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

在它们中，一些称为氧化剂的分子获得电子。

Oxidizers are compounds that steal electrons from other chemicals in a reaction and they are what make combustion possible.

氧化剂是一种化合物，它在氧化反应中会从别的化学物质中偷取电子，它们也是燃烧的必要条件。

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化氢还原剂与靠近表面的氧化剂连接起来。

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

但这意味着该反应需要氧化剂来吸收那些电子，例如氧气。

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.

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

Oxidizers are also used to ignite rocket fuel and in the very short time that US rocket scientists thought about using this stuff as a propellant, they quickly learned that this idea was bad.

氧化剂也常被用来为火箭燃料点火，曾有很短一段时间美国的火箭专家们还考虑用它来做推进剂，但马上他们就意识到这个想法不可取。
