从偏序的角度出发,给出了乘法半群为逆半群、加法半群为半格的半环成为逆半环的等价刻画和逆半环成为单演双半格的充分必要条件.
We study the inverse semiring and give the equivalent characterization of a semiring S whose multi- plicative reduct is an inverse semigroup and additive reduct is a semilattice are inverse semiring by partial order. We obtain the sufficient and necessary condition that an inverse semiring is a monibisemilattice.
