The relationship between the ratio of Ca to Si with shrinkage value was needed to be studied further.The strength of M-AAS was comparatively high, but the flexural strength was regressed in the long term. The compressive and flexural strengthes of 3 days were able to surpass 8MPa and 78MPa, respectively, and compressive strength of 90 days were all around 100MPa, but compared to flexural strength of 28 days, the flexural strength of 90 days was regressed by 19.0%. The high strength property of M-AAS associated with its hydration products and Interfacial Transition Zoo. The main hydration products of M-AAS were microcline and CSH, no calcium hydroxide was found. The coexistence of microcline and CSH worked as micro-aggregate by each other, and no weak ITZ, both resulted in its high strength. The regression of its strength was related to its high shrinkage property, because the crazing caused by shrinkage would decrease the strength, especially the flexural strength.

M-AAS强度较高，但长期抗折强度倒缩。3天抗折和抗压强度分别可超过8MPa和78MPa，90天抗压强度在100MPa左右，但90天抗折强度比28天抗折强度相比低19.0％。M-AAS的高强特性与其水化产物和界面过渡区有关，M-AAS的水化产物主要为微斜长石和CSH凝胶，没有氢氧化钙，微斜长石与CSH凝胶相互填充和配合共同起到强度的作用，M-AAS砂浆中几乎没有发现界面过渡薄弱区。M-AAS的强度倒缩现象与其收缩值较大有关，收缩会引起M-AAS硬化体内部出现微裂缝，使强度下降。

The effects of velocity and time of high-energy ball milling on the structure and the micrograph of Y-Al-Mg-Si-O-N powder were investigated.

通过X线衍射和扫描电子显微镜观察，研究球磨转速和球磨时间对Y-Al-Mg-Si-O-N氧氮玻璃原料粉末结构和形貌的影响。

Microparticle can carry antisense MCP-1 gene into aorta successfully, which can inhibitate MCP-1 gene expression, microphage infusion and slow down the development of AAA. At the same time, there is no MCP-1 gene expression in other position, suggesting the microparticle si an secure gene transfer carrier.

以微粒子为载体，能成功地将反义MCP-1基因导入动脉组织中，并能明显抑制内源性MCP-1基因的表达和巨噬细胞在动脉壁的浸润程度，减缓腹主动脉瘤的进一步生长，同时外源基因在机体的其他部位没有表达，提示微粒子是一种安全的基因转移载体。

In this thesis, we focus on the microstructural and optoelectronic properties of doped nc-Si:H films and their related device application.

在本毕业论文中，我们主要讨论掺杂氢化纳米硅薄膜的微观结构和光电特性以及相关的器件应用。
