Abstract: Oscillation criteria for a family of second order nonlinear difference equations was investigated with Riccati inequality and some necessary analysis technique，the author obtained some sufficient conditions when solutions of the equation are oscillatory，which improves some known results. Finally，an example concerning the results was given.

Key words: nonlinear, difference equation, oscillation, positive solution
