摘要：
In this paper, we give an sufficient and necessary condition that a polynomial is irreducible over F-q. For different odd primes k, l and p, we obtain generator polynomials of constacyclic codes of length kl(a)p(b) over finite field F-q, where charF(q) = p and (ord(kq),l) = 1. And we answer the question in [3] under the condition. (C) 2016 Elsevier Inc. All rights reserved.
