And that's all because of a process known as redox chemistry.

些都是因为一个叫氧的过程。

Redox reactions happen all the time in sediments.

氧反应会一直在沉积物中发生。

So rechargeable batteries give us a temporary solution to this problem by making the oxidation-reduction process reversible.

所以充电电池通过可逆转的氧过程暂时解决了个问题。

What happened in Volta's cell is something chemists now call oxidation and reduction.

Volta的电池中发生的就是学家们如今称作氧和的反应。

Like in this case, the culprit could have been a redox reaction, in which electrons get transferred between two or more compounds.

像种情况一样，罪魁祸首可能是氧反应，在种反应中，电子在两种或多种合物之间转移。

Each cable connects two separate halves of a redox reaction.

每条电缆连接两个单独的一半氧反应。

So, in this case, the hydrogen sulfide could have lost electrons in a redox reaction.

因此，在种情况下，硫氢可能在氧反应中失去了电子。

And even when you add hydrogen gas to regular water, it will drop the ORP.

即使你向普通水中加入氢气，它也会降低氧电位(ORP)。

We're basically at the point where we're taking a lot of leaps of faith and saying, because NAD levels are going down and redox potential is going down, we believe supplementing NAD in one form or another makes sense.

我们基本上处于样一个阶段：基于大量的信仰飞跃， 我们断言，既然NAD水平和氧电位都在下降，我们认为以某种形式补充NAD是有道理的。

I've told you about redox reactions before and if you haven't seen that episode yet, you should probably go watch that before you watch this.

我之前已经告诉过你有关氧反应的信息， 如果你没有看过那一集，你应该在看个之前先看看那个。

And the most basic definition I can give you of a redox reaction is it's just shuffling electrons around to make new things.

我给你的氧反应最基本定义就是：它只是在重新分配电子以生成新的物质。

Either way you might have noticed something important: this is a redox reaction!

无论哪种方式， 您可能已经注意到一些重要的事情：是氧反应！

Which is generally defined as an apparatus that generates electrical energy from a redox reaction.

通常被定义为从氧反应中产生电能的装置。

It will make the oxidative reduction potential negative.

它会使氧电位变为负值。

So they combine those two words to make it redox.

于是他们将两个词结合起来，形成了“氧”。

And what's declining as we age should less be thought of as a reduction in NAD and should more be thought of as a reduction in what's called redox potential, the ability to do what I just said.

随着我们年龄增长而下降的， 与其说是NAD的减少， 不如更多地理解为所谓的氧电位（redox potential）的降低，即我刚才提到的那些功能的减弱。

If you were listening, you learned that electrochemical reactions are redox reactions that we describe in terms of half reactions.

如果你在听，你应该了解到电学反应是可以通过半反应来描述的氧反应。

But they might, right, because they still undergo redox potential.

但它们可能需要，对吧，因为它们仍然经历氧电位。

So what happens when your iron rust is actually known as a redox reaction?

所以当你的铁生锈实际上被称为氧反应时，会发生什么？

Part of what makes redox reactions so powerful, and powerfully excellent, is that they are complicated.

氧反应之所以如此强大、如此出色， 部分因在于它们很复杂。
