摘要：

The relaxation phenomenon of the surface elasticity was investigated for a soluble mono-molecular layer of sodium dodecyl sulfate (SDS) on aqueous solution. Two kinds of experiments, induced surface wave measurement and ripplon light scattering, were performed at frequencies of 1 kHz and 40 kHz, respectively. In the dilute region below the critical micellar concentration (CMC), the concentration dependence df the surface elasticity obtained at 1 kHz is well explained by the theory of diffusion-dominated relaxation, while the surface elasticity at 40 kHz was found to exceed the low-frequency value, which suggests another relaxation mechanism. The results obtained above the CMC were also presented.
