Abstract

Studies were made on electrical oscillations across a liquid membrane consisting of an oil layer, nitrobenzene containing picric acid, between two aqueous layers. This system showed sustained rhythmic oscillations of electrical potential of 200-300 mV with intervals in the order of 1 min. It was found that the histogram of frequency of oscillations was characteristic depending on the structures of the sugars. The histograms of glucose, fructose, galactose and sorbose showed a single maximum whereas those of sorbitol and mannitol showed double maxima.

摘要

对由两层水层之间的油层（含苦味酸的硝基苯）构成的液膜上的电振荡进行了研究。该系统显示出200 - 300 mV的持续有节奏的电势振荡，间隔约为1分钟。发现振荡频率的直方图具有特征性，取决于糖的结构。葡萄糖、果糖、半乳糖和山梨糖的直方图显示有一个单一的最大值，而山梨醇和甘露醇的直方图显示有两个最大值。
