摘　　要：开放网格服务体系结构(OGSA)是在Globus网格计算工具包和Web Service技术融合的基础上提出的一套规范和标准。OGSA以服务为中心,将一切都抽象为服务,网格服务是OGSA的基本概念。在介绍了网格服务的思想之后,分析了OGSA的架构体系,讨论了网格服务的组成以及典型标准接口的功能描述,研究了创建网格服务实例的过程,提出了一个网格服务调用模型,并对其处理过程进行了描述。Open grid services architecture is a suit of criterions and standards that are put forward on the basis of merging Globus Toolkit and Web service technology. All in OGSA that gives emphasis to services are abstracted to services, and grid service is the basic conceptions of OGSA. After introducing the basic idea of OGSA, the framework system of OGSA was analyzed. The composition of grid service and the function of the representative standard interface were discussed. The creating course of the grid service instance was researched. A calling model of the grid service was put forward, and the processing course was described,
