| 摘 要： | 平面上n个不同的点间的最大距离和最小距离的比记作r_n，r_n的下确界设为R_n。在本文中我们证明了文献[2]中提出的猜想：这里c1＝1.050075…，并对某些特殊的n值，给出了更为精确的上界估计.

| Abstract: | A set of n points in the plane determines a total C2n distances (Some of them may be the same). Let rn be the ratio of the maximum distance to the minimum distance,and Rn be greatest lower bound for rn.In this paper the new upper bound for Rn is obtained,that is to say:Rn
