单形外接球半径和内径的两个不等式(英文)

Two Inequalities Concerning the Circumradius and Inradius of a Simplex

给出了ｎ维欧氏空间Ｅｎ中的两个关于单形外接球半径和内径的几何不等式，同时进一步改进了文［１］和［２］中的ｎ维欧拉不等式。

In two inequalities concerning the circumradius and inradius of an n dimensional simplex in the n dimensional Euclidean space E n were obtained, Thus, the n dimensional Euler inequality and the inequality in , were improved.
