现行的电磁学对线电荷的能量公式、静电平衡条件都没有直接推导过。
So far both the formula for energy of line charge and the condition of electrostatic equilibrium have not been directly derived from the current electromagnetism.
本文在静电平衡条件的基础上，应用高斯定理讨论带电导体表面的电场强度。
In this paper, Guass theorem is mainly used to discuss the electric field intensity on the surface of charged conductor on condition of electrostatic equilibrium.
静电平衡条件下，孤立带电导体表面任意一点的电荷处于其它电荷激发的电场中，因此受到其它电场斥力的作用，此力即为文章所讨论的表面张力。
In electrostatic field, the charges on the isolated conductor surface are repelled by the other charges, which is defined as surface repulsive force discussed in this paper.
