摘要
本文研究了具有非线性接触率βＩｐＳ１＋αＩｐ和恢复类中具有分布时滞的ＳＩＲＳ传染病模型的解的存在性和连续性、正不变集、平衡位置以及平衡位置的稳定性。
The paper deals with a SIRS epidemiological model with nonlinear incidence rate βI pS1+αI p and distributional delay in removed class. The existence and continuity of solutions, the positive invariant set, the equilibrium and the stability of the equilibrium for the model are discussed.
