| 摘 要： | 通过观测的极光与地磁扰动之间关系的分析，初步得出了南极中山站夜间（１１～２４ＵＴ左右）强、中、弱极光出现的频次在时间上的分布规律与地磁场扰动的关系，弱极光１０时开始出现， １５时左右频次达到高峰；中等极光１１时开始，１２到１９时出现的频次平稳， ２１到２２时频次达到高峰；强极光１６时开始， ２０到２１时极光频次达到高峰。各类极光出现的频次在时间上的分布与其所对应的地磁场扰动基本上是一致的，弱极光伴随着地磁场扰动幅度小；强极光伴随着地磁场扰动幅度大。极光的开始时间和地磁场扰动的时间不完全对应，这与极光的变化状态有关，这种变化状态受复杂的空间物理过程控制。 |

| Abstract: | The passage outlined of the dispersion law over time of the frequency that three different aurora(strong,middle,weak) had occurred during the night(GUT 11:00-24:00) in Antarctic Zhongshan Station has relationship with geomagnetic field disturbance by analysizing the observed aurora and disturbance. The weak aurora appeared at 10:00 o'clock and its frequency of occurrence reached the peak at 15:00;The middle appeared at 11:00,reached the peak during 21:00-22:00, and especially its frequency is stable at 19:00; the strong ones occurred at 16:00 and reached the peak during 20:00-21:00. The dispersion over time of frequency that all kinds of aurora occurred is approximately compliant with the disturance of geomagnetic field. The weak aurora accompanies disturbance of small amplitude. The strong aurora correspond with large amplitude. The time of aurora occurrence is partially the same as that of disturbance.This partially correspondence relates to the various status of aurora. Furthermore,this various aurora status is affected by space environment. |
