利用一类二阶脉冲滞后型微分方程的非振动解与其导数的符号关系，得到了振动的判别准则，并举例说明了准则的有效性。
利用一類二階脈遲滯後型微分方程的非振動解與其導數的符號關繫，得到瞭振動的判彆準則，併舉例說明瞭準則的有效性。

The sign relation of the non-oscillatory solutions and their derived functions is used, which is belong to a class of second order impulses delay differential equations. Some criterions for discrimination of the oscillations of the solutions of the equations were obtained. Finally one example was given to demonstrate the effectiveness of the criterions.
