中文摘要：

将传统的面向互联网的协同虚拟环境（CVE）同移动技术相结合，发展了新型的协同虚拟环境——混合协同虚拟环境（混合CVE）。混合CVE是典型的异构系统，针对这一特点，提出了使用计算转移和存储转移对异构环境进行平衡的策略，并提出了移动终端的实时通讯、异构三维引擎协同、场景管理和一致性维护等关键技术的解决方案。最后使用Java语言开发混合CVE的原型系统，测试结果表明，异构终端的协同具有实时／准实时性，证明了混合CVE在技术上可行。

英文摘要：

A new type of collaborative virtual environments （CVE）, called mixed collaborative virtual environments （MixedCVE）, was proposed. Mixed-CVE extends traditional Intemet-oriented CVE to mobile network. Mixed-CVE is typically heterogeneous. New strategies of computation transfer and storage transfer from mobile clients to servers were proposed, to make balance between different networks and different terminals. Key technologies including mechanism of real and long time communication on mobile terminals, collaboration between isomerous 3D engines, and scene consistency maintenance between different terminals were proposed to make Mixed-CVE more efficient. A prototype was then implemented in Java. The results showed that collaborations in the system were real-time/quasi-real-time, which proved that Mixed-CVE is feasible in technology.
