摘要
利用载流圆柱螺旋线系统内部的磁标势满足的Ｌａｐｌａｃｅ方程，以及系统磁矢势的积分形式，定出Ｌａｐｌａｃｅ方程通解的未知系数，求得左（右）旋单绕圆柱螺旋线的磁标势。应用磁场的叠加原理以及积分法，给出了各种类型如双绕、双双绕、交叉绕等螺旋形Ｗｉｇｇｌｅｒ的场形分布公式。
The general solution of scalar magnetic potential at any interior point of a cylindrical helix wiggler was attained and the expression of magnetic field on axis was also given by solving Lapace's equation. The magnetic field distributions of several kinds of helical wiggler were derived from combination and superposition of the magnetic field, such as right-handed bifilar helix wiggler, left handed fifilar helix wiggler, crossed double helix wiggler, auto guide field wiggler, multiwound wiggler and asymmetric wound wiggler and so on.
