According to the retweeting mechanism based on user relations, we introduce the contacted state of an agent, and build a model of information propagation process in social networks. In the model, agents have two absorbing states, that is, the infected and refractory state. Experimental prove that small spreading rete can make information diffuse widely, and the degree based density of infected agents increases with the degree monotonously. The influence between information occurs only when different information originates in the same local neighborhood.
