In this parer, the properities of the disordered superlattice was simulated by the disordered layer system. The dynamic density response function X(q, ω) was obtained with B+S equa-tion in the weak disorder limit. And the localization lengthes, the parallel and transverse conductivities were found through X(q, ω). We derived the self-consistent equation of the cif-fusion coefficients Dk(ω) which depend on the frequency ω. The results were discussed.
