In this paper, we are mainly concerned with semicontinuity of complete lattices and their distributive reflections, introduced by Rav in 1989. We prove that for a complete latticeL, the distributive reflectionLdis isomorphic to the lattice of all radicals determined by principal ideals ofLin the set-inclusion order, obtaining a method to depict the distributive reflection of a given lattice. It is also proved that if a complete latticeLis semicontinuous and every semiprime elementx∈Lis the largest ind(x), thenLdis continuous whenever the distributive reflectordis Scott continuous. We construct counterexamples to confirm a conjecture and solve two open problems posed by Zhao in 1997.
