用非线性非平衡热力学讨论动电效应

DISCUSSION ON THE ELECTROKINETIC EFFECTS BY WAY OF NONLINEAR NON-EQUILIBRIUM THERMODYNAMICS

本文用非线性非平衡热力学讨论了动电效应.首先,解释了实验值与旧理论不符的问题.其次,给出了旧理论处理动电效应的近似条件.最后,提出了一个新看法,在一定条件下,对某种液体和某个膜,当△P、△φ达一定值时,动电效应也可能出现耗散结构.

This paper discusses the electrokinetic effects by way of nonlinear non-equilibrium thermodynamics. First, it explains the inconsistency of the experimental values with the old theory. Second, the paper introduces the approximate conditions, under which the old theory is used to deal with the electrokinetic effects. Last, a new idea is put forward that under certain conditions, so far as some liquid and membrane are concerned, the electrokinetic effects might appear to be of the dissipative structures when △P and △φ reach a certain value.
