Recently while reading a paper I encounter a problem, which has confused me for several days. So I hope that some one could help. Thanks for your attention. My problem is: let $R$ be a commutative uniserial ring(i.e., its set of ideals is totally ordered by inclusion), $m$ denotes its unique maximal ideal and Ann(m) denotes the annihilator of $m$. Then $Ann(m/Ann(m))=0$ when $m/Ann(m)$ is treated as the maximal ideal of $R/Ann(m)$.
