| 摘 要： | 本文在文献1]的研究基础上进一步分析海洋和电离层发电机对佘山台L的影响。资料分别按月、季节和年以及太阳活动性分组进行的细致分析,结果表明海洋发电机对Z分量的L有一稳定的影响,L的季节变化主要起源于电离层发电机。L的海洋部分不随太阳活动性改变,太阳活动对L的影响比对S的小。

| Abstract: | On the basis of reference 1], the effect of oceanic and ionospheric dynamoson the geomagnetic lunar daily variation L at Sheshan station are furtheranalyzed in this paper. The average forms of L of years, seasons and months areseparately obtained from the data (1960--1978), and analyzed in detail. The effe-cts of solar activity on L'are also studied. The result shows that oceanic dynamohas a steady 'and significant contribution to vertical component Z. The seasonalvariation of L may primarily arise from ionospheric dynamo, and its oceanic partdoes not vary with the solar activity. The influence of solar activity on L is fou-nd to be smaller than its influence on S. |
