| 摘 要： | 研究了华东、华南地区1970年以来4次6级左右地震前后地震波某些参数的变化特征。定义了单发前震。讨论了模拟记录的数字化、震源与介质模型的简化、理论量板的制作、震级和震源的测定及其传递环节等的误差估计。给出了空区、条带、前震的某些地震波判别指标。

| Abstract: | Some seismic wave parameters befor and after 4 earthquakes about M_S6 in East China and South China area was analyzed in this paper.The single foreshock was defined.The digitilisation of the analog record,simplification of focus and medium model,development of theoretical measuring scale,determination of magnitude and focum and error estimation of transfer link were discused in detail.some distinguishing elements of gap,belt and foreshock of seismic wave were given |
