中文摘要：

文章通过分析最大度优先搜索策略在搜索步数大和查询信息量大的问题,并与次大度优先搜索策略进行比较,发现搜索效率的提高并不完全取决于节点的最大度.提出并设计了二分度的P2P优先搜索策略,使最大度优先搜索策略存在的问题得到了显著改善.

英文摘要：

This paper has analyzed and studied the problems of the larger number of search steps and the large amount of query information existed in maximum degree search strategy,and compared with the second max degree search strategy.It also found that search efficiency was not entirely dependent on the maximum degree of a node.Therefore,this paper proposed and designed a P2P search strategy based on bisection degree,and improved these issues in maximum degree search strategy significantly.
