） Abstract： Modeling seismic wave field with the Finite Difference Method (FDM) is an effective method to study the seismic wave propagation in the earth medium
When we model seismic wave field in the laboratory, the finite difference grids are restricted in the artificial boundary
So it should introduce the artificial boundary conditions
This paper adopts Clayton_Engquist_Majda 2nd absorbing boundary conditions and realizes the arithmetic with MATLAB
The MATLAB codes are direct and accord with our thinking custom
So it can provide the friendly and succinct programming environment and is easy to communicate with other
Keywords： finite difference method, seismic wave field, numerical modeling, absorbing boundary conditions, MATLAB 下载PDF阅读器 PDF全文下载： 初稿 （ 765 ） 作者简介： 通信联系人： 【收录情况】 中国科技论文在线： 陈敬国
