摘要
证明了En中n维单形的一个(n1)重向量恒等式,并应用它得到了n维单形的中面面积公式,进而给出了n维单形的中面面积与二面角平分面面积之间的一个不等式.
An identity ralate to (n1)vector in nsimplex in En is proved, and by appling the identity, the area formula concerning the central plane of the nsimplex is obtained. And then, an inequality associated with the central planes area and the bisction planes area of dihedral angle of nsimplex is proved.
