摘      要：A new method is used to obtain the anomalous dimension in the solution of the nonlinear diffusion *** result is the same as that in the renormalization group (RG) *** gives us an insight into the anomalous dimension in the solution of the nonlinear diffusion equation in the RG *** on this discussion,we can see anomalous dimension appears naturally in this system.
