Chapter 442

Looking at the people with different expressions in the large conference room, Zhang Fan gently squeezed the speech he had prepared for a long time into a ball! No, they didn't treat him as a dish.

Originally, Zhang Fan also wanted to make his report from shallow to deep, from narrow to wide, from specific to non-specific, and prepared many answers and explanations for the other party's questions.

For the expert group, Zhang Fan also picked several questions he had questions about. At the beginning, Zhang Fan thought that it would be good to have both ideas and thinking.

I can't use it now. If Zhang Fan's strength is poor today, he will hang in this place. Absolutely, it's a negative teaching material. How embarrassing, how embarrassing, how embarrassing. Since you don't treat me as a dish, I'll get a man Han banquet to support you.

There's no prologue, let alone welcome.

"None of the top ten scientific research institutions and hospitals in the world is an Asian country. Everyone is complacent and self breeding in a circle. Some scientific research institutions don't even understand the simplest basic principles, and there's no research. "

As soon as this was said, the following students were excited“ Inside, inside! Turn on the recording! "

The doctors who have worked for a long time despised one face, "not doing it, not has the final say."

The expert group, "angry, ha ha, the little guy has a good temper."

"Ha ha! See what he can say. If you just rely on this kind of cheekiness, you will be angry if you are angry. What can you do to me! "

Zhang Fan paused and then said, "what are the factors that determine the injury? It is the speed, the stability of the missile, the weight and type of the missile, and the characteristics of human tissue.

M193, when the impact velocity is greater than 140ms, an instantaneous cavity will be generated. " Speaking, Zhang Fan began to draw the differences of bullets entering various parts of the human body in several pictures.

"The skull can be divided into two categories. The first category is penetrating. According to the injury situation, this category can be roughly divided into four categories: blind tube injury, penetrating injury, tangent injury and rebound injury.

For blind injury, first of all, a brief physical examination of the nervous system and the whole body should be done for the wounded, including consciousness turntable, vital signs, bilateral pupils and limb activities. When dealing with local wounds, colleagues must carry out a series of emergency treatment.

For patients with severe brain edema, 20% mannitol can be rapidly injected intravenously. For patients with brain hernia, mannitol should be pushed intravenously and furosemide 40 ~ 80mg should be used at the same time. Intracranial pressure must be reduced quickly to reset brain hernia.

For the cavity effect of this injury, in the brain and dura... "

Although Zhang Fan is seldom angry and hardly conflicts with others, this only shows that Zhang Fan's high quality does not mean that he is not angry or that he has no temper.

The other party is an expert group. If it's right to say, it's a little disrespectful to people, which is tantamount to making Zhang Fan suffer a dull loss. Zhang Fan did not jump to scold or plead wrongfully.

useless! What comes in the water goes in the water, what comes in the fire goes in the fire. You give me a dull loss. I don't mean it. You think I'm a fool.

It's all about generosity and turning fighting into friendship. If you don't show your muscles, why should people be generous and turn fighting into friendship!

Zhang Fan has refined the trauma ballistics very much, almost all the essence of his own thinking and summary, and there are some very doubtful places.

Zhang Fan began to wilt, starting with human tissue and bullet energy. Very carefully and in great detail, he began to explain all kinds of data and energy formulas. When he met some places that could reflect the doctor's experience, Zhang Fan did not let go and talked about them.

An hour later, "when the battle takes place in the plateau area and the bullet passes through the human body, the energy is greatly improved, and the damage is directly doubled. For example, the depth and breadth of the wound are doubled, the wound volume is 1.7 times that of the plain area, and the clearance of necrotic tissue is 1.8 times that of the plain area.

When m193 enters the brain at high altitude,... "

Another hour passed, and Zhang Fan did not stop at all, ignoring those who raised their hands to indicate problems in the meeting“ I'm here to report, not to answer questions! " That's what the wilting Zhang Fan thinks.

"When m193 enters the chest in plateau area,..."

"When entering the lower limbs,..."

"When the battle took place in the water, m193 bullets,..."

Three hours later, the participants at the meeting were fascinated, "how can a gun talk so much? It's not nonsense. It makes sense!"

"How does this guy know so much? Experts specializing in m193? " The doctor with some work experience thought to himself.

"There are some goods in his stomach. According to his understanding of m193, he can be regarded as a vassal in this injury." The experts of the expert group chatted quietly.

"Pretty good."

