The essential problem of KBOOA are acquirement and organization of knowledge about the application domain. First of all, we recognize objects according to their outside characteristics and build stable concepts structures. In this way, the attributes and behaviors of any objects are treated as objects as well. The concepts are organized in hierarchies, the concepts' semantics are demostrated in the form of conceptual graphs. As hierarchy structure has inheritance, the system has ability to recognize and reuse concepts, analyze and reason the acquired information according to the existing knowledge, understand the problem space and present the system's functions and characteristics to the analysts and users in the form of scenarios. The main means of transforming informal requirements to formal ones is to recognize objects according to their outside characteristics, recognize attributes according to their functional dependence and describe the semantics of objects, behavior and attribute's relationship's because there is a automatic map from the descriptions of attributes and behaviors to class structures. It is difficult to transfer from OOA to OOD, We disscussed the modularity of Object-Oriented programs according to the principles of software engineering and presented the methods to decrease couplings and increase cohesions, i.
KBOOA以知识的获取、组织为中心问题,首先依据对象的外特性识别对象,并将属性和行为也作为对象处理,从而建立起较稳定的概念结构;KBOOA以层次的方法组织概念,以概念图的形式描述概念的语义,利用层次结构的继承特性,使系统具有识别、重用概念的能力,根据已有知识对系统所获信息进行分析、推理,产生对问题空间的理解,并以想定的形式向分析师、用户展示系统功能、性能,从而构成了一个交互式的,具有一定智能的需求分析环境;依据外特性识别对象,依据函数依赖关系识别属性,用概念图描述对象、行为及属性关联,是将需求由非形式化形式向形式化形式转换的主要手段,使属性及行为描述可向类型结构自动映射,为提高需求分析的自动化程度提供了依据。

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 results showed that the rate of mating disruption was 71.1%-80.7% caused by 150-750 rubber pheromone dispersers per hm 2. The egg numbers were reduced by 79.4%-86.1%, 72.9%-84.7%, 58.3%-65.1% and 58 9% at the treatments of 750, 300-375, 120-150 and 30 rubber dispersers per hm 2, respectively. In large scale disruption demonstrations, numbers of egg masses decreased 82.4% and 73.2% at placements of 60 dispersers per hm 2 in mid season rice seeding paddy and in early season transplanting paddy, respectively.

Therefore, the paper discusses how to resolve it. First, we should change the idea of education and promote the teachers" change from inculcating knowledge to facilitating the development of students. Second, we should improve the teachers" professional development and advance the teachers" change from pure curriculum executants to researcher and constructors. Third, we should emphasize the function of curriculum evaluation to develop education and promote the teachers" change from ultimate and only judge to stimulators of students natural development.
