摘要：
We find that the coherent thermal state \eta> (H.-y. Fan et al., Phys. Lett. A 246 (1998) 242) can provide a new approach for studying quasi-probability distribution of density operators and their time evolution. This approach is convenient and concise because the \eta> state possesses well-behaved proper-ties and is based on the thermal field dynamics. (C) 2002 Elsevier Science B.V All rights reserved.
