摘要
对 1 997年 3月 9日的漠河日全食以及几乎遍布整个中国境内的日偏食地磁效应作了详尽地分析 ,得到了分布广泛的日食地磁效应 .其特征表现为 ,日食期间 H分量呈下降变化 ,其变化幅度沿纬度呈对称分布 ,中心约位于 3 3°N处 .
The geomagnetic effects of the total solar eclipse in Mohe area and the partialeclipse, occurred on March 9, 1997 in China are analysed in this paper. The geomagnetic effects of the eclipse widely in China area are obtained, which show H component decreases obviously along latitude, showing a symmetric distribution by the center of some 33°N during the eclipse time. These results of geomagnetic effects of solar eclipse are the newest in recent years observed in the largest area in China.
