摘要：

We generalize the condition keeping the special states bound entangled [S.-M. Fei, X. Li-Jost, B.-Z. Sun, Phys. Lett. A 352 (2006) 321] to the general states. Taking the original 4 x 4 states as 2 x 8 states we show that they still can be bound entangled. (c) 2007 Elsevier B.V. All rights reserved.
