英文摘要：

In this paper, we study properties of convex sublattice in lattice, and establish relation between power lattice consists of nonempty convex sublattices and power lattice. It is proved that power lattice is isomorphic to sublattice that power lattice consists of nonempty convex sublattices in distributive lattices.
