摘　　要：根据 q元非线性码的广义 Hamm ing重量 ,构造定义了两个关系式 ,通过分析 ,得到 q元非线性码的广义 Hamm ing重量的几个不等关系。这些关系实质上是 2元线性码的广义 Hamming重量在 q元上的推广 。Based on generalized Hamming weights for q-ary nonlinear codes, two relations are defined, and by analysis, some unequal relations of generalized Hamming weights in q-ary nonlinear codes are obtained. Actually, these relations are the popularization of binary linear codes on q-ary element, which help to form an operational mathematics model for the researchers.
