论文摘要
引入了不交联矩阵的概念，作为正交设计的概括。递归结构以及计算机搜索导致一些无限类别的不相交矩阵，而矩阵又显示出具有3或4个类别的换向关联方案。
The notion of disjoint weighing matrices is introduced as a generalization of orthogonal designs. A recursive construction along with a computer search lead to some infinite classes of disjoint weighing matrices, which in turn are shown to form commutative association schemes with 3 or 4 classes.
