摘要: 研究一类流行性传染病的传播动力学生态模型. 首先建立相应模型满足的微分方程; 其次构造一组泛函, 并计算出它们的变分; 然后利用变分原理决定相应的Lagrange参数; 最后利用迭代理论得到原问题解的迭代公式, 从而利用迭代方法求得相应模型的近似解.

Abstract: A class of epidemic contagion is considered. The transmissive dynamic ecological model is described. Firstly, the differential equa tions are established for the corresponding model. Secondly, a series of function is constructed and their variations are calculated out. And via the variational principle the Lagrange parameters are decided. Finally, the iteration formu las for the solution of the original are obtained by means of the iteration theory. Thus the approximate solution of the corresponding model is obtained with the iteration method.

Key words: epidemic contagion, nonlinear, transmissive dynamic model, variational iteration
