摘要: 用保角变换方法,将导体圆柱外区域映射为单位圆内区域,线电荷位置映射为单位圆圆心,从而直接写出导体圆柱外电势,并对结果进行详细讨论,还利用软件画出等势线簇图形.

关键词: 保角变换, 静电势, 等势线

Abstract: Conformal mapping is used to simplify the boundary condition, so the electrical potential outside the conductor cylinder can be easily written. The result is also discussed detailedly and the equipotential line maps are plotted by the mathematical software.

Key words: conformal mapping, static electric potential, equipotential line
