摘要
本文通过一系列的么正变换，得到了质量与频率随时间变化的谐振子系统的波函数．进一步利用此波函数构造了此系统的压缩态，并精确求解了一种特殊的质量与频率随时间变化的谐振于系统．
in this paper? the wave function of a harmonic oscillator with timc-dependent mass and fi'equellcy is obtained by a sequence of unitary transformations.With the help of the wave function, the squeezed state of the system is also con-structed. A specific model of mass and frequenlcy variation for the time--dependentharmonic oscillator is studied as an illustrative example.
