Abstract
The nonequilibrium electrical potentials across an artificial membrane bathed by solutions of a single salt have been measured and calculated using the Goldman-Hodgkin-Katz equation and the irreversible thermodynamic equation. The latter equation predicts the observed potential differences over a 2500-fold concentration range, while application of a modified Goldman-Hodgkin-Katz equation leads to difficulties.
摘要
已使用戈德曼-霍奇金-卡茨方程和不可逆热力学方程对浸于单一盐溶液中的人造膜上的非平衡电势进行了测量和计算。后一个方程在2500倍的浓度范围内预测了观测到的电势差，而应用修正的戈德曼-霍奇金-卡茨方程则会导致困难。
