| 中文摘要 | 地球高层大气成分的长期变化受太阳黑子周,太阳活动程度和地磁活动程度等诸多因子所控制.本文利用国外有关高层大气成分的数据,分别讨论受上述控制因子影响的高层大气成分长期变化,讨论范围仅限氧半年周期变化. |
| 英文摘要 | The long-term variation of the atmospheric composition in the Earth’s upper atmosphere are controlled by 11-year cycle of the number of sunspots,varied solar and geomagnetic activity and so on. Satellite composition measurements showed that composition variations occurred.In this paper, the discussions are based on data from Satellite LDEF,and only represented in semi-annual variation of the atomic oxygen (LDEF,spent 5 years and 10 months in LEO, from 1984 to 1990).The results show that a semi-annual variation of the atomic oxygen is very clear,especially during the solar minimum (the mean annual sunspot number<20).The density of the atomicoxygen changes 40%一60%,and the total amount of variations is further enhanced by the increasing of the sunspots number, while the change is up to 87% during the solar maximum (in 1989, the mean annual sunspots number>120). |
