And one of the sources of this chemical, xylene, is wood tar.

而这种化学物质——甲苯来源之一是木焦油。

Xylol, x-y-l-y-l, refers to a group of atoms that are derived from a clear, flammable liquid called xylene, x-y-l-e-n-e.

甲苯，x-y-l-y-l，是源自一种名为甲苯，x-y-l-e-n-e，清澈易燃液体一组子。

And that's how the chemical xylene got its name.

这就是化学物质二甲苯名称由来。

I'm looking in the Oxford English Dictionary, which gives the definition, the hypothetical radical C8H9 of xylene and its derivatives.

我在《牛英语词典》中查找，这个词定义是甲苯及其衍生物假设性基团C8H9。

And the really cool thing is that xylene comes from the ancient Greek word for wood, xylon.

而且真很酷是，二甲苯这个词来源于古希腊语中“木头”，即xylon。

It's from the same root as xylene and xylol and that's probably the coolest thing I know about xylol.

它与二甲苯和木醇同源，这大概是我所知道关于木醇最酷事情了。
