摘　　要：对大同－阳高６．１级中强震群余震频度的起伏变化进行了分析，认为该序列的频度变化与华北北部的较大地震对应较好，频度和强度的特征对未来震中的判断也有一定帮助，可作为监视华北北部地区地震活动的“窗口”The frequency fluctuation change of aftershocks of Datong Yanggao 6.1 moderately strong earthquake swarm is analyzed. It is considered that the frequency change of this sequence well corresponds to the greater earthquake in northern North China, and the frequency and intensity feature is also helpful to the judgement of future epicenters, which can be regarded as the “window” for monitoring the seismic activity in northern North China.
