摘　　要：考虑非线性延迟微分方程的边值方法,在Lipschitz条件下,分析了边值方法的收敛性、全局收缩性和弱全局收缩性。最后,通过数值算例验证了主要结论。The boundary value methods are applied to the nonlinear delay differential equations. Under the assumptions of Lipschitz conditions, the convergence and the global contractivity, the weakly global contractivity of the boundary value methods are analyzed. Finally, some numerical experiments are carried out to illustrate the theoretical results.
