QUANTUM DYNAMICAL MODEL FOR WAVE- FUNCTION COLLAPSE IN MACROSCOPIC LIMITS

HUANG Wan-xia,WANG Qin-mou(Institute of Physics Department and Electronic Information, An Hui Normal University,Wuhu 241000, China)  
In this paper, we deduce easily the coherent term of the quantum dynamical model by improving the character of displace operators and the character of coherent states. At the same time, we deduce the off-diagonal term of the reduced density matrix is the product of two coherent states. At last, we carry out decoherence of two special case in macroscopic limits.
