【摘要】 <正> 本文研究的体系是在一个U 形玻璃管里,底部加入苦氨酸的硝基苯溶液（油相）作为人造液膜,右边支管中加入含乙醇的十八烷基三甲基氯化铵的水溶液,左边支管中加入蔗糖水溶液（或去离子水）.电势振荡振幅在20—150mV 之间.根据文献报导,表面活性剂穿过油相产生界面振荡.本实验用的十八烷基三甲基氯化铵(简称C₁₈⁺Cl^-)是一个阳离子型表面活性剂,与苦氨酸（简称HA）接触时显橙红色,更多还原

【Abstract】 An artificial membrane consisting of pricramic acid in nitrobenzene was used asan oil phase imposed between two aqueous phases.The right one contained trimethyl-slearylammonium chloride and aicohol;and the left contained sucrose solution（orH₂O）.We found that this system exhibited rhythmic oscillation of electrical potential.The amplitude of the oscillations was between 20—150mV.The oscillations were ob-served even when ethyl alcohol was absent in the aqueous of trimethylslearylammoniumChloride,and the increase in amplitude of oscillations with time was found to be lessin the presence of sucrose.Some of the expremental results have been explained.更多还原
