摘要
研究了一类中立型时滞微分方程解的性质，在给定的一些条件之下，得到了方程的所有解是振动的充分条件，同时也讨论了非振动解的渐近性，所得的结论推广并改进了已知的一些结果。
Propersty of solutions for a class of neutral delay differential equations are studied. Some sufficient conditions for all solutions of equation to be oscillatory are obtained and the asymptotic behavior of nonoscillatory solutions of equations are discussed under some conditions. The conclusions we have got here improve and generalize some known results.
