摘要
从Tween80水溶液的动态表面张力计算出动态吸附量，发现动态表面状态方程的适用性与溶液浓度有关。对于小于临界胶柬浓度的Tween80水溶液，浓度位于0．0107～0．0938mol m^-3的较大范围内，动态吸附量T1遵从由Szyszkowski吸附等温式导出的动态表面状态方程，低于0．0055mol m^-3时，实验测定的动态吸附量与各动态表面状态方程的计算值均不符。
The dynamic adsorption Gt was estimated from dynamic surface tension for aqueous Tween. 80 solutions at 30℃. The various surface state equations were filled with these data of Gt . It is found that the validity of surface state equations was concentration dependent. The dynamic adsorption Gt obeys the dynamic surface state equation obtained from the Szyszkowski adsorption isotherm over the range of Tween 80 concentration from 0. 0107 to 0. 0938 mol m^-3（below its critical micelle concentration civic）. When concentrations lower than 0. 0055 tool m^-3, the dynamic adsorption Gt observed from experiment does not agree with those calculated from the different surface state equations.
