摘要
在定襄地震台地磁观测中,地磁仪易受到发电机的供电干扰,文章通过对观测数据的分析,进一步找出干扰的原因,并提出排除方法。同时,对影响地磁观测的其他因素进行分析,以提高地磁观测资料的精度,保证仪器运行的稳定性。
In the geomagnetic observation of Dingxiang Seismological Station ,magnetometer is apt to be interfered by electric power generator .By analyzing the observed data ,the cause of the interference is looked for and the elimination method is proposed .Moreo-ver ,we analyze the other factors which interfere the geomagnetic observation and try to improve the observation accuracy and guar-antee the stable operation of the instruments .
