引入WGCN环的概念,研究WGCN环的一些性质,主要证明了如下结论:1)设R是WGCN环,I是R的理想且I N(R),则R/I是WGCN环;2)设I是R的约化理想,若R/I是WGCN环,则R是WGCN环;3)设e是R的中心幂等元,若eRe,(1-e)R(1-e)是WGCN环,则R是WGCN环;4)设R是交换约化环,则M4(R)是WGCN环.
In this paper, the definition of WGCN rings is given and some properties of WGCN rings are studied. The proved results are as follows. 1) Let R be a WGCN ring, if I is an ideal of R and I N(R), then R/I is a WGCN ring; 2) Let I be a reduced ideal of R, if R/I is WGCN ring, then R is a WGCN ring; 3) Let e be a central idempotent, if eRe and (1-e)R(1-e) are WGCN rings, then R is a WGCN ring; 4) If R is a commutative reduced ring, then M4(R) is a WGCN ring.
