摘　　要：该文讨论了 d/dt[x(t)+cx(t-τ)]+P(t)x(t-σ)+f(t)=0,t≥t_0一阶非齐次中立型微分差分方程的振动性.得到了一些方程振动的充分条件,推广了某些齐次方程的振动结果.In this paper oscillation of the first order nonhomogeneous neutral differential differ-ence equationsd/dt[x(t)+cx(t--τ)]+P(t)x(t--σ)+f(t)=0,t≥tois discussed. The author gets some sufficient conditions for the equations to oscillate and gener-alizes the result of oscillation of some homogeneous equations.
