| Abstract: | 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. |
