摘　　要：给出三阶线性脉冲微分方程非振动解与其各阶导数的符号关系,得到2个新的判别该方程振动性与渐近性的准则,并用实例来验证其有效性.新准则改进了一些已知结果.According to derivative appeared in asymptotically tending to the the zero connection of nonoscillatory solutions equation, two new oscillatory con of solutions are obtained and verified dit and their deno ons for oscilla by some examples new oscillatory conditons,some previous results are improved.

关 键 词：微分方程 脉冲 振动性 渐近性
