摘要

黎曼不变量是研究守恒律系统的一种重要方法,在许多模型中都有广泛的应用。本文利用该方法,研究了欧拉坐标系下的p系统,获得了几个有关解的全局性和有限时刻爆破的临界条件。
        Riemann invariant is an important method to research the conservation law systems, which has been applied widely in many models. Using this approach, this paper deals with the p system in Eulerian coordinates and obtains some critical threshold about the global regularity and finite-time blow-up.
