"A bottle of Wusu beer is enough. There are still surgery tomorrow, but you can't drink too much." Liu Zewei smiled.

"That will be twenty." Su Yundao.

"..." Liu Zewei stunned, 20 bottles of life-threatening Wusu? Really want to drink so much? Su Yun decided to hear clearly that he only drank a bottle?

The beer girl is happy to get the beer, and Zheng Ren curiously asks: "Why is it called the big Wusu?"

"There are two reasons." Su Yun saw a big Usu, and he was very happy. "The first and foremost reason is that this wine is drunk and drunk, and the next day it hurts."

"..." Zheng Ren did not understand, what is good for the wine on the top.

Generally speaking, the throat is soft and the stamina is very big. After the drunk, the next day, the refreshing wine is not a good wine.

"Doctor Su is right. I fell in love with a friend and took me to drink. Usually I took eight bottles of Wusu in the amount of liquor, and the whole person was broken." Liu Zewei smiled bitterly.

"There are also provincial cities?" Su Yun is different.

"No. It is a family member of a patient from southern Xinjiang who sent it by post. It is said to be an old craft, and has nothing to do with Carlsberg's new factory."

"Old Liu, your friend, lost love?" The Xie Yi people are paying attention to this.

"Oh... the old tree is opening a new flower, it is normal." Liu Zewei originally wanted to drive, but he immediately realized that talking to Zheng’s girlfriend, it’s better to have this point.

"Ira, don't fight." Su Yundao: "Can that patient still be contacted? I also think that the recent life-threatening big ursolic alcohol and miscellaneous alcohol are too much, not as good as before."

"I asked." Liu Zewei said with a smile: "In fact, in the previous wine, there were more alcohols, or why the next day."

"Is that still drinking?" Zheng Renzhen did not understand the thoughts of these people.

"No drinking, no life, no drinking, no friends, no drinking, no fun, no food will be abandoned by the whole world. Boss, do you notice that I am talking about you?" Su Yun rarely said seriously.

Zheng Ren shook his head.

As he said, the beer girl took a few red bottles of Wusu.

Su Yun picked up a bottle and poured it on the table. "Boss, see what this is?"

The abbreviated text above should be pinyin wu, but the bottle is turned over by Su Yun, it becomes the English letter - nsn.

"this is……"

"Kill you!" Su Yun laughed and said: "The arrogant beer, the boss, you don't want to taste it?"

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

"It's a boring life, no wonder you have no friends." Su Yundao: "Come, drink water, we drink beer. Rich, ah, the geographic latitude of Wusu is similar to that of Munich, and the taste of beer is similar. You drink."

"Let's drink less, don't drink too much." Zheng Ren is slightly nervous today.

"Boss, you are not the same as usual." Su Yun said slyly.

"Yeah." Zheng Ren also admitted, "Tomorrow's surgery, you and Fuguier must have at least one person to take the handle, I am afraid Dr. Mehar has a problem."

"The director of the circular Zhang is here." Su Yun made an excuse.

"There is not enough tacit understanding." Zheng Rendao: "In fact, I think that Fuguier will definitely not go to tomorrow, surgery is more difficult, or you can wear lead clothes to match Taiwan."

"Boss, this is not the case at first." Su Yundao: "Where is the old willow, why are you looking for me?"

"Old Liu is involved in tumors, and the heart is unfamiliar." Zheng Ren is indulged, and his mind is all about surgery for Dr. Mehar tomorrow.

In the training of the system operating room, the auxiliary operation of the experimental body pair has an unpredictable effect on the operation.

Moreover, Zheng Ren can expect that Dr. Mehar is an assistant, in addition to the Nobel Prize, the battle and the like, more because he wants to actually touch the transparent ceiling between the level of the master and the peak.

There must be countless problems raised during the operation. While still having surgery, and answering questions, Zheng Ren is worried that he will not be able to take care of him.

At this time, you must be the most assured person to help look after you.

"Boss, you are worried about a wool." Su Yun swears.

"I am thinking about the formula of medical physics. You explain what Dr. Tian and Mehar said, can he understand?" Zheng Rendao.

Liu Zewei stunned.

Medical physics? !

What kind of ghost is that?

Chang Yue didn’t understand what Zheng Ren was saying, and she had nothing to do with her. The Shea people have already started to cook the meat by hand, and the meat is placed on the iron pan, giving a sizzling sound, and a meaty fragrance.

"Adhesive law?" Su Yun self-satisfaction, not welcome, first drink a cup of life-threatening Wusu, it seems to enjoy.

"Ok."

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

He originally thought that surgery should be the first step, that is, the process of only hand. But I didn't expect Zheng boss to pull out medical physics. What is this?

The bottle of the big Usu, which was put upside down, seems to be swaying in front of you, killing you... Liu Zewei feels that he has been killed When the viscous fluid laminar, the flow speed of each layer is different. There is friction between two adjacent layers, which is called internal friction and is called viscous force. The magnitude of the velocity is related to the velocity gradient at that point, related to the viscosity coefficient of the fluid, and obeys Newton's law of viscosity. Zheng Ren explained very professionally.

"The guide wire and the catheter must face the viscous fluid laminar flow in the blood vessel. There is a formula to calculate. If ordinary interventional surgery, touching the blood vessel wall, and no plaque, things can be solved. For heart surgery, it is best not to touch. Coronary."

"..." Liu Zewei did not understand a word.

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

He never thought that one day he would have some explanation for the interventional surgery of the hand, and he could not understand a word.

"Old willow, f = ηs (dv / dx)." Su Yun with his fingers dipped in the big Wusu, wrote a formula on the table.

Chang Yue’s straight frown is too dirty. I don't know if his fingers will go to the beer mug again, if...

"..." Liu Zewei is speechless, what is this special ghost?

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

Su Yun saw Liu Zewei's face stern and began to explain.

"f is the viscous force, s is the contact area between the two 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, in units of pa·s or p."

"When operating the guide wire, there must be at least one formula in the brain, which will accurately lead to a certain relationship between the guide wire and the blood turbulence. The guide wire runs off? If you understand this formula, it will not appear. This is the case."

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

He has been speechless and has been ruined.
