摘　　要：利用河北省电磁辐射台网１９８８年—１９９２年的观测资料，对其间在各台项出现的异常频次及其累加特征进行了分析研究，并计算了每年的异常频次１０ｄ累加速率值Ｋ，发现其中震前半个月至一个月出现连续高值异常，并在临震前形成突出峰值，指出这一结果在短临预报中的意义。The anomalous frequence and its accumulated features of the stations between 1988 and 1992 were analyzed using the observation data of the electromagnetic radiation network in Hebei province,the 10 d accumulated rate K of anomalous frequence of every years were calculated.It was discovered that the successive high value anomaly occurred half a month to a mouth before the earthquakes,and the peak value occurred immediately before the earthquakes.
