prewhirl的參考例句
1.In this study, many kinds of experimental studies are carried out to gain a deep insight into the nature of prewhirl and inlet flow. 論文通過對離心風機進口流場的多種測量，更深一步地瞭解離心風機進口預旋的分佈、產生原因以及進口流場的流動現象。
2.The performance of the centrifugal compressor at different diffuser stagger angles and different inlet guide vane (IGV) prewhirl angles are measured. 對擴壓器進口不同安裝角和進口導葉不同預旋角匹配下離心壓縮機的性能進行了實驗研究。
3.The investigation shows the performance gets quite insensitive to the prewhirl angle of IGV as the stagger angle of diffuser vane is reduced to the minimum 7°; 研究表明：擴壓器進口安裝角最小值為7°時，壓縮機性能對進口導葉預旋角不敏感；
