关于准正交变换的几个条件

Some conditions for Almost Orthogonal Transformations

给出了准正交矩阵的概念 ,在文 [1]的基础上研究了Euclidean空间中的变换是准正交变换的几个条件 ,得到了准正交变换的一些新性质 ,推广了有关正交变换的相应结果。

In this paper, we defined Almost Orthogonal Matrix, Gave some conditions for a transformation on an Euclidean space being an Almost Orthogonal Transformations, and obtained some new properties of Almost Orthogonal Transformations, which generalize the corresponding results on Orthogonal transformations.
