英文摘要：

In this paper,the oscillation criteria are established for a forced second order mixed nonlinearities elliptic partial differential equation with damping.In contrast to the existing results in the literature,our results include and improve some recent oscillation criteria for second order forced ordinary differential equations and certain second order superlinear elliptic differential equations.
