The results of numerical simulation demonstrated the development of the unsteady flow field, and the unsteady waves and vortexes were discussed. 数值模拟结果形象地反应了非定常流场的演变，详细讨论了激波和涡等的发展变化过程。
In this paper, the effects of solidity of rotor-stator cascades on axial-flow compressor performance are investigated with steady and unsteady flow calculation. 采用定常流和非定常流计算方法研究了各种动静叶稠度组合对轴流压缩机性能的影响。
