n阶非线性泛函微分方程解的渐近性质

Asymptotic Property of Solution of Differential Eguation for n-fold Nonlinear Functional

文[1]给出了方程(1)的任一个非振动解x(t)当t→∞时收敛到零的充分条件。本文研究表明文[1]的给果可以在更弱的条件下得到证明。并且,另一使方程(1)的非振动解当T→∞时收敛到零的充分条件也被给出。

The paper [1] gived any une nonoscillation solution r（t） of equation （1） is Concierge to zero＇s Sufficient conditiom.as t→∞, In this paper study denote the consequence of paper [1] may be obtained demonstralion at the more weak condition under, and Another one so that the Nonoscilation so- lution of equation （1） converge to zero＇s sufficient condition gired also.as t→∞.
