This review presents a summary of the results in the domain of microscopic liquid film hydrodynamics for several decades of experimental and theoretical research. It mainly focuses on the validation, application and further development of the Stefan-Reynolds theory on the liquid drainage, based on the accumulated knowledge of surface forces, surface tension caused by the surfactant adsorption, and diffusion of surfactants. Liquid films are of primary significance for colloidal disperse systems, and diverse industrial processes. The transient stability of the froth phase and the froth drainage is a function of the drainage and rupture of liquid films between air bubbles. In flotation, the bubble-particle attachment is controlled by the thinning and rupture of the intervening liquid film between an air bubble and a mineral particle. Both the experimental and theoretical results are mostly related to the foam liquid films between two bubbles, but can be principally generalized for emulsion films, formed in another liquid, as well as wetting films between a bubble and a solid surface.
这篇综述总结了几十年来关于微观液膜流体动力学的实验和理论研究成果。它主要关注基于表面力、表面张力由表面活性剂吸附引起以及表面活性剂扩散知识的 Stefan-Reynolds 理论对液体排水的验证、应用和进一步发展。液膜对于胶体分散体系和各种工业过程具有重要意义。泡沫相的瞬态稳定性和泡沫排水是气泡之间液膜排水和破裂的函数。在浮选过程中，气泡-颗粒的附着受气泡和矿物颗粒之间的中间液膜变薄和破裂的控制。实验和理论结果主要与两个气泡之间的泡沫液膜有关，但可以主要推广到乳化液膜（在另一种液体中形成）以及气泡和固体表面之间的润湿膜。
