In fact, Zheng Ying was not only not wasted by her own father.

And during this time, I also gained great inspiration.

Especially later in terms of scientific research.

Soon after Teacher Wang came, Zheng Ying, who often went out to pick up rags, often went out to pick up rags, and they were in tatters at home, and they often went in and out of some weirdos.

Some were old friends of my father's time.

Some are some powerful people who come to ask for help.

As a child, there are many things that you don't need to know too clearly.

People of my father's generation always know some strange guys from all directions.

That day, a tall and thin handsome uncle came.

I came here, and there is a very reasonable way to say it.

"Good son, didn't my father often go out to work in the past!

So, this uncle is a co-worker I used to work with.

He is now a petty official in that factory, and he has a lot of problems that he can't figure out, so he comes to beg you again.

You see, how good your dad and I are. ”

Tan Xiaoping made up this lie in a few words.

"Again? Has this uncle been here before? Zheng Ying frowned.

The father nodded again and again: "Of course, you were in school at that time, and you were not at home, so you didn't see this uncle when he came!" ”

Zheng Ying nodded and said silently: "Alas, if my father is not sick now, it would be good if he could continue to work, maybe you would be the official now." ”

"Hehe, yes, yes.

Okay, you go cook, and I'll talk to your uncle and see what problems he's in. ”

Tan Xiaoping pretended to open Zheng Ying, which really aroused the curiosity of children.

In the same way, it is also to test him whether it is the material or not, and imperceptibly test it.

The question asked by the handsome uncle was extremely boring, and he actually said, "Big brother, do you remember the old silver powder factory?"

Now the field has been changed, and the rocket paint is recreated. ”

Uncle Shuai opened his mouth, and when Tan Xiaoping heard that something was wrong, he was so angry that he almost didn't squirt out a mouthful of water.

"Rocket paint?

We're silver powder makers, so how did we change our paintings?

It's rocket fuel, right? ”

This handsome uncle was immediately stunned, and immediately changed his words:

"Uh...... Yes, yes, yes, it's rocket fuel, you look at my stinky mouth, sometimes when I see you, I still stammer, I can't say anything, hehehe. ”

This guy is one of Tan Xiaoping's subordinates.

The boss of the iron prison base of the third base still has a certain majesty in front of his subordinates, even if he is dressed as a peasant, the relationship between superiors and subordinates still exists.

However, Zheng Ying is not clear about all these arrangements.

Although it is said that he went to the yard to fetch water, prepared to cook, and then took the pot and returned to the honeycomb coal stove at the door.

But their conversation was so curious that Zheng Ying heard it all.

"There was a problem with the rocket launch, and the satellites we brought with us ......

It is...... That is, after the rocket flies up with the satellite, it doesn't take long for the satellite to lose its signal!

But this is not a problem with our rockets, shouldn't it be a problem with satellites?

It's even strange to our factory! ”

The handsome uncle spoke, complaining with a lot of emotion.

But he didn't dare to scream, but only whispered softly, as if he was a resentful woman who had been wronged.

Zheng Ying immediately pricked up her ears and thought to herself: Rocket?

It turned out that my father used to ...... It's to make rocket launch fuel!

No, how can silver powder be rocket launch fuel?

Damn it...... I can't hear clearly, it's my own confusion.

That's right, as the uncle said just now, their factory has changed its business model and started to manufacture rocket launch fuel.

But that's also a little wrong!

Making rocket launch fuel, and not designing rockets, even if something goes wrong, you can't make trouble with their fuel at all, you should find the rocket design department, right?

A series of ideas, spinning back and forth in his own little brain.

Although it has nothing to do with me, I always feel that since I am a friend of my father, I always want to contribute.

He even felt that he could figure it out.

Soon, this handsome uncle dodged the problem.

"Big brother, of course it's not our problem, is it?

As a result, those who are engaged in scientific research also said that it is not our problem.

The problem is with the satellites, and guess what?

In the outer space of our earth, there is a layer of ultra-high-energy ionizing radiation particles!

What kind of radiation belt is said to have been discovered by a foreign scientist.

This radiation belt is roughly divided into several layers, and the one that is slightly closer to our earth is a few trillion volts of ionized protons, several trillions of dollars!

Big brother, damage a few electronic components, that's not a matter of minutes?

Fortunately, it's a satellite, not a manned spacecraft, if it's a manned spacecraft, that person can't be scrapped?

There is another layer on the outside, and the range of that layer is even larger, and it is also several trillion volts, as if it is charged particles......

Oh, no, no, it's charged electrons......

Tsk, I forgot, we're not scientists, that's what it meant anyway.

Anyway, the first layer is protons, and the second layer is electrons, and these two things are very high-voltage and strong-current. Bigger space and a 3rd floor! I wonder there's a 4th floor! ”

Tan Xiaoping was a little impatient when he listened, and glanced at him and gestured outside.

Then he coughed and said, "Ahem...... Didn't you come to me to ask questions? You tell me this, what is your problem? ”

"Oh, big brother, I'm sorry, I'm sorry, you didn't say I almost forgot, I just wanted to ask you, how can we defend against such a powerful radiation layer?"

Uncle Shuai finally pointed to the question, and this question is to test his IQ.

Tan Xiaoping didn't say anything, Zheng Ying, who was cooking outside the house at this time.

I immediately confirmed in my mind: no, it was ionizing radiation, and in addition to this, there was electromagnetic radiation.

But this layer of ionizing radiation seems to be more powerful if you want to prevent or protect it.

There are only three standard answers.

Either don't approach it, and if you do, try to shorten the approach time.

Either the protective layer is thickened, and the largest atomic number of the metal without radiation should be ...... Lead.

From this non-ferrous metal, a protective layer should be made against electromagnetic radiation.

As for ionizing radiation, inside and outside the layer of "lead", a shell made of super-insulator material must be added.

Tan Xiaoping smiled: "How simple is this!" Fill it with lead!

Wouldn't it protect you from radiation if you poured enough lead?

It can not only protect electronic components from damage, but also make space suits with money, so that astronauts can fly out without these radiation. ”

Uncle Shuai clapped his hands again and again.

"yes, why are these scientists so stupid? Why didn't they think of it?

Hahaha, sure enough, it's still my eldest brother who is good at me!

This time, I was going to ask you this question, and now they are all in a hurry, like ants on a hot pot!

I don't know what to do anymore.

If I tell them something, I'll be rewarded with a sum of money. ”。

The two were talking and laughing, and Zheng Ying walked in: "Uncle and Dad, don't you think it's too child's play when you two talk about this issue?"

That's a scientist, who has dedicated his life's work, how can this question not be imagined? ”
