摘　　要：以＂2010年中国上海网上世博会＂为研究背景,针对网页中用户在线拖动搭建虚拟展览馆的动态生成和个性化定制要求,从虚拟展览馆的组件特征、数据构成和应用网络方面进行了分析,提出了以具像特征体描述为原则的组件化拆分方法,建立了基于基因特征的展览馆组件编码规则和B/S架构下的二次检索机制,由实验导出了组件传输时间和场景构建响应速度的关系及优化方法。通过应用于网上博览会在线拖动搭建系统,证明了该方法有效解决了网页中动态构建虚拟展览馆的元素组合和重构问题。Under the background of＂Expo Shanghai Online 2010＂,this paper analyzed components features,general building interfaces and the application network of virtual pavilion for the demands of dynamic generation and customization of virtual pavilions which were built by user online in drag-and-drop way. Presented a splitting method on the principle of figurativecharacteristic description of 3D object and established gene characteristic code rules of components as well as the secondary searching method based on B/S architecture. Exported the relationship and optimization of components transmitting time and responsiveness by experimentation. Using the method in drag-and-drop building system on virtual exhibition online,the validity of solving the problems that elements combined and reassembled is proved.
