摘要
讨论了一类非线性项具时滞的二阶中立型微分方程的振动性,得到了所研究方程振动的三个充分条件.所得结论推广了已有的相应结论.
This paper dicusses the oscillation of one kind of second-order nonlinear neutral delay differential equation. Three sufficient conditions in all solutions of the equation oscillate is obtained. The conclusions which we draw generalize the former conclusions.
