大学生诚信状况与大学体育的诚信教育

诚信乃人安身立命之本,更是一个民族和社会赖以生存和发展的重要条件。作为未来国家建设者和接班人的大学生由于受到历史传统、社会、家庭、学校教育及本人素质的影响,诚信缺失现象日益突显。因此,加强大学生诚信教育迫在眉睫,而在高校体育工作中贯彻诚信教育具有特殊意义,应该通过多种途径和方法渗透诚信教育,共同推动大学生诚信教育的健康发展。     

Analyzing and Designing Business Processes Management System Based on Transformation of Instantiated Ontology＇s State

The paper discusses efforts of finding a simple and transparent method to analyze business processes and developing its management system architecture. By introducing ontology and its state, the approach tried to find a unified representation and a flexible choreography of business processes. The main idea of the paper is the transformation of ontology＇s states, which are the most important scenarios of enterprises. The business activity composition, that is, case composition based on an AI technique, Case Based Reason （CBR）, which is to solve new problems by retrieving solutions to previous problems, and then store the modified solution. The main interest in CBR relies on that it allows a system to avoid past failures and exploit past successes.

Phase behavior of supercritical CO2 microemulsion with food-grade surfactant AOT

Supercritical CO2 (scCO2) has drawn wide attentions as a cheap and efficient green solvent replacing the conventional organic solvents. These technological ap- plications increase rapidly especially in food-relative industry, such as extractions of beer h…     

Two typical phenomena from the numerical simulation of fire and smoke transport in a gymnasium fire

Building a large centralized atrium in a building has become favourable both to designers and owners. The space of an atrium in a hall, theatre or gymnasium, can occupy an area as large as thousands of square meters and a height as high as 10―30 meters[1…     

Genetic analysis and molecular mapping of a presenescing leaf gene psll in rice （Oryza sativa L.）

A rice psl1 （presenescing leaf） mutant was obtained from a japonica variety Zhonghua 11 via radiation of ^60Co-γ in M2 generation. Every leaf of the mutant began to wither after it reached the biggest length, while the leaves of the wild variety could keep green for 25--35 d. In this study, genetic analysis and gene mapping were carried out for the mutant identified. The SSR marker analysis showed that the mutant was controlled by a single recessive gene （psl1） located on chromosome 2. Fine mapping of the psl1 locus was conducted with 34 new STS markers developed around psl1 anchored region based on the sequence diversity between Nipponbare and 93-11. The psl1 was further mapped between two STS markers, STS2-19 and STS2-26, with genetic distances of 0.43 and 0.11 cM, respectively, while cosegregated with STS2-25. A BAC contig was found to span the psl1 locus, the region being delimited to 48 kb. This result was very useful for cloning of the psl1 gene.     

基于小波变换和模糊聚类的自适应水印嵌入方法

利用人类视觉系统(HVS)的掩蔽效应和小波多分辨率分析的特点,作者提出了一种通过在图象的小波域的细节部分进行模糊聚类来寻找适合嵌入水印的位置,再用隶属度作为嵌 入强度来嵌入水印的新的数字水印嵌入算法.实验表明该方法能在保持图象质量的前提下提高水印的鲁棒性.     

一类基于二部图的（g，f）-2-覆盖图的研究

一个图G称（g,f）-2-覆盖图，如G的任何两条边都属于它的一个（g,f）-因子．本文得到了如下结论：（i）当g≤f时一个二部图是（g,f）-2-覆盖图的一个充分必要条件；（ii）当f（x）=f（Y）时一个二部图是f-2-覆盖图的一个充分必要条件．     

圈养山魈昼夜活动节律的研究

2001年1-9月，在成都动物园用扫描取样法对人工饲养条件下7只（6♀♀，1♂♂）山魈的昼夜活动节律进行了观察．结果表明：山魈一天的活动时间集中在7：00-20：00，占总活动时间的95．30％，活动高峰有2个，最高峰16：00-18：00，次高峰9：00-10：00；12：00-14：00是白天活动的低谷，夜晚几乎都为睡眠；季节不同昼夜节律有变化，夏季每天开始活动的时间早，休息时间晚，冬季则相反，每天开始活动的时间延迟，休息时间提早．
