  1. In order to predict hydrodynamic characteristics a computational system is developed including determination of the pressure distribution on a wing section by use of the conformal mapping method and panel method respectively and of the flow in boundary layer according to the thin shear layer approximation ( tsl ) for navier - stokes equation approach. the wing sections of naca4412 and naca0012 are applied to test the computational system. the numerical inspection shows that the panel method with better precision and the momentum and the displacement thickness of boundary layer can be used to complete this calculation

  2. According to the requirement of innovation engineering in chinese academy of sciences, the work in this thesis focused on fabrication of soi material with epitaxial layer transfer of porous silicon and study of luminescence of modified porous silicon, and we obtained the following new results : the effect of doping and anodizing condition on the properties of porous silicon, including the microstructure, ciystallinity and surface morphology, has been studied systematically. it is found that the porous silicon and substrate have the same orientation and share a coherent boundary. but at the edge of pores, the lattice relaxes, which induces xrd peak moving of porous silicon

    Soi技術和多孔硅納米發光技術研究是當今微電子與光電子研究領域的前沿課題,本文根據科學院創新工程研究工作的需要,開展了多孔硅轉移eltran - soi新材料制備與改性多孔硅發光性能的研究,獲得的主要結果如下:系統研究了矽片摻雜濃度、摻雜類型和陽極氧化條件等因素對多孔硅結構、單晶性能和狀態的影響,發現多孔硅與襯底並不是嚴格的四方畸變,在多孔硅/硅襯底的上,多孔硅的晶格與襯底完全一致,但在孔的緣,多孔硅的晶格發生弛豫。
