| 摘 要： | 研究了一类二阶变系数中立型时滞微分方程的振动性.在前人研究的基础上,通过引入函数r(t),使方程一般化,进而由构造函数法,可以得到方程(1)和(2)是振动的充分条件.结果推广并丰富了已有文献的结论.

| Abstract: | This paper considers oscillation of the second order neutral delay differential equations with variable coefficient.On the basis of relevant reference,the equations become the general by using of a function r(t),then,we obtain oscillations of the equations(1) and(2) through constructing function.Conclusions of this article extend some conclusions of the references before. |
