| 摘 要： | 提出了一种在数据网格环境下的基于虚拟组织区域性分割定位节点的副本定位机制,利用将副本定位信息按虚拟组织区域特性或访问的频繁程度（权重）分布存储到各定位节点上,同时利用虚拟组织域内副本定位机制来完成本地副本的查询,节点请求的副本信息不在它所在虚拟组织时,就采用域间副本定位方法来完成副本查询。

| Abstract: | This paper proposes a decentralized replica location mechanism based on virtual organization and Temtory. In this mechanism, replica location information is partitioned to location sites by virtual organization and territory or the frequent degree of visitine the meanwhile intra-domain query is completed by local virtual organization,and the inter-domain query is completed by territory virtual organization where the request information is not in the local virtual organization. |
