失速和喘振现象一直是离心压气机研究领域的重点和难点，对于压气机失速或喘振时的非定常效应的研究具有重要意义。
Stall and surge phenomenon are the research hotpots of centrifugal compressor. The study of steady effect of stall and surge is typically important.
逐级模型的另一种用途是用来研究压缩系统的过失速行为，本文研究了由压气机和主燃烧室组成的压缩系统。
Another application of stage-by-stage model is to investigate the post-stall behavior in the compression system which consists of one compressor and one combustion chamber.
因此，静叶弯曲后改善了近失速点的流动，扩大了低速压气机的稳定工作范围。
The flow near the stall point was therefore improved, and the stable operation range was expanded.
