The least skew-ring congruence on E-inversive E-semiring is described,and the structure of a class of E-inversive E-semiring is obtained,which is the subdirect product of distributive lattice and skew-ring.

In section six, we investigate the Gorcnstcin injective dimensions in direct products of rings, the main result is the following:Let R =ΠR_i be a direct product of rings and let M = M_1 (?)M_2(?)……(?)M_n be adecomposition of an R-module into R_i modules.
