答:我们也把新的温室气体释放到大气中,它们是20世纪以前不存在的,例如,氯氟碳(chlorofluorocarbons,CFC)过去用作推进剂,现在还广泛用于冰箱和空调的制冷剂。

在像氟利昂这样仍然在商业和工业中被广泛使用的氯氟碳物质显著减少之前,被损害的臭氧层是不能开始恢复的。
The damaged ozone layer can't start to heal until there is a significant reduction in chlorofluorocarbons, like Freon, that are still widely used in commerce and industry.
年长的读者们会记得有些车辆注入的“元老级气态制冷剂”为R 12,一种氯氟碳(英文简称CFC)的混合物。
Older readers will remember vehicles fitted with the "old gas" called R12, a compound of Chlorine, Fluorine and Carbon (CFC).
科学家们认为人类造成臭氧层破坏的主要原因是一些化学物质,像氯氟碳,当它们到达平流层后会分解成氯和溴,然后和臭氧发生化学反应从而破坏臭氧层。
The problem with the ozone layer is that when certain chemicals, like chlorofluorocarbons, reach the stratosphere, they break down into chlorine and bromine, which react with the ozone and destroy it.
And, this one here, some of you might recognize, is dichlorodifluoromethane. It's also known as a CFC.
而且在这些当中有些你或许认识,是二氯二氟化碳,它也是众所周知的氟利昂。
