| 摘 要： | 中国首次南极考察队于1985年1月至2月在南极洲中国长城站进行了地磁脉动观测。作者采用微型计算机和数字声图仪对记录的资料进行了处理,得到Pc1-4以及Pi2等类型脉动的形态和动态谱。同时,统计了Pc1脉动发生频次的日变化特征以及与K_p指数的相关性。最后,讨论了Pc1脉动中H和D分量的不对称性等某些不常见的现象。

| Abstract: | The First Chinese Antarctic Expedition. Team recorded geomagnetic pulsations at Great Wall Station during Jan.-Feb., 1985. We processed these data by use of microcomputer and sonograph. Some results are presented in this paper including the morphology and dynamic spectrum of recorded types Pe1-4 and Pi2 etc. Meanwhile, some statistical properties of Pc1 are illustrated, such as the diural variation of bccurence frequency and its correlation to KP index. Asymmetry between H and D components of Pcl is discussed. |
