過渡壓縮 的英文怎麼說
中文拼音 [guòdùyāsuō]
過渡壓縮
英文
supercompression-
In lifting - surface theory, the non - liner phenomena of the trailing vortex in the transition wake area and of the tip vortex separation are considered. in surface panel method hyperboloidal quadrilateral panels are employed and the morino ' s analytical formulation is used to determine the influence coefficients. the more reasonable pressure kutta condition is satisfied at the trailing edge of propeller blade
在計算中，對于升力面理論，本論文考慮了過渡區尾渦收縮和葉梢分離的非線型現象的影響；對于面元法，本論文採用的是計算較為簡便的基於擾動速度勢的基本公式及雙曲面形狀的面元，在槳葉隨邊滿足更趨合理的壓力kutta條件，並用morino導出的解析公式計算面元的影響系數的快速有效的數值預報方法。Through the experiment, it is found that, when the compression percentage closes to 20 %, the compression pressure at the far end changes quickly and differs from that at the near end ; and when the compression percentage is less than 20 %, the compression pressure at the near end rises quickly and that at the far end transits from instability to reverse distribution state
實驗研究表明，冠狀動脈面積收縮接近到原來的20 %時，遠段收縮壓迅速與近段收縮壓分離；當冠狀動脈面積收縮到小於原來的20 %時，近段收縮壓迅速上升，遠段壓力從不穩定狀態迅速過渡到收縮壓呈反向分佈狀態。The advanced development on the new kinds of scroll profile has become the research focus in the profile design. used a new type scroll compressor of the combination profile in this paper, a scroll is constructed following this : the inner turn consists of the standard involute of circle, and the same to the outer turn. then the middle turn is one of arc
本文所研究的新型組合曲線渦旋壓縮機最內圈以基圓漸開線構成，中間段以圓弧過渡，最外圈由圓漸開線構成，能發揮不同型線的優勢，是一種能滿足多性能較優要求、形狀性態良好的渦旋型線，與傳統的基圓漸開線構成的渦旋壓縮機相比，具有效率高、泄露量少、體積利用系數大等優點。The physical experiments and theories on thermodynamics prove that gas thermal insulation coefficient changes apparently when hydraulic transition process happens. so four appropriate processes were given - sub - process 1 of compressing, sub - process 2 of inflating, sub - process 3 of inflating, sub - process 4 of compressing
試驗與理論分析表明，在管道系統發生水力過渡過程時氣體多方指數n存在較為顯著的變化，並非單一常數，從而提出了相應的四過程：即壓縮子過程1 、膨脹子過程2 、膨脹子過程3和壓縮子過程4 。分享友人
