Importance of external conditions and properties of phases creating liquid films, in outcome of the air bubble collisions with liquid/air and liquid/solids interfaces in clean water and in liquid solutions, is critically reviewed. The review is focussed on initial stages of the liquid films formation by bubbles colliding with interfaces, as well as, on analysis of the most important factors responsible for the collision's outcome, that is, either the rapid bubble bouncing or formation of the symmetrical or unsymmetrical liquid films and their thinning to the critical rupture thicknesses. Data on formation of liquid films under dynamic conditions, both in pure liquids and solutions of electrolytes and various surface-active substances, are reviewed and importance of hydrodynamic boundary conditions at interacting interfaces for energy balance in the system is discussed. It is shown that the liquid films stability, which in stagnant systems are directly determined by properties of the liquid/gas and liquid/solid interfaces, can be quite different in dynamic environment. A mechanism of the bubble bouncing from various interfaces in terms of interplay between energy exchange and kinetics of liquid film drainage is analyzed. It is shown that this mechanism is universal and irrelevant on the nature of interacting phases. Moreover, mechanisms responsible for wetting (unsymmetrical) film stability under dynamic conditions are discussed in light of the most recent studies, showing a crucial role of electrolyte, kind and concentration of surface-active substances, electrical surface charge, hydrophilic/hydrophobic properties of solids and presence of air entrapped (nano- and/or micro-bubbles) at surfaces of highly hydrophobic solids in the liquid films rupture.

关于对称和不对称液体膜的形成和稳定性中外部条件和相互作用相性质的重要性。
由于气泡与清洁水和液体溶液中的液体/空气和液体/固体界面的碰撞而导致的外部条件和形成液膜的特性的重要性受到了严格的审查。审查的重点是气泡与界面碰撞形成液体膜的初始阶段，以及对导致碰撞结果的最重要因素的分析，即快速气泡反弹或对称或不对称形成的现象。液膜及其变薄至临界破裂厚度。在动态条件下在纯液体以及电解质和各种表面活性物质溶液中形成液膜的数据，综述了水动力边界条件在相互作用界面上对于系统能量平衡的重要性。结果表明，在动态系统中，在停滞系统中直接由液/气和液/固界面性质决定的液膜稳定性可能会大不相同。从能量交换和液膜排水动力学之间的相互作用出发，分析了气泡从各种界面弹跳的机理。结果表明，该机制是通用的，与相互作用阶段的性质无关。此外，根据最近的研究，还讨论了在动态条件下润湿（非对称）薄膜稳定性的机制，这些研究表明电解质，表面活性物质的种类和浓度具有至关重要的作用，
