摘要：
The system of the Hamiltonian involving a driving part, a single mode part. and a two-mode, squeezed one and a two-mode coupled one is discussed using the Lewis-Riesenfeld invariant theory The time evolution operator is obtained. When the initial state is a coherent state, the quantum fluctuation of the system is calculated, and it is dependent oil the squeezed part and the two-mode coupled part, but not dependent oil the driving one.
