多维双曲型守恒律组的正性原理和正解格式已在[X.-D.Liu和P.D.Lax，J.Fluid Dyam.，5(1996)，pp.133--156]中被引入。文中给出的一些数值实验表明了该方法的有效性。在本文中，我们使用正格式来求解二维气体动力学的黎曼问题。
The positivity principle and positive schemes to solve multidimensional hyperbolic systems of conservation laws have been introduced in [X.-D. Liu and P. D. Lax, J. Fluid Dynam., 5 (1996), pp. 133--156]. Some numerical experiments presented there show how well the method works. In this paper we use positive schemes to solve Riemann problems for two-dimensional gas dynamics.
