摘要
在给出Chaplygin气体方程组Riemann问题的解后求出广义Chaplygin气体方程组当α→1^-时的Riemann问题的解.根据相应的初始条件,广义Chaplygin气体方程组当α→1^-时的Riemann问题的解与Chaplygin气体方程组Riemann问题的解均由两个接触间断或者δ-激波组成.因此,当α→1^-时,广义Chaplygin气体方程组Riemann问题的解与Chaplygin气体方程组Riemann问题的解是一致的.
After giving the Riemann solutions of Chaplygin gas equations,the Riemann solutions of generalized Chaplygin gas equa?tions were given.According to the corresponding initial conditions,the Riemann solutions of the generalized Chaplygin gas equations and the Chaplygin gas equations consist of two contact discontinuities and the delta shock wave.When the parameter tends toone,the Riemann solutions of the generalized Chaplygin gas equations and the Chaplygin gas equations are the same.
