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

而种化学物质——甲苯来源之木焦油。

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.

甲苯酚，x-y-l-y-l，指源自种名为甲苯，x-y-l-e-n-e，清澈易燃液组子。

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

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《牛津英语词典》中查找，个词定义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，二甲苯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，大概我所知道关于木醇最酷事情了。
