摘要：

Random walks in a d-dimensional stochastic environment with a static structure factor S(q)-const and S(q) approximately q-2, respectively, are analyzed by renormalization group techniques. In dependence on the strength of the disorder normal, anomalous or limited diffusion (finite diffusion radius) for t-->infinity was detected.
