本文介绍了尖前缘翼诱导激波和湍流边界层干扰流场壁面特性，着重强调马赫数影响。

This paper presents the surface characteristics of the inter-action between shock wave and turbulent boundary layer induced by sharp fin with emphasis on Mach number effects.

对上游进口段，特别是靠近叶片前缘区域流场参数分布有较大影响，但对于上游叶片表面马赫数影响不大。

The flow field parameter distribution can be affected more in upper stream, especially near the leading edge area while the Mach number distribution of the upstream blade surface is affected little.

且不同模态下出口马赫数对非定常流动的影响规律表现不尽相同。

Moreover, the law governing the influence of the outlet Mach number on the unsteady flow under various modes is found to be not always identical.
