摘要

本文提出了一种求解低频磁场中旋转球形薄壳体屏蔽问题的方法．在平均边界条件的基础上，导出了旋转球形薄壳体屏蔽边值问题的解，之后得到了球形薄壳体中心传输系数的公式，最后应用ＦＯＲＴＲＡＮ语言编程上机计算，找到了磁场振荡频率、旋转速度与传输系数的关系等重要屏蔽特性．

Abstract

In this paper

a method of solution for the shielding equation of a rotating thin spherical shell in a low frequency magnetic field is presented.On the basis of averaged boundary conditions

the solution of the boundaryvalue problem for the shielding of the rotating thin spherical shell is derived.Later the formula for the transmission coefficient in the centre of the thin spherical shell is achieved.A computer program for the shielding shell is also offered.A relation of the magnetic field frequency

rotating velocity and transmission coefficient as well as other important shielding properties are found out.
