【Abstract】 This paper discusses the research we have done into the oscillation of the solutions to a neutral type hyperbolic equation under the third boundary condition.We have found that the conditions sufficient to the forced oscillation of solutions can be obtained by means of the averaging technique together with Green’s formula and Jesen Inequation.更多还原
