研究了油水界面和盐水系统中的振动现象与生物膜兴奋性的关系。在一个水相中含有油酸钠（一种肥皂）的水-油-水液体膜中观察到有节奏的、持续的电振荡。振荡是由油酸阴离子和其他化学物质通过油水界面转移引起的。当盐溶液容器与位于盐溶液下方的纯水容器用窄管或孔连接时，也观察到盐溶液的振荡流动。电势的有节奏的变化，与周期性流动有关，产生了。这些实验系统被认为是非线性振荡器，并使用基于非线性微分方程的理论进行了讨论。
Abstract Oscillatory phenomena in an oil-water interface and in a salt-water system have been studied in relation to excitability in biomembranes. A rhythmic, sustained electrical oscillation was observed for a water-oil-water liquid membrane, containing sodium oleate, a soap, in one of the aqueous phases. Oscillations were induced by the transfer of the oleate anion and other chemicals through the oil-water interface. The oscillatory flow of salt solution was also observed when the vessel of salt solution was connected with a narrow tube or pore to the vessel of pure-water situated below the salt solution. A rhythmic change of the electrical potential, associated with the periodic flow, was generated. These experimental systems are considered as nonlinear oscillators and are discussed using a theory based on nonlinear differential equations.
