【摘要】 随着教学体制的改革，实验成为教学环节中不可缺少的重要组成部分。但许多高校实验室存在教学设备陈旧、教育资金不足的问题，难以满足日益增长的学生的需求。因此，通过网络和虚拟的实验操作环境进行实验教学尤为必要。针对电路分析实验来说，繁多的实验器件和复杂的实验操作环境是必不可少的。随着虚拟现实技术的应用和发展，实现一个网络化的电路分析实验系统有着广泛的应用前景。针对以上问题，本论文通过分析、比较国内外流行的电工电子虚拟实验软件器件库的解决方案，提出并实现了一个基于Web的、针对电路分析实验的电路实验虚拟元器件库的集成开发环境。服务器端采用Java的Servlet技术，利用PSpice软件作客户端请求的电路分析解决方案，组件库实现了电阻、电容、电感、晶体管、电压源、电流源等基本的元器件，电流表、电压表、MOS场效应管和集成运算放大器等复杂的电子器件。不同的组件可存入不同的组件库中，在进行电路实验时可从多个组件库中分别提取组件并完成实验。本课题所开发的组件库系统具有良好的扩展性，支持动态定制并扩充虚拟元件，用户可以利用系统提供的组件库配置功能动态增加、删除元件或改变元器件的属性，方便用户使用与维护。更多还原

【Abstract】 With the development of education, experiment has been an indispensable part of teaching. But the laboratories of many high schools have the problems such as old experimental equipments and lacking of financing, and can not satisfy the need of the expansion of enrollment currently. So, it is necessary that achieve the experiment education standards by network and virtual experiment environment. Especially in circuit analysis experiments, various experimental apparatuses and complicate operation environment are indispensable. With the application and development of the virtual reality technology, it will have a good foreground to complete a virtual network circuit analysis system.To solve the above problems, through the analysis and comparing the prevalence of Electrical and Electronic Virtual Experimental Software Components of the solution, this paper has brought up and achieved a web-based virtual integrated development environment of components which is against Circuit Analysis experiments. The solution of the server is using Java Servlet technologies and PSpice software to analysis the requests from client. The components library has designed those basic components such as resistors, capacitors, inductors, transistors, voltage source, Current sources, also including some complex circuit devices such as MOS transistor and Integrated Operational Amplifiers. Different components can be deposited in the different component library and user can select different needed components from different.The Components Library of this paper has good expandability, which support dynamic customization and the expansion of virtual components. Users can use the dynamic customization provided by this system to add components, delete components or change component’s properties. So it is easy to use and maintains.更多还原
