中文摘要：

研究三种意识对疾病传播的影响,建立了无标度网络上的SIS模型,并得到了该模型无病平衡点的稳定性及传播阈值。结果表明局部意识和接触意识可以提高传播率的阈值,全部意识对无病平衡点的稳定性及传播阈值没有影响。最后利用数值模拟验证了理论结果。

英文摘要：

We study the influence of three kinds of awareness on the disease transmission,and establish theSIS model on scale-free network,and obtain the epidemic threshold and stability of the disease-free equilib-rium point. The results show that both local and contact awareness can raise the epidemic thresholds whilethe global awareness cannot. Finally, the numerical results are used to verify the theoretical results.
