"Differential centrifugation?"

Except for the nine soldiers who were still assembling the Type 95 automatic rifle, everyone else wanted to figure out how Zhang Yang had accurately removed the parts of the Type 95 automatic rifle from a large pile of parts.

As a result, Zhang Yang calmly said what differential centrifugation method!

And it is also said that it is high school knowledge.

In the same nine years, you He Xiu?

Fan Tianlei and Gong Jian, two older people on the field, looked at each other, and they didn't know how long their high school days had passed.

I have long forgotten all the knowledge I have learned.

Some of the recruits knew about differential centrifugation, but they couldn't figure out what it had to do with the sorting of firearm parts.

Zhang Yang sighed, almost causing others to vomit blood.

"Differential centrifugation is mainly a method of separating organelles of different sizes by gradually increasing the centrifugation speed. The initial centrifugation speed is low, allowing the larger particles to settle to the bottom of the tube, while the smaller particles remain suspended in the supernatant. The precipitate is collected, the centrifugal suspension is changed to a higher centrifugation speed, the smaller particles are settled, and so on, to achieve the purpose of separating particles of different sizes. ”

Zhang Yang recited the concept of differential centrifugation like an endorsement.

At this time, the other nine soldiers ran over after completing their mission, and happened to hear Zhang Yang's words.

After He Chenguang heard it, he didn't know what to do.

Wang Yanbing and Li Erniu looked at each other even more, not knowing what Zhang Yang was talking about.

At this time, Fan Tianlei coughed and said to Zhang Yang: "Don't sell it, talk about something we can understand." ”

"Alas......"

Zhang Yang sighed again.

The others almost stumbled and fell to the ground.

You always sigh, how can you have a feeling that we have a low IQ.

Zhang Yang's sigh was actually for a reason, he remembered that not long after he won the Nobel Prize in his previous life, there were many scientists who were close to the sixtieth birthday, and mathematicians shamelessly asked him for scriptures.

The scene in front of him made him feel a little emotional, and he almost burst into tears.

"Hehe, in fact, as mentioned earlier, differential centrifugation is mainly to separate structures of different densities by gradually increasing the centrifugal speed! The density of individual organelles is not the same, so differential centrifugation can separate organelles of different densities. ”

"By the same token, although some parts of the Type 95 and Type 87 automatic rifles are similar in appearance, the forging materials used in both are metal of different densities."

"So I can separate the different parts by manual differential centrifugation!"

"It's actually the same as using a sieve to screen different objects, using the physical properties of the objects to screen, but the differential centrifugation method is more complicated."

Zhang Yang felt that the really powerful teacher did not talk about some obscure knowledge, but used his own methods to explain some unfathomable knowledge so that even sixty or seventy-year-old people could understand it.

Zhang Yang felt that he had already achieved a little bit now.

But some of those present were silent, and some were in tears.

"It sounds like it makes sense, but why can't you understand it?"

Almost everyone present felt this way!

"Ahem! Zhang Yang, your method is good, but I haven't heard of anyone using it before? ”

"How did you find out?"

Fan Tianlei asked stiffly.

"Well, I don't know why, but I found out one day." Zhang Yang didn't know how to answer, so he had to prevaricate.

He can't say that he has won three Nobel Prizes.

According to his memory, I was in the country where I was a special soldier, and no one had won the Nobel Prize at that time.

"This ......" is not the answer to this one, and Fan Tianlei has no choice but to give up.

"In that case, let's do it at this stage!"

"Zhang Yang temporarily ranked first with perfect results, everyone has no objection!"

Gong Jian probably couldn't ask anything, so he was ready to start the next round of the game.

"Nope!" The soldiers sang loudly.

As far as this first round is concerned, they were convinced by the flamboyant performance.

"In that case, the second item of the assessment below, the physical fitness assessment!"

"Physical Fitness Assessment: ......"

Just as Gong Jian was about to announce the content of the physical fitness assessment, Fan Tianlei leaned close to his ear and said a few words.

I saw Gong Jian nodding and said, "Originally, the content of the physical fitness assessment was ten kilometers of weight-bearing orientation off-road!" ”

"But just now, after my communication with Lao Fan, we agreed that a soldier's physical fitness can only be tested on his strength and endurance."

"As a soldier, you must not only have strength, but also have certain fighting skills."

"Therefore, the physical fitness assessment is modified to one-on-one fighting, and the time is limited, so there is no need for all the people involved in the assessment to have one-on-one fighting."

"Zhang Yang, in view of your excellent performance in the first round, you can choose one of the nine of them as your opponent in this round of physical fitness assessment!"

Immediately the audience was in an uproar, according to the previous way, the second round of physical fitness assessment is generally weight-bearing long-distance running, orienteering or something.

Now that it's changed to martial arts, it's a good show.

Compared to boring long-distance running with weights, one-on-one combat is much more exciting.

Zhang Yang was also a little surprised in his heart, isn't the physical fitness assessment just a test of strength?

Do you have to force me to do it?

"I choose He Chenguang! I'm going to 1v1 with him! Zhang Yang almost blurted out, so he chose He Chenguang.

For a moment, everyone present stopped breathing.

"What? Did I hear me right? ”

"He actually chose He Chenguang? Isn't that a bit self-sufficient! Look at his body, he doesn't have many muscles! ”

When Zhang Yang said his choice word by word, the entire army suddenly burst into a heated discussion.

Although most people are not cynical about Zhang Yang's choice, almost none are optimistic about Zhang Yang.

Gong Jian was also stunned for a moment, he didn't expect Zhang Yang to choose He Chenguang.

He and Fan Tianlei had already seen Zhang Yang's physical fitness, but martial arts was definitely not something that could be done by brute force alone.

Four or two dial a thousand pounds! Good martial arts skills can often do more with less.

"Zhang Yang, do you want to change someone!" Gong Jian thought about it, but still said this.

The eldest husband was full of his words, not to mention that he was in the army, Gong Jian was afraid that what he said would hurt Zhang Yang, so he thought about it again and again before saying his thoughts.

Zhang Yang shook his head.

He didn't know that He Chenguang was definitely the strongest fighting ability among the nine soldiers.

He Chenguang, who has been talented in martial arts since he was a child, has become a national youth level martial arts champion long before joining the army, and it is He Chenguang's good kung fu that has attracted Fan Tianlei's attention, hoping that he will give up martial arts and join the team of special forces.

After a long period of training in the army, He Chenguang's martial arts will only go straight to the top!

But will Zhang Yang give up?

No!

Whether it is his pride and self-confidence as a special forces god of war now, or his talent and uninhibited in his previous life.

He was not allowed to choose any other person.

The husband is born as a human being, how can he be afraid!

"There is no joke in the army, I won't change it, I understand your kindness, Chief Gong!"

Zhang Yang gave his answer with a calm face, but anyone could feel his endless fighting intent.

A real man should always be strong and fight.
