本文利用特征为２有限域上Ｚｖ＋１维伪辛几何中一类１维非迷向子空间构作了三个结合类的ＰＢＩＢ设计，并计算了参数。
Fq is assumed to be a finite field of characteristic 2, and K= , also, the set of 1-dimensional non-isotropic subspaces over Fq is taken as the set of treatments to construct an association scheme. Three associative classes of PBIB designs are made and the relevant parameters are computed.
