摘　　要：通过对传统SEIR模型进行扩展和修正,建立了一个适合模拟电子邮件(E-mail)病毒在网络系统内扩散的E-SEIR模型,并以此为基础研究了E-mail用户的邮件信息处理行为和反病毒技术支持等关键因素对E-mail病毒扩散的影响。从实验结果看,E-SEIR模型能够很好模拟E-mail病毒在网络系统中的扩散过程,同时也可用于E-mail信息网络中环境参数和某些病毒控制策略的模拟和评价。By extending the traditional SEIR model, an E-SEIR model is designed, which is more suitable for the simulation of E-mail- based virus propagation in limited system. With E-SEIR some factors are simulated, such as mail checking time, technique supporting, immunization and so on. The fruitful simulation results show that E-SEIR not only could simulate perfectly the propagation mode of E- mail virus in limited system, but also could be used in anti-virus policies simulation and evaluation.
