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

这些都是因为一个叫氧还原的过程。

Redox reactions happen all the time in sediments.

氧还原反一直在沉积物中发生。

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

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

但它能需要，对吧，因为它仍然经历氧还原电位。

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还原反，发生什么？

Redox reaction is actually the combination of two reactions.

氧还原反实际上是两种反的结合。

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

像这种情况一样，罪魁祸首能是氧还原反，在这种反中，电子在两种或多种合物之间转移。

So they combine those two words to make it redox.

于是他将这两个词结合起来，形成了“氧还原”。

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

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

In our case, there's another type of reaction necessary called a redox reaction.

在我的例子中， 还有另一种必要的反， 称为氧还原反。

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

所以在这种特定的氧还原反中，通常有一种电解质溶液。

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，你该了解到电学反是以通过半反来描述的氧还原反。

Now I gotta point out here that the electrical potential of a redox reaction is related to its equilibrium constant.

现在我要在这里指出， 氧还原反的电势与其平衡常数有关。

And like carbon fixation it's also a redox reaction.

像碳固定一样， 它也是一种氧还原反。

The redox reaction is part of what runs batteries.

氧还原反是电池运作的一部分。

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

无论哪种方式， 您能已经注意到一些重要的事情：这是氧还原反！

Specifically, they are oxidation or redox reactions, the ones where electrons are exchanged.

具体来说，它是氧或氧还原反， 即交换电子的反。

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

氧还原反之所以如此强大、如此出色， 部分原因在于它很复杂。

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

让我以这种碱性电池中发生的典型氧还原反为例。
