研究了环Fp +vFp上线性码的Lee重量计数器与对称重量计数器。利用(Fp +vFp)n 到(Fp)2n的Gray映射φ,证明了环Fp +vFp 上自对偶码C的Gray像φ(C)也为Fp 上自对偶码,进而给出了两个MacWilliams恒等式及其应用。

The Lee weight enumerators and the complete weight enumerators for the linear codes over ring Fp +vFp were studied.By using the Gray map φfrom ( Fp +vFp ) n to F2np , it is proved that the Gray images of the self-dual codes over Fp+vFp are the self-dual codes over Fp , and then correctness and application of the two MAcWilliams iden-tities are given.
