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

在，一些称为氧剂的分子获得电子。

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

火箭实际上有自己的燃料和氧剂。

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

要制作烟花的话，燃料和氧剂是必不可少的。

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

就像黑火药一样，硝酸钾是氧剂。

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氧剂来吸收那些电子，例如氧气。

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

燃料和氧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，在这情况下，将缺氧沉积物的硫氢还原剂与靠近表面的氧剂连接起来。

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

氧剂是一物，在氧应会从别的学物质偷取电子，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和氧剂结时，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。

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还考虑用来做推进剂，但马上他就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， 是因为是一非常强的氧剂，这意味着氧原子非常擅长将电子从其他物拉开， 使分解。
