The second , establishing " huge education " mode to meet with 21centuries education development , which brakes the original education restrict in time and space to meet with people ' s education needs to extent 突破了原有教育结构在时间与空间上的限制，最大程度上满足人民对教育的需求，从横向来看，强调各类教育相互衔接和沟通促进，从纵向来看，这种教育结构要求适应终身学习需要，构建终身教育体系。
Because of combination of the merits of frame and shear wall structure , frame - shear wall structure can be not only satisfied the structural space demand , but also be liable to achieving structural demand . for this reason , the type of structure is popular in our country 钢筋混凝土框架-剪力墙结构，由于其综合了框架和剪力墙结构体系的优点，既能满足建筑空间要求，又易于满足结构要求，因此，在我国得到了广泛应用。
This thesis analyses from following angles why speeding hydroelectric power exploitation is necessary for social and economic sustainable development of sichuan province : first , structure of power and resource of sichuan province requires accelerating hydroelectric power exploitation ; second , abundant water resource is advantageous for sichuan accelerating hydroelectric power exploitation ; third , comprehensive benefit results from hydroelectric power projects demands accelerating hydroelectric power exploitation ; forth , hydroelectric power exploitation stimulates development of other crafts ; fifth , construction of large scale project is beneficial for reducing resource cost of the whole society ; last , the process of hydroelectric power exploitation usually consists of much scientific and technological content 本文从下述几个方面分析了大力发展水电是四川社会和经济可持续发展的必然选择：四川的能源资源结构要求大力开发水电；四川水能资源的优势要求大力开发水电；水电工程巨大的综合经济利用效益要求大力开发水电，水电工程除了发电效益外，一般还兼有防洪、灌溉、供水、航运、养殖、旅游等社会效益，水电站的综合利用可以为社会创造巨大的社会和经济效益，造福一方；水电开发对经济广泛的拉动作用要求大力开发水电；大型水电建设有利于降低全社会资源损耗；水能资源的开发利用过程具有较高的科技含量。
After selecting the elastic component shape suitable for the structure of the machine tool , elementary design is implemented for two kinds of component material : 40crnimn & ly12 . then the analyse of the elastic component stress and strain is completed , and the check of the component age limit and strength follows 本文对弹性元件进行了选型和设计，根据机床结构要求确定了弹性元件的形式后，针对两种常用的弹性元件材料( 40crnimn和ly12 )进行了初步设计，然后对弹性元件进行应力应变分析，并对弹性元件进行了强度和寿命校验。
Based on the requirement for the information cadre , the author establishes the system architecture , and analyzes function construction , network construction and security of the system . and then , based on the introduction of the theory of ahp ( analytic hierarchy process ) , the author establishes the ahp model of the system . then the author establishes a archetypal system of bidding system of procurement online based on windows . in the end , after the sum - up of the whole paper , some further researches are suggested 在分析系统对信息基础结构要求的基础上，建立了系统的体系结构，分析了系统的网络架构、功能结构和系统的安全处理策略；在介绍层次分析法理论的基础上，建立了中标评定子系统的ahp模型，并给出了ahp算法的计算实例；开发了基于windows的网上采购招标原型系统，并介绍了系统的运行界面。
It furnishes tri - step configuration of analyzing economic elements in the international investment to large - scale construction : firstly , how the economic elements configuration meets the demand of international investment ; secondly , analysis of project location ; thirdly , analysis of project economic benefit with foreign investment 本文提出了大型土木工程国际投资所需完成的经济因素分析三步结构：国际资本本身对经济因素结构要求的分析，项目地域经济因素结构的分析和国际资本进入当地的经济效益结构的分析。
By using diffusion welding method ( under certain welding parameters such as temperature , pressure , time and atmosphere , etc ) and employing rational structural control technique , a kind of 93w - ofc - tc4 - a1 - mb2 system flier - plate with good parallelism , planeness and high densification was prepared , which met the needs of initial design and the basic requirement of flier - plates 利用平面扩散焊接法(控制一定的温度、压力、时间、气氛等条件) ，同时采取合理的结构控制方法，成功实现了93w - ofc - tc _ 4 - al - mb _ 2的整体连接，得到了平面性好、平行精度高、整体致密的波阻抗梯度飞片，满足了设计结果和梯度飞片的基本结构要求。
