我们通过应用非标准有限差分格式推导了具有时滞的离散 SIRS 流行病模型。通过改进离散化和应用连续流行病模型的证明，获得了解决方案全局动态的充分条件。我们的离散模型的这些条件与原始连续模型的条件相同。 (C) 2010 Elsevier Inc. 保留所有权利。
We derive a discretized SIRS epidemic model with time delay by applying a nonstandard finite difference scheme. Sufficient conditions for the global dynamics of the solution are obtained by improvements in discretization and applying proofs for continuous epidemic models. These conditions for our discretized model are the same as for the original continuous model. (C) 2010 Elsevier Inc. All rights reserved.
