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

我们把喇叭内所有 白色介电材料都清理掉了。

We call this it's dielectric property.

我们称之介电特性。

So dielectrics can help capacitors hold even more energy.

所以电介质有助于电容器存储更多 的能量。

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。

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 它一种绝缘材料，料和玻璃。

That day, when they were discussing whether the diesel oil is dielectric or not, the phone rang.

那天，他们正在讨论柴油电介质时，电话响了。

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。

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

一旦钢管完全焊接封闭，它就会慢慢充满一种称液体电介质的非导电油。

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

绝缘体用于增加容量，同时 防止任何货物从一个盘子跳到另一个盘子。

And that’s why the full equation for capacitance includes a dielectric constant, K. So dielectrics can help capacitors hold even more energy.

这就什么完整的电容方程包括介电常数 K。因此电介质可以帮助电容器保持更多的能量。

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.

循环介电油有助于保持管道内的温度沿线一致，但无法控制平均温度随时间的变化。

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，在化学速成班，我们了解了水的一些特殊特性：极性和介电特性。

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.

构成绝缘体的分子极性的，这意味着 分子的一端正的，而另一端负的。

At each end of the  transmission line is a plant filled with pumps and tanks to pressurize - and often to  circulate - the dielectric oil in the pipe.

输电线路的每一端都有一个装有泵和储罐的设备，用于对管道中的介电油加压并经常进行循环。

Over hundreds or thousands of cycles of TMB, the paper insulation around each conductor  can begin to soften or tear, eventually leading to a dielectric breakdown (in other words, arcs and short circuits).

经过数百或数千次 TMB 循环，每个导体周围的纸绝缘体可能会开始软化或撕裂，最终导致介电击穿（换句话说，电弧和短路）。

They climbed back into the dish with brooms and scrubbing brushes and carefully swept it clean of what they referred to in a later paper as white dielectric material, or what is known more commonly as bird shit.

他们拿起扫帚和抹布再次爬进抛物面天线，小心翼翼地把他们后来在一篇论文中称之白色电介质的、用更通常的说法鸟粪的东西扫得干干净净。
