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。

关 键 词:电磁辐射  异常频次  累加速率

Abstract: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.
Keywords:Electromagnetic radiastion  Anomalous frequence  Accumulated rate
