| 摘 要： | 本文首次利用常微分方程定性理论对平流层O3、O动力系统的平衡性质进行了讨论.结果表明,如果在平流层O3的主要分布高度内,大气扩散作用小于光化学作用,那么平流层的O3层处于稳定状态;反之,平流层的O3层将遭到破坏.利用这一机制,我们可以解释南极平流层O3的季度变化规律和每年9-10月份出现的南极O3洞.

| Abstract: | The equilibrium properties of O3, O dynamic system in stratophere are discussed by the qualitative theory of ordinary differentical equations. The results indicate that if atmospheric diffusion effect is less than photochemistry effect in the altitude region where most of the total ozone column is located, then the ozone layer in stratosphere stably exists; on the contrary, the ozone layer in stratosphere is seriously destroyed. We can explain the Antarctic ozone seasonal variation in stratosphere and the Antarctic ozone hole that appears' from September to October every year with this mechanism. |
