| Abstract: | This paper is devoted to a discussion of some problems concerning the shock wave in our supernova model, including the positions of the formation point and shock front, shock velocity and shock energy. We find that (1) there exists a second shock wave besides the first one in the outer core; (2) the precise position of the shock front is located between the maximum entropy and the maximum pseudo viscosity regions. In addition we derive the relations between the different definitions of shock energy. |
