重磁资料反演与其他地球物理反演一样也存在严重的多解性 ,要想得到好的结果 ,必须附加约束条件 ,而且尽可能是各种约束的组合。三维反演中多解性更加严重 ,同时与约束的结合又更加艰难。非线性的广义随机算法使反演求解过程稳定 ,约束条件容易结合 ,但计算速度和维数困难同样制约其发挥作用 ,采取针对性措施后 ,使三维反演进入实用化阶段 As with other geophysical inversion, gravity and magnetic data inversion has serious multiple solutions. To obtain good results, constraints must be added, and as far as possible, a combination of various constraints. The multi-solution is more serious in the three-dimensional inversion, and the combination with the constraint is more difficult. The nonlinear generalized stochastic algorithm makes the process of inversion solution stable and the constraints are easy to combine. However, the computational speed and dimensionality difficulty also play a role in it, and after the specific measures are taken, the 3D inversion is put into practical use
