摘要 借助特征线分析法和广义Rankine-Hugoniot条件与熵条件,研究关于修改Chaplygin气体压力的非对称Keyfitz-Kranzer系统的Riemann问题,构造性求出了所有的黎曼解,其中包含了delta激波解. This paper studies the Riemann problem for nonsymmetric Keyfitz- Kranzer system of modified Chaplygin gas pressure,with the characteristic line analysis and generalized Rankine- Hugoniot condition and entropy condition,constructive obtained all kinds of Riemann solutions,which contains the delta shock solution.
