摘　　要：研究了十六烷基三甲基溴化铵和十六烷基三甲基溴化铵/氯化钠复合体系气-液界面的扩张粘弹性质。研究结果表明,十六烷基三甲基溴化铵表面膜的微观弛豫过程主要受扩散弛豫过程控制,十六烷基三甲基溴化铵/氯化钠复合体系的界面扩张粘弹性质参数随氯化钠浓度增加呈一定变化趋势,相角基本上不受氯化钠浓度影响。The interfacial dilational viscoelasticity properties of cetyltrimethyl ammonium bromide and cetyltrimethyl ammonium bromide/ sodium chloride compound system were studied. It was shown that the microscopic relaxation model of the surface film was decided by diffusion relaxation control model. The interfaeial dilational viscoelasticity property parameters of eetyltrimethyl ammonium bromide/ sodium chloride compound system were changed with the change of sodium chloride＇s coneentration. The phase angle was not affected by the concentration of sodium chloride basically.
