| 摘 要： | 通过矩阵象(MI)技术,给出正交表的混杂度概念,并证明了混杂定理,对于饱和正交表,所有混杂度之和等于交互作用的自由度,最后给出混合水平情形下的交互作用分布例子。

| Abstract: | By using the Matrix Image methods,we present an index for measuring the confounding size of interactions of orthogonal arrays, which is called confounding degree. It is proved that the sum of all confounding degrees is equal to the degree of interaction for any tight orthogonal arrays. As an application of this method, the confounding distributions of or thogonal L20（219） and L18（3661） are presented at last. |
