Abstract:
电子词典是现代外语学习者常用的重要工具,在外语词汇习得中起着积极的作用。国外的研究者从多个角度探讨了电子词典在外语词汇学习中的作用,并取得了丰富的研究成果。本文对这些实证研究进行评述,介绍其研究方法、研究结果,并指出尚存的不足和有待研究的方向,一方面能为电子词典的编撰提供实证支持,同时也有助于外语教师指导学习者正确的使用电子词典,以提高其自主学习效率。
With the development of computer technology and its application in foreign language teaching, electronic dictionaries have become an indispensable tool for many language learners. There have been a wealth of studies examining the roles of electronic dictionaries in foreign language voca-bulary acquisition, focusing mainly on the following issues: comparison of the effects of electronic dictionaries and paper dictionaries on foreign language vocabulary acquisition, the influences of different modes of dictionary information on the acquisition of new words, foreign language learners’ lookup preferences while using electronic dictionaries, and how to develop appropriate learning tasks to induce foreign language learners’ deep processing of the information provided by electronic dictionaries. The present paper reviews studies probing into the roles of electronic dictionaries in foreign language vocabulary learning, introducing the research methods adopted, findings obtained, as well as potential research issues in this area. It is hoped that the study might shed some light on the development of electronic dictionaries and offer help to foreign language teachers in guiding the students to use electronic dictionaries more effectively.





试论词汇衔接带来的演讲词连贯效果——以奥巴马2009年就职演讲词为例
On the Cohesive Effect of Lexical Cohesion in Speech——With Obama’s Inaugural Address in 2009 as the Case

Abstract:
衔接是语篇中话语组织的纽带,衔接的手段多种多样。在《英语的衔接》一书中,HallidayHasan列出了五种衔接手段,即指示、替代、省略、连接和词汇衔接。前四种是语法手段,最后一种是词汇手段。本文以胡壮麟在其专著《语篇的衔接与连贯》中提出的关于词汇衔接方式的理论框架,结合奥巴马在2009年的就职演讲词,详细探讨各种词汇衔接手段在语篇连贯衔接构建中的运用,以及由词汇衔接带来的强大视听效果。
Cohesion is the connecting belt between the organizations of discourse, which is usually arrived by various methods. In Cohesion in English, Halliday and Hasan listed five methods of cohesion: reference, substitution, ellipsis, conjunction and lexical cohesion, with the first four grammatical and the last one lexical. By using the ways of lexical cohesion advocated by Hu Zhuanglin in his book—The Cohesion and Coherence in Discourse as the theoretical frame and Obama’s inaugural address in 2009 as the case, this thesis explores the uses of the ways of lexical cohesion in the construction of a coherent and cohesive dis- course in details, and at the same time demonstrates the great audio and visual effect brought by it.

Abstract:
本文选取禹州市作为调查研究对象,通过对禹州市2006~2020年土地利用总体规划相关资料的分析和研究。运用单一土地利用动态度和综合土地利用动态度阐述了该区域土地利用现状与变化情况。调查研究的结果表明:禹州市正值工业化、城镇化加速发展阶段,土地利用和保护面临严峻的挑战。目前禹州市土地利用过程中存在人口增加与耕地减少的矛盾日益明显;农用地不但投入水平低,农业生产条件不发达,更与建设用地矛盾日益激化,建设用地供需矛盾突出;内部利用结构存在问题,局部地区土地资源和生态环境遭到破坏,严重影响着土地的可持续利用。为促进禹州市土地的优化利用,应采取以下措施对策:落实土地基本国策,积极保护农用耕地;大力发展节地经济促进土地资源的集约与节约利用;顺应产业结构优化升级的需要;建立土地保护规划实施的经济调节机制。
This article selects Yuzhou city as the object of the study. Through the analysis of the general land utilization planning and relevant materials of Yuzhou city during 2006-2020 by employing the methods of single and comprehensive land use dynamic degree, the paper explains the present situation and changes of the land use in this region. Research results show that the Yuzhou city is in the stage of accelerating industrialization and urbanization, and the land utilizationn and pro-tection is faced with serious challenges. Currently, the land use of Yuzhou city demonstrates a series of characters: the contradiction between the increase of population and the reduction of farmland is increasingly obvious; the input level of agricultural land is not only low, but the agricultural production conditions is also poor; the structure of construction land is unreasonable and the contradiction between supply and demand is gradually outstanding; the internal use structure is problematic, and regional land resources and ecological environment is destroyed. They seriously affect the sustainable use of land. In order to promote the optimum utilization of Yuzhou city land, the following measures should be taken as countermeasures: to carry out the basic national policy of land and protect agricultural land actively; to put lots of effort into developing the land-saving economy in order to promote the intensive and economical utilization of land resources; to adjust to the needs of the optimization and upgrading of industrial structure and to establish the economic adjustment mechanism of land conservation planning and implementation.

平菇见光适宜时间初步研究

微生物学通报 , 1983,
Abstract: 平菇又叫白黄侧耳(Pleurotus cornucopiac)处在黑暗条件下是不会形成子实体的。而光诱导反应只限于受光照射的部分,不能通过菌丝传到非照射部分。另外一般担子菌在菌丝体形成阶段要求较高的温度,在子实体形成阶段又要求较低的温度,这种不同阶段要求不
光量和光质对凤尾菇菌丝生长的影响

微生物学通报 , 1984,
Abstract: 关于平菇属凤尾菇(Pleurotus sajor-caju)的光照问题,我们在1981年研究肯定了“当菌丝体基本长满培养基时,标志着进入了光照敏感期,就应该及时给予散射光线催其出菇”的基础上,1982年又进一步研究了光量与光质对其菌丝体生长的影响。现将其结果报告如下。
类生物量锥体——杨纪明教授提出海洋生态学中一个新概念

海洋科学 , 2008,
Abstract: 早在19世纪,就有人提出海洋里究竟有多少鱼这样一个问题。从那以后,生物学家从各个环节相继进行了研究。1935年Elton首先提出“食物链”概念。从这个概念引伸出,在海洋里藻类等初级生产力通过一级和多级转换,可以形成贝类、虾类和鱼类等渔业资源。1942年Lindeman提出“十分之一

Matching of Semantic Web Service Based on Context Constrains and Enhanced Sematic
带情景约束和增强语义的web服务匹配方法


计算机系统应用 , 2010,
Abstract: 针对目前语义web服务匹配方法中缺少对服务情景约束的考虑及传推理匹配的结果中同一级别缺少语义细分的缺点,设计了一种带情景约束和增强语义的相似度计算匹配方法。首先通过服务情景约束兼容性检测过滤掉不相关的服务;然后借助本体进行服务属性间的语义获取和语义相似度计算,得出待匹配服务的精确匹配度;最后对满足用户请求的服务进行反馈评价。实验结果表明,该方法较之传统的OWL-S/UDDI匹配方法在查准率和查全率方面得到了很大改进。
