next things in his head.

There is no time to do experiments by himself now, so he can only look at the materials first and accumulate some experience; after all, batteries are a research hotspot for a considerable period in the future.

Thus, the first day of the holiday was spent rotting away.

"Auntie Jia."

Last night, under the school beauty Song's gaze, he honestly went to sleep at 12 o'clock.

Feet and hands, this guy doesn't have any normal hobbies.

Song Yao's hands are very good-looking, fingers slender and long, white and tender.

Battery performance is high, but the shortcomings are equally obvious; the preparation process is complex, and it is unlikely to be mass-produced.

Xu Qingzhou watched with great interest.

October 2nd, 8 AM.

Xu Qingzhou didn't argue; girls, after all, have those few days every month, and their mood swings are a bit big.

Xu Qingzhou and the school beauty Song are not the type of people who like to join in the fun, especially during such a big holiday, where every place is crowded; going out for a trip is less like going to play and more like going to count heads.

In the office, after getting the application form, Li Daiyue took a look, there was no problem, and then she handed Song Yao a USB flash drive.

"Hoo~"

The two crossed the road, Auntie Jia and two other aunties had already met up.

"Everyone is saying it, it's hard not to know. Moreover, last time at the big meeting, I met Old Gu from the School of Mathematics, and he was still joking with me that our School of Economics counts as the mother's family."

Of course, the most important thing is that Song Yao at this time is a bit different, gentle and soft, making people want to tease her.

When the doctoral supervisor comes over to check halfway, there is only one sentence: Very good, as for my suggestion here, how about we stop this project and directly work on UFO research? Xu Qingzhou is now encountering this kind of problem; the calculated result can refute the exponent sum and itself.

15 minutes later, the two young people appeared downstairs in the residential area.

The calculated result is completely wrong.

Data is more real than human feeling; through data, understand the internal structure of the new sample, so as to better adjust parameters and determine a higher-quality material ratio. Li Daiyue frowned and said, suddenly reacting again, she seemed to have been led into the gossip ditch, "This is Song Yao's class exemption application."

Since using the feeder and reducing the food, Er Miao is indeed a bit thinner than before; although it still looks chubby, it's best if it can lose weight; animals are the same as people, being fat is bad for the body.

6 AM, he climbed up again to continue calculating.

Looking at the data chart, Xu Qingzhou nodded.

"Endearing."

"I'll go with you."

Xu Qingzhou lowered his head, the tip of his pen lightly tapped, and he went through all the calculations just now in his mind, hoping to find a loophole.

The research groups in colleges and universities will shrink during holidays, sometimes even directly having none; fortunately, Li Jiaoshou Daiyue still gave the department a 3-day holiday.

"Why are you up?" Xu Qingzhou put down the materials.

The initial capacity is as high as 3003mAh·g^-1, and after 300 cycles under 0.3C conditions, it still maintains a capacity of 1000mAh·g^-1... In practical applications, it is basically to coat a layer of carbon on the silicon material to improve its electrical conductivity, while also increasing the material spacing and improving its electrochemical performance.

Xu Qingzhou went through all the materials first before importing the data into the model.

After all, they had been honest with each other... Song Yao hugged Xu Qingzhou, closed her eyes, and felt the temperature coming from under the boy's clothes, inexplicably having a sense of peace of mind.

Song Yao's small face stiffened, her teeth itchy: "Xu Qingzhou, do you have a habit of not being able to live without tormenting people?"

Li Daiyue discovered that besides her, it was as if the whole world knew about her prospective apprentice and Xu Qingzhou.

"Is it still endearing now?" Song Yao asked with squinted eyes, twisting half a circle on her boyfriend's waist.

In October, the breath of autumn is thicker, leaves turn from green to yellow, the road is paved with withered leaves, the air carries the fragrance of soil, and the water puddles on the asphalt road reflect the blue of the sky.

Li Daiyue gave a reading list, letting Song Yao hurry up and finish reading the books on it.

The school beauty Song's dull and silly expression made Xu Qingzhou pinch her white cheeks again by some strange chance.

Last time we met, little Xu was listless, this time it's little Song? "You two..."

"They were in the same class in high school, it should be then..."

Er Miao yawned, wandering in the living room, rubbing against Xu Qingzhou's pant legs a few times, seeing the two-legged beast didn't pay attention to it, it walked away lonely.

National Day holiday, the two of them didn't plan to go out to play.

【Under 7MPa stacking pressure, when current density is 3.0mAcm-2 and capacity is 3.0mAhcm-2, Li/Li6PS5Cl/Li】

At this point, everyone must be sleeping.

8 o'clock, the residential area was already lively.

This kind of material possesses a first discharge capacity of 3388.8mAh·g^-1 and a charge capacity of 2710.7mAh·g^-1; under 100mA·g^-1 conditions, it still provides a reversible specific capacity of 546mAh·g^-1 after 100 cycles.

