【摘要】 设C为二元非线性2－重量码（n，2，ω1,ω2），本文讨论了C的不可检错误概率．首先给出了C成为最佳检错码的一个必要条件；接着我们证明了当n＞2ω2时，C一定不是最佳检错码；然后，对于ω1＋ω2＝n的情形，我们找出了其中所有的最佳检错码．更多还原

【Abstract】 The error-detected abilitiy of binary nonlinear 2-weights codes is studied inthis paper. First, a necessary condition of binary nonlinear 2-weights codes being properis proposed. Then, we show that there exiests no binary nonlinear proper 2-weights codeswhen n>2ω2. Finally, for binary nonlinear self-complementary 2-weights codes, we find allproper one.更多还原
