[Purposes]The objective is to study oscillation of even order half-linear neutral functional differential equation with continuous distributed delay arguments and damping terms.[Methods]Oscillation of even order p-Laplace neutral functional differential equations with damping terms is investigated by using of Riccati transformation,H(t)function,Yang inequality and the integral averaging technique.[Findings]Some new sufficient conditions are established for oscillation of all solutions of the equation,which generalize and improve some known results....
