%X 摘要： 设R为有单位元的环,M为右R-模,通过研究多项式环上的表现维数,得到了当R,R[x]为凝聚环时,MR与MR[x]的表现维数之间的关系以及R与R[x]的表现维数之间的关系等结论.<br>Abstract: Let R be a ring with a unit element, and M be a right R-Module. The relationship between FPd(MR) and FPd(MR[x]) as well as between FPD(R) and FPD(R[x]) are obtained by using the presented dimensions of polynomial rings, when R and R[x] are coherent rings
