摘　　要：在n维欧氏空间中,建立了n维共球有限点集的k号心概念,并据此导出了一串有关的平行线、共线点、共点线及共球点定理.The concept of ＂No, k center＂ of a cospherical finite point set in the n-dimensional Euclidean space is established, according to which a set of related theorems about parallel lines, coUinear points and cospherical points are derived.

关 键 词：N维欧氏空间 n-1维超球面 共球有限点集 K号心 k号超球面
