Using the Taylors formula and Matrix theory, the expression of the second threshold of infection strength is obtained. Furthermore, by comparing the numerical simulations and stochastic simulations it can be found that the dissemination of information inhibits the epidemic spreading, and the alertness of recovery increases the second epidemic threshold of infection strength, also effectively reduces the infection size %K 重叠网络 %K 信息传播 %K 传染强度 %K SAIS模型 %K 阈值 %K < %K br> %K overlay network %K infection strength %K information dissemination %K threshold %K SAIS model %U http://lxbwk.njournal.sdu.edu.cn/CN/Y2016/V51/I11/107
