该研究表明，这种未受现行的保护臭氧层法规管制的气体，现在是人类活动所产生的破坏最大的臭氧层破坏物质。
The gas, which is not covered by existing regulations to protect ozone, is now the largest ozone-depleting substance produced by human activity, the research shows.
尽管氯氟烃已经被禁用，但是由于多年前排出的气体，臭氧层仍然继续被损耗，目前在地球两极上方都有臭氧层空洞。
Although CFCs have been banned, the ozone layer is still being depleted from gases released many years ago, and holes exist above both poles.
《蒙特利尔议定书》规定禁止使用各种消耗臭氧层的化学物质，使臭氧层保护的远期前景显得非常良好。
The Montreal protocol, which banned various ozone-depleting chemicals, has left the ozone layer’s long-term prospects looking quite bonny.
平流层大气包含臭氧层，臭氧层由紫外线照射导致的三个氧原子结合成的臭氧分子组成。
The still air of the stratosphere contains the ozone layer, which was created when ultraviolet light caused trios of oxygen atoms to bind together into ozone molecules.
在过去30年里，他们通过跟踪测定臭氧层中化学物质的含量来估算臭氧层的破坏程度。
They point to the way their estimate of chemically destroyed ozone closely tracks the amount of chemicals in the hole during the past 30 years.
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。
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.
晒伤增多的一个原因可能是臭氧层空洞，而臭氧层是保护地球不受太阳紫外线危害的保护层。
One reason for the rise in sunburn could be the hole in the ozone layer - the protective layer that shields the Earth from the sun's harmful ultraviolet rays.
氢氯氟化碳以替换破坏臭氧层物质的形式被引进进来，尽管氢氯氟化碳不会破坏臭氧层，但是它却是强有力的全球变暖催化剂，被当成“超级”温室气体。
Introduced as replacements for ozone depleting substances, HFCs do not damage the ozone layer but are potent global warming agents and considered 'super' greenhouse gases.
从臭氧层的实际变化中除去正常情况下臭氧层的变化（对照），这个研究团队发现“自20世纪90年代以来臭氧层空洞缩小趋势”有一个系统性的机制。
Subtracting their estimate of the natural changes in ozone from actual changes, the group finds “a clear upward trend since the late 1990s” in the hole's ozone that represents “a systematic rebound.”
到2048年，极地地区外的臭氧层将恢复到1980年以前的水平，但每年春季出现的南极臭氧层空洞要在2073年才能得到恢复。
The ozone layer outside the polar regions is projected to recover to pre-1980 levels by 2048, although the annual springtime ozone hole over the Antarctic is not expected to recover until 2073.
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.
近年来，臭氧层因受到消耗臭氧层化学物质（简称ODS）的损耗，而造成的平衡破坏、浓度降低成为全球性的环保热点问题。
Ozone Layer was worn down by ODS recently, which resulted in the breaking of ozone layer′s balance and the decreasing of ozone layer′s thickness.
因此，探析臭氧层损耗的原因，对于拯救臭氧层，保护地面生物是非常重要的。
Therefore. it is very important to find out the causes of the loss of the ozonosphere in order to save the ozonosphere and protect the land living things.
