我们研究了囊泡的动力学与内部和外部之间的粘度对比，并受到线性剪切流。结果表明，当r=eta（in）/eta（out）= r（c）时，囊泡相对于剪切流呈现稳定的取向。翻滚以鞍结分叉的形式发生。我们提出了分析和数值结果。我们开发了一个强大的方法，平流场的方法。这种方法允许人们以极大的灵活性处理几种不同的现象。
We study dynamics of vesicles with a viscosity contrast between the interior and exterior, and subjected to a linear shear flow. It is shown that the vesicle, which assumes a steady orientation with respect to the shear flow for r=eta(in)/eta(out)= r(c). Tumbling occurs as a saddle-node bifurcation. We present analytical and numerical results. We develop a powerful method, the advected-field approach. This method allows one to treat several different phenomena with great flexibility.
