曲面的三个基本形式的系数矩阵之间关系的证明

摘要

给出R3中曲面的3个基本形式的系数矩阵之间关系的一个直接证明,并由此得到曲面的3个基本形式之间的关系表示及其一些应用.%In this paper, we give a direct proof of the relation among the coefficient matrixes with three fundamental forms of a surface in R3. From this results, we obtain a relation among three fundamental forms of a surface and its some application.
