摘要 证明了若R是GCD整环,N是有限型的w-模F的w-子模,满足(N:F)=(um),其中u∈R是素元,则存在F的w-子模升链A0= N A1 … Am= F,使得每一Ai是F的( u)-准素子模,且Ai是Ai+1的( u)-素子模.此外,也给出了PVMD上任何有限生成无挠模的二次对偶模的计算办法,即F**=∩{ FP| P∈Ass( K/ R) . In this note, we prove that if R is a GCD-domain and N is a w- submodule of a finite type w-module F with ( N: F) = (u^m), where u is a prime element of R, then there is a chain of w- submodules of F, A0=N belong to A1 belong to …belong to Am=F such that every Ai is a (u) - primary submodule of F and is also a (u) - prime submodule of Ai+1.
