| 中文摘要: |
| 从电磁场满足的微分方程、边值问题和变分问题出发,针对有限元正演中形成的大型、稀疏、对称、正定复系数严重病态矩阵,采用SSOR-BICGSTAB迭代法进行求解,建立了基于倾子响应的大地电磁二维快速正演算法。通过对典型二维地电模型的大地电磁倾子响应模拟,总结了倾子响应的异常规律及影响特点,为实际工作提供理论指导。 |
| 英文摘要: |
| In From the differential equation, electromagnetic boundary value problems and variational problems, according to finite element modeling of the formation of large, sparse, symmetric, positive definite complex coefficient is seriously ill conditioned matrix, are solved using the SSOR-BICGSTAB iterative method, realized the tipper response of MT two dimensional fast forward calculation based on. Realization of the MT two dimensional forward modeling problem and some important conclusions are drawn, and provides a theoretical guidance for the practical work. |
