摘要：
We consider the quasi-twisted codes as contractions of quasi-cyclic codes and construct a family of q-ary quasi-cyclic codes whose codewords have r-divisible weights, where r | q - 1. We show that any quasi-cyclic code of co-index divisible by r is a direct sum of r-divisible quasi-cyclic codes.
