【摘要】 继传统因特网、web之后，网格成为当前高性能计算方面研究的一个热点问题，被科学预言家们称为下一代计算机网络基础。它是高性能计算机、分布式技术、因特网等几种技术的有机组合和发展。简单地讲，传统因特网实现了计算机硬件的连通，web实现了网页的连通，而网格试图实现互联网上所有资源的全面连通和共享，包括计算资源、存储资源、通信资源、信息资源、知识资源等等[48]。 网络的发展离不开网络使用模式的研究。本文分析了网络使用模式的发展历程和趋势，重点对当前流行的客户机／服务器使用模式和基于web的B／S使用模式进行了分析和探讨，在此基础上根据网格自身的特点，分析了在网格中的使用环境的需求和特点。 网格Portal是网格使用环境的重要组成部分之一，本文结合国内外最新的发展技术，提出了一种新型的网格Portal体系结构，它能满足网格中使用环境的需求。 当然，由于国内外对网格技术的研究还处于起步阶段，网格使用环境的研究还存在许多亟待改进之处，本文最后对网格Portal的下一步工作进行了说明和展望。更多还原

【Abstract】 The Grid technology is a hotspot in HPC research after the conventional internet and web, which is called the next network infrastructure. The Grid technology is primary combination and development of many technologies, such as high perform computing, distributed technology ,intemt and so on . It is said simply that the traditional internet implement the connection of computer hardware, web implement the connection of page and the grid tries to implement the thorough connection and sharing of all grid sources, such as computing sources, storage sources, Communication sources, information sources, knowledge sources and so on .The development of network is builded on the research of the using mode of network. This paper describes the development and the trend of the using mode of network, and discusses the using mode of popular client/server and browser/server, which is based on web. And analyze the character and demand of the grid using environment based on above analysis and the grid’s character.Grid portal is an important part of grid. Based on new development of grid technology this paper presents a new architecture of grid portal, which could meet the requirment of grid using environment.Of course , there is much improving in the research of grid using environment because the research of grid is under the way. Finally , we present the next work of this grid portal.更多还原
