摘要: 对无限大导体表面,楔形导体表面,半圆柱形凸起表面电荷面密度进行了具体的计算,结果表明在静电平衡的条件下导体表面虽曲率相同,但表面电荷面密度却可以不同.

关键词: 曲率, 电荷面密度, 电势, 无限大导体, 楔形金属导体, 半圆柱形凸起

Abstract: The surface charge density of the infinite conductor and wedge-shaped conductor as well as the gibbous surface of the half-columniform conductor is calculated in detail. It is found that the surface charge density of the same curvature radius conductors might be different in static balance state.

Key words: curvature radius, surface charge density, potential, infinite conductor, wedge-shaped conductor, gibbous surface of the half-columniform conductor
