中文摘要：
介绍了社会关系集中到分层的网格，中间层采用基于小世界模型构建的社会关系网络——关系网格．这种架构在集中管理的高效率和完全分布的可扩展性之间达成平衡．在构建关系网格的过程中，提出了兴趣度限制关系网格，以节省开销，提高资源发现效率．仿真实验结果表明，HRRD（Hierarchy and relation grod resource dicovery）算法大大精简了搜索空间，提高了网格资源发现效率．
英文摘要：
This paper introduces a grid based on hierarchy and social relation, the middle layer is relation grid which constructed of small world network. Such frame achieves a balance between efficiency of centralized management and scalablity of distribute structure. In the process of building relation grid, put forward the restriction of interest degree to save rests and improve efficiency of resource discovery. The simulation results show that HRRD （Hierarchy and relation grid resource dicovery） algorithm greatly streamlines the search space and improves the efficiency of grid resource discovery.
