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

些都是因为一个叫氧化还原的过程。

Redox reactions happen all the time in sediments.

氧化还原反应会一直沉积物中发生。

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化还原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化学家们如今称作氧化和还原的反应。

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

像情况一样，罪魁祸首可能是氧化还原反应，反应中，电子两或多化合物之间转移。

Each cable connects two separate halves of a redox reaction.

每条电缆连接两个单独的一半氧化还原反应。

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

因此，情况下，硫化氢可能氧化还原反应中失去了电子。

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，它也会降低氧化还原电位(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水平和氧化还原电位都下降，我们认为以某形式补充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化还原反应的信息， 如果你还没有看过那一集，你应该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.

我给你的氧化还原反应最基本定义就是：它只是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!

无论哪方式， 您可能已经注意到一些重要的事情：是氧化还原反应！

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

通常被定义为从氧化还原反应中产生电能的装置。

It will make the oxidative reduction potential negative.

它会使氧化还原电位变为负值。

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“氧化还原”。

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化还原电位（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.

如果你听，你应该了解到电化学反应是可以通过半反应来描述的氧化还原反应。

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化还原电位。

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化还原反应时，会发生什么？

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

氧化还原反应之所以如此强大、如此出色， 部分原因于它们很复杂。
