In this paper, we study the complete convergence properties and strong laws of large numbers for pairwise NQD random sequences. We present the definition of pairwise NQD random sequences and the Kolmogorov inequality to the case of pairwise NQD random sequences. Based on the Kolmogorov inequality, we obtain complete convergence properties of pairwise NQD random sequences. We construct two non-increasing functions based on the properties of non-increasing function, and obtain some strong laws of large number for pairwise NQD random sequences, which is similar to independent random variable sequences. The theorem obtained in this paper thus inclines to extend the related results presented in previous literatures.
