讨论了半刚性链的稀解和半稀解的动力学。该结果可用于分析最近在肌动蛋白丝溶液中的光散射实验，其中发现了动态结构因子的异常缩放。这种异常尺度被解释为由于特征长度尺度平行和垂直于灯丝的各向异性尺度，并导致系统尺度中的特征频率为q8/3 log(q)。
We discuss the dynamics of dilute and semidilute solutions of semirigid chains. The results can be applied to analyze recent light scattering experiments from solutions of actin filaments where an anomalous scaling of the dynamic structure factor was found. This anomalous scaling is explained as being due to anisotropic scaling of characteristic length scales parallel and perpendicular to a filament and leads to characteristic frequencies in the system scaling as q8/3 log(q).
