| Abstract: | Starting from the asymptotic behavior of solution,all non-trivial solutions of the second order nonlinear difference equations are divided,in this paper,into four classes which are mutually disjointed.The oscillation nature of a class of extensive second order nonlinear difference equation is discussed by means of the classifying method and analyzing method,Two new oscillation theorems are obtained and the known results in the literature are extended and improved. |

| Keywords: | second order nonlinear difference equation oscillation |
