中文摘要：

主要考虑了一类捕食者具有阶段结构和幼年病的生态-流行病SIS模型.通过分析得到了地方病平衡点存在的阈值,以及无病平衡点和地方病平衡点局部渐近稳定和全局渐近稳定的充分条件.

英文摘要：

An eco-epidemiological SIS model with stage and disease in the predator is investigated. The threshold is founded which the epidemic will become endemic or die out.For locally asymptotical stability and globally asymptotical stability of disease-free equilibrium and the endemic equilibrium sufficient conditions are obtained for this model.
