为了研究现实生活中不同个体的易感性、传染性和感染周期不同对流行病传播的影响，提出了一类具有受限感染周期的流行病传播模型。根据复杂网络的基本理论对模型展开分析，得出了传播阈值的表达式，并通过数值模拟进行验证。研究结果表明，带有受限的感染周期比带有相同的感染周期更不利于流行病的传播，不同的易感性及传染性的分布也影响流行病传播。

In order to study the influence on epidemic spreading caused by individuals’different susceptibilities,infectivities and infection periods,an epidemic spreading model with constrained infection periods is proposed.By using the theory of complex network,this paper mainly investigates the epidemic threshold of the proposed model and verifies the theoretical conclusions by numerical simulations.The results show that the constrained infection periods are more repressive to epidem-ic transmission on random mobile network than the same infection periods.Moreover,the different distributions of individu-als’susceptibility and infectivity are also important impacts in epidemic spreading.
