RIA ( Rich Internet Application) has been developing rapidly in recent years. It has many advantages. Adobe Flash Builder is particularly so advantageous that it is widely used. The design uses Flash Builder (abbreviated as FB) as the client to achieve front design of virtual lab and achieves the save and open operations of circuit design; it integrates FMS ( Flash Media server) to design an online chatroom for technology exchanges among users; it utilizes a software, XAMPP, to realize networked virtual lab and user management; by theoretical research and detailed design, it realizes the full interactivity of digital circuit virtual lab. Compared to either half-interactive or stand-alone virtual labs, the experimental platform is obviously superior at human-machine interactivity effects and application promotion so that the diversification and informatization of teaching methods is promoted.%RIA(富互联网应用)近几年得到了迅速发展,并具有诸多优势,特别是adobe公司的开发的flash builder最具发展优势,并得到了广泛应用.提出以Flash Builder(简称FB)为客户端实现虚拟实验室的前台设计,并实现电路设计的保存和打开;结合FMS(Flash Media server)设计在线聊天室,便于用户技术交流;以集成软件XAMPP实现虚拟实验室网络化和用户管理;通过理论研究和具体设计,实现数字电路虚拟实验室的全交互式.与半交互式和单机版的虚拟实验室相比有明显优势,此实验平台实现了更好的人机交互效果和便于应用推广,促进了教学手段的多元化和信息化.
