The dynamics of semiflexible polymers under the influence of shear flow is studied analytically. Power laws are derived for various conformational and dynamical quantities which are in agreement with experimental findings. In particular, the tumbling motion is analyzed and expressions are provided for the probability distributions of the orientation angles and the tumbling time. The calculations explain the similarities in the behavior of flexible and semiflexible polymers as well as free-draining and nondraining systems.
对剪切流作用下半柔性聚合物的动力学进行了分析研究。推导了各种构象和动力学量的幂律，这些幂律与实验结果一致。特别地，分析了翻滚运动，并给出了取向角和翻滚时间的概率分布表达式。计算结果解释了柔性和半柔性聚合物以及自由排水和非排水系统行为的相似性。
