查询词典 difficult problem

China Engineering and the teaching has yet to fully utilize the power of MATLAB, MATLAB existing books mostly as a computer application tool there, not with the specific disciplines of organic materials combined, MATLAB GUI interface design, will be teaching content according to a certain order of the structure, using simple language, a rich display screen in front of the students. not only improes the students interested in this program, also makes some of the more abstract concepts of the past and the process of teaching students to reflect difficult to understand and master the content, through iid, image of the method explained to the students, so that students more easily understand and grasp. MATLAB and the emergence of soling this problem, MATLAB based on its powerful calculation and graphics functions so as to sole the problem, The system is controlled teaching address the dull, abstract characteristics do.

而我国工科类的教学还未能充分利用MATLAB的强大功能，现有的MATLAB书籍大都作为计算机应用工具书出现，未能与具体学科的教材有机地结合起来，MATLAB中的GUI界面设计，将教学内容按照一定的结构顺序，用简洁的文字、丰富的画面展现在学生面前，不仅提高了学生学习本课程的兴趣，还使得一些比较抽象的概念和过去教学过程中学生反映难以理解和掌握的内容，通过生动、形象的方法向学生阐明，使学生更容易理解和掌握，而MATLAB的出现解决了这一问题，MATLAB基于它强大的计算和绘图功能从而解决了这一问题，本系统就是针对解决控制教学中的枯燥，抽象的特点而做的。

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。
