Then, at the foundation of the model of SIR for there has been up, we build up a model of SCIR that includes the factor of network infrastructure such asnetworm congest and delay. and compare the model of SCIR between the model of SIR.

• 然后，在已有的SIR模型的基础上，建立一个包含了网络延迟因素的SCIR模型，并比较了SCIR模型相对于SIR模型的优点。
