| 摘 要： | Let R be an(α,δ)-compatible ring.It is proved that R is a 2-primal ring if and only if for every minimal prime ideal P in R[x;α,δ] there exists a minimal prime ideal P in R such that P = P [x;α,δ],and that f(x) ∈ R[x;α,δ] is a unit if and only if its constant term is a unit and other coefficients are nilpotent.

| Abstract: | Let $R$ be an $(alpha,delta)$-compatible ring. It is proved that $R$ is a 2-primal ring if and only if for every minimal prime ideal $mathscr{P}$ in $R[x;alpha,delta]$ there exists a minimal prime ideal $P$ in $R$ such that $mathscr{P}=P[x;alpha,delta]$, and that $f(x)in R[x;alpha,delta]$ is a unit if and only if its constant term is a unit and other coefficients are nilpotent. |
