Abstract: This paper is mainly concerned with the properties of the characteristics to the Conservation Laws Equation. Considering the relationship between a potential function`s minimum points and the points on the characteristics. Then the characteristics are divided into two parts. At the same time we also give the classification standard of the characteristics. Finally, based on the research of the literature [3], do not require the initial condition tends to zero at infinity, we also can get the same conclusion, And it applies a wider range.
Keywords: Conservation Law; characteristics; Non-degenerate minimum point;
