as for the peculiarity of strong practicality and operationality of computer courses, we should instruct students to learn to study while doing and learn to do while studying, and let them understand and acquire knowledge with the computer's unique advance 摘要針對計算機課程具有實踐性和操作性強的特點,我們要引導學生學會“做中學,學中做”,并以其獨特的先進性讓學生去自悟、自得。
in view of uncertain factors of an enterprise's loyalty to its staff, this paper applies the conception and methods of fuzzy mathematics to set up a model with many levels of fuzzy evaluation, which has great practicality and operationality, and can give some guidance to an enterprise 本文針對企業(yè)對員工忠誠存在的不確定因素,應(yīng)用模糊數(shù)學的概念和方法,建立了企業(yè)忠誠度的多層次模糊評價模型,該方法具有較強的實用性和可操作性,能夠?qū)ζ髽I(yè)起到一定的指導作用。
in rup, use cases drive whole core work flow, that is . from reqirement capture . through analysis . design and implementation to test . among these, use case analysis technology carries out the following process : firstly, capturmg system's function requirements . developer builds structural requirement model ( use case model ), secondly, identifying class from use case, developer builds class diagram . use case analysis technology can instruct the process of building class diagram, but a fatal shortcoming exists in itthat is, the process of identifying class is easily involved in function decomposing method . and its operationality is limited 該方法中的用況驅(qū)動完成了rup中一整套核心工作流(從需求捕獲,經(jīng)由分析、設(shè)計和實現(xiàn),到測試),其中用況分析技術(shù)完成的工作是從捕獲需求入手,建立結(jié)構(gòu)化的需求模型(用況模型),進而從用況中識別類以得到類圖。這種技術(shù)對建立類圖有一定的指導意義,但有一個致命的缺點,即隨著類識別的深入易陷入功能分解法的誤區(qū),而且其可操作性也不是很強。
