我们提出了一个热动力学描述的粘弹性介质中的非马尔可夫扩散方程的记忆功能的单粒子和集群的异常扩散。这些功能的标度行为进行了分析，考虑流体力学和集群大小的空间随机游走参数。我们解释的实验结果扩散的布朗粒子在细胞骨架中，在簇-簇聚集，并在悬浮液中的胶束。
We present a thermokinetic description of anomalous diffusion of single particles and clusters in a viscoelastic medium in terms of a non-Markovian diffusion equation involving memory functions. The scaling behavior of these functions is analyzed by considering hydrodynamics and cluster-size space random walk arguments. We explain experimental results on diffusion of Brownian particles in the cytoskeleton, in cluster-cluster aggregation, and in a suspension of micelles.
