摘要
在文献 [1]的基础上 ,首次找出了 (非线性 )极大等重等距码 (n,2 k,m)的一类特殊等价分类的普遍性结构 。
Based on the literature ,the author initially obtains the general structure of a kind of peculiar equivalent class and supplies the proof of the weight distribution property about the unextendable binary non linear codes with constant weight and distance for( n,2k,m ).
