摘　　要：1997年3月9日漠河日全食期间分别在漠河地磁台、北京怀柔地磁脉动观测站和三亚地磁台开展了地磁脉动的观测.本文重点分析了3月9日07∶00LT至11∶00LT日全食前后在漠河地区地磁脉动的观测资料,研究了日全食期间地磁脉动的主要特征,并对日全食期间地磁脉动的激发机制做了较深入的讨论.日全食期间地磁脉动的研究可以深入了解日全食期间太阳风-磁层-电离层的相互作用。Geomagnetic pulsations had been observed at Moho,Beijing and Sanya during solar eclipse on Match 9,1997. In this paper the data of pulsations observed at Moho region from 07∶00LT to 11∶00LT on Match 9 are analyzed. The major characteristics of pulsations during solar eclipse are studied. And the generation mechanism of pulsations during solar eclipse discussed. The study of pulsations during solar eclipse can realize interaction of solar wind-magnetosphere-ionosphere and invastigate the affect of solar activity on the space where mankind live in.
