在基于分布式哈希表构造的对等网络中，路由表的结构影响关键字的查询效率。
In the peer-to-peer network based on Distributed Hash table (DHT), the structure of routing table impacts the efficiency of searching keywords.
当前对等网络研究的重点是基于分布式哈希表的资源定位问题，以及基于节点间信任机制的交互安全问题。
Currently, the research of p2p is focused on resources location based on distributed hash table and transaction security based on trust mechanism between peers.
最后得出基于分布式哈希表的结构化对等网络依据资源标识符进行查找，可扩展性和查找效率都很高。
At last, we give advantage and disadvantage respectively. structural P2P which based on DHTs search resource by resource id, expansibility and search efficiency is the best.
