Redox reactions happen all the time in sediments.

还反应会一直在沉积物中发生。

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

这些都是因为一个叫还程。

Each cable connects two separate halves of a redox reaction.

每条电缆连接两个单独一半还反应。

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

因此，在这情况下，硫氢可能在还反应中失去了电子。

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

具体说，它们是或还反应， 即交换电子反应。

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

这通常被定义为从还反应中产生电能装置。

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

像碳固定一样， 它也是一还反应。

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

还反应之所以如此强大、如此出色， 部分因在于它们很复杂。

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

让我们以这碱性电池中发生典型还反应为例。

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

像这情况一样，罪魁祸首可能是还反应，在这反应中，电子在两或多合物之间转移。

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，你就会知道电学反应是我们用半反应描述还反应。

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

在我们例子中， 还有另一必要反应， 称为还反应。

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事情：这是还反应！

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， 还反应电势与其平衡常数有关。

When an electric current is applied, a redox reaction occurs in the solution and atoms of the coating metal are deposited on the cathode.

当施加电流时， 溶液中会发生还反应，涂层金属子会沉积在阴极上。

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.

我之前已经告诉你有关还反应信息， 如果你还没有看那一集，你应该在看这个之前先看看那个。

But before any redox reaction can be used to text your boyfriend or girlfriend or whatever, we need to know how much voltage it can generate.

但是在任何还反应可以用给你男朋友或女朋友发短信之前，我们需要知道它能产生多少电压。

When we discussed it as a redox reaction a few weeks ago, we described it as a one way, complete reaction because that's all we needed to understand right then.

几周前，当我们将其作为还反应进行讨论时，我们将其描述为一单向、完全反应， 因为这就是我们当时需要了解全部内容。
