"One bottle of Usu beer is enough, and 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, did you really want to drink so much of the deadly Great Wusu? Su Yun was sure to hear clearly that he said that he would only drink one bottle?

The beer girl happily went to get the beer, and Zheng Ren asked curiously, "Why is it called the deadly Da Wusu?"

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

"......" Zheng Ren didn't understand, what was there to drink about the wine on it.

Generally speaking, the wine is soft in the throat, but the stamina is great, and the wine that is refreshed the next day after getting drunk is considered a good wine.

"Dr. Su is right, a friend of mine fell out of love and dragged me to drink. Usually the amount of one pound of liquor, after drinking eight bottles of Wusu, the whole person is broken. Liu Zewei smiled bitterly.

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

"Nope. It was sent to the mail by a family member of a patient in southern Xinjiang, saying that it was produced by old craftsmanship and had nothing to do with Carlsberg's new factory. ”

"Old Liu, your friend, broken love?" Shay paid attention to this.

"Uh...... It is also normal for old trees to bloom new flowers. Liu Zewei originally wanted to drive, but he immediately realized that it was better to talk to Boss Zheng's girlfriend.

"Yiren, don't interrupt. Su Yun said: "Can that patient still be contacted?" I also think that the recent fatal Dawusu high-grade alcohols and fusels are too much, and they are not as good as before. ”

"I asked. Liu Zewei smiled: "Actually, there were more alcohols in the previous wine, otherwise why would it be the next day." ”

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

"If you don't drink, you don't have life, if you don't drink, you don't have friends, if you don't drink, you will be saddened by everything, and if you don't drink, you will be abandoned by the whole world. Boss, did you notice that I was talking about you?" Su Yun said with a rare seriousness.

Zheng Ren shook his head.

As she 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, look at what this is?"

The abbreviated text on it should be pinyin wusu, but the wine bottle was turned upside down by Su Yun, and it became the English letter - nsnm.

"It's ......"

"Kill you!" Su Yun laughed and said, "Don't you want to taste such an arrogant beer, boss?"

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

"It's a boring life, no wonder you don't have friends. Su Yun said: "Come, you drink water, we drink beer." Fuguier, the geographical latitude of Wusu is about the same as Munich, and the taste of beer is similar, you can drink some. ”

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

"Boss, you're different from usual. Su Yun said disdainfully.

"Hmm. Zheng Ren also admitted, "Tomorrow's operation, you and Fuguier must have at least one person to help, I'm afraid that Dr. Mehal has a problem." ”

"Director Zhang is here. Su Yun made excuses.

"The cooperation is not tacit enough. Zheng Ren said: "Actually, I think Fuguier will definitely not be able to go up tomorrow, the operation is more difficult, so you should wear a lead suit to go to 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 tumors, and he is not familiar with the side of the heart. Jung Ren groaned, his mind full of the operation on Dr. Mehal tomorrow.

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

And Zheng Ren could predict that the reason why Dr. Mehal wanted to be an assistant, in addition to things like Nobel Prizes and battles, was more because he wanted to really touch the transparent ceiling between the level and the peak of the master.

There must have been countless questions raised during the operation, and while the operation was still required, there were also questions to be answered, and Zheng Ren was worried that he would not be able to take care of himself.

At this time, you must have the most reassuring person by your side to help take care of it.

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

"I'm thinking about the formulas of medical physics. What you said tomorrow to Dr. Mehal, can he understand?" said Jung.

Liu Zewei was stunned for a moment.

Medical physics?!

What the hell is that?

Chang Yue didn't understand what Zheng Ren was talking about at all, and it had nothing to do with her. The Shay people have already begun to barbecue the meat themselves, and the meat is placed on the iron pot, making a sizzling sound, and the smell of meat overflows.

"The law of stickiness?" Su Yun poured himself a drink, and he was not polite, and drank a cup of the deadly Dawusu first, which seemed to be extremely enjoyable.

"Hmm. ”

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

He originally thought that the operation would be done at the head, which was a familiar process. But I didn't expect Boss Zheng to pull out medical physics, what the hell is this?

The bottle of the deadly Great Usu that was placed upside down seems to be dangling right in front of you, killing you...... Yanagi felt like he had been killed.

"In the case of laminar flow of viscous fluids, the velocity of each layer is different. There is friction between two adjacent layers, which is called internal friction or viscous force. The magnitude of the force is related to the velocity gradient at that point, and is related to the viscous coefficient of the fluid, obeying Newton's law of viscosity. Zheng Ren explained very professionally.

"The guidewire and catheter have to face the laminar flow of viscous fluid in the blood vessels, and there is a formula to calculate. If it is an ordinary interventional operation, touching the blood vessel wall, and there is no plaque, the matter is easy to solve. However, for heart surgery, it is best not to touch the coronary artery. ”

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

As a professor in the group of the Affiliated Hospital of Medical University, his level can be ranked in the top one or two hundred in the country, and he can be regarded as a well-known professor.

He never imagined that one day he would not understand a word of an explanation of the interventional surgery he was good at.

"Lao Liu, F=ηS(dv/dx). Su Yun dipped his finger in the deadly Da Wusu and wrote a formula on the table.

Chang Yue frowned when he saw it, it was too dirty. I wonder if his fingers will be put in the beer glass again, if it is......

"......" Liu Zewei was speechless, what the hell is this?

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

Su Yun saw that Liu Zewei looked confused, so he began to explain.

"F is the viscous force, S is the contact area between the two tropospheres, dv/dx is the velocity gradient in the blood vessels, and the scale coefficient is called the viscosity or viscosity coefficient of the fluid η Pa·s or P. ”

"When operating the guidewire, there must be at least such a formula in the mind to accurately make some kind of connection between the guidewire and the blood turbulence. If you understand this formula, this will not happen. ”

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

He was speechless one after another, and he had been made to death.
