在震群特性研究中引入加卸载响应比理论，选取新疆82个震群为研究样本，以加卸载响应比Y≥2．0作为判定前兆震群的指标，对作本的震群特性进行了分析判定。结果表明，判定为前兆震群的26个震群中有20个对应了其后一年内发生的5级以上地震，异常报准率为76．9％。
Introducing the theory of loading-unloading response ratio into the study of swarm characteristics, 82 swarm swarms in Xinjiang were chosen as the research samples. The swarm characteristics of swarm were evaluated by using the unloading response ratio Y≥2.0 as the indicator of the swarm. Analysis and judgment. The results show that 20 out of 26 earthquake swarm determined as precursory swarms correspond to earthquakes of magnitude 5 above in the following year with anomaly anomaly rate of 76.9%.
