摘　　要："和欣"嵌入式操作系统是基于CAR构件技术、支持构件化应用的操作系统。浏览器在"和欣"网络编程模型中扮演着重要的角色,将成为"和欣"操作系统的主要客户端,为用户提供服务。分析目前主流的浏览器的系统结构,同时借鉴国外一些浏览器开源项目,提出了适合和欣操作系统的基于浏览器模型的图形系统体系架构。该架构具有模块化、可定制行为、方便扩展的特性。它包含数据处理、布局、显示、网络等基本功能模块,还抽象出了文档对象树模块。利用文档对象树进行页面元素的管理,有效简化了系统的开发,并提供了良好的扩展性。Elastos is an embedded operating system based on CAR component technology and supporting the component application. Web browser plays an important role in the network programming model and it will become the main client of the Elastos providing services for the customers. Studies current browser system structure and refers some foreign open source project. It proposes a new frame based on browser model. This frame has the character of modularization,configuration and extend. It contains data -- proeexsing, layout, displaying modules,it also contains document object tree module. It manages page elements by document object tree and simplifies the developing of the system and provides the favorable extend.
