Abstract: Ge1-xSnx是一种新型IV族合金材料, 在光子学和微电子学器件研制中具有重要应用前景. 本文使用低温分子束外延(MBE)法, 在Ge(001)衬底上生长高质量的Ge1-xSnx合金, 组分x分别为1.5%, 2.4%, 2.8%, 5.3%和14%, 采用高分辨X射线衍射(HR-XRD)、卢瑟福背散射谱(RBS) 和透射电子显微镜(TEM)等方法表征Ge1-xSnx合金的材料质量. 对于低Sn组分(x≤ 5.3%)的样品, Ge1-xSnx合金的晶体质量非常好, RBS的沟道/随机产额比(χmin)只有5.0%, HR-XRD曲线中Ge1-xSnx衍射峰的半高全宽(FWHM)仅100" 左右. 对于x=14%的样品, Ge1-xSnx合金的晶体质量相对差一些, FWHM=264.6".

Abstract: 用二次阳极氧化方法制备出分立、双向贯通并且超薄(500—1000 nm)的多孔阳极氧化铝膜,贴合到硅片上进行干法刻蚀,实现图形转移,得到了硅基纳米孔阵列结构,并对工艺中影响图形转移质量的因素进行了探索.扫描电镜(SEM)测试结果表明该途径得到的纳米结构孔形态均匀且大面积有序,孔深度可达到125 nm.对该样品进行热氧化处理后进行光致发光(PL)测试,结果表明其光致发光机理是基于通常较微弱的TO声子辅助的硅带边发光,并实现了显著发光增强,对这种增强效果的物理机理进行了理论分析.该结构具有的独特光学特性为利用

Smart Grid (SG) , 2016, DOI: 10.12677/SG.2016.61001
This paper extends the design idea of “horizontal coordinate, vertical penetration” to dispatching management business between Power Grid and Power Station, and designs an interconnected mode which involves cooperative scheduling business processes and data unification. This paper also achieves the integrated management of dispatching business of Power Grid and Power Station, and builds a unified business and interactive structure system in heterogeneous systems of different enterprises between Power Grid and Power Station, which has a good compatibility and maneuverability.
The Design and Development of Grid-Station Dispatching Operation Management Platform

周安, , 温柏, 朱国锋,
Smart Grid (SG) , 2016, DOI: 10.12677/SG.2016.62011
This paper analyzes the Grid-Station business type of coordinated scheduling (process interaction, non-process interaction), follows OS2 standards while considering the demands of generation- side centralized access and distributed application. This paper develops coordinated scheduling operation management and technology support platform with two methods, which are function integration of application and processes access of dispatch management. This platform achieves the unified management of dispatching operation business of Power Station, which is compatible and expansible and also can simplify the access complexity for users. Furthermore, this platform strengthens the unified supervision for Grid-Station interactive business and supplies an effective support.

OCTOPUS:A New Method for Color Image Segmentation

Liu Shaochuang,Lin Zongjian,<br>刘,林宗
中国图象图形学报 , 1997,
Abstract: A new mothod-called Octopus for color images segmentation which is robust,rapid and free of tuning parameters is presented in this paper. It acquires this properties by the synergy of seeded region growing, Snake(Active Contour Models) and Operator of the computer. The process of objects extraction starts with a SRG. The region boundary are modified by Snake on the basis of considering the boundary smoothness and variation of image gradient along the boungary. We illustrate the properties of Octopus on real image where the color information of the object are used.
