摘要

地磁观测是地震预报中重要的前兆手段之一。识别干扰,排除干扰,对保证观测资料的可靠尤为重要。我们根据泾县地震台地磁核旋观测过程中遇到的问题,利用对比观测方法,对观测数据进行分析,结果表明该仪器工作正常,性能稳定,精度很高;同时指出,在观测过程中应注意的一些问题,并排除了影响泾县地震台地磁观测的干扰源。
Geomagnetic observation is one of the most important precursor methods of earthquake prediction. It is particularly important to identify and remove the interference in order to ensure reliable data. According to problems occurred in the observation of nuclear precession magnetometer in Jingxian Seismic Station, we analyze on the data using contrast observation method. The results showed that the equipment is high accuracy and stable. And we also pointed out that some issues should be paid attention. In addition, the magnetic interference source in the geomagnetic observation of our station has been eliminated.
