The state-of-the-art in numerical modeling including surface topography with finite-difference method
地震波有限差分数值模拟框架下的起伏地表处理方法综述

As a tool for understanding the regulation f wave propagation in complex media and examining the effects of different kinds of methods,seismic numerical modeling plays an important role in modern geophysical prospecting.This paper briefly introduced several modeling methods including surface topography with finite-difference in recent 30 years.Two implementation methods are proposed: derect method which includes rotated coordinate method,vacuum method and general imaging method and indirect method.Our aim is to find the suitable method to solve the adapted questions.
