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

全是直电，通向变器。

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

这就是直电，正是它的本来面目。

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

然后变器将其从直电转换为电。

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

不，我那个电，直电一无所知！

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

先生 你家里走的就是直电。

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

直电这个词本身就解释了它的意思。

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

哦，明白了。不了解，我电和直电一无所知！

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

于大多数使用直电源的东西，所有能源都来自电池。

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将信号转换成可用的直电。

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 高压电比他倡导的直电更加危险。

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

它们大多数都是把电池里的直电转换成电。

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

DC 是直电，和它的名字一样，电子始终沿着同一方向动。

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，那就是直电充电站，它的充电效果正如字面意思。

It stands for transcranial direct current stimulation.

它代表经颅直电刺激。

Until now, we've mainly been talking about DC, or direct current.

到目前为止，我们主要讨论的是 直电或直电。

There a reason you're on direct current?

你们怎么还用直电？

Dc's kind of yesterday's news for this sort of thing.

直电比较落后。

" D.C." stands for the District of Columbia.

” “直电。 ” 代表哥伦比亚特区。

Alternating current is considerably more efficient than direct current.

电比直电效率高得多。

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

虽然大电源线上可能有直电，但其他一切都是电。
