中文摘要：

有为 isentropic 的概括 Riemann 问题的纸担心与驱散流动，并且看那 Riemann 问题的类似答案是否由一个向后集中的变成稀薄波浪和一个向前集中的变成稀薄波浪组成，然后概括的 Riemann 问题在 t 上承认一个唯一的全球答案 0。这个答案作为他们的中心与起源由向后集中的波浪和一个向前集中的波浪组成然后为 t 连续 > 0。

英文摘要：

The paper concerns with generalized Riemann problem for isentropic flow with dissipation, and show that if the similarity solution to Riemann problem is composed of a backward centered rarefaction wave and a forward centered rarefaction wave, then generalized Riemann problem admits a unique global solution on t≥0. This solution is composed of backward centered wave and a forward centered wave with the origin as their center and then continuous for t 〉0.
