  1. The solving steps are as follows : the field is divided into three regions by the cylindrical surface of the finite - length cylinder and the location of the delta - coils. because " the surface current source is placed at the interface, the non - homogenous restricted equation on the magnetic vector potential is transformed into the homogenous helmholtz equation. by using the method of separation of variables to solve equation and according to the interface conditions and the condition at infinity to determine the unknown constants, the expressions for the magnetic vector potential of the three regions are solved out

    在求解過程中,假定放置式柱線圈是由多個對稱環線圈密饒而成,首先求解含有有限長磁芯的通電對稱環線圈的電磁場:以有限長柱磁芯的側面和環線圈所在柱面為分界面將場域劃分為三個區域,由於場源放置在內邊界面上,使得關于矢量磁位的非齊次約束方程轉化成齊次亥姆霍茲方程,利用分離變量法求解,根據分界面鄭州大學碩十研究生畢業論文摘要條件以及限遠條件確定待定常數,從而得到各場區矢量磁位的表達式。
