查询词典 sepia paper

In this paper, we research the imaging problems beneath volcanic area. We sort common asymptotic conversion point gathers and perform velocity analysis to establish the initial velocity which will be used in PSTM. By scanning migration velocity and V p/ V s, we get the optimum migration velocity and
