摘要：

A newly designed apparatus based on the principle of maximum bubble pressure can be used for measuring the dynamic surface tension in a time interval from 1 ms to 10 s. The surface tension values for pure liquids obtained at small lifetimes are influenced by hydrodynamic effects. These effects depend on the viscosity of the liquid and the diameter of the capillary and decrease with increasing lifetimes. A procedure for correction is proposed and compared with experimental data for water-glycerine mixtures at different compositions and temperatures. Measurements of sodium tetradecyl sulphate in highly viscous water-glycerine mixtures lead to unexpected adsorption behaviour.
