摘　　要：影响地磁观测的因素很多,只有充分了解干扰的机制,才能对其数据进一步的处理。而在GM3,GM4提供秒采样数据后,观测数据中干扰数据的形态就可以非常清晰。本文就是利用秒采样的数据对几种常见干扰情况进行了描述,并使用软件对干扰数据进行剔除。There is a lot of factor to influence geomagnetic observation. Only full understanding of interference reason can further dispose of data. After GM3 and GM4 provide data of second sampling, form of disturbed data can be cleared. In this paper, using data of second sampling, some common disturbing conditions is described, and the disturbed data are winkled with software.
