注意到无间隙磁路的三维静磁场计算受到离散化的强烈影响，作者利用基于表面磁化电流法的边界积分方程对铁环面进行了分析。计算误差的主要原因是由于包含一个奇异点的解析积分区域的大小不合适，导致边界积分方程中无磁项的消去不完全。提出了一种减小计算误差的方法，并验证了该方法的有效性。>
Noting that 3-D magnetostatic field calculations for gapless magnetic circuits are strongly affected by the discretization, the author analyzes this effect for an iron torus using a boundary integral equation based on the surface magnetization current method. The main cause of computational error is the imperfect cancellation of the permeability-free terms in the boundary integral equation due to the improper size of the analytical integration region containing a singular point. A method of reducing the computational error is presented and verified to be valid. >
