中文摘要：

研究一类非线性脉冲时滞双曲型方程组在Robin以及Dirichlet边界条件下的振动性质.利用广义的Riccati变换、平均值方法及不等式技巧,获得了方程组在两类边界条件下振动的充分条件,并给出了应用实例用以检验结论的有效性.

英文摘要：

Oscillatory properties of systems of neutral type impulsive hyperbolic equations with several deviating arguments under the ＇Robin boundary condition and the Dirichlet boundary condition are investigated, and several new sufficient conditions for oscillation are presented. The main resuits are illustrated by one example.
