工业化的涵久及中国工业化发展的特征

工业化表现为一个农业收入在国民收入中比重和农业人口的总人口中的比重逐渐下降，而以工业为中心的非农业部门所占比重逐渐上升的经济结构变化过程。工业化是人类社会经济发展的必经之路。中国工业化的特征可以分别从发展进程、发展战略、发展速度、发展模式、发展道路、发展动力、发展后果、发展趋势等多个方面进行归纳分析。     

Improved fast intra prediction algorithm of H.264/AVC

With advanced prediction modes of intra prediction, intra coding of H.264/AVC offers significant coding gains compared with previous video coding standards. It uses an important tool called Lagrangian rate-distortion optimization (RDO) technique to decide the best coding mode for a block, but the computational burden is extremely high. In this paper, we proposed an improved fast intra prediction algorithm including block type selection and mode decision algorithm based on analysis of edge feature of a block. Our algorithm filters out unlikely block type and candidate modes to reduce the RDO calculations. Experimental results showed that the proposed algorithm can reduce the computation complexity of intra prediction from 52.90% to 56.31%, with 0.04 dB PSNR degradation and 2% increase of bit rate.     

罗大经《鹤林玉露》诗“兴”论

罗大经《鹤林玉露》主要从两个方面对诗“兴”进行了阐说:一,提出“兴”重“观物”,且要做到“静观”与“活观”的统一;二,强调“兴”意乃“赋”、“比”之归宗,去“兴”则“赋”、“比”无所归依。上述两方面,为古典诗“兴”理论的完善作出了贡献。     

Triadic interaction in clinical task-based interviews with mathematics teachers

A clinical task-based interview can be seen as a situation where the interviewer–interviewee interaction on a task is regulated by a system of explicit and implicit norms, values, and rules. This paper describes how documenting and mapping triadic interaction among the interviewer, the interviewee, and the knowledge negotiated can be used to increase procedural replicability of the interview and accuracy of drawn conclusions about the interviewee’s thinking process. Excerpts from interviews with 25 inservice mathematics teachers working on a task to make up a problem whose solution requires division of two fractions are discussed. The excerpts illustrate the relationship between methodological decisions taken by the interviewer during the interview and the applicability of the interview output to the research questions. A divergent analysis of the interviews with these teachers, which spanned over two years and were conducted by four interviewers, is used to offer a framework for analyzing data collected in clinical task-based interviews.     

关于广东新语中两篇非屈大均写的文章

《广东新语》的作者是屈大均。但该书中的端州山水章却标明是何磻所撰述，端溪砚石章则标明是高兆所撰述。无论从题目名称抑或从具体内容来看，此两章与全书的撰述体例及与屈大均谋篇设目的宗旨不相吻合。经分析可知，此两章文字原非《广东新语》所有，是屈大均受某些特殊原因所驱使或出于某种考虑，才将它们加插到《广东新语》中去的，添加时间是在康熙二十六年之后。由于此两章文字的撰写时间及其被收入《广东新语》中去的时间皆可考，故凭此能说明《广东新语》在康熙二十六年时已经刊刻成书的说法欠妥。     

基于核密度估计多样性采集的背景建模算法

1IntroductionBackground subtraction methods are extensively ex-ploited for moving object detection in videos in manyapplications ,such as traffic monitoring[1],human mo-tion capture[2]and video surveillance[3]. The centralidea behind such methods is to segment foreground ini mage sequences taken from a fixed camera by com-paring each newframe to a model of the scene back-ground .

Conversion of CO<Subscript>2</Subscript> to useful substances with composite iron,nickel, and copper catalysts

Composite materials of Fe/Al₂O₃, which consist of small particles of iron supported by thermally stable alumina even at 500–700 °C, have been widely used in the water-gas shift reaction for natural gas reforming. Therefore, Fe/Al₂O₃ is one of the promising candidates for re-transformation of exhausted CO₂ into fuels such as alcohols and hydrocarbons. The development of a CO₂ reforming system using the composite materials of Fe/Al₂O₃ through CO₂ reduction to CO, dissociation of water into hydrogen, and methanol synthesis has been investigated. It was found that dry and steam (i.e. wet) reforming of CO₂ produced almost the same amount of CO. At a temperature above 500 °C, maximal and saturated yields of CO and H₂ from CO₂ and water were obtained. However, this CO₂ reforming system requires higher-pressure conditions from several tens to hundreds standard atmospheric pressure in order to achieve high yield and selectivity for methanol production. In this study we developed the modified CO₂ reforming system by the utilization of Ni and/or Cu instead of Fe in order to obtain other types of useful products such as CO, CH₄, and carbon, more efficiently and selectively under atmospheric pressure. When Ni or Cu was used, conversion of CO₂ was reduced to 76%, while 9% of methane was detected in the case of Ni. On the other hand, though the CO₂ conversion reduced half of the Fe, the selectivity of CO from CO₂ increased to 95% in the case of Cu.
