由于上述原因平流层比对流层更容易被化学污染影响。

Because of the above reasons stratospheric more easily than the troposphere by chemical pollution.

例如，有的科学家就建议在有害化学物质到达平流层之前，使用山顶上的巨型激光束从根本上将它们分离。

For example, some scientists have suggested using giant lasers on top of mountains to basically break apart harmful chemicals before they reach the stratosphere.

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.
