The system is an on - limits tool system . the embodiment are as follows , the first thing is that the describing method of the parts information can be defined by user , the second is that the basal data can be defined by user also such as cell feature , shape feature , array form , etc , the third is that the relation between the process knowledge of parts group and the information model of parts group can be defined by user , the last is that one engineering database manage the process knowledge , all kinds of basal data , user definition and so on . it realizes not only the abruption between data and program but also the abruption between knowledge and illation 本系統(tǒng)是一個開放的工具系統(tǒng),體現(xiàn)在以下幾個方面: ( 1 )零件信息的描述方法(零件組信息模型)可由用戶定義, ( 2 )基礎數(shù)據(jù)如單元特征、形狀特征、陣列形式等可由用戶自定義, ( 3 )零件組工藝知識與零件組信息模型的關(guān)系可以由用戶自定義, ( 4 )工藝知識、各種基礎數(shù)據(jù)、以及用戶模型定義等都由一個統(tǒng)一的工程數(shù)據(jù)庫來管理,實現(xiàn)了數(shù)據(jù)與程序相分離,知識與推理機相分離。
The most advantage of network education is the network education resources is on - limits and can be shared , so how can make the students find the knowledge they need in the huge and unorderly resources is the primary task to network education . the resolvent is to design the query tools of information using in the network education 網(wǎng)絡教育的最大優(yōu)勢是基于開放、共享的教育資源,因此如何讓學生在海量且紛亂的教育資源中查詢到自己所需要的資料是現(xiàn)在網(wǎng)絡教育發(fā)展的主要任務,而開發(fā)出一種運用于網(wǎng)絡教育領域的信息查詢工具是解決這一問題的核心。
As to systemic function of the adaptive mathematics cai software , except for its teaching , its practicability and flexibility , we emphasize a remarkable character on the adaptation that is realized in the sight of its id . as to its configuration , we integrate the existent platform , where we have em phasized id of adaptive learning environment , which make it flexible and on - limits 從軟件的系統(tǒng)功能上,除了具有教學性、適用性和靈活性外,我們定位軟件最突出的功能特征是適應性,這主要從教學設計的視閾來實現(xiàn)這個功能:從系統(tǒng)結(jié)構(gòu)上,我們集成現(xiàn)有的平臺,注重適應性學習環(huán)境的設計,使得整個軟件開放靈活。
