【摘要】 Um（n，R）表示域F上n元非零向量之集．本文先确定了有限域上n≥5维非零向量的道路图结构，然后利用有限域Fq上Um（n，R）／EnR中具有相同范数的向量的道路图结构与内积构作了具有多个结合的结合方案，并计算出相应的参数．更多还原

【Abstract】 Let Um(n,Fq) denotes the set of nonzero vectors over a finite field F. that contaln q ele-ments, Here we study the path structure of vetors in U.(n,Fq) and use these results to con-struct some association schemes with many association schemes with many association clases and also compute their parameters.更多还原
