摘要：

The electrical conductivity and ion permeation in planar lipid membranes, separating bath solutions of different potassium chloride concentrations in the range of 0.1-1 moll-1, were measured using a patch-clamp pipette technique. The results are discussed in terms of a channel conduction model based on the statistical rate theory. These results indicate that the ionic transport process in these systems can be described as a first-order chemical reaction with appropriate values of the equilibrium exchange rate constant and partition coefficients.
