Interaction Theory of Asphalt and Rubber高英Transportation School, Southeast University摘 要:Through scanning electron microscope (SEM), spectral analysis, and component analysis tests, the interaction theory between asphalt and rubber was discussed. It is concluded that rubber powder become soft and bond together with each other after being mixed......
溅射沉积法制备金薄膜的结构特性 许小亮1,关博3,江勇1 (1.中国科技大学,物理系,安徽,合肥,230026;2.中科院结构分析重点实验室,安徽,合肥,230026;3.中国科技大学,少年班,安徽,合肥,230026) 摘要:在不同的生长阶段Au膜具有不同的表面微结构.随着厚度的增加,薄膜晶粒要经历成核,正常晶粒生长和反常晶粒生长过程,在不同的过程中Au膜呈现出不同的表面形貌.在正常晶粒生长阶段,薄膜晶粒呈柱状生长;随后的反常晶粒生长过程中会出现晶粒吸收现象,使具有较优取向的晶粒越长越大.X射线衍射图(XRD)显示Au膜具有(111)面取向优势.利用LSW理论模型计算并解释了晶粒反常生长过程. 关键词:表面形貌; 正常晶粒生长; 反常晶粒生长; LSW理论模型; [全文内容正在添加中] ......
