摘　　要：引进了与凸体间Banach-Mazur距离相关的位似距离的概念,证明了平面上正七边形与其面积最大内接单形之间的位似距离近似为2.048 9。The concept of homothetic distance which is very close to Banach-Mazur distance between convex bodies is introduced, and the homothetic distance between regular heptagon and simplex is shown as 2. 0489.

关 键 词：Banach-Mazur距离 位似距离 凸体 单形
