摘要
利用嘉峪关地磁垂直分量1993-1998年的资料,系统分析了嘉峪关地区地磁场Z分量的年变形态。结果表明:地磁低点位移异常与地磁z分量的季节性变化有关,与地磁场的日变幅度有关。
We use the documents about the geomagnetic vertical component of Jiayuguan from 1993 to 1998 to comprehensively analyze the annually changed configuration of the geomagnetic Z component in this area. The result shows that the abnormity displacement of the low points of geomagnetic record is related to the seasonal changes of geomagnetic Z component and the daily changes of the geomagnetic field.
