The dissertation presents a new design approach of hierarchy optimization to design the crossbeam . the layout optimization of structure is carried out to get a comparatively reasonable primary conceptual design . the conceptual design is modified according to our experience to answer for the practical situation 以这两种概念结构为模型,结合工程实际情况设计了初始方案的两种横梁结构,找到对横梁结构影响最大的载荷位置,并对此载荷位置的横梁进行结构参数优化。
The data and the function requirements for this database system are deducted firstly by the analyzing of the data flow fig and the compiling of the data dictionary . then , the local e - r fig and the whole e - r fig are obtained by concept structure design . the database physical design is finally completed by sql server 2000 and the whole structure of the database is built 首先通过分析系统数据流图，编写数据字典，得出数据库系统的数据和功能需求；然后经过概念结构设计得到数据库局部e ? r图和全局e - r图，经过逻辑结构设计将e ? r图转换成关系数据模型；最后采用sqlserver2000作为工具完成了数据库的物理设计并建立了数据库的全部结构。
According to the modern education theory , we should adopt the following tactics in teaching the concept of chemistry : 1 . use the vivid visual image to let the students gain the knowledge of the concept ; 2 . create the atmosphere and let the students take part in the formation of the concept of chemistry ; 3 . revise the old knowledge while learning the new one to realize the assimilation of concept ; 4 . proceed step by step , lead the students deepen and develop the concept ; 5 . give prominence to the understanding of the key words of the concept , get deeper understanding ; 6 . pay attention to the relation between the concepts ; 7 . optimize the study strategy and enhance the cognition standard , i . e . in the teaching of the concept of chemistry , we must pay great attention to the usage of various kinds of teaching method , including visual experiment , visual language and cai courseware , in order to help the students to understand the concept ; use the question to stimulate students " thoughts , give free rein to students " corpus , and let the students take part in the teaching process actively ; guide the students to remember new concepts and the help of their old knowledge ; pay attention to the levels of the concept , deepen and develop the concept continuously , use various ways to strengthen the meaning of the key words , help the students to master the concepts connotation , and give a clear extension , guide the students to found the concept system 也就是说，在化学概念的教学中，要注意充分运用各种直观教学手段，包括实验直观、语言直观和cai课件直观，帮助学生理解概念；注意运用问题启动学生思维，发挥学生的主体性，使学生积极参与教学过程；要指导学生利用原有认知结构中适当的概念图式来学习新概念；注意概念教学的层次性，不断深化和发展概念；注意通过各种方式强化概念中关键字、词的意义，帮助学生准确把握概念的内涵，清晰界定概念的外延；注意引导学生在应用中建立概念系统，形成合理的概念结构。同时在概念教学中还要注重学习方法的传授和学习策略的形成，进行适当的元认知训练，优化学生的学习策略，提高其元认知水平。根据化学概念的教学策略，化学概念的基本教学程序为:创设问题情境，引入概念;组织问题解决，建立概念;引导知识整理，概念系统化;指导练习应用，概念具体化。
O conceptual hierarchies organization technique concepts in databases are organized into a partial order called conceptual hierarchies . conceptual hierarchies play an important role in the knowledge discovery process because they specify backgroud or domain knowledge and may affect the discovery processing and the results . ln this paper , basic ideas about conceptual hierarchy and its manipulation are discussed . based on the conceptual hierarchies in the nms database , we present processing methods o application research of multilevel association algorithm in the nms database we emphatically discuss performance data multilevel conceptual association problems on network management background , especially , the association between performance data and geographic location . after studying encoding multilevel association algorithms and background item constraint algorithms , an efficient mining multilevel association algorithm between performance data and geographic location is presented . lt is efficient for mining useful association rules 一旁多级关联算法在网络数据库中的应用本文重点研究了网络管理背景下多级概念下性能数据关联问题，特别是性能数据和地理位置关联的问题。将概念结构方法应用于网络管理数据库之中。通过对编码结构实现的多级关联技术的研究，通过对网络管理数据库下背景知识约束条件实现研究，提出了”一种高效的，网络管理性能数据与地理位置关联的挖掘算法。
In this article , the author firstly introduce the conception of amc corporate governance and the successful experiences of rtc in america , then go deeply into is where the problem is about amc corporate governance in our country , at last further advance the optimal and second - best strategy to optimize corporate governance of amc in the end 本文先从金融资产管理公司法人治理结构的概念结构和美国rtc的成功经验入手，进而深入分析了我国金融资产管理公司法人治理结构的缺陷所在，最后提出了优化我国金融资产管理公司法人治理结构的最优策略和次优策略。
In the second part of this article , with analysis of the system engineering , software requirement and acceptability for the management information system , author has finished definition structure design , logical structure design and physical structure design of the database with asa6 . 0 of sybase company , and got the corresponding definition structure and logical structure models . in the environment of pb7 . 0 , designed the relation of models , detail of every model and coding them , completed the interface of this system and the function of every model 本文第二部分通过对边坡信息管理系统的系统分析、需求分析和可行性研究，在sybase公司的asa6 . 0数据库环境下，对边坡信息数据库进行了详细的概念结构设计、逻辑结构设计和物理结构设计，得出了相应的概念结构和逻辑结构模型；在pb7 . 0的编程环境下，对系统做了相关的总体设计和各模块的详细设计和编码工作，完成了整个系统的用户界面和各模块功能的实现。
To goal design , systematically develop background , developments and running environment choose , systematic function analyse , systematic function module design , data base demand analyse , data base concept structure design , structure design , data base structure realize logic , , systematic functions finish realizing function the establishments of modules each course gone on detailed description data base 对目标设计、系统开发背景、开发和运行环境选择、系统功能分析、系统功能模块设计、数据库需求分析、数据库概念结构设计、数据库逻辑结构设计、数据库结构实现、各个功能模块的创建、系统功能实现等各个过程进行了详细的描述。
Regard construction of the structural frame system of the concept of strategic management accounting as the main content studied , proceed from construction principle of the structural frame of the concept of strategic management accounting , this paper structures the frame mode of the logic starting point which regards goal of strategic management accounting as the concept structure basic content system of strategic management accounting , and analyze systematically to every key element of basic content of concept structure of the theory of strategic management accounting at the same time 摘要本文以战略管理会计概念结构框架体系的构建为研究的主要内容，从战略管理会计概念结构框架的构建原则出发，构建出以战略管理会计的目标作为战略管理会计概念结构基本内容体系的逻辑起点的框架模式，同时对战略管理会计理论概念结构基本内容各要素进行了系统的分析。
In order to solve these problems mentioned above , this paper proposes a course conceptual model ( ccm ) , which is derived from traditional course ’ s conceptual structure and its instructional strategy , and put forward a formative description of ccm in three aspects : instructional objective , course conceptual tree and relations of knowledge points ( kp ) 针对以上问题,本文通过对传统教育模式中课程概念结构及其教学策略进行抽象,从教学目标、课程概念树和知识点关系三个方面给出了课程概念模型的形式化描述。
