We consider two parallel planar charged surfaces bearing unequal surface charge densities interacting across a region in ionic equilibrium with a neutral salt solution. Combining rules are derived appropriate for interactions across distances of separation greater than the characteristic Debye length. When ions are excluded from the regions behind the interacting surfaces there can be repulsion between charged surfaces of opposite sign; but surfaces bearing charges of the same sign never attract one another. Also, surfaces bearing electrostatic potential of like sign can attract.
我们考虑两个平行的平面带电表面，它们带有不相等的表面电荷密度，在与中性盐溶液处于离子平衡的区域中相互作用。推导了适用于相隔距离大于特征德拜长度时相互作用的组合规则。当离子被排除在相互作用表面后面的区域时，带相反电荷的表面之间可能存在排斥力；但带相同电荷的表面从不相互吸引。此外，带相同符号静电势的表面可以相互吸引。
