Some properties of the stabilizer of N(2,2,0) algebras are discussed in this paper. Then a congruence decomposition on N(2,2,0) algebras is given by it. Also it is proofed that this congruence is N(2,2,0) algebra congruence. The algebraic structure of the quotient algebras is investigated and the properties of a class of converse image under the natural homomorphism are studied.%讨论了N(2,2,0)代数的稳定化子的性质，并利用稳定化子给出了N(2,2,0)代数的一个同余分解，证明了该同余是N(2,2,0)代数同余，进而研究了商代数的代数结构，并讨论了自然同态下一类逆象的代数结构和性质。
