质心、引力作用中心与感应电荷中心

The Center of Mass,Center of Gravitation and the Center of Inductive Electric Charge

类比质心和引力作用中心,引入感应电荷中心和静电引力作用中心概念.导出点电荷与导体球问题的感应电荷中心在象电荷位置处,阐明感应电荷中心的重要物理意义.

The concept about the center of inductive electric charge and the center of electrostatic force are introduced by analogy with the center of mass and the center of gravitation. The problem of the point charge and conductive sphere is derived that the center of electric charge located in the place of image charge. This essay expounds clearly about the significance of the physical meaning in the center of inductive electric charge.
