Chapter 123 On the role of cats in academic research

Lin Xiao hugged the cat and went upstairs with the little girl. The little girl lived on the seventh floor, which was also the top floor. Yanbeiyuan is a short house, not a high-rise building.

So when Lin Xiao arrived at his floor, he separated from the little girl. He opened the door and returned to the house.

Afterwards, Lin Xiao put the cat directly on the ground. After entering the house, the cat seemed no stranger at all. It immediately began to patrol its new territory and walked around the house.

Lin Xiao looked at it and shook his head helplessly, what's the matter?

You went out for a trip and picked up a little guy when you came back?

Sometimes he also feels that this world is really magical, how come so many different creatures appear on the earth, and why do humans have the concept of cuteness and beauty of a certain creature.

Just like him, he had to admit that this repair cat was a bit cute.

"But why do you, this guy, wander around my house as a matter of course?"

Lin Xiao stepped forward, grabbed its two front paws, picked it up, and sat on the sofa next to it.

Rubbing its head, Lin Xiao said to it: "I just see you as pitiful and will only raise you for a few days. After you find your previous owner, you have to go back."

Thinking of this, he immediately took out his mobile phone, then found the original contact information of Teacher Liu, and asked him to help find if anyone in Yanbei Garden had lost a cat.

He then remembered the little girl who said this cat was a ragdoll cat, so he checked online and was surprised to find that the average price of such a cat was tens of thousands.

"This must have an owner, right?"

He couldn't help but think in his mind, if such an expensive cat was lost, wouldn't its owner have to die in a hurry?

Then we can only hope that its owner can be found later.

However, now that he has to be raised for a few more days, do I need to buy him some food?

Just eat the ham sausage once, but eating too much is not good.

In addition, it seems that I need to take it to the pet hospital for a checkup, and then give it a bath or something. Looking at this cat, the hair on its body is either knotted or stuck in a lump.

Thinking of this, Lin Xiao felt helpless again, it was really a bit troublesome.

"Forget it, I've taken care of it, just bear with it for a few days and send it back after finding the owner."

After making up her mind, Lin Xiao picked up the repair cat again, left the house, and took it to the nearest pet hospital.

However, when registering at the pet hospital, a pet's name was required. Lin Xiao thought about it, and then casually named it "Mimi" to make it easier to remember.

After all, cats all over China are called Mimi.

After some examination, cat moss was found on the cat's body. Cats that stray outside are prone to fungal infections. However, the doctor at the pet hospital said that the problem was not serious, and they simply treated it and then prescribed some more. The medicine will be fine.

Then it was time to take a bath. This cat obviously didn't like taking a bath and meowed when he was being washed. But the amazing thing was that it didn't toss around and just meowed. It looked pitiful and cute.

However, before taking a bath, although the cat looked beautiful, it was still a bit sloppy. However, after some grooming, it showed a different brilliance, which surprised Lin Xiaodu.

"So this is your true face in Lushan?"

Stroking 'Mimi's' head, Lin Xiao couldn't help but sigh.

Looking at the soft fur and the perfect color on the face, Lin Xiao couldn't help but get closer and took a sip on it. The smell of the shower gel made him couldn't help but say: "It smells so good." !”

At this time, the clerk from the nearby pet hospital came over: "Here is the cat food you want, as well as a cat food bowl, two bowls, one with cat food, one with water, and here are the cat litter and cat litter box , here’s your cat bag.”

"Oh, okay thanks."

Seeing the pile of things, Lin Xiao responded.

"Including the cost of treatment and bathing and care just now, the total is 1563.5 yuan. How did you pay? We also have members here. Recharge 2000 and get 200. Now we are doing an event. If you recharge, we can give you a cat scratching post and three more Nutrient paste.”

Lin Xiao couldn't help but be stunned when he heard this fee.

Damn it, so expensive?

The last time I spent four figures, I bought a computer and a mobile phone, but now I spent more than a thousand just to prepare this cat?

But seeing the smile on the face of this veterinarian lady, he had no choice but to take out his mobile phone and pay. Of course, he did not spend 2,000 to recharge the membership. He didn't know if the cat would be able to find its owner in the future. If you can’t use it after two thousand, isn’t that a loss?

