摘要
采用笛卡儿直角坐标法,定义了高维共球有限点集的"欧拉超球面"(它是三角形欧拉圆的高维推广)、"2号心"等概念,并揭示了它们的一系列基本性质.
The ＇Euler hypersphere＇ （It＇s the generalization of Euler circle of triangle in the higher dimensional space） and ＇No 2 centerr of the higher dimensional consphere finite point sets is defined by Cartesian coordinates method, and its properties is studied.
