摘　　要：在网格计算环境下,如何解决其中的关键技术是实现一个高效快速网格的重要因素。文中对现有的网格结构进行了分析,指出了五层沙漏结构的特点,以及OGSA模型的一些优点,在此基础上比较了它们的异同;任务的协同是网格计算的核心,要解决好此问题,主要涉及到5个关键技术,文中对此进行了详细地分析;同时3种资源管理模型———层次模型、抽象所有者模型和经济/市场模型也是一个不可或缺的方面,文中对此也作了总结;最后,指出进一步研究的重点和方向。In the environment of grid computing, in order to realize, e one high efficiency and rapid grid how to solve its key technology is an imtportant factor. In this paper the current architecture of grid is analyzed, and some characters of five- layer sandglass and rome merits of open grid scrvices architecture （OGSA） are pointed out, and their similarities and differences are compared under this condition. In addition, the core of grid computing is cooperation of tasks, and in order to resolve this problem, five key technologies referenced in this paper are analyzed in detail. Meanwhile, three kinds of resource management models--layer model, ahstract/owner model and economy/ market model are aiso an indispensable aspect, which are generalized in this paper. Finally the emphasis and direction in the future are pointed out.
