摘要
本文应用灰色系统理论的关联分析方法,从系统的整体观点出发,对唐山地震的前兆资料进行综合处理。结果表明,震前前兆综合映震场与临震场的关联度随震源应力场的加剧而逐步趋升且逼近1,这一特征可作为临震状态的标志。该方法对于地震预报具有一定的实用价值。
From the viewpoint of the systematic entirety, the precursory data of Tangshan earthquake M = 7.8 are processed by using the correlation analysis method of grey system theory in this paper. The results show that the values of the correlation degree between the synthetic precursory field and impending field increase gradually nearby 1 with strengthening the source stress field from 1971-1975. which may be regarded as a mark of earthquake occurrence. It indicates that method is of a certain practical significance in earthquake prediction.
