To explore the spread of rumors in social network, based on the principles of coupling network, the model of RD-IHSAT was established on Barabási-Albert (BA) scale free network and Watts-Strogatz (WS) small world network.The classic model of SIR was optimized, by combining it with three concerns, the interest decay, the social consensus and the spiral of silence effect, and adding four roles, hesitated, adherent, reticent and debunker.Results of numerical simulations are as follows: an information outbreak can be triggered by coupling network, not only the spreading speed but the scale as well; the dissemination can be markedly suppressed when the probability of rumor-refuting for the hesitated and spreaders arises; the chances of transition from spreaders to adherents drop; increasing the proportion of silent groups is a key part of curbing the spread of rumors; the control of the time lag in refuting rumors will greatly affect the effect of refuting rumors.

Key words: rumor dissemination, coupling network, interest decay, social consensus, spiral of silence, model of RD-IHSAT
