中文摘要：

经研究,现实的人际网络与无标度网络是很相似的,而传统的SIS模型是建立在均匀网络上的,已经不能满足现在情况.由于无标度网络的复杂性,建立新的模型是非常困难的,所以本文利用计算机模拟的方式来研究无标度网络中的SIS模型.得到了在无标度网络下,传染病传播是很容易的结论.

英文摘要：

The interpersonal relationship is scale -free networks.So, the classic SIS model which is crea-ted in uniform networks is useless , because the scale-free networks are complex .The SIS model in scale-free networks by computer simulation was studied in this paper .The result shows that it is easy to spread to infective diseases in scale-free networks .
