Researchers have long known that greenhouse gases might help the layer recover by cooling the stratosphere, which slows the rates of chemical reactions that destroy ozone.
长期以来，研究人员已经了解到：温室气体通过对同温层的冷却作用，可以放慢破坏臭氧层的化学反应速度，因此也许会有助于臭氧层的恢复。
Ozone is thus able to oxidize the outer lipid layer of malignant cells and destroy them through cell lysis.
因此，臭氧氧化能力，对恶性细胞的脂质层外，摧毁他们通过细胞裂解。
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.
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。
Because the toxicity of tetrachloromethane would destroy certain human and animal liver, and damage the ozone layer.
由于四氯甲烷具有一定的毒性会破坏人体及动物肝脏，并且会破坏臭氧层。
Because the toxicity of tetrachloromethane would destroy certain human and animal liver, and damage the ozone layer.
由于四氯甲烷具有一定的毒性会破坏人体及动物肝脏，并且会破坏臭氧层。
