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.

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。

Role of the cavity field, the electrostatic repulsive force at the domain boundary and self-enhanced diffraction light induced by physical imperfection on laser-induced surface damage are discussed.

本文讨论了由晶体缺陷所致的自增强衍射光，富集于缺陷的空间电荷所致的空洞场，以及由此场导致的发生在畴界上的静电斥力对此损伤所起的作用。
