the Antarctic ozone hole的意思|示意

Thee 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.

尽管每年春季出现在南极洲上空的臭氧空洞预计要到2073年才能恢复，但是极地以外地区的臭氧层预计到2048年就可以恢复到1980年以前的水平。

The global change appears to affect the Arctic and Antarctic regions such as the events of ozone hole in the Antarctic atmosphere and north moving of permafrost zone in the Arctic region.

同时，南极上空臭氧空洞的出现，北极地区冻土带的北移等都表明全球变化也在明显地影响着两极。

However, CFCs can persist for decades in the stratosphere-the Antarctic ozone hole is still there, though it's expected to grow smaller in coming decades.

然而，氯氟烃可以在同温层停留数十年，南极臭氧空洞就一直存在，虽然专家预计这个空洞会越来越小。

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.

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。

Since the discovery of Antarctic springtime ozone hole in 1985, there has been much international attention focused on the possible consequences of significant decreases of total ozone.

自1985年发现南极春季臭氧洞以来，对于臭氧大幅度减少所引起的可能后果与危害引起了国际关注。

Scientists have disclosed further details about a giant hole in the protective Ozone layer above the arctic. It matched the size of those found regularly over Antarctic .
