"One bottle of Wusu beer is enough. There will be surgery tomorrow, so you can't drink too much." Liu Zewei smiled.

"That's twenty." Su Yun said.

"..." Liu Zewei was stunned for a moment. Are there twenty bottles of death-taking Wusu? Do you really have to drink so much? Su Yun is sure to hear clearly that he only drinks one bottle?

The beer girl happily went to get the beer. Zheng Ren asked curiously: "Why is it called the Deadly Dawusu?"

"There are two reasons." Su Yun was very happy when he saw the deathly Wusu. "The main reason is that the wine is drunk quickly, and he has a split headache the next day."

"..." Zheng Ren didn't understand, what was the wine on it?

Generally speaking, the throat is soft and the stamina is very strong. After being drunk, the wine that is refreshed the next day without having to be able to be considered a good wine.

"Doctor Su is right. A friend of mine broke up and took me to drink. He usually drinks eight bottles of Wusu after drinking eight bottles of Wusu." Liu Zewei smiled bitterly.

"There are also provincial capitals?" Su Yun was surprised.

"No. It was sent to the mail by a family member of a southern Xinjiang patient, saying it was produced by the old craftsmanship, and it had nothing to do with Carlsberg's new factory."

"Old Liu, your friend, is heartbroken?" Xie Yiren noticed this.

"Uh... it's normal for the old trees to bloom new flowers." Liu Zewei originally wanted to drive, but he immediately realized that it would be better to be a good person when talking to Boss Zheng's girlfriend.

"Yiren, don't interrupt." Su Yun said: "Can that patient still contact you? I also think that the recent death-related Dawusu high-grade alcohol and miso alcohol are too much, not as good as before."

"I asked." Liu Zewei smiled and said, "Actually, there were many kinds of alcohols in the past, otherwise why would it be the next day?"

"Then you still drink it?" Zheng Ren really didn't understand what these people were thinking.

"There is no life without drinking, no friends without drinking, it is a pity to see anything without drinking, and if you don't drink, you will be abandoned by the whole world. Boss, did you notice that I'm talking about you?" Su Yun said seriously at a rare occasion.

Zheng Ren shook his head.

As he was talking, the beer girl came over with a few red bottles of Wusu.

Su Yun picked up a bottle and put it upside down on the table, "Boss, see what this is?"

The abbreviation text above should be pinyin wusu, but the wine bottle is turned into an English letter - nsnm.

"This is……"

"Kill you!" Su Yun laughed and said, "Boss, don't you want to try such an arrogant beer?"

"I don't want to." Zheng Ren directly ended the topic.

"It's such a boring life, no wonder you have no friends." Su Yun said: "Come on, drink water, let's drink beer. Fuguier, Wusu's geographical latitude is similar to Munich, and the beer tastes similar, you can drink some."

"Drink less, don't drink too much." Zheng Ren was a little nervous today.

"Boss, you are different from usual." Su Yun said contemptuously.

"Yeah." Zheng Ren also admitted, "For tomorrow's surgery, you and Fuguier must have at least one person to help you. I'm afraid there will be any problems with Dr. Mehal."

"Director Zhang is here." Su Yun made an excuse.

"I don't cooperate well enough." Zheng Ren said: "Actually, I think Fuguier will definitely not be able to go to the next day. The operation is more difficult. You should wear lead clothes to get a table."

"Boss, that's not what he said at the beginning." Su Yun said: "Old Liu is here, why are you looking for me?"

"Lao Liu was involved in the tumor, and the heart was not familiar with it." Zheng Ren pondered, his mind full of surgery on Dr. Mehal tomorrow.

In the training of the system operating room, the auxiliary operation of the experimental subject has an unpredictable impact on the operation.

Moreover, Zheng Renneng expected that the reason why Dr. Mehal wanted to be an assistant was not only Nobel Prizes, combat, etc., but more because he wanted to actually touch the transparent ceiling between the level of the giant and the peak.

There must be countless questions raised during the operation, and there are also surgery and answer questions. Zheng Ren is worried that he can't take care of him.

At this time, you must have the most assured person to help take care of him.

"Boss, you're worried about yarn." Su Yun despised.

"I'm thinking about the formula of medical physics. Can he understand what you said to Dr. Mehal tomorrow?" Zheng Ren said.

Liu Zewei was stunned for a moment.

Medical physics?!

What the hell is that?

Chang Yue didn't understand what Zheng Ren was saying at all, and it had nothing to do with her. Xie Yiren had already started barbecue with her. The meat was placed on the iron pot and made a sizzling sound, with a scent of meat everywhere.

"The law of stickiness?" Su Yun poured himself into his own drink, and was not polite. He drank a glass of Deadly Dawusu first, which seemed to be very enjoyable.

"Um."

"Boss Zheng, what is that?" Liu Zewei began to feel guilty.

He originally thought that the operation was done well, which was just a process. But he didn't expect that Boss Zheng would come up with medical physics. What exactly is this?

The deadly Wusu who was put on the bottle seemed to be wandering in front of you, killing you... Liu Zewei felt that he had been killed.

"When viscous fluid flows laminarly, the flow velocities of each layer are different. There is friction between two adjacent layers, which is called internal friction and also called viscous force. The magnitude of the force is related to the velocity gradient here, and is related to the viscosity coefficient of the fluid, and obeys Newton's law of viscousness." Zheng Ren explained professionally.

"The guidewire and catheter have to face the laminar flow of viscous fluid in the blood vessel. There are formulas to calculate. If it is an ordinary interventional surgery, it will be fine if there is no plaque. But if it is a heart surgery, it is best not to touch the coronary artery."

"..." Liu Zewei didn't understand a single word.

As a professor in the group of the Affiliated Hospital of Medical University, he ranks among the top 100 in the country, and he is also considered a well-known professor.

He never expected that one day he would explain some kind of explanation of his specialty interventional surgery and would not understand a single word.

"Old Liu, f=ηs(dv/dx)." Su Yun dipped his fingers into the deadly Wusu and wrote a formula on the table.

Chang Yue frowned when he saw it. It was too dirty. I wonder if his fingers would be put into the beer glass again, if it were...

"..." Liu Zewei was speechless. What the hell is this?

Medicine is considered a science subject, but sincerity has nothing to do with physics.

Seeing that Liu Zewei was confused, Su Yun began to explain.

"f is the viscous force, s is the contact area between the two flow layers, dv/dx is the velocity gradient in the blood vessel, and the proportional coefficient η is called the viscosity or viscosity coefficient of the fluid, and the unit is pa·s or p."

"When operating the guide wire, at least such a formula should exist in your mind to accurately create a certain connection between the guide wire and blood turbulence. The guide wire is off-limited? If you understand this formula, this situation will not happen."

"..." Liu Zewei could only be deeply amazed.
