摘　　要：本文通过引入参数函数,结合完全平方术,研究了一类二阶非线性中立型泛函微分方程解的振动性,所得结果推广了已有文献的部分结果.By introducing parametric function and integral square, a class of second order nonlinear neutral differential equations is considered, oscillatory criterias of the equations are obtained. Some of the known result in the literatures are extended.
