摘要
本文简要介绍了一种研究泡沫液膜性质的新方法──用动态力学方法测定自由液膜的动态拉伸粘弹性。根据动态力学方法的基本原理及本实验室研制的测定近似圆柱状自由液膜动态拉伸粘弹性的装置，在不同的拉伸频率下对十二烷基硫酸钠水溶液所形成的液膜的测定结果表明，其贮能模量（拉伸弹性）和耗能模量的测定重现性都相当好，相对误差不超过±５％。
An attempt is made to introduce a dynamic mechanical method applied to studying viscoelastic matericals by measuring the dynamic extensional viscoelasticity of foam's liquid films. The principle and the equipment are described simply. The liquid films are cylindroid in configUration approximatly. The result of solutions of sodium dodecyl sulphate under different extensional frequencies show that both storage modulus and the loss modulus obtained are repeatable. Their relative errors are less than five Percent.
