This is a study of the properties of the interfaces in fluid mixtures at equilibrium, using the methods of thermodynamics and statistical mechanics, with emphasis on those aspects which are important in chemical engineering processes. In a first part, analytical and numerical methods are used to determine the effects of the range of the intermolecular forces on the properties of surface tension. Next, a method of determining the behavior of surface tension in fluid mixtures is developed as a function of temperature, by extrapolation from the critical region, in which so much detailed information has recently become available. Finally, the structure and cohesion of surfactant films occuring in such mixtures as oil and water are studied. Analytical, numerical and possibly, videomicroscopic techniques are used to study this last problem.

这是用热力学和统计力学的方法研究流体混合物在平衡状态下的界面性质，重点是那些在化学工程过程中重要的方面。在第一部分中，使用解析和数值方法来确定分子间作用力范围对表面张力性质的影响。下一步，通过从临界区外推，发展了一种确定流体混合物中表面张力行为的方法，作为温度的函数，在临界区，最近获得了如此多的详细信息。最后，研究了油水混合体系中表面活性剂膜的结构和凝聚力。分析、数值和可能的视频显微镜技术被用来研究最后一个问题。
