| 摘 要： | 本文首先找到了质量与频率随时问变化的受迫谐振子的Lewis-Riesenfeld不变量,然后求出了此系统的精确解。进一步,我们利用此精确解建立了质量与频率随时间变化的受迫谐振子的相干态,并对此相干态的一些性质作了讨论。

| Abstract: | In this paper, the Lewis-Riesenfeld invariant, for the driven harmonic oscillator with time-dependent mass and frequency is found and the exact solution for this, oscillator obtained. The coherent state for this system is constructed by making use of the exact solution and some properties for this cohere nt state are disscussed. |
