In them, some molecules, called oxidizers, gain electrons.

在它们中，一些称为氧的分子获得电子。

But that means the reaction would have needed an oxidizer to take those electrons, something like oxygen.

但这意味着需要氧来吸收那些电子，例如氧气。

A rocket actually has its own fuel and oxidizer on board.

火箭实际上有自己的燃料和氧。

Like, in this case, it connects the hydrogen sulfide reducers in anoxic sediment with oxidizers closer to the surface.

同样，在这种情况下，它将缺氧沉积物中的硫氢还原与靠近表面的氧接起来。

When you combine those two with the fuel and the oxidizer, you get combustion, called thrust and you get about 2 million pounds of thrust out of those systems.

当你将这两者与燃料和氧结合时，它们会燃烧产生推力，这些系统大约会产生 200 万磅的推力。

And all of those oxidizers might harm the parasites, or injure infected cells just enough that they're gobbled up by the immune system — before the most dangerous forms of the parasite develop.

所有的这些氧物能伤害寄生虫，在寄生虫没长成有害个体之前，受过感染的细胞通过免疫系统吞噬它们。

What makes bleach so good at it's job is that it's a really strong oxidizer, meaning that the oxygen atom is really good at pulling electrons away from other compounds, making them break apart.

漂白之所以如此出色， 是因为它是一种非常强的氧，这意味着氧原子非常擅长将电子从其他合物中拉开， 使它们分解。
