| Abstract: | The authors discuss a class of second order nonlinear differential equations.By using the generalized Riccati transformation and the integral averaging technique,new osciallation criteria are obtained for all solutions of the equations to be oscilltory.Our results generalized and extend some known oscillation criteria in the literature. |

| Keywords: | second order nonlinear differential equations damping term oscillation |
