摘要：
The dynamics of a quantum system which is weakly coupled with the quantum chaotic system with a few degrees of freedom is discussed. It is shown that the quantum chaotic system acts like the thermostat and causes the irreversible evolution of the system under interest. The closed equation of the system evolution is obtained. The solutions of this equation are compared with the results of the direct numerical simulation for two particular systems. © 1994 The American Physical Society.
