Research on Epidemic Critical Threshold of Risk of Correctional SIS Virus Style

摘要：

Some nodes which have innate immunity have not been considered by the dynamic equation of traditional SIS type. This paper corrected the dynamic equation of risks spreading in the SIS type, and studied epidemic critical threshold of crisis when the risks of corrected SIS type spread in the uniformity network and non-uniform network. In the end, a conclusion could be drawn that if the rate of congenital immunity is bigger, then epidemic critical threshold is bigger, and the risk is more difficult to travel in the network, so the crisis is more difficult to break out. This conclusion is more objective than the conclusions drawn by the scholars in the past.
