We subdivide social network user’s state to four kinds, Unknown state, Known state, Informed state,refractorystate.Different users may have different judgment for th same information, they transmit the information to their friends in social network lie on the information value and compare with the information threshold, we think unknown users in social network have different thresholds of an information value and sub divide these users to i class, and assume accumulated information valueof users follow uniform distribution. Apply mean field theory to build the diffusion model,from the number of refractory nodes, we can know the diffusion effect of an information in asocial network.
