  • vane : n 文恩〈姓氏〉。n 1 【氣象學】風向標，風信旗；〈比喻〉隨風倒的人。2 （風車、推進機等的）翼，（導...
  • efficiency : n. 1. 功效。2. 效率；效能；實力，能力。3. 【物理學】性能。
  1. 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 ; the combination of these two stators enables to greatly improve the compressor efficiency over the entire operating rage, the maximum efficiency with the combined adjustment reaches 86. 0 %, higher than that in alone adjustment of igv or diffuser vanes by 2 %

    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；採用不同的擴壓器進口安裝角和不同進口導葉預旋角匹配調節時，壓縮機所能達到的最高效率為86 . 0 % ，比單獨調節進口導葉預旋角或擴壓器進口安裝角所能達到的效率高2 % 。
  2. The experiment shows that by changing the velocity coefficient, the separation of boundary layer on pump vane can be controlled, and the performance of pump is improved and its hydraulic efficiency

    實驗證明通過改變葉片型線參數方程中的速度系數的取值，可以控制邊界層的分離，進而改善泵的性能，提高其水力效率。
  3. Effects of different fuel - air ratios and different geometric parameters of dual - stage swirler ( such as inner diameters of the primary swirl and secondary swirl passages, outer diameters of the secondary swirl passages, vane angle of the primary and secondary swirler, the distance of the flare exit from throat etc ) on combustion performances are studied experimentally. the experimental results show that radial profiles of the outlet gas temperature 、 combustion efficiency 、 emissions of co2 、 co and nox and lean blowout are affected with different degrees by the different geometric parameters of dual - stage swirler and the arrangement of primary holes

    在不同油氣比下，不同的雙級旋流器幾何參數（例如:一級與二級旋流器出口內徑d 、葉片安裝角、二級旋流器出口外徑d 、二級旋流器的喉道到出口截面的距離l和喉道前後的圓弧半徑r以及主燃孔孔布局等）對單頭部環形燃燒室的出口溫度分佈、燃燒效率、貧油熄火油氣比以及污染物（ co _ 2 、 co和nox ）排放等燃燒性能的影響規律進行了研究。
  4. High - low pressure double vane pump with low noise level and high performance is used for energy saving and high efficiency

    採用高性能、低噪音的高低壓雙泵或單泵以省耗能量及提高生產效能。
  5. Abstract : as there were leak on contact place between shaft and rotor - body in built - up hollow rotor, dropping discharg gas speed of pump and efficiency applied of oil - sealed sliding vane rotary vacuum pump

    文摘:組合式空心轉子由於軸頭與轉子體之間的結合面存在著滲漏，使泵的抽氣效率性能下降，從而影響其在應用中的效率。
