摘要
研究二阶泛函微分方程χ＂（ι）－Ρ（ι）ｆ（χ（τ（ι）））ｇ（χ‘（σ（ι）））＝０解的渐近性与振动性．给出了有界解振动的充分条件．
it is discussed that the oscillatory and the asymptotic behavior for the following second order functional differential equation X'(ι) -p(ι)f(χ(τ(ι)))g(χ '(ο(ι))) = 0The sufficient condition for the oscillation of the bounded solution are given.
