摘要
建立了非线性二阶泛函微分方程［ｐ（ｔ，ｘ（ｔ））ｘ’（ｔ）］’＋（ｔ）’＋ｆ（ｔ，ｘ（ｔ），ｘ（ｇ（ｔ）），ｘ’（ｈ（ｔ）））＝０的若干振动准则，这些准则改进。
in the present paper several oscillation criteria for the nonlinear functional differential equations of second order of the form be(t, x(t)), x'(t)]' + f(t, x(t), x(g(t)), X'(t), X'(h(t))) =0 are established. The results obtained improve, generalize and unify some theorems in the literature [1-8].
