第50届世乒赛松平健太技战术特点分析

运用文献资料法、三段技术统计法、录像观察法,对2009年第50届世界乒乓球锦标赛日本年轻选手松平健太对马琳、卡拉卡塞维奇的两场共11局比赛进行技战术统计和分析,结果表明：下蹲砍式发球是松平健太最强的技术,其次是正手住拉斜线和反手位拉斜线,正手位和反手位的防守是他的弱势技术。     

苦竹亚族的修订

This paper deals with the taxa of tribe Arundinarieae Steud. subtribe Pleiobalastinae Keng and Keng f. which comprised three genera (Pseudosasa Makino, Pleioblastus Nakai and Brachystachyum Keng) when it was established in 1957. With the analysis of morphological characters and geographical distribution, a number of revisions connected with the taxon are made as follows:      (1)  Genus Brachystachyum Keng is transferred to the tribe Shibataeeae Nakai ac- cording to its false inflorescence.      (2)  Genus Pseudosasa Makino is transferred to subtribe Sasinae Keng f. according to our study on the numerical taxonomic method.      (3)  Some species of Pleioblastus Nakai established by Keng and Keng f. should be revised. Pleioblastus actinotrichus (Merr. and Chun) Keng f. should be Ampelocalamus actinotrichus (Merr. and Chun) S. L. Chen, T. H. Wen and G. Y. Sheng in subtribe Tham- nocalaminae Keng f.; Pleioblastus dolichanthus (Keng) Keng f. is the synonym of Sinobam- busa tootsik (Sieb.) Makino, belonging to tribe Shibataeeae Nakai. The rest species remain in this genus. Since the genus Pleioblastus is related to genus Arundinaria Michaux., subtribe Pleioblastus Keng and Keng f. does not seem to have a reason to be retained as a subtribe in tribe Arundinarieae Steud., according to the newest Code (1978). A part of it should be a synonym of subtribe Arundinariinae and we may cite it as follows: Subtribe Arundinariinae——Subtribe Pleioblastinae Keng and Keng f. pro parte, syn. nov. The other parts of it should be transferred to other subtribes or tribes.       In addition, one new variety in Branchystachyum, two new species, one new variety in Pseudosasa and six new species, three new varieties in Pleioblastus, are described in this paper.     

Passive fuzzy controller design for nonlinear systems with multiplicative noises

This paper proposes a passive fuzzy controller design methodology for nonlinear system with multiplicative noises. Applying the Itô's formula and the sense of mean square, the sufficient conditions are developed to analyze the stability and to design the controller for stochastic nonlinear systems which are represented by the Takagi-Sugeno (T-S) fuzzy models. The sufficient conditions derived in this paper belong to the Linear Matrix Inequality (LMI) forms which can be solved by the convex optimal programming algorithm. Besides, the passivity theory is applied to discuss the effect of external disturbance on system. Finally, some numerical simulation examples are provided to demonstrate the applications of the proposed fuzzy controller design technique.     

控制权激励的约束条件研究

控制权激励作为一种隐性激励方式是我国经营者弥补显性报酬不足的重要手段。在委托—代理理论的分析框架下,从内部治理机制和内、外部治理机制共同作用两个方面建立了控制权激励的约束模型,分别求出了两种情况下经营者增加控制权行为的最优解。模型说明,随着企业内、外部治理机制的逐步完善,控制权激励的作用将逐渐减弱,企业应从显性激励的角度来完善经营者激励机制。

辽宁产业结构与就业结构协同性实证研究

产业结构性矛盾一直是困扰辽宁经济发展的核心问题.经过30年的结构调整,辽宁产业结构演进呈现"三产化"趋势,但就业结构"非农化"进程缓慢,三次产业的结构偏离度比较大,产业结构与就业结构之间存在着十分突出的矛盾.辽宁老工业基地全面振兴,应兼顾"经济增长"与"充分就业"两个目标,提高结构变动的协同性.     

温州民营企业集群与技术创新模式研究

改革开放以来,温州民营企业依赖渐进型创新取得了竞争优势。但是,由于渐进型创新潜力的耗尽,以及重大创新与基础性创新的缺乏,温州急需从依赖渐进型创新转向突破型创新。本文在总结温州民营企业技术创新模式基础上,研究温州企业的渐进型创新与企业集群模式的相互强化,提出培育温州民营企业重大创新和自主创新能力的政策建议。     

统筹城乡发展体制机制的创新与实践——以浙江省为例

浙江统筹城乡发展战略的实施,关键得益于在总体战略构想及体制机制的创新实践,其特点主要表现为：科学建构统筹城乡发展、推进城乡一体化的目标体系;不断完善统筹城乡发展、推进城乡一体化的制度框架;逐步优化统筹城乡发展、促进城乡一体化的机制模式,从而形成了具有浙江特色的政府为主导、农民为主体、社会力量协同参与的动力机制和运行模式。     

用VB.NET实现基于案例的知识管理系统

系统基于Windows平台,使用VB语言在微软.NET框架下完成,设计并实现一个基于"非规范用词"和"典型案例词典"的文本分类系统,系统采用人脑对自然语言理解的心理学原理"人们总是根据已知的最熟悉的、最典型例子的进行判断,只有在该方法不奏效的时候才使用频率这一概念,并且使用的是十分简单的频率"的分类策略。详细介绍词语切分统计、词库设计、父类词匹配、子类词匹配等子系统模块。     

我国文献计量学中作者问题研究现状分析

文献计量学中作者研究受到极大地关注,相关文献呈现出快速增长的趋势,系统地分析我国此类研究的现状,对于进一步研究和实践具有重要的现实意义。本文运用文献计量分析方法对1999-2008年文献计量学中作者问题的研究的文献从数量和增长、分布情况、作者群和研究主题等进行分析,试图通过研究历史和现状,为未来作者问题的发展奠定基础。
