塑料模具材料选择的模糊综合评判

基于模糊理论,建立了塑料零件材料选择的模糊综合评判数学模型,主要讨论在塑料模具零件设计时,如何在几种可用材料中合理地选出最佳的一种。并以塑料模具型芯材料选择为例,进行计算说明。     

TREE MODELS IN THE COMBINATION OF SCIENTIFIC THEORIES WITH SPORTS PRACTIC

The rapid development of sports suggests that scientific theories shoudld be the precursor in tapping the potentialities of physical function and in achieving good results in sports. Moreover, the social effect of science and technology can be realized only by applytng to sports training. Through analysis in this pa per,three models were suggested for thecombination for science and technology with sports, which may be used for future reference in sports practice.

ExpansionTool: Concept-Based Query Expansion and Construction

We develop a deductive data model for concept-based query expansion. It is based on three abstraction levels: the conceptual, linguistic and string levels. Concepts and relationships among them are represented at the conceptual level. The linguistic level gives natural language expressions for concepts. Each expression has one or more matching patterns at the string level. The models specify the matching of the expression in database indices built in varying ways. The data model supports a declarative concept-based query expansion and formulation tool, the ExpansionTool, for heterogeneous IR system environments. Conceptual expansion is implemented by a novel intelligent operator for traversing transitive relationships among cyclic concept networks. The number of expansion links followed, their types, and weights can be used to control expansion. A sample empirical experiment illustrating the use of the ExpansionTool in IR experiments is presented.

曲径通幽处 源头活水来——隐喻在弗罗斯特诗歌中的妙用

罗伯特·弗罗斯特是20世纪美国最杰出的诗人之一,其诗歌语言口语化、浅显易懂而又蕴含深邃的哲理。作为对经验世界的虚拟、映射和悬置,隐喻手法在其诗歌中的运用,于简化处、抽象处、细节处还有曲径处都恰到好处,使得诗歌作品含义隽永,充满魅力和无限趣味,给读者和研究者带来丰富的人生体验和艺术美感。     

IT strategy and decision-making: a comparison of four universities

Universities are increasingly dependent on information technology (IT) to support delivery of their objectives. It is crucial, therefore, that the IT investments made lead to successful outcomes. This study analyses the governance structures and decision-making processes used to approve and prioritise IT projects. Factors influencing an institution’s ability to identify and approve the projects that will maximise contributions to overall mission are examined. From this a framework for improved IT governance and decision-making in a university context is proposed.     

阿尔茨海默病实验动物模型方法及评价

阿尔茨海默病（Alzheimer＇s disease,AD）是一种神经退行性疾病,临床表现为认知功能障碍,病理学研究发现脑萎缩,细胞外老年斑（senile plaque,SP）沉积及细胞内出现神经纤维缠结（neurofibrillary tangle,NFT）.AD发病机制尚不清楚,因此动物模型的建立对探索其发病机制具有重要意义.该文就AD实验动物模型研究进展作一综述,详细描述并评价了目前常见的AD模型及其在药物研发中的应用.

实践理性视域中的教学模式构建

理性由理论理性和实践理性构成,实践理性有价值理性、工具理性和过程理性三种形式。教学模式构建的实践理性表现为价值理性、工具理性、情境理性和过程理性,其不同的旨趣体现为追求模式构建的价值、获取合理的技术手段、凸显模式构建的情境知识、揭示模式构建的历史品性,从而使模式构建的实践理性呈现价值引领与规范、伦理性、交往性和反思性特征。确立模式构建的实践发展方向,立足人的生活世界,建立模式构建共同体,青睐实践改进的研究方法,生成模式构建的实践智慧是基于实践理性的模式构建策略。
