考虑了HIV感染系统中免疫细胞对感染细胞的周期裂解作用，建立起具有免疫饱和效应的时滞微分方程模型，运用非线性泛函分析中的拓扑度理论，得到了系统存在正周期解的充分条件．

Periodically lytic immune response is considered for a class of HIV models with saturation effects and delay which are described as differential equations. By theory of topologic degree in nonlinear functional analysis, sufficient conditions are obtained for the existence of po...
