Abstract:
We find that there are two time scales t and c In t in the asymptotic behaviour of diffusion process in the porous medium, which give us a new insight to the anomalous dimension in this problem, further we construct an iterative method to calculate the anomalous dimension and obtain an improved result,[著者文摘]
