Phonics：中国人英语学习方法的革命

自然拼读法在字母的发音和单词的发音及拼写之间建立起直接的联系,把单词的“音”与“形”相结合,符合语言学习的规律。与“国际音标”相比,该方法只有两个标注符号,简单易懂,有助于学习者掌握字母或字母组合的发音与拼写之间的对应关系,快速提高学习者的单词拼读与拼写能力,是中国人英语学习方法的一次革命。     

ITER下边界局域模线圈1/4模型电磁分析

边界局域模线圈是国际热核聚变实验堆中用来抑制边界局域模现象的核心部件,在正常运行情况下,线圈中的电流和外部的背景场相互作用,在线圈上产生巨大的磁场和电磁力。由于边界局域模线圈通过螺栓连接固定在真空室内壁,在电磁载荷的冲击下会在线圈的铠甲和支撑部件上产生较大的剪切应力,一旦Tresca应力超出材料的设计应力强度阈值,线圈的设计寿命和可靠运行将受到严重影响。文章根据麦克斯韦方程计算线圈上的磁场大小和电磁力分布,并将电磁力作为外部边界条件,借助有限元分析工具ANSYS提取线圈上的剪切应力,基于ASME标准,采用分析设计的方法对应力进行分类评定,验证了设计方案的可行性。     

工程建设管理的实践——以三峡工程为例

论述了工程项目管理的三阶段划分的普遍意义。工程项目管理既有普遍的规律,也有各自的个性,因此无须强调工程管理的固定模式。应该坚持从实际出发,科学地进行管理,创造各自的管理特色。以三峡工程为例论述了工程建设和管理的实践。     

比较文学的人类学视野——中国比较文学学会第九届年会暨国际学术讨论会文学人类学小组讨论侧记

2008年10月12日,在北京语言大学召开了“中国比较文学学会第九届年会暨国际学术讨论会”。大会在两个方面体现了人类学对比较文学视野的开拓：一、比较文学的人类学转向：跨文化研究中的文化多样性及地方性问题;二、文学人类学的追问：文学的概念和功能究竞是什么？     

The role of banks in the Brazilian interbank market: Does bank type matter?

This paper analyzes the Brazilian interbank network structure using a complex network-based approach. Results suggest a weak evidence of community structure, high heterogeneity of the network and that this market is characterized by money centers having exposures to many banks. Furthermore, we go beyond the structure of the network using information about the characteristics of the nodes and a non-parametric test in order to understand the role of the banks in the interbanking market.     

中低纬度电离层偶发E层电波传播建模

基于电离层偶发E层(sporadic-E,Es)对电波传播的多条链路实测数据,认为电离层Es对入射电波的作用是反射和散射两种机制,且反射/散射的比例常数随着电离层Es临界频率的变化而变化,进而建立了包含反射、散射以及反射与散射共同作用的三段式电离层Es电波传播模型,并与国际电联(International Telecommunications Union,ITU)给出的Es层传播的电波场强预测模型进行了对比,验证了本文所建模型的正确性.该模型尤其适用于中低纬地区甚高频信号经Es层的传播研究.     

The development of gas standards and calibration techniques for measurements of vehicle, aircraft and industrial emissions, natural gas, occupational exposure and air quality

 The National Physical Laboratory (NPL) is involved in the dissemination of nationally traceable standards to which measurements of air quality, occupational exposure and air pollution source emissions, and natural gas analyses, can be referenced. This has required the development of national primary gas standards using absolute gravimetric and other techniques, and the development of dynamic calibration techniques for gaseous species which would be unstable in high-pressure cylinders. The methodology used for preparing gas standards gravimetrically is described, together with the rigorous quality assurance measurements and consistency checks which are used to demonstrate their accuracy and stability. The uncertainty budget assigned to these standards will also be summarised. NPL primary standards are used to certify traceable 'secondary' gas standards which are disseminated so as to ensure the accuracy of gas analysis measurements. Examples of the applications of these secondary standards are presented. The gas standards are employed in proficiency testing of industrial stack-testing organisations, and results of the initial rounds are presented. NPL gas standards are also now being used as the basis of the United Kingdom Environment Agency's new type-approval and certification scheme for continuous industrial stack-emission analysers. A recent important international initiative, in the field of gas analyses, is the agreement by national standards laboratories across the world to demonstrate the equivalence of their calibrations, by means of key comparisons between them. These worldwide key comparisons are complemented in Europe through the EUROMET initiative which seeks to establish the equivalence and comparability of calibration standards held at national standards laboratories across Europe. Examples of these intercomparisons are presented. Received: 23 March 2000 / Accepted: 18 August 2000

国际直接投资周期理论对中国的适应性探讨

根据中国近年的对外投资情况,检验国际直接投资周期理论在中国的适应性。检验的结果显示国际投资周期理论有很高的适应性,并且经过对理论进行的实证研究,表明中国正处于国际直接投资周期的第二阶段。然而,中国在符合国际直接投资周期理论的同时,还具有其自身的特点。     

The Greek banking system: Reanalysis of performance

Zopounidis et al. used an ordinal regression analysis to assess an additive utility model and to obtain final ranking of a representative sample of commercial Greek banks [C. Zopounidis, D.K. Despotis, E. Stavropoulou, Multiattribute evaluation of Greek banking performance, Applied Stochastic Models and Data Analysis 11 (1995) 97–107]. In this paper, we reanalyze their data by means of a new multivariate analysis method called Co-plot, a two-dimensional graphic display technique designed to analyze observations (e.g., 16 banks) and attributes (e.g., 7 attributes) simultaneously. The method produces three results: (1) similarity among the banks by the composite of all attributes involved (five clusters are obtained), (2) the structure of correlations among the attributes (three clusters are obtained), and (3) the mutual relationships between the banks and the attributes. The banks are mapped into a partial order according to their (increased) performance to obtain their rating. The final ranking obtained by the Co-plot method differed from that obtained by Zopounidis et al.
