摘　　要：对一类四阶带强迫项的脉冲多时滞微分方程的解的振动性作了研究,给出引理解决了方程的非振动解与其各阶导数的符号关系,得到其振动性的判别准则.The paper focuses on the differential equations with forcing non-oscillatory solutions and the oscillations of a class of fourth-order impulse and multiple delay term. A lemma is given to deal with the sign relation of the derived functions. Some criterions about the oscillation of thesolutions to the equations are obtained.
