| 摘 要： | 用Winch提出的地磁太阴日变化分析方法确定佘山地磁台的地磁太阴日变化的O1分量L(O1).首先把佘山台 196 0～1988年D,H和Z各分量的时均值资料做为整体分析年平均变化,然后按季节和太阳活动性细分后进行计算分析.讨论了L(O1)的基本特征和季节变化、电离层和海洋发电机效应对L(O1)的影响以及太阳活动对L(O1)的贡献,并与国外一些地磁台的结果进行了对比分析.

| Abstract: | The O 1 component of geomagnetic lunar daily variation is analyzed by the generalized method of Winch.First,the annual mean variation of D,H and Z elements at Sheshan Observatory during 1960-1988 are calculated by analysis of the data of hourly average values,then the data are re-analyzed after subdivision of quiet, medium and active periods according to seasonal and solar activities.The general features and seasonal variation of L(O 1),the effects of the ionospheric and the oceanic dynamo on L(O 1) and the contribution of solar activity to L(O 1) are discussed,and the comparison analysis of the results is made between this work and those of some observatories abroad. |
