查询词典 differentiation theorem

And extended codes of quadratic residue codes over Z〓(Definition 3. 4) also are discussed, which have good dual properties (Theorem 3. 9 and Theorem 3. 10). At last, two kinds of Gray map from Z〓 to Z〓 are defined (Definition 3. 5 and Definition 3. 6), and they are compared with each other, and we find the second Gray map is better than first by an example.

最后，以两种方式定义从Z〓到Z〓的Gray映射并相应的有两种码字的Lee重量定义（定义3.5与定义3.6），并以一实例计算比较了这两种Lee重量定义，指出第二种方式定义的Gray映射更好，因为其相应的Lee重量定义使得相应所得到的最小Lee重量更大。
