Su Xiaoting couldn't help asking: "Why don't you use capacitive paper, or plastic?" ”

The middle-aged man with some prominent cheekbones, his eyes behind the lenses were a little stunned, "We have tried plastic, the paper is so thin, it can also be used as an insulating material?" ”

Having said that, Su Xiaoting's words were like a person who was blinded by the dark night, and suddenly saw a little spark, which ignited a glimmer of hope in Tian Suo's heart.

"Have you seen it there? The capacitors used over there are said to be mainly gases and metamaterials, are you talking about microcapacitors or 'ancient' capacitors? ”

Director Tian threw out a large series of questions as if he had a series of cannons, his eyes were completely focused on Su Xiaoting, and there was anxiety, hope and doubt in his eyes. The surrounding researchers also turned around, suppressed their surprise and surprise, and looked at Su Xiaoting blatantly.

"Uh...... I saw it a while ago and this is supposed to be a primitive capacitor. However, although the cost of this insulator is low, it is not as stable as that of later ones. But it should be enough for small circuits. ”

Su Xiaoting sorted out the information in the depths of her memory, and carefully said word by word.

If memory serves, paper dielectric capacitors are one of the oldest and oldest varieties of organic dielectric capacitors. Low-frequency circuits and DC circuits with low requirements can generally be selected.

And this material seems to be more suitable for Mu Ling's craftsmanship now.

"Really? It's true?! The corners of Tian Suo's smiling mouth were vaguely curved.

Su Xiaoting hurriedly added: "But this kind of capacitive paper should not be ordinary paper, and I don't know the specific production process!" ”

“…… Well, we really haven't thought about this idea, you just said that plastic can also be? Why is the experimental data on our use of plastics so bad? ”

“…… Could it be that there is a problem with the way the wire is wound? Or is it something to do with the plastic? ”

"Winding? How to wrap around? ”

"Okay, don't worry," a voice saved Su Xiaoting, "An Ting, now we really need this knowledge, you... Would you like to help us? ”

With a pair of sincere eyes, there was no coercion from the superiors, Su Xiaoting believed that Ji Yuning would really not force her, just as he had always given his subordinates full trust.

Not to mention that Su Xiaoting has never made a distinction between a country of abandonment and a boundless land, even if she is really a citizen of a partner country, who can she damage if she turns out outdated technology that has been eliminated into the dust of history?

On the contrary, the usefulness of her outdated knowledge is due to the ambiguity of the United States' technological precipice, which cannot be imitated.

Su Xiaoting saw their intentions, Mu Ling wanted to use Jingwei's determination to fill the scientific and technological gap in front of them, such a tragic and heroic feat was no less than Prometheus's feat of stealing the fire, which moved her and made her want to contribute as well.

"I'll do my best, as long as I know!"

Ji Yuning's eyes were on Su Xiaoting, and Su Xiaoting read praise and gratitude from it.

"Good! Then you and one of them will stay and answer the questions of Shimodasho! ”

"Tian Suo, they stayed to cooperate with you today, if you need it, you can let one of them tell me, and I will come back in a few weeks." After Ji Yuning finished speaking, he and Ah Tao took the lead in leaving.

As time passed, seeing the gaze of the people present on the mountains made her feel like she was promoted to a professor of archaeology, or to become the inheritor of an intangible cultural heritage.

If the United States and the Boundless Land are compared to two planets with different civilizations in the interstellar world, Su Xiaoting may barely be counted as a small ship and ferry between the two civilizations, because people in the lower civilizations cannot understand the difficult technology of the higher civilizations at all.

However, Su Xiaoting also guessed that if another apocalyptic war broke out, the civilization level of the United States would also collapse overnight.

After a morning of discussion, although capacitive paper is still just a concept, Su Xiaoting found the reason for the failure of the plastic medium.

"There are many kinds of plastics, and it seems that polyester works better." Su Xiaoting remembers that PP material is also good, but she is not sure if there is such material now.

"Moreover, this kind of spacer method will lead to large volume and low capacity." Su Xiaoting looked at the previous device and gestured:

"You can find ultra-thin polyester plastic films, and then use these metal foils as electrodes that overlap with the plastic film and roll them together."

"Winding?" Taso's eyes sparkled, he had been standing before, and now he could only vent his excitement with gestures.

If Su Xiaoting was just a straw in his eyes just now, now it has become a driftwood. God knows, in the past, they could only guide R&D through basic physics textbooks. He couldn't bear to walk back and forth along the long table twice.

"That's right! Winding...... How did we not think of this? This is perfectly feasible in theory. ”

A researcher replied excitedly: "Yes, yes, I used to only think about expanding the electrode area, so I made the surface pitted, very uneven. If it were really possible, wouldn't it be possible to expand the capacity by 5 or 6 times compared to before? ”

One of them on the side woke up from the sleepwalking state, and finally understood a sentence, and he didn't know how to do it, so he leaned up and asked:

"Xiaoting, how do you know so much?"

Everyone's eyes immediately converged on one place, and if you want to say that no one trusts it, and those who do basic research on devices in a specialized field may not know about these.

"Ah, oh~ I have a friend who used to study device development, and I happened to hear him say it."

"Xiaoting, you are too smart, it seems that the work of remembering things will be handed over to you in the future~" One of them praised, how can his own apprentice be so smart!

Well, Su Xiaoting felt that this was really a beautiful misunderstanding, in fact, this was just a small physical improvement, she just helped them think of this method in advance, and the specific implementation was only on paper.

However, Tian Suo obviously didn't think so, and it was not until noon that one of them politely refused Tian Suo's request to keep food, and was pulled aside by Tian Suo and instructed for a while before letting the two go.

"Xiaoting, it's important to improve your strength, besides, you're not a professional researcher, it's enough to provide them with some references!"

Su Xiaoting nodded obediently, "Or do you know me, by the way, is the eldest lady coming back soon?" ”

One of them rode on the horse, nodded happily and said, "Yes, you are about to hit level 4, and you have to step up your practice." You said, Miss, she was supposed to come back, but it was about to be the annual sacrifice ceremony, and she must have to prepare for the ceremony at the temple, so she won't be back this week. ”

"So? Sacrificial ceremonies? Not everyone can participate, right? ”

"Hehe, of course not, the sacrificial ceremony, only the city lord and county-level generals can participate, and they will represent all the people of Mu Ling to carry out the annual sacrifice and worship to the goddess."

One of them raised his head arrogantly: "Of course, I will definitely accompany the boss, that scene is really ......, alas?" Xiaoting, maybe you can go with you this time! ”

"And you're a girl, although the sacrificial ceremony is a bit boring, but the scenery over there, I promise you will like it. And every year after participating in the festival, the boss will take us to the forest over there for autumn hunting, which is absolutely exciting. ”
