  1. As an advanced materials preparation technology, spray - deposition has shown remarkable superiority in producing large - sized alloys and metal matrix composites. however, the spray deposeted preforms usually contain a certain quantity of porosity. besides, the oxide films on the surface of the particles lead to week metallurgic conjunction between the particles. in order to obtain an ideal structure and performance, the porous preforms need further densifying and plastical forming. in this paper, a new technology named wedge pressing was used to densify spray - deposeted 5a06 aluminium alloy, in which the large deformation can be obtained through the sum - up of local deformation and multi - step small deformation. this method can also solved the problems in traditional processing and greatly decreased the producing cost. what ’ s more, the reserch on the wedge pressing desification rules about the large - sized spray deposeted preforms was significant it was vital not only to the further densification of the prefoums but also to the further research on plastical deforming the research was also benefit to the industrialization an the application of the spray deposeted porous materials

    坩堝移動式噴射沉積技術作為一種先進的材料制備新技術，在制備大尺寸合金及金屬基復合材料方面具有顯著的優越性。然而噴射沉積坯件特別是大型坯件通常存在一定量的孔隙，顆粒表面存在一定量的氧化膜，顆粒之間未能完全達到良好的冶金結合狀態，因此需要進行后續緻密化和塑性變形才能獲得理想的組織和性能。本文採用一種新型的楔形壓制工藝，即通過局部變形、多道次小變形累積實現大變形的緻密化加工方法，對噴射沉積多孔坯料進行后續緻密化和塑性變形，很好地解決了傳統加工工藝的難題，大大降低了生產成本。
  2. Another important aspect in the manufacture of these valves is the clearances at the critical metal interfaces ( wedge / body guides, stem / back seat bushing, etc. )

    這種閥門的製造中的另一個重要方面是關鍵金屬表面（楔形閘板/閥體導向，閥桿/后閥座襯套，等等）的之間的間隙。
  3. The distribution of the gas - flow speed is measured at a position 1cm away from the outlet ( the end with larger air - gap ). it is illustrated that the gas - flow speed keeps increasing from the out surface of the inner sleeve to the inner surface of the outer sleeve, and then it decreases gradually

    測量了楔形氣隙流體出口（大間隙埠）外1厘米處空氣流速大小的分佈，發現空氣流速自轉子（內筒）壁面處開始逐步增大，至定子（外筒）壁面處達到最大值，隨后開始減小。
  4. With this axial symmetric quasi - 3d model, the gas - flow field in such a wedge - shape air - gap is studied, the phenomena about taylor vortex in such a narrow wedge - shape air - gap is illuminated and the so caused gas - flow in axial direction is explained
