摘　　要：叙述了1982年以来在首都圈附近超低频(ULF)电磁辐射观测网的建设,该台网以埋地电极接收地下电场变化为主,用感应线圈接收磁场变化为辅。采用选择观测频段、埋深电极、隔直、滤波等技术措施减小干扰。给出了记录资料异常图形的分类及处理方法。研究了一些相关因素的可能影响。A group of ultra-low frequency electromagnetic radiation observation network has been built in the Capital circle region since 1982. The network is mainly used to observe electric field change by electrode under the ground. At the same time, it is used to accept magnetic sign. Using some techniques, such as the selected observation frequency band, deep-buried electrode, filtering of waves etc, can reduce the interference. Some possible effects of related factors are studied and the classification and processing methods of anomalous figures are given in the recorded data.
