prerotation的參考例句
1.Therefore the prerotation coefficient and the resistance coefficient could be used as major parameters to evaluate the performance of IGV. 針對風機調節門的流動特性，採用預旋係數、阻力係數做為全面評價風機調節門性能的主要指標是可行的。
2.The optimal gap between IGV and the impeller is about 4~8 times the length of the blade chord considering the symmetry and prerotation of the flow field. 從兼顧流動均勻性和預旋兩方面因素考慮，從調節門出口到葉輪進口之間的最佳距離約為葉片平均弦長的4~8倍。
3.This paper introduced the energy saving principle of air intake prerotation adjustment and the application area and method of air intake prerotation regulator. 介紹了進氣預旋調節的節能原理及進氣預旋調節裝置的應用範圍和使用方法。
