【摘要】 随着计算机网络的发展,远程教学正在成为一种重要的教育模式。网上协同虚拟实验室的出现,使远程教育更趋完善,它的建立大大提高了实验教学的伸缩性和适应性。该文设计了协同虚拟实验室的一种基本框架,论述了协同虚拟实验室应具有的基本功能,提出了协同实验中的并发控制策略,最后指出了协同虚拟实验室设计中用到的其它关键技术:人机交互技术、群体感知技术、组播技术等。更多还原

【Abstract】 The distance learning is becoming a sort of important education model as the result of computer network development. The distance cooperating Virtual Lab is necessary for a perfect distance education, it expands range and application in experiment education. The paper designs a basal architecture of cooperating Virtual Lab, discusses some functions of cooperating Virtual Lab such as, presents a sort of concurrency control strategy in cooperating experiment, shows some key technologies of cooperating virtual lab such as Human Computer Interactive technology, the awareness mechanism, model of group multicast and so on.更多还原
