非均匀磁化、任意形状的磁性体的磁场计算是经典场论还一直未解决的问题.当磁性体磁性较强、形态复杂、埋藏较浅时,特别是穿过强磁性体的井中磁测结果,不均匀磁化对磁异常影响很大,不可以忽略. 最近在我国先后发表过计算任意形状强磁性三度体磁场的论文其中黄诚的泊松公式面积元素法,是根据离散化概念提出的,可用来计算三度体全空间的磁场.用近似程度不同的两套公式 Magnetic field calculation of non-uniform magnetization and arbitrary shape magnetic body is a problem which has not yet been solved by the classical field theory.When the magnetic body is strong magnetic, complex shape, shallow buried, especially in the magnetic field through the ferromagnetic body , Non-uniform magnetization of the magnetic anomalies have a great influence, can not be ignored.Recently in our country has published over the magnetic field of a third-order magnetic field calculated arbitrary shape which Huang Cheng Poisson formula area element method is based on the concept of discretization , Which can be used to calculate the magnetic field of a full-scale third-degree space with two sets of formulas of different approximations
