摘要
通过对波速比计算中的一些不确定因素如时间服务、震相辨别、震源深度、计算方法和介质的非均匀性的仔细分析 ,认为主要由计算方法的局限性和介质的非均匀性造成。作者经过多年的地震预报实践 ,提出在研究普适性的同时 ,结合孕震模式探索地震前波速比异常的特殊性。
Through analyzing the nondeternistic factors in calculation of Vp/Vs in detail, such as, time service, phase identification, focal depth, calculation method and medium inhomogeneity, it is thought that the nondeterministic factors mainly are brought about by limitations of calculation method and medium inhomogeneity. Based on practice of earthquake prediction in many years, the author puts forward that the particularity of Vp/Vs before earthquake should be approached in combination with seismogenic model, while studying generality.
