| 摘 要： | 本文讨论了二元等重码的对偶距离分布和对偶重量分布，首先给出了二元码的对偶重量分布和对偶距离分布的定义，性质和关系，然后对等重码，导出了其对偶重量分布的一个递推关系式，以此得到了对偶距离分布的一个递推不等式，最后，讨论了上述分布的一些应用。

| Abstract: | In this paper, dual distance distribution and dual weight distribution of binary con-stant weight code are discussed. First, their definitions, properties and relations are giv-en. Then, for constant weight code, a recursive equation of dual weight distribution,which implies a recursive inequality of dual distance distribution, is obtained. Finally,some applications of the above distributions are given. |
