Chapter 1263

"One bottle of Wusu Beer is enough. There will be surgery tomorrow, but you can't drink too much." Liu zewei smiled.

"Twenty then." Su yundao.

"..." Liu zewei was stunned. Did he have twenty bottles of deadly Wusu? Do you really want to drink so much? Su Yun is sure to hear clearly that he only drinks one bottle?

The beer sister happily went to get the beer. Zheng Ren asked curiously, "why is it called lethal big Wusu?"

"There are two reasons." Su Yun was very happy when he saw that there was a deadly big Wusu. "First of all, the main reason is that this wine gets drunk quickly and has a splitting headache the next day."

"..." Zheng Ren doesn't understand. What's good to drink.

Generally speaking, it's soft in the throat, but it has great stamina. After being drunk, it's refreshing the next day. The wine that doesn't need to be penetrated is a good wine.

"Dr. Su is right. I lost my friend and took me to drink. When he drank eight bottles of Baijiu, he broke the tablets." Liu zewei said with a bitter smile.

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

"No. It was sent by a patient's family in southern Xinjiang. It said it was produced by the old craft and had nothing to do with Carlsberg's new factory."

"Lao Liu, your friend, lovelorn?" That's what the shea noticed.

"Er... It's normal for old trees to bloom new flowers." Liu zewei wanted to drive, but he immediately realized that it was better to speak to boss Zheng's girlfriend.

"Yi Ren, don't interrupt." Su Yun said: "can the patient still be contacted? I also think there are too many higher alcohols and fusels in the recent deadly big ussu, which is not as good as before."

"I asked." Liu zewei said with a smile, "in fact, there were more alcohols in the old wine. Otherwise, why did it come to the head the next day?"

"Then drink?" Zheng Renzhen doesn't understand what these people think.

"If you don't drink, you will have no life, no friends, nothing to see. If you don't drink, you will be abandoned by the whole world. Boss, have you noticed that I'm talking about you?" Su Yun rarely said it seriously.

Zheng Ren shook his head.

Just then, the beer sister came with some red bottles of Wusu.

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

The abbreviation above should be Pinyin Wusu, but the wine bottle was turned upside down by Su Yun and turned into an English letter - nsnm.

"This is..."

"Kill you!" Su Yun smiled and said, "don't you want to taste such arrogant beer, boss?"

"No." Zheng Ren ended the topic directly.

"It's a boring life. No wonder you have no friends." Su Yun said, "come on, you drink water and we drink beer. Rich and noble, the geographical latitude of ussu is similar to Munich, and the taste of beer is similar. Drink some."

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

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

"Yes." Zheng Ren also admitted, "tomorrow's operation, you and Fuguier should have at least one person to help. I'm afraid Dr. mehar has a problem."

"Director Zhang is here." Su Yun makes excuses.

"The cooperation is not tacit enough." Zheng Ren said, "in fact, I don't think rich children will go to school tomorrow. The operation is more difficult. You'd better wear lead clothes to match the stage."

"Boss, that's not what I said at first." Su Yun said, "Lao Liu is here. Why are you looking for me?"

"Lao Liu is involved in the tumor. He is not familiar with the heart." Zheng Ren pondered. His mind was full of the operation for Dr. mehar tomorrow.

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

Moreover, Zheng Ren can predict that the reason why Dr. mehar wants to be an assistant is not only because he wants to win a Nobel Prize and fight, but also because he wants to actually touch the transparent ceiling between the master level and the peak.

There must be countless questions raised during the operation. While having to operate, Zheng Ren has to answer questions. Zheng Ren is worried that he can't take care of himself.

At this time, we must have the most assured people around to help take care of it.

"Boss, you worry about a wool." Su Yun despised.

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

Liu zewei was stunned.

Medical physics?!

What the hell is that?

Chang Yue doesn't understand what Zheng Ren is talking about, and it has nothing to do with her. Xie Yi people have begun to barbecue meat by themselves. The meat is put on the iron pot, making a Zizi sound, and a smell of meat overflows.

"Law of viscosity?" Su Yun poured and drank himself. He was not polite. He drank a deadly big Wusu first. It seemed that he enjoyed it very much.

"Yes."

"Boss Zheng, what's that?" Liu zewei began to feel guilty.

He originally thought that the operation was the end, that is, the only hand familiar process. But I didn't expect boss Zheng to pull out medical physics. What is this?

That bottle of deadly big Wusu placed upside down seems to be wandering in front of you and killing you... Liu zewei feels that he has been killed.

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

"The guide wire and catheter have to face the laminar flow of viscous fluid in the blood vessel. There is a formula to calculate. If ordinary interventional surgery touches the blood vessel wall and there is no plaque, things can be solved. But for heart surgery, it's best not to touch the coronary artery."

"..." Liu zewei didn't understand a word.

As a leading professor in the Affiliated Hospital of Medical University, he can rank among the top one or two hundred in the country. He is also a well-known professor.

It never occurred to him that one day he would not understand a word about his famous intervention.

"Lao Liu, F= η S（dv/dx）。” Su Yun touched the deadly big Wusu with his fingers and wrote a formula on the table.

Chang Yue frowns. It's too dirty. I wonder if his finger will put it in the beer glass again, if

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

Medicine is a science, but it really has nothing to do with physics.

Seeing Liu zewei's face 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 scale coefficient η It is called the viscosity or viscosity coefficient of the fluid, in PA · s or P. "

"When operating the guide wire, there must be at least such a formula in your mind to accurately make a certain connection between the guide wire and blood turbulence. Guide wire deviation? If you understand this formula, this will not happen."

"..." Liu zewei could only marvel deeply.

He was speechless and dead.
