集中在...上

Empirical evidence on the relationship between "tunneling" and earnings management suggests that,"tunneling" would decrease the transparency of the whole economy, and then decrease the capital allocation efficiency of capital markets, finally delay the economic growth. Under the conditions that investor protection is very poor and ownership is concentrated, listed companies in Chinese stock market are always agencies of controllers to get private benefits at the expense of minority shareholders.

正出于此，本论文以我国股票市场特殊的制度背景为出发点，在参考Bebchuk（1999）模型的基础上，发展了一个理论模型来证明，在投资者保护薄弱和所有权集中的制度背景下，控股股东具有充分动机来侵占少数股东利益获取控制权私利。

In 1962, Peter Drucker, the famous master of economics and management, presents definitely that logistics was the last area for decreasing cost in his paper Economy"s Dark Continent published in fortune. For 40 years, the concept of logistics was expanded continually and more and more attentions were paid on it. Especially from middle of 1980"s to this day, with the increase of economic globalization and development of the information technology, more and more enterprises go back to their main businesses, and pay their points on these businesses such as product development, manufacture, marketing, which are their core businesses and they are good at. These businesses embody the competitive advantages of the enterprises.

1962年著名经济管理学大师彼得·杜拉克在美国《财富》杂志上发表《经济的黑暗大陆》一文，首次明确地提出物流是节约成本的最后领域。40年来，物流的概念在不断地拓展，人们对物流管理越来越重视，特别是80年代中期至今，随着经济全球化竞争的加剧、信息技术的飞速发展，许多生产企业回归主业，将精力集中于产品开发、生产、销售等具有竞争优势的核心专长业务的呼声日益高涨，理论界和企业界已不再浅层次的探讨物流管理的重要性问题了，他们开始探讨物流管理的模式问题，即：究竟是自营物流业务，还是将物流业务外包给专门从事物流管理的企业去做。

He is trying to decentralize the vastest concentration of industry the world has ever seen by establishing small accessory plants in rural districts where workers can live on the land.

他正在尝试把世界上最大的集中工业厂区拆散，在郊区建立小的零配件加工厂，好让工人们住在附近。

In chapter three, with the effective combination of the prior preference, posterior preference and interactive method, and based on the theory of satisficing decision making and goal programming, an interactive method for solving static or dynamic multicriteria programming is devised. In the method, by constructing the simplexes in the set of parameters and transforming them, the local preference information is interactively quested in th process of decision making. The prior and posterior preference are used to speed up the process of decision making and overcome the false convergency which may be occured in pure interactive algorithms. This method can be used to cope with linear, nonlinear and dynamic multicritcria programming.

在第3章多目标数学规划的参数单纯形方法中，通过多目标数学规划的验先偏好方法，交互式方式与验后偏好方法的有效组合，在满意决策和目标规划的理论基础上提出了一种求解多目标静态及动态规划的交互式方法，该方法通过在参数集中构造单纯形并进行其变换，在决策过程中交互地索取决策者的局部偏好信息，并利用决策者的验先偏好来提高决策过程进行的速度，及利用决策者的验后偏好来克服纯交互式算法中可能出现的假收敛现象。

The results show that space finite analysis results are close to test ones, bottom chords suffer axial force and large in-plane bending, and the max stress is nearby each middle internode. The max stress of node crossbeams occurs in No.2 bottom flange, and that of internode crossbeams happens in ones lying in the middle of every internode. The concrete slab is in tension at the longitudinal direction, and also suffers bent at vertical loads. The degree of completely-composite model taking part in the combined actions is about 55%, while that of semi-composite model is 42%-43%. The combination of concrete slab and bottom chord increases the degree of floor system taking part in the combined actions, lightens the burden of bottom chord, and reduces out-of-plane bending of node crossbeams especially the ones near bridgehead. Stress and displacement of main truss can be evaluated by a equivalent plane rigid frame in preliminary design, and effective stiffness of bottom chords are composed of original ones and concrete slab, and the concentrated load from deck can be translated into uniform load.

研究结果表明：空间有限元分析结果与试验结果较吻合；下弦杆受到轴向拉力和较大的面内弯矩作用，各节间最大应力出现在节间中点附近；节点横梁最大应力发生在横梁2的下翼缘，节间横梁最大应力发生在位于端节间中部的小横梁上；混凝土板顺桥向整体受拉，并在竖向集中荷载作用下产生弯曲变形；全结合模型大部分节间内的桥面板参与主桁共同作用的程度为55%左右，半结合模型桥面板的参与程度为42%~43%；桥面板与下弦杆结合能够增加桥面板的参与程度，减轻下弦杆荷载，减少节点横梁尤其是靠近桥头横梁的面外弯曲；对桥梁进行初步设计时，主桁杆件的位移与内力可按照1个等效的平面刚架计算，下弦杆的等效刚度由原下弦杆截面和混凝土桥面板截面组合而成，桥面荷载可转化为均布荷载施加。

The details d are following:1 Try to development social swimming sport, especially primary school and middle school swimming sport, so as to present wide base for talent selection.2 According to the geographical environments and swimming traditional of Vietnam, the key development area of competitive swimming is the following city , northern part of Vietnam:Ha Noi, Hai Phong, Quang Ninh, Thai Binh, Nam Dinh; mid-part of Vietnam:Thanh Hoa, Quang Binh, Da Nang, Binh Dinh; southern part of Vietnam: Ho Chi Minh, Long An, Vinh Long, Ben Tre. So it should establish national key swimming center in the above-mentioned city.3 Vietnamese organization concerning swimming sports should attach more attention to and organize specialist, experience coach to develop applied science research, so as to obtain more greater achievement in talent selection and scientific training.4 It is important for Vietnam to concentrate all of swimming specialist to organize national training committee, which is in charge of researching and establishing training program for every age stage, meanwhile it should direct swimming centers to implement this program.5 In order to promote the quality of swimming coach, national sports bureau and under-water sports association must establish'coach hierarchy system'.6 It is essential to improve the quality of sport team management. Currently, we must set up uniform scientific management goal and task, i.e. to improve the management ability of swimming coach.

相应的发展策略为：1努力发展群众性游泳运动，尤其是在儿童少年的各中小学学校的游泳运动，为科学选材提供更广泛的选材基础。2根据越南的地理环境和各地游泳转统在竞技游泳的重点发展地区的布局应该是在越南北部各省市：河内、海防、广宁、太平、南定，越南中部各省市：清华、广平、蚬港、评定，越南南部各省市：胡志明、龙安、永龙、槟蜘上面的各省市设为全国的重点游泳中心3越南游泳各层组织要重视和有计划地结合全国游泳学者、各项体育学者、有经验教练员开展应用科学研究，使得在选材工作和科学训练工作等获得更高的成效。4越南应集中全国的游泳专家、科学家成立国家训练委员会，负责研究和制定出各年龄组的科学训练大纲，同时指导全国各游泳中心统一使用。5为了能促进教练员更快的提高本身素质，国家体委和水平运动协会尽快制定&教练员等级&制度。6增强、提高运动员队的管理工作质量、目前要立即制定统一的科学管里目标和对教练员明确管理任务既提高教练员的管理能力。
