论社会环境对宋代文学发展的影响

宋代学在我国学发展史上具有承前启后的历史地位。而宋代学的辉煌及其所表现出来的独特风貌，是与当时的社会环境紧密相连的。本把宋代学的发展分为四个阶段(北宋初期、北宋中叶、南宋初期及南宋末年)就这四个时期的社会环境以及在其特定的环境下涌现出的杰出作家做了初步的论述。     

一种流媒体Caching策略

It is expected that by 2003 continuous media will account for more than 50% of the data available on origin servers, this will provoke a significant change in Internet workload. Due to the high bandwidth requirements and the long-lived nature of digital video, streaming server loads and network bandwidths are proven to be major limiting factors. Aiming at the characteristics of broadband network in residential areas, this paper proposes a popularity-based server-proxy caching strategy for streaming media. According to a streaming media popularity on streaming server and proxy, this strategy caches the content of the streaming media partially or completely. The paper also proposes two formulas that calculate the popularity coefficient of a streaming media on server and proxy, and caching replacement policy. As expected, this strategy decreases the server load, reduces the traffic from streaming server to proxy, and improves client start-up latency.     

International orientierte höhere Schulen in Deutschland – Zwei Varianten von Internationalität im Wechselspiel von Institution und Schülerbiografie

During the last decades, the education system has been marked by distinct processes of internationalisation. In the field of higher education, there are numerous and varied schools with different international profiles. This paper focuses on processes of internationalisation in the German sector of higher education. We contrast two higher secondary schools with international profiles: one international school in a West German metropolitan region with a long tradition and a younger internationally-profiled school located in the periphery of an East German urban centre. This institutional analysis presents school cultural similarities and differences with regard to different claims and concepts of internationality. This analysis is complemented by a reconstruction of three patterns of biographical meaning examining the internationality of pupils and their respective habitual fit to these internationally-profiled schools. We draw on qualitative data, consisting mainly of interviews with head teachers and pupils of these two schools. We argue that these differing regional forms of internationalisation indicate a stratification and hierarchisation in the field of higher education in Germany.     

Modeling of D-STATCOM in distribution systems load flow

This paper presents modeling of Distribution STATCOM (D-STATCOM) in load flow calculations for the steady- state voltage compensation. An accurate model for D-STATCOM is derived to use in load flow calculations. The rating of this device as well as the direction of required reactive power injection for voltage compensation in the desired value (1 p.u.) is de- rived and discussed analytically and mathematically by the phasor diagram method. Furthermore, an efficient method for node and line identification used in load flow calculations is presented. The validity of the proposed model is examined by using two standard distribution systems consisting of 33 and 69 nodes, respectively. The best location of D-STATCOM for under voltage problem mitigation approach in the distribution networks is determined. The results validate the proposed model for D- STATCOM in large distribution systems.     

浅析法与利益

法与利益作为法理学中的一个重要命题而倍受关注。当法律作为一种上层建筑作用于社会的整个结构时，最为直观的反映是对利益的平衡作用，并在此过程中对利益加以权衡。当然，社会中利益的协调仅仅借助法律的平衡是难以实现的，同时也需要法律的保障功能的发挥。     

大学化学实验课教学改革的探索

结合教学改革的实践对当前化学实验存在教学体系陈旧、各门实验课相对独立、学时分散、教学内容多次重复、课时浪费等缺陷进行改革研究，提出改革教学体系，整合实验内容，精选实验方案，强化实验教学全程管理的对策．     

经济全球化对我国的影响及其对策

现实中的经济全球化是资本的跨国流动和政府与社会向这种流动的被动让步所构成。大量国际资本的进入，对我国经济发展既有正面影响。又有负面影响。我国既要利用经济全球化所带来促进经济发展的历史机遇，又不能盲目跟随所谓“国际分工的规律”，而要采取一切可能的手段，趋利避害，强化自身。     

贵州省苗族地区中小学民族文化课程开发的个案研究

通过对贵州省苗族地区中小学民族文化课程开发现状的个案调查，发现民族地区民族文化课程开发还停留在浅层面，学校课程尚未成为民族文化传承的主渠道，地方课程资源开发不力，致使学生对民族义化疏于了解。就此认为民族地区基础教育民族文化课程的开发应从观念层面、政策层面、支持系统及实践层面等方面进行，以推进民族文化课程的实施。     

既有桥梁浅基加固防护体顶面标高确定方法的探讨

本文以陇海线某铁路浇基桥梁的加固防护设施为工程背景，分析了该浅基桥梁被洪水冲毁的主要原因。并针对既有加固防护体项面与河床最低点之间存在高差的问题，提出了合理确定该高差最大的值的方法。     

Multi-frequency proportional-resonant （MFPR） current controller for PWM VSC under unbalanced supply conditions

This letter presents a multi-frequency proportional-resonant （MFPR） current controller developed for PWM voltage source converter （VSC） under the unbalanced supply voltage conditions. The delta operator is used in place of the shift operator for the implementation of MFPR by using a low-cost fixed-point DSE The experimental results with an alternative control strategy validated the feasibility of the proposed MFPR current controller for the PWM VSC during voltage unbalance.
