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(H_(ax)、H_(ay)、Z_a)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。
In this paper, we study the magnetic field of a uniformly magnetized polyhedron, and establish the normalized analytical expressions of the total magnetic anomalies (ΔT) and its components (H_ax, H_ (ay), Z_a). This is the general formula for the magnetic field of any magnetic body surrounded by a flat surface. It can be simplified by a variety of magnetic rules of the magnetic field formula. In this paper, a finite length tilted plate-shaped body magnetic field, for example, illustrates this simplification process. The analytical expression for the polyhedral magnetic field in this paper is expressed by the coordinates of the corner point and the values of the magnetic parameters. Given that it is a double sum-of-sides equation, it is convenient to calculate on an electronic computer.
