| 英文摘要 | From the finite element equation of anisotropic elastic waves, an expression is derived for directly calculating the Jocobi matrix. It has the same form as the finite element for-ward modeling equation. So all the elements of Jocobi matrix can be got through finite element for-ward modeling. To improve the efficiency and accuracy of the inversion system, problems such as the efficiency and accuracy of the forward modeling system, absorbing boundary conditions and so on, are also studied. Finally, anisotropic model inversion is carried out with the finite element inversion system. The inversion results of a stratified model and a transversely heterogeneous model accord with real models very well, even though the initial modes have great deviations. |
