%X In this paper, by the use of the order methods in nonlinear analysis and the thed point theorems of increasing operators,the asymptotic properties of positive solutions of n-th order nonlinear neutral functional differential equations are classified in detail, some sufficient conditions, necessary and sufficient conditions and several examples of the existence of positive solutions of n-th order nonlinear neutral functional differential equations are given.The results obtained include the main results in 4] and 5],and the method of proof is different from those in 4] and 5].