So just like that, he put Mimi into the cat bag, and then returned home with a lot of things.

"Huh~ I'm finally home."

After arriving home, Lin Xiao let the cat out, put the cat's food bowl on it, poured some cat food and water, and called the cat over.

When Mimi saw that there was something to eat and drink, she quickly got into it, and it looked like the food was delicious.

Lin Xiao watched it eat, touched its body, and said at the same time: "When your master comes to find you, you have to ask him to give me more than a thousand yuan. If he doesn't give it, I will I won’t pay you back.”

He swore that it was just about the money, not the cat.

In order to show that what he said was true, he stood up directly, walked into his bedroom, and sat next to the desk.

Then he turned on the computer, read papers related to their topic, and focused all his attention from the cat to the paper in front of him.

"Well...the initial deformation must be a small displacement relative to equilibrium, in this case a prestressed uniform expansion of the reference configuration, or, the nonlinear term must be a non-resonant or zero-energy condition..."

"If considered in an incompressible elastic dynamical system, either of these two assumptions may cause the solution to collapse in a finite time."

As Lin Xiao's thoughts progressed, he gradually entered a state of immersion.

The ability brought by the system still easily allowed him to concentrate all his energy.

However, while carefully studying these papers, Lin Xiao encountered some problems.

"The zero energy condition makes the cancellation of all nonlinear wave interactions along the characteristic cone first order, if I just eliminate the nonlinear wave interactions between individual wave families..."

Seems feasible?

Thinking of this, Lin Xiao took out a pen and listed several calculation formulas on the scratch paper.

Although after the second group meeting, Lin Xiao found that he could not provide any usefulness, but after so many days of special tutoring, he already understood what their topic was researching, so he also included relevant knowledge. Already understood.

In other words, he is now able to provide certain assistance in the field of physics for the research of the subject, instead of just being limited to mathematics like last week.

In this way, he continued. I don't know how long it took, but he suddenly encountered a problem.

"How do I decompose the elastic wave into longitudinal and transverse components now? This seems to involve a non-local Helmholtz boundary value problem... This is a bit troublesome."

Seeing the problems he was encountering now, Lin Xiao couldn't help but frown and think about it.

But at this moment, he suddenly found that the cat ran over without knowing when, and actually jumped on the desktop and ran to the laptop.

Immediately, Lin Xiao came back from his immersion. When he saw this little guy, he said in a dumbfounded way: "What do you want to do?"

Mimi let out a "meow" and stood on the keyboard of his laptop again. For a moment, the screen started flipping randomly just because she pressed the keyboard.

Lin Xiao was shocked when he saw that the paper he had just read was gone, and some new web pages appeared on it, and he quickly hugged Mimi.

"You repair cat, why are you causing trouble?"

He patted the guy's head lightly, then turned to look at the computer, about to clean up these accidentally opened web pages.

But at this moment, he was stunned when he saw what was displayed on the web page.

"Nonresonance and global existence of prestressed nonlinear elastic waves?"

"Abstract...only resonant interactions along the characteristic cone affect the calculation, so an approximate local estimate can be used?"

"Approximate local estimates..."

Lin Xiao's eyes suddenly lit up, and he quickly started trying on the scratch paper. Mimi, who was next to him, seemed to know that he was doing something important. She lay obediently next to the table, her two big crystal blue eyes motionless. Look at Lin Xiao.

Lin Xiao ignored Mimi and looked at the formula he came up with.

"The zero energy condition places a limit on the growth of the stored energy function of the expansion strain extreme, so the value obtained is a bit too small... So now it is necessary to correct the previous zero energy condition?"

Lin Xiao had a sudden feeling. If he hadn't solved this problem, their projects would probably have gone in the wrong direction. It wasn't until they hit the south wall that they remembered to go back and check.

Moreover, this question does not only mean a problem for their project, it is very important even for the research team that studies related content.

Immediately, he couldn't help but look at Mimi, who was lying quietly next to him. If the repair cat hadn't helped him see this paper by pressing it randomly, he probably wouldn't have gotten such an important conclusion.

This is a little savior!

Immediately, he leaned forward, buried his nose into Mimi's little head, and took a deep breath.

“It smells so good!”
