疾病和信息通过社会和信息网络传播。理解网络中的传播现象不仅需要关注度分布，还需要关注度相关性。然而，它被认为是很难分析处理的程度相关性蔓延现象的影响。在这里，我们引入度相关性，用一种简单的方法，并提出了理论公式的爆发阈值和基本再生数。我们从理论上阐明了度相关性的影响。
Disease and information spread over social and information networks. Understanding the spread phenomena in networks requires paying attention not only to the degree distribution but also to the degree correlation. However, it is considered difficult to analytically deal with the effect of degree correlation on spread phenomena. Here, we introduce degree correlation using a simple method and present the theoretical formulas of the outbreak threshold and basic reproduction number. We theoretically clarify the effect of the degree correlation.
