提出一种诊断方法，只要测量了多级轴流压气机的进出口流场及外端壁若干个静压值，在不依赖于任何叶片排的冲角和落后角以及计算站的堵塞因子的经验系数或模型的情况下，就能够诊断出多级轴流压气机的重要部位流场参数的径向分布。方法本身不受设计工况和非设计工况的限制。
A diagnosis method is proposed in this paper as long as the inlet and outlet flow field and the static pressure value of the outer end wall of a multi-stage axial compressor are measured, and without depending on the angle of incidence and the backward angle of any blade row and the block factor Empirical coefficient or model case, the radial distribution of the flow field parameters of the important part of the multistage axial compressor can be diagnosed. The method itself is not subject to design conditions and non-design conditions.
