摘要 提出具有加权传播率和非线性传染能力的SIR模型和SIS模型,通过平均场方法证明了这两个模型在加权无标度网络中可以存在非零的传播阈值,从而传播率需要跨越更大的传播阈值才能流行.并且得到的结果在特殊情况下可退化为已有的一些经典结论. In this paper,We introduce SIR model and SIS model with nonlinear infectivity and weighted transmission rate.Using the mean field theory,we prove that there would exit a non-zero epidemic threshold for the above epidemic models,therefore a disease can spread only when the spreading rate goes beyond the larger epidemic threshold.Furthermore some classical conclusions can be derived from our results.
