摘　　要：应用轴对称情形下Laplace方程在球坐标系中的通解,根据边值关系,求出了在均匀外场中介质球壳各区域的势函数,讨论了场分布特点,并由此得到了介质球壳的磁屏蔽效果.Under the condition of the symmetry of applied axial, the general solution of Laplace equation is obtained in spherical coordinates. According to the relationship of boundary values, the potential function at each zone of medium spherical shell in uniform external field is solved. A discussion on the characteristics of field dis- tribution with the result of magnetic screening effect of medium spherical shell is also given.
