讨论了108次混合正交表,借助于计算机程序,将计算机搜索的方法应用于投影矩阵正交分解构造正交表的方法中,构造了一些新的混合正交表.
In this paper,108 mixed orthogonal arrays are studied.By the way of computer search on orthogonal decomposition of projection matrics,some new mixed orthogonal arrays are obtained.These mixed orthogonal arrays are seed arrays in constructing other orthogonal arrays.
