摘　　要：本文通过直接求解N-S方程,研究激波问题,对是否可以和如何用直接求解N-S方程来处理超跨声速流进行了探索,在对粘性项的处理建立可压缩流体的压力校正方程和计算方法等方面均提出并实施了新的方法,最终得到了基本合理的数值计算结果。The shock problem is studied by direct solving N-S equations. Explorations are made of whether supersonic and transonic flows can be solved by direct solution of N-S equations, and how to do it. New approaches to treatment of viscous term, construction of pressure correction equation for compressible flow and numerical methods are proposed and adopted in the paper. Computational results obtained are basically reasonable.