Song Yao looked at the materials, Li Daiyue stood up and took the application form to go through the process.

Cat life is difficult!

"Mm, this little girl's talent is very good." Li Daiyue nodded.

Xu Qingzhou discovered that Auntie Jia's look at them was getting stranger and stranger.

"Meow~ meow~" Until Er Miao meowed twice more, worrying about disturbing Song Yao who hadn't woken up yet, he pressed the switch and released a small pinch of cat food for the greedy cat.

The automatic feeder was empty, nothing to eat.

"If you want to eat, meow twice." Xu Qingzhou hooked Er Miao's chin.

"Meow~"

Actually, sending the application form, letting Song Yao go herself is also fine, but in the end, it's better for her to go herself, which can save a lot of trouble.

"Did these two young people start dating in high school?"

Xu Qingzhou rubbed his temples, planning to rest for a few minutes.

Last time he was still sighing that the proof process this time was very smooth, having a feeling of completion in one go, but on the 1st day of October, he was hit on the head, stumped by the estimation of the exponent sum.

Xu Qingzhou helped Song Yao register an LOL account, making it convenient for her and her little sister Ding Jiahui to play together—pecking at each other like rookies.

Cao Jingyu looked at the application form, thought for a while, and said: "It seems you really value this student, even running the application form yourself. Mm, being able to pass your test, the strength is definitely not weak, and her grades are obvious to all, this is not a problem."

Various charts and data, there are relationship charts between the net change of Li dendrite length in cracks and capacity within a fixed charge-discharge cycle, and also voltage-time relationship charts.

The sunlight shone warmly on people, not scorching at all.

Cao Jingyu, upon meeting, asked with a smile: "I heard you want to take our department's student Song Yao as a student?"

Initially, she was worried whether her prospective apprentice would be affected by her partner in her studies, but now it seems it has reversed? No, Xu Qingzhou is very amazing, and her future apprentice won't be weaker than others... This little girl is very amazing.

It's just that he kept holding her hand and pinching it.

Song Yao still didn't speak, looking at him faintly, her gaze unkind.

【When A_p={n∈A: p|n} and P={p: p≤z}, S(A, P)=π(x, z) S(A, P_2)=π_2(x, z)】

Xu Qingzhou was touched instead; Song Yao at this time didn't have the usual coldness on her face, and even the threatening gaze now was heartbreakingly beautiful.

Secretly scolding himself, Xu Qingzhou shook his head, emptying his thoughts. Song Yao was still sleeping, and he planned to wait for her to wake up before going out to buy breakfast.

Might as well stay at home and lie down.

The two had been together for a long time, and they had seen each other's sloppy appearances, so Song Yao didn't have the idol baggage like before, needing to tidy up her hair before leaving the bedroom.

"Auntie Jia, we still have things to do, let's go first."

Song Yao blinked, didn't move, seemingly considering how to punch this guy who "teased" her.

"Is this the tenant of that house of yours?"

Last night there was a night rain, today is a sunny day, golden sunlight shone in from outside the floor-to-ceiling window, spilling onto a corner of the desk.

Song Yao's class exemption application passed smoothly, no need to go to class, but she was busier than before.

"On the 8th of next month, Professor Dong Yixuan from Nandai is bringing a team over for exchange; here are the meeting materials, familiarize yourself with them."

Xu Qingzhou helped the school beauty Song tidy up her hair, gave her forehead a "pa" kiss, and said: "You sit and rest first, I'll go buy breakfast."

"Good."

But, the accumulation of knowledge is equally important.

"Li Jiaoshou."

How to say it, it's like a senior brother I met back then.

!.

According to the model prediction, the first discharge capacity can reach 2455mAh·g-1, at the same time, the reversible specific capacity at 0.1, 0.25, 0.5C is roughly 1679mAh·g-1, 1285mAh·g-1 respectively... Of course, the model can only simulate based on data, forming a guess; the specific details still need Professor Zhao and Wang Wang Shixiong Wang Wei and the others to verify themselves.

After a few minutes, the sound of footsteps came from the ear.

On this side, Xu Qingzhou felt the delicacy of the small hand, his index finger occasionally drawing a circle in the school beauty Song's palm.

Holidays, the vehicles and pedestrians on the road didn't seem so busy, everything appeared quiet and peaceful.

【This means that when n≤pz, there is: π_2(pz)=pz^2∏_{3≤p≤z}(1-2/p), there exists a constant M.】

"Quite young."

"Yes, that young man was even on the news."

"Yo~ your house was bought right, the feng shui is good, look at your son, career is successful..."

The two turned a corner and walked to the street where there was a breakfast shop; behind them, the aunties' voices were drowned in the wind.
