摘　　要：首先扼要介绍了电极法地震电磁辐射的仪器性能、干扰概况和干扰与异常的识别。通过大量资料相关分析表明，雷电、磁暴等空中电磁扰动信号，以及气温、降水等气象因素，都不是电极法电场观测地震电磁辐射的明显干扰因素；当地低空特强雷电和布极区附近的较大电气设备启闭，可造成干扰，但此干扰可以识别和排除。This paper briefly introduces the performance of seismic electromagnetic radiation instrument of electrode,general situation of interfrence,and the identification of interfrence and anomalies.The correlation analysis of a large amount of data shows thar the interferely electic signs of thunder -lighting and magnetic storm in the air,meteorologic factors of tempreture and precipitation are not obvious interfrence factors on seismic electromagnetic radiation of electrode.The extra strong thunder-lighting in low air in the local rrea and turning on/off large-scale electric equipments around the electrode may cause an interference,but it can be distinguished and eliminated.
