摘　　要：介绍了n维有限射影几何上子空间的性质,利用这些性质研究了非适应性群测模型(d,r)-析取矩阵,然后计算了(d,r)-析取矩阵的相关参数,给出了它的行界.The first, it introduced some containing properties of subspaces in the n-dimensional projective space over Fq. By these properties , a (d,r)-disjunct matrix is studied, then the related parameters were counted , and bound of its related parameters were obtained.
