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。Based on sndm technique, a method of local capacitance - voltage characteristic characterization of ferroelectric thin films was proposed. the effect of traps at oxide - semiconductor interface on metal - oxide - semiconductor structure capacitance - voltage curve was discussed, and the influence of coercive field to the capacitance - voltage characteristics of ferroelectric thin films was also discussed. the dynamic switching of ferroelectric domain in ca doping ( pb, la ) tio3 thin film was studied by sndm from the view of electricity
利用sndm ，從純電學的角度觀察了plct薄膜中的電疇動態反轉過程，由電疇橫向擴張的移動速度的降低，發現了晶界在電疇反轉過程中對疇壁移動的阻擋作用;根據sndm和pfm的在垂直方向上的不同信息敏感深度，得到plct薄膜中電疇反轉過程中電疇是楔形疇;用pfm觀察同一電疇在去掉外加反轉電場后電疇的極化弛豫現象，結果表明空間電荷是發生極化弛豫的主要原因。A solid - waste containment system can be simplified as a slope which contains a layer of geomembrane ( which is simplified as interlayer slope in the rest part ). shaking table model test and numerical analysis have been done to study the seismic stability of interlayer slope based on the two - part wedge theory in this paper. many factors which affect the slope stability ratio, including horizontal seismic coefficient, slope angle, soil - geomembrane interaction coefficient, slope length, layer thickness and soil character, have been took into consideration
