摘　　要：利用小震调制比的时间扫描方法对异常进行跟踪分析,通过对震例的研究发现,小震调制比的时间异常变化与宁夏及邻区的中强地震具有一定的对应关系。进一步分析认为,研究震前小震调制比的时间异常变化对把握宁夏及邻区中强震的发生具有一定的指示意义。The space anomaly of small earthquakes modulation ratio is compared and analyzed. By comparison, some relationship between earthquakes modulation time anomalies and moderate earthquakes in Ningxia. Further analysis of studies suggest that it has some implications for the use of small earthquakes before the earthquake modulation time to grasp the abnormal changes in adjacent areas of Ningxia.
