共轭梯度法研究超晶格GaAs/AlxGa1－xAs的电子结构

改进了一种从头计算方法—共轭梯度方法 ,研究了超晶格 Ga As/ A lx Ga1 - x A s的电子结构 .根据超晶格的基本方程 ,在固定电子密度 n(z)下 ,求解了基本方程的本征值和本征函数 ,并由它们组成新的 n(z) ,重复此过程直到得自洽解 .另按超晶格基本方程的具体情况 ,对每个 kz独立地应用了共轭梯度方法 ,此可大大节省与 Gram-Schm it正交化有关的时间 .计算了超晶格的两个最低子能带之间的能量差和 F ermi能量 ,其模拟计算的结果与对应的实验数值一致     

Comparison of distribution characteristics of asbestos cement slates in rural and urban regions of Korea

The toxicity of asbestos has been constantly an active research topic. Although asbestos has lots of advantages owing to its stable physicochemical properties and economic characteristics, nations enforce policies prohibiting or limiting its use because of its critical impact on human health. Especially in Korea 96% of imported asbestos are slate construction materials and with the influence of Saemaul movement, thatched roofs have been drastically replaced with slate roofs. Efforts to know the distribution characteristics of extensively used asbestos cement slates and to find out the removal method that suits the distribution characteristics are still in an insufficient state. The purpose of this work was to probe into the distribution of asbestos cement slate buildings in Korea and provide basic data of distribution characteristics for policy making in which consideration of the differences between rural and urban regions is necessary based on findings of the studies so far. It is considered helpful in many ways to solving asbestos cement slate related problems in countries where asbestos usage is increasing even after the 2000s including China.     

韩国留学生介词"向、往"使用情况的考察

表动作趋向的介词"向、往"是学汉语的韩国学生在使用方面偏误率较高的介词之一。本文对韩国学生使用"向、往"的情况进行了调查,分析干扰韩国学生掌握使用介词"向、往"的原因,并从本体和汉韩对比两个角度对"向、往"这两个介词做出较为细致的比较,从多个角度得出对韩国留学生进行介词"向、往"教学的一些启示。     

Ultimate strength of single shear bolted connections with cold-formed ferritic stainless steel

This paper is focused on the structural behavior of the single shear bolted connections with thin-walled ferritic stainless steel.The purpose of this study is to investigate the ultimate behaviors,such as ultimate strength and fracture mode of the single shear bolted connections of thin-walled ferritic stainless steel(low cost steel) rather than austenitic stainless steel(high cost steel).Bolt arrangement and end distance parallel to the direction of applied load are considered as main variables of the test specimens for bolted connections.Specimens have a constant dimension of edge distance perpendicular to the loading direction,bolt diameter,pitch,and gauge.A monotonic tensile test for specimens has been carried out and some bolted connections with long end distance showed curling(out of plane deformation) occurrence which led to strength reduction.The ultimate behaviors such as fracture mode,ultimate strength are compared with those predicted by current design codes.Further,conditions of curling occurrence and the strength reduction due to curling are investigated and modified strength equations are suggested considering the curling effect.

Wagner模型自洽性分析

为深入理解 N d0 .52 Sr0 .48Mn O3薄膜中的庞磁电阻效应 ,运用数学解析以及物理概念分析的方法 ,对 Wagner等人提出的在 Nd0 .52 Sr0 .48Mn O3薄膜中庞磁电阻随磁场变化规律的模型进行了分析 ,并对该模型的自洽性进行了讨论 .结果发现只有通过某些必要的修正 ,Wagner模型方可自洽 .还研究了 Nd0 .52 Sr0 .48Mn O3薄膜中大自旋极化子 (large spin po-larons)在居里温度附近的行为特征 ,发现在居里温度附近磁性团簇的尺寸变化较为异常 ,对此现象的物理机制进行了初步探讨
