摘　　要：针对传统CBT(计算机支持的教育培训)系统用户单一、沉浸感不强、不支持协同学习等问题,提出协同虚拟环境支持下技能训练系统的实现方案.采用分层结构思想,设计系统的框架结构和工作流程;提出基于模型复杂度的快速建模策略,构建协同虚拟训练场景;利用并发服务器通信技术,构建多用户协同工作环境;采用定时采集和发送数据的方法,降低协同感知过程中服务器的负担;结合矢量化电子图板和文字消息传递机制,满足教师实时评注和多用户讨论的需求.结合应用实例,验证了本方案的可行性和相比传统CBT的优越性.This paper puts forward the realization of collaborative virtual environment assist in skills training system against on the CBT（computer based training） systems, which contains the problems of single-user, lack of immersion and no collaborative learning is assisted. The system designs system framework and workflows base on stratified structure idea. It proposes a rapid-modeling strategy based on model complexity to build collaborative virtual training scenarios. It uses mult-communication server technology to build the multi-user collaborative work environment. It reduces the burden of server in collaborative perception process by timing acquisition and sending data methods and meets the needs of teachers＇ real-time commentary and multi-user discussions by vector electronic drawing board and text messaging mechanism. It verifies the feasibility and superiority between the new system and traditional CBT by application examples.
