| 中文摘要: |
| 研究了置换QB-环上的有限生成投射模, 证明了QB-环可以通过有限投射生成子的外替换和内替换来刻画.
同时, 还研究了QB-环上投射模的消去性. |
| 英文摘要: |
| The author investigates the finitely generated projective modules over exchange QB-rings.
It is shown that exchange QB-rings can be characterized in terms of outer substitution and inner substitution of progenerators.
The cancellation of projective modules over QB-rings is also studied. |
