  1. We can use the mm5 model in definite time, definite area weather forecasting. we conclude that : : the moving route of this necw in its developing progress was direct - south along latitude, the cold air is rough, and just this made the rough vertical velocity ; the necw southern moving and conflicting with the west pacification sub - tropical high makes rough jet steam. the plenty south - west warm and wet air made by the jet stream gave the rainstorm demanded vapor ;. the rough vertical velocity by jet stream is a main reason in this rainstorm ; the mm5 model uses four - direction analysis data as its input, this avoids some errors occurred in observe and transfer, thus made the result more useful

    綜合分析認為： （ 1 ） 、這次冷渦在其發生發展過程中，其移動路徑是沿經圈直線南壓，攜帶的冷空氣勢力較強，形成槽后較強的垂直運動； （ 2 ） 、西太平洋副熱帶高壓偏北位置與東北冷渦南壓形成的急流軸，把源源不斷的西南暖濕氣流輸送到遼西地區，也就是急流軸的左前方位置，為這次暴雨的產生提供了充足的水汽來源； （ 3 ） 、低空急流不但為暴雨輸送水汽，其造成的較強的垂直環流也是產生強降水的一個主要原因； （ 4 ） 、 mm5模式以四維同化資料作為初始場，最大限度地避免了觀測誤差可能造成的積分不穩定，提高了模擬結果的參考價值。
  2. The main relative systems of heavy - hard rainfall in northeast plateau are western pacific subtropical high, south asia high, low latitude systems, upper level jet ( ulj ), low level greater wind speed axes, westerly trough and plateau trough, low level vortex, cold frontal, occluded front in qinghai lake, mesoscale low pressure, heat low - pressure in qinghai, shear line and convergence line, mesoscale cloud cluster, etc. the west subsidiary model of south asia high is the main circulation type of heavy - hard rainfall in this area

    3 、西太平洋副高、南亞高壓、低緯系統、高空急流、低空大風速軸；西風槽和高原槽、低渦、冷鋒、青海湖錮囚鋒以及中尺度低壓、青海熱低壓、切變線與輻合線、中尺度雲團等系統是高原東北部地區大到暴雨的主要相關系統。 100hpa上的南亞高壓中心強度加強，位置東西擺動預示高原地區將有降水產生，中心強度減弱，降水過程結束。南亞高壓西部副型是高原東北部地區大到暴雨的主要流型。
  3.

  4. ( 6 ) as dean number is increased, the secondary flow firstly becomes symmetry and then the anticlockwise vortexes are enlarged, the contours of axial velocity and the stream function become symmetry, the secondary flow is intensified and the friction factor ratio increases

    （ 6 ）增大dean數，二次流先趨于對稱而後逆時針方向的二次渦增大，軸向速度和流函數等值線趨向于對稱，摩擦系數比增大。
  5. The results showed that process parameters varied with time in fermentation was distinct for different agitator and the hydrofoil impeller instead of the disc turbine impeller might significantly reduce power consumption under the same condition

    研究結果表明： （ 1 ）與傳統的渦輪攪拌槳相比，翼形軸流槳攪拌其發酵過程參數（粘度、溶氧、效價等）隨時間的變化曲線有明顯的差異； （ 2 ）在相同的生產條件下，用冀形軸流槳代替渦輪槳可有效提高生產效率。
  6. The results show that an eddy surrounding the main stream of the multiple jets exists and forms several strong shear flows and enhances the effect of energy dissipation
