通过分析扩散流行病模型来解释流感的传播。采用基于有限差分的算子分裂(OSBFD)、基于无网格法的显式公式(EFBMM)、基于无网格法的算子分裂(OSBMM)来获得稠密种群变化初始分布下方程的数值解。扩散和分布的特定作用在疾病传播中得到了强调。还介绍了如何通过药物和非药物创新来具体减少疾病的传播。还给出了涉及所有平衡稳定性的数值解。 (C) 2020 Elsevier Ltd. 保留所有权利。
The transmission of influenza has been explained by analyzing a diffusive epidemic model. The Operating splitting based on finite difference (OSBFD), explicit formula based on meshless method (EFBMM), Operator splitting based on meshless method (OSBMM) are applied to obtain numerical solutions of equations under varied initial distribution of dense population. The specific role of diffusion and distribution has been accentuated in spread of ailment. It is also presented that how the transmission of disease is specifically reduced by the medicative and non-medicative innovations. The numerical solutions involved in stability of all the equilibria are also stated. (C) 2020 Elsevier Ltd. All rights reserved.
