Completely regular congruence on an eventually regular semigroup is uniquely determined by its kernel normal system.
拟正则半群上的两个完全正则同余相等当且仅当它们的核正规系相同。

In this paper, based on the relation between normal subgroup and congruence, another depiction of normal series power semigroup is given from the angles of congruence by the method of analogy.
So We have prove that each P-congruence on P-regular semigroups is uniquely determined by its partial kernel normal systems containing idempotent elements.
