The systems producing non-linear spontaneous oscillations of the interfacial tension and electric potential are considered and the available criteria for development of convective instability by the surfactant transfer through a liquid interface are discussed. The non-linear oscillations are observed by the surfactant transfer from a point-like source situated in the bulk of liquid, by the transfer of two ionic solutes through a liquid interface in two opposite directions, and by the transfer of ionic solutes through a liquid membrane. All these systems are governed by more complicated mechanisms than merely arising oscillatory convective instability. The main experimental results obtained for these three systems as well as theoretical models proposed for their explanation are discussed.
研究了产生界面张力和电势非线性自发振荡的系统，并讨论了通过液体界面的表面活性剂转移导致对流不稳定性发展的现有判据。通过位于液体主体中的点状源的表面活性剂转移、两种离子溶质在两个相反方向通过液体界面的转移以及离子溶质通过液膜的转移来观察非线性振荡。所有这些系统都由比仅仅产生振荡对流不稳定性更复杂的机制所支配。讨论了这三个系统获得的主要实验结果以及为解释它们而提出的理论模型。
