设R是任意带单位元的结合环,用素谱[Spect(R),Г^2(R)]的一些拓扑性质去刻画环的性质。对任意环R,用N(R)表示环R的素根,证明了:R/N(R)是强Harmonic环当且仅当[Spect(R),Г^2(R)]是正规空间。且建立了[Spect(R),Г^2(R)]的开闭集与环R的幂等元之间的关系。
Let R be any associative ring with identity. In this paper, some properties of strongly Harmonic ring are obtained by using some topological properties of the spectra [ Specl(R) ,Г^2(R)]. It is proved that if R any ring and N (R) is a prime radical of R, then R/N(R) is a strongly Harmonic ring if and only if [Specl(R), Г^2(R) ] is a normal space. The relationships of clopen sets in [ Specl (R), Г^2(R)] and idempotents in R are investigated.
