摘要
从半群理论的观点出发，证明了群的同余格与它的正规子群格是完备格同构的。
In this paper,
from the point of view of semigroup theory, author proves that the congruence lattice of a group is
completely lattice isomorphic with the lattice of its normal subgroups. This rusult strengthens well
known traditionary result about these two lattices.
