Abstract
The structure of multiplicative normal and distributive semiring has been studied.We prove that this kind of semiring is a pseudo-strong semilattice of rectangular semiring varieties,and characterize the direct product of this kind of semiring and semiring,which has a unit element and a multiplicative semigroup band,as a pseudo-strong semilattice of R-semiring.
