流体力学方程组的总熵增量小的守恒型差分格式

In this paper we design conservation difference schemes satisfying thermodynamic en- tropy increment condition for one-dimensional Lagrangiou gas dynamic equations. These schemes have small total thermodynamic entropy increment in some sence. Numerical experiments show that they have higher resolution and accuracy
