摘要
研究了正交表矩阵象的不变性,利用正交表矩阵象的不变性有时容易发现并证明两个正交表之间的正交性,并且用例子说明了这种方法的应用.
This paper studies the invariability of matrix image of orthogonal arrays. By using the invariability, the orthogonality between two orthogonal arrays can be easily found and proved sometimes. Some examples are presented to illustrate the application of this method.
