摘　　要：本文给出了单形与其切点单形关于外接球半径等不变量之间的两个关系式．Let Ai(i=1,2, ...,n+1) be the vertices of a simplex in En(m≥2) and,A' be the tangent points which the inscribed sphere of is tangent to the side face of , then the simplex with the tangent points as vertices is called the tangent points simplex. Two new inegualities between the invariants of and are given in this paper.