Shaohua is not nervous. She can't understand it, but even if she talks nonsense on this occasion, she can speak for three hours. Now she is a little sleepy. She worried all night last night and didn't sleep well. Now she is at ease. Shaohua starts to get confused and her eyelids have begun to fight.

Jia SuYue collapsed and couldn't understand. After the initial curiosity, the rest was boundless irritability, "why is this guy so much nonsense. A broken bullet tossed and turned, from head to foot, and then another place began to say from head, repeater! "

Wang Yanan is very happy to hear it. Usually during the operation, he has time to explain it so carefully. Other things aside, Wang Yanan has a lot to gain from the anatomy of the human body. Combined with more than one year's work experience, many confused places in the past seem to be suddenly enlightened.

Three hours later, Zhang Fan finished m193. An expert of the expert group originally wanted to stand up and summarize, "this boy speaks well. I'll summarize it. He's a talent." That's what he thinks.

As a result, Zhang Fan didn't stop. Go on, today's events don't give you any reflection. You still think I Zhang Fan is a fool.

"Dragon tooth mines and directional mines belong to small explosive weapons, which are very different from high-speed automatic firearms. They all belong to range attacks. For example, dragon tooth mines are sprinkled by aircraft and can project tens of thousands of them at one time. This weapon contains 6ml of ch2no2 liquid.

Its main killing factors are high-speed small shrapnel and shock wave, and there is a certain high heat effect. Shrapnel produced by explosion is one of high-speed small shrapnel. When such weapons are densely distributed, they often cause multiple injuries to the same body.

When this weapon enters the brain

When entering the chest

When entering the abdomen,... "

Two hours later, Zhang Fan was almost angry, but he didn't stop. Men should be cruel not only to others, but also to themselves. In order not to go to the bathroom, Zhang fanleng didn't look at the mineral water on the podium.

Shao Hua, sitting in the last row, has fallen asleep on the table. With Zhang Fan's voice, she fell asleep at ease, with a slight sound.

Wang Yanan can't remember. His brain is hot. He can't help but turn on his mobile phone and listen while recording. Jia SuYue is stupid.

"I can really pull, pull, pull all morning without pause, great talent. After quarreling with Shaohua, according to this degree, Shaohua is not an opponent!"

The students have been lost and can't understand. They can also combine the decomposition diagram of human body drawn by Zhang Fan in the front, and everyone is interested in it.

As Zhang Fan talked more and drew more, and he didn't wipe it, he just piled the pictures on the picture, and the exploded picture had already become eight black lumps.

They couldn't do what Zhang Fan said. There was no picture in his eyes, but there was a picture in his heart. Looking at Zhang Fan, he continued to draw on the black Tuotuo, "here is the blood vessel, here is the nerve, here is the dura mater."

"God! This is suffering! " The energetic students have been dazzled by Zhang Fan. The female and male students look at several black lumps on the blackboard, "is this the brain? This is the place of the brain? "

Doctors who have worked for several years can barely listen, but doctors who do not engage in extramental activities cannot understand Zhang Fan's explanation of head injury, and those who do not engage in extrathoracic activities cannot understand Zhang Fan's explanation of extrathoracic activities.

"This?" An expert looked at another expert and said that Zhang Fan didn't speak well. It was against his conscience to say that Zhang Fan spoke well, but there were eight black lumps on the blackboard. He couldn't even take notes. Can it be counted!

The expert who has been to tea vegetable has a blue face. He is the deputy leader of the expert group and is responsible for many things, especially academic things.

Zhang Fan spoke very well today. There are many things that can be discussed. If Zhang Fan takes these things out to discuss with everyone, ask questions and answer them, even if it can't solve the problem.

But it can also be regarded as throwing a brick to attract jade, so that we can understand the problems more clearly. But, this guy is intentional, directly destroyed a wonderful report to“ There is no scholar's demeanor. " He gnashed his teeth and said to the experts around him.

At this time, the experts also saw that Zhang Fan was intentional“ Young and vigorous! However, the level is still good. "

"Among the ancestral disciples, he is the most domineering one. It is estimated that this character was kicked to the frontier by old Lu!"

"Who said no, it's too overbearing!" This is strength, this is muscle, no muscle, no strength. Today Zhang Fan is a monkey. If he has strength and muscle, the other party can be generous. Although we all know that Zhang Fan was intentional.

