In this paper the author sketches out the following points. My unified formulas for reflection and transmission of plane elastic wave; Dynamic difference between converted wave and unconverted wave; The reflection and transmission coefficients of plane elastic and converted wave incident upon an interface between different elastic media are the odd functions of ray parameter p respectively. The reflection and transmission coefficients of unconverted wave are the even function of ray parameter p. Some power series type formulas for reflection and transmission of plane elastic wave, which include Aki's and Shuey's formulas that are widely used nowadays. These new formulas have more definite physical meaning, clearer lithology property, simpler form and easier separation of variates than other's formulas. They broaden the application of AVO technique, favor better lithology parameter inversion and advantage separating P wave from S wave. The author's AVO filtering concept that copes with the problem existing in seismic horizontal stacking. The author's AVO curve filtering, which is a new processing method for obtaining amplitude fidelity, high resolution and high S/N ratio. It is pointed out that traditional CDP stacking concept may be forsaken in more reliable new lithology analysis, which is the development tendency of seismic exploration. The principles and application of these new methods are illustrated at the conclusion of the article.
