摘要
讨论了分配格Ｌ上的秩－１矩阵分解为向量叉积的特点，然后得到对Ｌ上的任一矩阵Ａ，只要，则在Ａ中插入或去掉元素都是λ的行（或列）所得矩阵与Ａ有相同的Ｓｃｈｅｉｎ秩．
This paper discusses the specific property of a rank-1 matrix over distributive lattice Lwhen it is decomposed into cross-vector. It is also proven that,if a matrix A over L has a row(or column) whose entries are all λ (where ),then deleting the row (or column) fromA does not change the Schein rank of A.
