| 摘 要： | 应用灰色系统理论的GM模型对短边测距资料进行了处理并识别异常,发现在绝大多数中强地震前,如1989年大同6.1级地震,1991年大同5.8级地震,1991年唐山4.8级、5.1级地震,1995年唐山古冶5.0级地震,1996年包头6.4级地震,1998年张北6.2级地震前,均有比较明显的异常显示.对所建模型的精度进行了检验,证明这一方法识别异常可靠,可用于地震预报.

| Abstract: | The GM model of grey system is used for data processing and distinguishing anomalies of cross fault shortedge ranging.It is found that there were clear anomalies before many moderately strong earthquakes,for example,Datong earthquake of 6.1 in 1989,Datong Earthquake of 5.8 in 1991,Tangshan Earthquakes of 4.8 and 5.1 in 1991,Tangshan Guye Earthquake of 5.0 in 1995,Baotou Earthquake of 6.4 in 1996,and Zhangbei Earthquake of 6.2 in 1998. The accuracy of the model is tested,and it is proved that this method for distinguishing anomalies is reliable and valuable in earthquake prediction. |
