The experimental data on the surface rheological characteristics of dodecyl dimethyl phosphine oxide solutions obtained in a fully automatic oscillating bubble device under microgravity conditions in the frequency range 0.01-100 Hz are presented. The complex surface elasticity modulus is obtained form the amplitude- and phase-frequency characteristics of established pressure oscillations in a closed cell without calibration experiments by direct calculation of the necessary coefficients. The characteristics of the adsorption layers obtained from the elasticity modulus are in good agreement with adsorption isotherms and equations of state accounting for the intrinsic (2D) monolayer compressibility.
本文展示了在微重力条件下，于全自动振荡气泡装置中获得的十二烷基二甲基氧化膦溶液在0.01 - 100 Hz频率范围内的表面流变特性实验数据。通过直接计算必要系数，在无需校准实验的情况下，从封闭腔室内既定压力振荡的振幅 - 频率特性和相位 - 频率特性中获得复表面弹性模量。由弹性模量得出的吸附层特性与吸附等温线以及考虑本征（二维）单层可压缩性的状态方程高度吻合。
