Experimental results on mean inclination angle and its fluctuation due to thermal noise in tank-treading motion of a vesicle in shear flow as a function of vesicle excess area, normalized shear rate, viscosity, and viscosity contrast between inner and outer fluids, , are presented. Good quantitative agreement with theory made for was found. At the dependence is altered significantly. Dependence of the vesicle shape on shear rate is consistent with theory. A tank-treading velocity of the vesicle membrane is found to be a periodic function close to that predicted by theory.
本文给出了关于囊泡在剪切流中坦克履带式运动时平均倾斜角及其因热噪声引起的波动的实验结果，这些结果是囊泡过剩面积、归一化剪切速率、粘度以及内外流体粘度对比的函数。发现实验结果与理论预测具有良好的定量一致性。在某一条件下，这种依赖关系发生了显著变化。囊泡形状对剪切速率的依赖性与理论一致。发现囊泡膜的坦克履带式运动速度是一个接近理论预测的周期函数。
