Next, a three-atom-thick layer of molybdenum disulfide converts that AC signal into usable DC electricity.

接下来，三原子厚的二硫化钼层交信号转换成可用的直。

The inverters then convert it from dc direct current to ac alternating current.

然后变从直转换为交。

It's just, it's just a direct current, is exactly what it is.

这就是直，正是它的本来面目。

It's all dc power, it runs through into the inverters.

全是直，通向变。

For most things that run on DC, that's from the battery to whatever it's powering.

对于大多数使用直源的东西，所有能源都来自池。

Oh, I see. No, I don't know anything about that ACDC!

哦，明白了。不了解，我对交和直一无所知！

You, sir. You have DC running through your home.

先生 你家里走的就是直。

That direct current and, and the word direct means just that, and that's exactly what it is.

直这个词本身就解释了它的意思。

No, I don't know anything about that AC DC!

不，我对那个交，直一无所知！

But Edison believes that higher voltage AC is more dangerous than the direct current electric standard he's pioneered.

但爱迪生认为 高压交比他倡导的直更加危险。

Well, most of them convert the direct current electricity from the batteries into an alternating current.

它们大多数都是把池里的直转换成交。

In DC, or direct current, is exactly what it sounds like, the electrons go directly where they're headed without backtracking.

DC 是直，和它的名字一样，子始终沿着同一方向动。

An engine, for example, can be powered by direct current – which means that the electrons flow in one direction only.

例如，一台发动机，可以由直提供动力，这意味着子仅在一个方向上动。

Finally, the third and most efficient one is the Direct Current charging station which does exactly what it says.

最后是第三个级别，也是最有效的一个，那就是直充站，它的充效果正如字面意思。

DC appliances, and I think there's a real opportunity there, Chris.

AI：直，克里斯， 我认为那里有真正的机会。

While you may have direct current on big power lines, everything else is alternating current.

虽然大型输线路可能使用直，但他所有设备都使用交。

Precise stepper motors were traded in for continuous DC motors and encoders.

精密步进机被换成了连续直机和编码。

Ok, I've got my meter here set to DC voltage.

好的，我把仪表调到了直压档。

Edison was promoting direct current and Tesla was promoting alternating current.

爱迪生力挺直，而特斯拉则倡导交。

The magnetic field also  has been found to produce alternating currents rather than direct currents.

人们还发现磁场会产生交而不是直。
