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

这些都是因为个叫化还原的过程。

Redox reactions happen all the time in sediments.

化还原反应会直在沉积物中发生。

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

像这种情样，罪魁祸首可能是化还原反应，在这种反应中，子在两种或多种化合物之间转移。

Each cable connects two separate halves of a redox reaction.

每条缆连接两个单独的化还原反应。

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

因此，在这种情下，硫化氢可能在化还原反应中失子。

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.

我们基本上处于这样个阶段：基于大量的信仰飞跃， 我们断言，既然NAD水平和化还原位都在下降，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化还原反应的信息， 如果你还没有看过那集，你应该在看这个之前先看看那个。

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

我给你的化还原反应最基本定义就是：它只是在重新分配子以生成新的物质。

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

无论哪种方式， 您可能已经注意到些重要的事情：这是化还原反应！

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

这通常被定义为从化还原反应中产生能的装置。

So they combine those two words to make it redox.

于是他们将这两个词结合起来，形成“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化还原位（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，你应该解到化学反应是可以通过反应来描述的化还原反应。

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

但它们可能需要，对吧，因为它们仍然经历化还原位。

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.

化还原反应之所以如此强大、如此出色， 部分原因在于它们很复杂。

So in the case of this particular redox reaction, there usually is some kind of an electrolyte solution.

所以在这种特定的化还原反应中，通常会有种解质溶液。

Let's start with a typical redox reaction that happens in this alkaline battery as an example.

让我们以这种碱性池中发生的典型化还原反应为例。

And so anything that can improve redox, can potentially keep a cell around longer, functioning better.

因此， 任何能够改善化还原状态的因素，都有潜力延长细胞的寿命， 使其功能更佳。

So in redox reactions, to get the electrons to flow from whatever is losing electrons to whatever is gaining electrons, you need some kind of electrolyte solution.

所以在化还原反应中， 为让子从失子的物质流向获得子的物质，你需要某种解质溶液。
