摘　　要：表面张力是表征溶液性质的重要物理参数,添加不同类型的表面活性剂,降低表面张力的状态也会不同,其中,动态表面张力的测定能表征表面活性剂分子在溶液内部及表面的运动特性,通过测定动态表面张力,既能表征溶液表面张力降低速率的快慢,也能体现表面活性剂分子在气-液两相吸附的差异。介绍动态表面张力的常用测定方法,归纳各种测定方法的适用范围,综述国内外动态表面张力测定在各领域的应用研究成果及价值。Surface tension is an important physical parameter that characterizes the properties of a solution.The of reducing surface tension varies with the addition of different types of surfactants.Among them,the measurement of dynamic surface tension can characterize the motion characteristics of surfactant molecules inside and on the surface of the solution.By measuring dynamic surface tension,the speed at which the surface tension of the solution decreases can be characterized,It can also reflect the differences in the adsorption of surfactant molecules in the gas-liquid phase.Introduce the commonly used methods for measuring dynamic surface tension,summarize the applicability of various measurement methods,and summarize the application research results and value of dynamic surface tension measurement in various fields at home and abroad.
