摘　　要：我们给出一类强迫高阶非线性中立型时滞微分方程一切解振动的充分条件.而且,也研究了一类强迫一阶中立型方程非振动解的渐近性.Sufficient conditions are obtained for oscillation of all solutions of a class of forced higher order nonlinear neutral delay differential equations. Also, asymptotic behavior of nonoscillatory solutions of a class of forced first order neutral equations is studied.

关 键 词：中立型 振动性 渐近性 强迫方程
