摘要：
An apparatus used to study air/water interfacial surface viscoelasticity through longitudinal waves is described. The longitudinal surface waves are generated by an oscillating barrier driven by a small DC motor and detected with a capillary wave. The damping coefficient and the wavenumber of the longitudinal wave are measured simultaneously by using a “double lock-in” technique. Experimental results of interfacial viscoelasticity for C12E6 (hexaethyleneglycol mono n-dodecyl ether) are reported. © 1993 Academic Press, Inc.
