摘要
研究具有一类合理粘性项的一个非严格双曲守恒律方程组的定态解．证明了对任何满足ｕ＋＜ｕ的两个状态，该粘性方程组存在唯一解．当粘性系数趋于零时。
Studies steady solutions of a nonstrictly hyperbolic system of conservation laws to which a reasonable viscosity term has been added.We prove that for any two states which satisfies u +<u -,there exists a unique solution to the viscous system.As the viscosity coefficient tends toward zero,the ω * limit in L 1of the solution is the δ-shock wave for the hyperbolic system.
