摘要： 提出划分矩阵和布尔列向量取小乘法的概念；证明了下矩阵和上矩阵的行并向量分别是下近似和上近似；研究了上下近似的性质；给出了计算上下近似的算法。
Abstract: The concept of min-product between partition matrix and Boolean column vector is presented.The results that row-union vector of lower matrix is lower approximation and row-union vector of upper matrix is upper approximation are proved.Some properties of upper and lower approximations are studied.Finally，an algorithm to computer upper and lower approximations is established.
