查询词典 virtual image

There are three problems that should be deliberated when constructing a typical distributed virtual environment: 1 the representation of complex model in virtual environment, usually there are many entities and data in environment that should be recognized carefully. 2 the network communication, update and synchronal information is needed for variable entities are distributed in different computers linked by network. 3 the controlling of participant's behavior.

一是复杂模型的表达，通常这样的系统中包含复杂的较大规模的场景数据以及为数众多的实体，需要对这些实体加以组织；二是网络通信，由于环境中存在诸多可变因素，需要通知其它节点机做相应的刷新和同步，同时，分布的计算单元之间也需要交换消息或数据；三是参与者行为的控制。

It provides a real case and has analysed the knowledge type in virtual enterprise and the knowledge flow in virtual enterprise; put forward the influence factors that may cause the alliance to stop, the ones that ascribed its basic reason is unsmoothness of knowledge transfer. At last, according
