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

在它们中，一些称为剂的分子获得电子。

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

火箭实际上有自己的燃料剂。

To make any firework, you really need a fuel and an oxidizer.

要制作烟花的话，燃料剂是必不可少的。

Just like in black powder, you have potassium nitrate, and that's the oxidizer.

像黑火药一样，硝酸钾是剂。

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

但这意味着该应需要剂来吸收那些电子，例如气。

So you have a fuel, and you have the oxidizers, and that forms the basics of it.

燃料剂是烟火的基本组成。

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，它将缺沉积物中的硫氢还原剂与靠近表面的剂连接起来。

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

剂是一种合物，它在应中会从别的学物质中偷取电子，它们也是燃烧的必要条件。

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剂结合时，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。

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.

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，但马上他们意识到这个想法不可取。

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.

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