| 摘 要： | 导出了包围有接地导体球的带电导体球壳与地组成的静电系统的精确解．证明在该系统中，不管球壳与地之间的距离如何，电行在地面产生的电势与在无限远产生的电势总是相等．指出不精确解会导致无限远与大地的电势不相等的错误结论．

| Abstract: | An exact solution for a electrostatic system formed by the ground and the charged conducting spherical shell surrounding a grounded conducting sphere is give.The equality between potential at infinity and at the ground is proved without regard to the distance between the spherical shell and the ground.Approximate solution for the system may lead to incorrect conclution of unequality between these potenials. |
