表现出不连续的电动现象用粘滑转变来描述。磁通力方程是部分线性的，在线性区域，系数满足Onsager倒易关系。通过对离子交换膜的现有数据的解释，我们发现滑移长度与表面电势呈线性关系。我们的结论是，滑移为电动现象中常见的所谓反常表面传导现象提供了另一种解释。这将意味着纳米孔中电动效应的增强。(C)2006爱思唯尔B.V.保留所有权利。
Electrokinetic phenomena exhibiting discontinuities are described in terms of a stick-slip transition. The flux-force equations are partially linear and in the linear regimes the coefficients satisfy Onsager's reciprocal relations. From an interpretation of existing data on ion exchange membranes we find a linear dependence of the slip length with the surface potential. We conclude that slippage offers an alternative explanation for the so-called anomalous surface conduction, as often found in electrokinetic phenomena. This would imply an enhancement of electrokinetic effects in nanopores. (c) 2006 Elsevier B.V. All rights reserved.
