考虑了一类具有震动恢复率和时滞的传染病模型,建立了使模型所有解指数收敛于零向量的一些充分条件,并用数值模拟验证了所得的结论,改进和推广了已有文献的相应结果.

英文摘要：

This paper is concerned with an epidemic model with delays and oscillating recovery rates.Some new sufficient conditions are established to ensure that all solutions of this model converge exponentially to zero vector.Some numerical simulations are carried out to support the theoretical findings.Our results improve and generalize those of the previous studies.
