摘　　要：从正反两个方面论证了两个格的相对凸子格的直积是这两个格直积的相对凸子格,介绍了子格成为相对凸子格的充分必要条件,给出了相对凸子格与幂格之间的关系.The direct product of the relative convex sublattices of two lattices is the relative convex sublattice of the direct product of the two lattices.The paper introduces the sufficient and necessary condition for the sublattice to become a relative convex sublattice.The relation between relative convex sublattice and power lattice is also given.
