| 摘 要： | 本文研究了均匀磁化多面体的磁场,建立了总磁异常（△T）及其各分量(Hax、Hay、Za)的规格化解析表达式。这是由平表面围成的任意磁性体磁场的一般式。由它可以简化出各种规则磁性体的磁场公式。文中以有限长倾斜板状体磁场为例,说明了这个简化过程。 本文的多面体磁场解析式是由角点坐标和磁参数值表示出来的。鉴于它是边和面的二重累加和式,因此,在电子计算机上计算将十分方便。

| Abstract: | The magnetic fields of uniformly magnetized polyhedra are studied, and normalized expressions for evaluating their vertical, horizontal and total intensity anomalies （Za, Hax, Hay and △T） are derived. As an example for illustration, the process is given of reducing it to the equation of the magnetic anomalies of a plate with limited dimensions.The magnetic anomalies of polyhedra are represented in this normalized expression as the functions of their magnetic paramenters and the co-ordinates of their corner points. Since it is a twofold summation of the sides and the faces of the polyhedron, this expression will be very convenient for operating on the computer. |
