摘　　要：线性拟等重码是一类特殊的等重码 ,文中利用码等价和线性拟等重与一阶 R- M码的关系研究了线性拟等重码的检错性能 ;并证明了一类特殊的二元线性拟等重码是最佳检错码 ,并因此得出延长HammLinear quasi-constant weight code is a class of constant weight code . In this paper, the author used the point of equivalence and the first order R -M codes to prove linear codes property for error detection, and then gave the error capability of extensive Hamming codes by making use of the point of equivalence and some known results.

关 键 词：拟等重码 码的等价 一阶R-M码 延长Hamming码 最佳检错码
