许多真实的网络由社区组成：节点组，其中连接密集，但节点之间的连接稀疏。本文基于易感者感染（SI）模型，比较了具有相同程度分布的有和无群落结构的两种无标度网络之间的流行病流行率。研究发现，具有强社区结构的网络有助于降低网络中流行病流行带来的危险，这通过每个时间步的流行规模、流行规模的变异性和新感染节点的平均程度的比较结果得到体现。我们还注意到，当面对具有强大社区结构的网络时，应特别注意靠近初始感染种子的节点。
Many real networks consist of communities: groups of nodes within which connections are dense, but among which connections are sparser. In this paper, based on the susceptible-infected ( SI) model, epidemic prevalence is compared between two kinds of scale-free network, with and without community structure, which have the same degree distribution. It is found that networks with strong community structure are helpful for reducing the danger brought by epidemic prevalence in the network, which is shown by the comparison results of the prevalence scale, the variability of the prevalence scale and the average degree of new infected nodes at each time step. We also note that when facing networks with strong community structure, special attention should be paid to nodes that are close to the initial infected seeds.
