建立了一类带有脉冲接种和饱和传染率的类年龄结构SEIR流行病模型，讨论了系统无病周期解存在的条件，给出了染病再生数的表达式，证明了染病再生数小于1时，无病周期解是全局吸引的。
建立瞭一類帶有脈遲接種和飽和傳染率的類年齡結構SEIR流行病模型，討論瞭繫統無病週期解存在的條件，給齣瞭染病再生數的錶達式，證明瞭染病再生數小于1時，無病週期解是全跼吸引的。

A class age-structured SEIR epidemic model with impulsive vaccination and saturation infectious rate was formulated .The existence of disease-free periodic solution was discussed and the expression of infective reproduc-tive number was obtained .It was proved that the disease-free periodic solution was globally attractive if the infective re-productive number is less than one .
