The scientists say this is the most distant observation of PAHs ever.

科学家表示，这是迄今为止观测到的距离最遥远的多环芳香烃。

PAHs are made up of fused rings of carbon atoms-think of chicken wire.

多环芳烃是由碳原子的熔合环组成的——想想铁丝网。

Because PAHs form with the help of free radicals, and antioxidants could slow down that process.

因为多环芳烃需要借助自由基生成，而抗氧化物质能减缓这一过程。

“啪嗒啪嗒啪啪啪。 ” 试试吧。 伟大的。然后，用这些，“pa ta ka pa ta ka paw” 。 好的。
