Abstract

A change in conductance of an artificial membrane at a threshold concentration of environmental salt solution was interpreted in terms of a change in adsorptive reaction rate on the interface which was derived from an autocatalytic reaction model. The model also accounted for a self-sustained potential oscillation which was observed when the salt concentration of one side of the membrane was higher than the threshold mentioned above and that of the other side lower.

摘要

在环境盐溶液的阈值浓度下，人工膜的电导率变化是根据界面吸附反应速率的变化来解释的，该变化源自自催化反应模型。该模型还解释了一种自持电位振荡现象，当膜一侧的盐浓度高于上述阈值而另一侧的盐浓度低于该阈值时会观察到这种现象。
