摘　　要：利用含时波戈留波夫变换与时间演化方程相结合得到的求解SU(1,1) h(4)量子系统的时间演化算符和演化态的普遍公式,我们导出了带腔损耗的参数振子在弱耦合近似下的演化算符,态函数和不确定乘积,并讨论了系统的压缩特性。Using the formulized approach to the SU(1,1)h(4) time-dependent system, which is derived from the combination of the formulation of the time-dependent Bogoliubov transformation and the evolution equation of the system, we obtain the time evolution operator、 state function and product of the uncertainties of the parametric oscillator with cavity losses under the weak coupling approximation. We also discuss the squeezing property of the system.
