摘要
取有限域 F_q上2×2+2维伪辛空间中（2,0,0,0）型子空间作为处理,构作了具有4个结合类的结合方案和PBIB设计,并且计算了它们的参数。
Taking as treatments the subspaces of type(2,0,0,0) in the 6-dimen-sional pseudo symplectic space over finite fields, we first give the association scheme with 4 associate classes,then construct two PBIB designs and calculate their parameters.
