摘　　要：在结合P 2P技术和G rid技术的P 2P-G rid系统中局部网格系统规模适中的情况下,根据资源属性对资源进行分类组织,把属性相同或相似的资源聚集地组织在一起,可以实现这些资源的一次性查找,其时间复杂度可以缩短到O(5)常量阶,并通过重定位机制,可减少对资源的重复搜索操作.P2P-Grid model is introduced and every super Peer is a local grid system in this model. All resources in local grid systems are organized into high-performance-computer manager,PC manager or LAN manager according to the capacity of computing. Based on the layered resource-directory-tree,the time complexity of resource discovery is decreased to O（5）, and the matching degree of task and resource is increased. At the same time ,the tasks may move between Super Peers, and bottleneck is avoided in P2P-Grid system.
