摘　　要：用S-Chord环模拟器仿真软件测试分析了S-Chord的效率,以及节点在Chord环中分布与搜索效率之间的规律。仿真测试分两种情况进行,分别为节点在Chord环中平均分布和随机分布。实验结果表明,在节点数目固定的情况下,finger表记录项数目随文件数量增减的变化规律,以及在文件数目固定的情况下,finger表记录项数目随节点数量增减的变化规律,从而显示出S-Chord优势。Based on software of simulation of S-Chord ring, which makes simulations and gives tests on efficiency of S-Chord and laws of distribution of nodes in Chord loop between search efficiency, as well as an analysis. Simulation can be divided into two kinds of situation according to whether the distribution of nodes in Chord loop is even or random. Experiments show the relationship between re- cord number in finger table and file number under a fixed nodes condition, as well as the relationship between records number in finger table between the numbers of nodes. The experiments have testified the superiority of S-Chord.
