%X Some new oscillation and nonoscillation criteria for second order nonlinear neutral delay differential equations are established. Illustrative examples are given. Our theorems improve and generalize several known results.
%K Positive and negative coefficient
%K second order neutral equation
%K oscillation
%K nonoscillation<br>正负系数
%K 二阶中立型微分方程
%K 振动
%K 非振动
