摘要：
Some sufficient conditions ensuring that the subdirect sum ofQN-matrices is in the class ofQN-matrices, are given. In particular, new conditions are given to guarantee that thek-subdirect sum of Nekrasov matrices is also a Nekrasov matrix. Examples are reported to illustrate the theoretical results presented.
