摘　　要：考虑一类一阶中立型非线性差分方程 ,在允许P(n) - 1振动的情况下 ,获得了此方程所有解振动的若干充分条件 。A class of first order nonlinear delay neutral difference equation is studied. On the assumption that P(n)^(-1) being oscillatory, sufficient conditions for the oscillation of all solution of the equation. are obtained. These results are illustrated by some example.
