Abstract: Abstract: Some oscillation and non-oscillation criteria for quasi-linear second order equations are obtained. These results are extensions of earlier results of C.Huang(J.Math Anal. Appl.210(1997), 712-723), A. Elbert(J.Math.Anal.Apll.226(1998), 207-219) and J.Wong(J.Math.Anal.Apll.291(2004), 180-188) which are all about oscillation and non-oscillation criteria of the solution of the second order linear equation. After the proof of the main theorem, two examples are given as the additional remarks of the criteria. At last a special case is discussed. And the uniqueness and periodic criteria of the special case are obtained further by using comparison theorem and Leray-Schauder degree approach.
