| 英文摘要 | One of the keys for efficient numerical modeling of frequency-domain acoustic wave modeling is to solve a large sparse and linear system, which the coefficient matrix have the character of non-symmetric and non-positive. To improve the convergence property and robustness of numerical modeling, we have developed a new regularized preconditioning iterative method that enforced the sparsity of solutions in frequency-domain. The construction of preconditioner requires the regularization for large sparse original problem firstly, which is called regularized system. Then we regarded the approximate iterative solution of the regularized system as initial value of original problem. The numerical computational experiments including the synthetic complex model indicate that the extra computation of the method is almost negligible. By comparison with the storage space of LU decomposition, the regularized preconditioning iterative algorithm is dramatically decreased. Besides, effectiveness and convergence rates of regularized preconditioning iterative solvers are greatly improved by regularized preprocessing. |
