And we cleared out all the white dielectric material from inside the horn.

我们把喇叭所有 白色介电材料都清理掉了。

Or sometimes we refer to it as the dielectric constant.

有时我们将其称为电介质常数。

We call this it's dielectric property.

我们称之为介电特性。

So, by using a very thin dielectric, the distance is decreased while the plates remain separate.

因此，使用非常薄的电介质，可以减少 距离，而两个面板保持分开。

And that's why the full equation for capacitance includes a dielectric constant, K.

因此，全电容方程包含一个常数 隔离，K。

Once the steel pipe is fully welded closed, it's slowly filled with a non-conductive  oil known as liquid dielectric.

一旦钢制管道完全焊接封闭，就会慢慢填充一种称为液态电介质的非导电油。

Now if we take a dielectric and slide it in the middle, well this dielectric is just free space.

现在如果我们取一个电介质并将其滑到中间，这个电介质其实就是自由空间。

So dielectrics can help capacitors hold even more energy.

所以电介质有助于电容器存储更多 的能。

And what happens is as that field moves through the dielectric, what it does is shifts the electrons.

当电场穿过电介质时，它会移动电子。

And if I pull that dielectric out then our capacitance dropped down to 0.

而且如果我把那个电介质抽出来，那么我们的电容就会降到0。

And this something is called a dielectric – typically an insulating material like plastic or glass.

这种东西叫做绝缘体。通常，它是 它是一种绝缘材料，例如塑料和玻璃。

And so what happens when we add a dielectric in the middle, when we add an insulator in the middle?

当我们在这中间加入一个电介质，也就是加入一个绝缘体时，会发生什么？

And then in the middle we have a dielectric.

而在中间我们有一个电介质。

A dielectric is used to increase capacitance while preventing any charge from jumping from plate to plate.

绝缘体用于增加容，同时 防止任何货物从一个盘子跳到另一个盘子。

And so if you add a dielectric between these two conducting plates, what you are doing is resisting that electric field.

在两块导电板之间加入电介质，实际上是在抵抗电场。

Second, it's composed of three functional sections, a gate, a charge trap, and a channel, with dielectric barriers used to separate each section.

第二， 它由三个功能部分组成，包括一个栅极、一个电荷陷阱和一个通道，并使用介电屏障将各部分隔开。

Circulating the dielectric oil helps to keep  the temperature within the pipe consistent along the line, but can't control how that average  temperature changes over time.

循环绝缘油有助于保持管道沿线的温度一致，但无法控制平均温度随时间的变化。

And so we now see that we have a dielectric constant that is going to be higher than our constant which was 1.

我们现在看到电介质常数将会高于我们之前的常数1。

And the molecules that make up dielectrics are polar, which means one side of the molecule is slightly positive while the other side is slightly negative.

构成绝缘体的分子是极性的，这意味着 分子的一端是正的，而另一端是负的。

Today here at Crash Course Chemistry we learned about some of the properties of water that make it so special: it's polarity and it's dielectric property.

今天在《 Crash Course 化》中，我们习了水的一些特殊性质：它的极性和介电性质。
