二阶脉冲时滞微分方程的振动性

Oscillatory Solution to the Second Order Nonlinear Delay Differential Equation with Impulses

文章对二阶脉冲时滞微分方程的振动性作了研究,利用方程中导数符号之间的关系得到了方程的几个新的振动准则,并通过例子验证,说明文中得出的结果改进了已有文献中出现的结果.

Some new oscillatory rules of the oscillatory solution to the second order nonlinear differential equation with impulse are obtained by the connection of derivative appeared in the equation.Some examples are given and showed that our results improve the conclusions obstained in the literature.
