傅红笋 %A 韩波 %J 地球物理学报 %D 2005 %I %X Combining the Tikhonov regularization method for ill-posed problems with the widely convergent homotopy method applied to the inversion process of operator identification,a new strategy-regularization-homotopy method is proposed for the inversion of 2-D wave equation,which is suitable for the nonlinear,ill-posed and multi-extremum seismic inverse problem.In order to restrain noises and improve the quality of inversion,a well log constraint regularization-homotopy method is further constructed.Lots of numerical simulations indicate our method's effectiveness. %K 2-D wave equation %K Velocity inversion %K Tikhonov regularization %K Homotopy method %K Well-log constraint
