摘要：

本文将我国首次南极考察得到的长城站地磁脉动资料与北京地区的同时地磁脉动观测资料作比较。对比分析表明 ,在磁静日中两个地区以平静的脉动为主 ,南极长城站有时出现Pc1 /Pc4- 5脉动 ,北京地区会出现 Pc3脉动。Pi脉动出现很少。但在磁扰日中 Pi型脉动出现次数明显增加 ,还会出现在对应的小时段上。不过长城站的 Pi脉动往往比北京地区强些。

Abstract:

In this paper a comparison of geomagnetic micropulsation observed in Antarctica and Beijing during the first Chinese exploration in Antarctica has been done. From the analysis it is concluded that during geomagnetic quiet days the quiet pulsation activity is dominated in both areas, and Pc1/Pc4-5 pulsations occur sometimes in Antarctica and Pc3 pulsations in Beijing, and that Pi pulsations hardly occur. There is no corresponding pulsation in both areas in universal time. However, during geomagnetically disturbed days the occurence of Pi pulsations in both areas increases and they have a good corresponding relation, but those in Antarctica are stronger than that in Beijing.
