摘要
Great attention has been paid to the Antarctic ozone hole and the decreasingtrend of atmospheric O<sub>3</sub> in recent years. The research report of the United KingdomStratospheric Ozone Review Group in 1991 pointed out that the total column of O<sub>3</sub> inthe mid-latitude of the Northern Hemisphere in spring has decreased by 8% in thelast 11 years. This is mainly due to the decrease of the stratospheric ozone.
