| 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. |

| Keywords: | curvature radius surface charge density potential infinite conductor wedge-shaped conductor gibbous surface of the half-columniform conductor |
