| 摘 要： | 对哈雷、百武和海尔-波普三颗彗星在不同时间、不同位置的情况下5次过近地点可能 引起的对地球磁层影响进行了资料分析和统计研究,指出,根据等离子体彗尾的特征,完全 可以对磁层引起扰动,但是这种扰动有严格的制约条件,不是每次彗星过境都很容易对地球 电磁环境产生影响。

| Abstract: | During the transit of comets (Halley, Hyakutake and Hale-Bopp), some data analysis and statistical research have been made and the possible influence of magnetospheric environment resulted from the 5 times transit of the 3 comets have been discussed. According to the feature of cometary plasmas, the possibility is pointed out in this paper that cometary tail is able to cause the magnetospheric disturbance. However, the disturbance is restricted by some rigorous condition, and it is not essay for the comets to possess such condition during their transit. |
