| 中文摘要: |
| 建立了欧氏空间Ｅｎ中ｎ维单形空间角的准正弦概念，并应用于高维正弦定理的改进、Ｓｔｅｉｎｅｒ定理的高维推广及切点不等式的简化证明；又推出了有关单形的一些新不等式． |
| 英文摘要: |
| The main result of this paper is that the concept of quasi sine of space angle of n dimensional volumes in Eｎ is builded and by it to correction of higher dimensional sine theorem and higher dimensional generalization of steiner theorem and the simply prove of inquality of tangential point. Some new inqualities of simplexes are push out by it. |
