| 摘 要： | 根据磁异常反演磁性介质下界面,属于非线性问题,一般很难直接求解.本文采用将非线性问题线性化措施,建立起线性离散磁模型,然后应用线性规划的正则算法,设计了迭代求解方案.该方法不要求已知界面起伏的平均深度,只要求假定界面是连续的及磁性沿横向变化.算法便于对解施行物理约束,具有收敛快,精度高的特点.

| Abstract: | The inversion of the lower interface of magnetic media on the basis of magnetic anomaly is a nonlinear problem. which it generally difficult to solve directly. Through lineatrzation of nonlinear problems. the authors established the linear discrete magnetic modeland, using regular algorithm of linear programing, designed a scheme for iterative solution,which does not require sverage depth of known interface relief, and only needs the auppositionthat the interface is continuous and that magnetism changes laterally. As the algorithm isready to exert physical constraint upon the solution. the method is characterized by rapidconvergence and high precision. |
