摘要 利用环F2+uF2上线性码C的生成矩阵给出了码C的对偶码C⊥及其Gray象Φ(C)的生成矩阵,证明了环F2+uF2上线性码及其对偶码的Gray象仍是对偶码,并由此给出了一个环F2+uF2上线性码为自对偶码的充要条件。 Based on the generator matrix of linear codes C over F2 + uF2, the generator matrixes of the dual codes C^┴ and the Gray images Ф(C) of the linear codesC are given, and the proposition that linear codes Ф(C^┴) are the dual codes of Ф(C) are showed. By using this proposition, the necessary and sufficient condition of a linear code over F2 + uF2 which is self-dual is obtained.
