【摘要】 目前远程虚拟实验开发远远不能满足远程教育的需求,其中重要的原因之一就是远程虚拟实验设计时缺乏统一的系统模型。首先给出了虚拟实验的形式化定义;其次利用面向对象方法,应用UML建模语言为远程虚拟实验过程建立了完整的模型,包括其用例图模型、静态模型,以及用活动图和系列图表示的动态特性。通过这些抽象模型,明确了虚拟实验对象、虚拟实验操作,以及协作、过程迁移等概念之间的关系。虚拟实验过程模型的建立,为远程虚拟实验的高效和定制化开发提供了基础。更多还原

【Abstract】 The development of distant virtual experiment does not meet the demand of modern distant education up to now.One of the main reasons is that distant virtual experiment process model is not built up.The formalized definition of virtual experiment is given,and an abstract-formal model of virtual experiment process is built up by applying object-oriented technology and UML,including use case diagram,static model,and dynamic model by use of active diagram and sequence diagram.The relationships between these concepts as virtual experimental object,virtual experimental operation,collaboration,processing transition are clarified.The study provides the foundation to implement efficiently customized development of virtual experiment systems.更多还原
