| Abstract: | In this paper, an infinite dynamic system is derived to describe the relationship between shock waves and their nonuniform propagating media. Here the problem concerned is reduced to a set of ordinary differential equations(ODEs) involving the background parameters velocity v o(r) ,density ρ 0(r) and pressure p 0(r) .Theoretically ,the entire information for the shock can be obtained by sorting to the numerical solutions to the set of ODEs easily. |
