摘要：
In this paper, the diffusion equations under square and cubic nonlinearities without stochastic homogeneity are solved using the homotopy perturbation method (HPM). The solution average is computed up to fourth order approximation while the covariance is computed up to second order approximation only. The method of analysis is illustrated through case studies and figures.