However, it's hard for experts to stand up and stop now. Zhang Fan has something to say and his level is very high. He's not talking nonsense. He's talking very much. However, it's not his business to understand or not understand.

Ha ha, Zhang Fan's heart is as cool as drinking iced Jianlibao after dog days or a hangover. Although his mouth is dry and his throat is on fire, he is very cool, "sister, it's still good for tea vegetable city hospital!" This is the real idea in Zhang Fan's heart.

Go on, Zhang Fan fought hard. Perseverance is one of his few advantages, and it is also the greatest advantage. Finished talking about the lower limb injury of small explosives.

Zhang Fan didn't even pause and went straight back to his head. Continue from the head: "the fuel air explosive bomb, that is, the so-called oil and gas bomb, is a new weapon that began to be used in the 1970s. It feeds the filler with liquid fuel and injects the fuel over the target when it is used.

Numerous suspended particles with a diameter of about a fraction of a millimeter are formed. When they are mixed with oxygen in the air to a certain concentration, explosive clouds are formed. After initiation, a strong shock wave is generated with an energy of about 4900 ~ 6900kpa.

It can kill people and destroy fortification targets in a large area. At present, it is considered to be a typical surface killing weapon

This is the tissue curve of overpressure damage caused by this weapon. During this energy node, the energy damage caused by the tissue structure of the human body can produce typical internal laceration... "

Then you can see the graph. Eight lumps are connected together. The two white writing boards almost made Zhang Fan paint the blackboard. At this time, not only the expert group, but also the doctors who have worked for several years know that this guy is intentional.

"I like having a temper and personality! Hey, hey! " The two doctors whispered with a bad smile.

"Look at the big guy in front of us at three o'clock. His face has been changed with anger. Ha ha, I cleaned up like my grandson yesterday. Ha ha! "

Eight hours later, "I knew I wouldn't go to the bathroom. I ate a little in the morning. Now my stomach is glued together. Where did this guy come from? He's so awesome. Isn't he hungry? Can't you hold your urine? " Students and students are chatting!

Shaohua woke up. She looked at Wang Yanan and Jia SuYue vaguely. The two girls couldn't carry it anymore and fell asleep on the table“ God, little stone is still talking. What time is it? "

"For microwave weapons, burning weapons and all kinds of lean oil weapons, if you are interested, you can contact me. That's all for today. " It's not that Zhang fan can't speak, it's that he's holding his urine.

He didn't say anything to ask for advice. He put down his pen and quickly left the conference room.

"Where is the bathroom?" The Secretary of the general affairs office at the door has wilted. TM's can pull too much. It's been pulling all day. God man!

"Ah, the bathroom. Oh, the bathroom is at the end of the corridor." He was almost out of his mind.

"I have to ask his teacher. I have to ask old Lu. Is this the attitude towards his peers?" The oldest expert was really angry. Pointing to the two black writing boards, the old man was already shaking with anger.

"It's my fault. I didn't make it clear to him. I guess he's a little angry." The expert who had been to tea said to the old professor.

"Even if you don't make it clear, you can't do this! Look, what did you hear from beginning to end? What do you understand? " Although the old man no longer holds any position, his academic status is still.

"It's my thoughtlessness!" The expert who has been to tea is also gnashing his teeth. He didn't expect that this guy has such a temper.

"Do you understand?" A senior doctor asked another senior doctor.

"It's OK in the front, but I can't hear it in the back. He speaks too fast and doesn't understand it without combining the decomposition diagram!"

"Me too! Although I don't understand, I know he's awesome! "

"Yes, it's awesome. Let's go. We can't give directions. Hurry to eat. He'll talk for a while. It's estimated that there will be a few hypoglycemic and hungry people in the venue! "

Zhang Fan happily drained the water, washed his hands and went out. The people in the meeting went out and left again and again. The students looked at the cow man curiously. Originally, several female students wanted to come up to find Zhang Fan for signature. But looking at the faces of several professors Tieqing, he didn't dare to come forward.

"You..." the experts who have been to tea can't speak. Looking at Zhang Fan, his mouth opened for a long time, and finally said, "greet old Lu for me!" Then he wiped Zhang Fan and left.

"Zhang Fan, Zhang Fan. How's it going, how's it going? " Shaohua anxiously waited for the crowd to go away from the back door. She hurried to come.

"Good! Hurry, give me saliva! " Zhang Fan's voice is hoarse!
