环并半环称为纯整环并半环,若其加法幂等元集是一个带半环.若纯整环并半环的加法幂等元集是一个T带半环,称为T纯整环并半环.研究了纯整环并半环以及一些T纯整环并半环的半群结构.
A semiring is an orthoring, if it is the disjoint union of subrings and the set of its additive idempotents is a band semiring. An orthoring is called a T orthoring, if the set of its additive idempotents is a T band semiring. The semigroup structures of orthorings and some T orthorings are studied.
