根据《中国震例》所载 196 6年至 1985年以来 ,全国 Ms≥ 5 .0的 5 8次中强地震的《震例》研究成果 ,从应用的角度出发 ,探讨了动态跟踪预测未来中强地震活动“时”、“空”、“强”的活动规律 ,得出如下启示 :1)利用地震的前兆总体演变过程的阶段性以探讨定量预测其“活动时段”;2 )利用地震的前兆总体分布图象以探讨定量预测其“活动空间”;3)利用地震的前兆环的规模以粗略地预估其未来强震的“活动强度”。还初步探讨了利用它们的“场”、“源”演变的关联性 ,提出文中一些作法的物理意义之所在 According to the research results of the “earthquake cases” of 58 medium-strong earthquakes of Ms ≥ 5.0 that have been carried out in the “China Earthquake Cases” from 1996 to 1985, from the application point of view, the dynamic tracking prediction of the future We can draw the following enlightenment: 1) Make use of the stage of the overall evolvement of precursors of earthquakes to discuss the quantitative prediction of their “active periods”; 2) The precursors are generally distributed images to explore quantitatively predicting their “activity space”; and 3) using the magnitude of the precursor annulus of the earthquakes to roughly predict the “activity intensity” of their future strong earthquakes. It also tentatively explored the relevance of using their “field” and “source” evolutions and put forward the physical meanings of some practices in the text
