| 摘 要： | 根据Lewis-Risenfeld的量子不变量理论,研究了时谐LC电路的量子效应。结果显示:由于电路参数随时间变化,在含时相干态下LC电路中电荷和电流量子涨落的不确定度乘积不可能达到最小值h-2/4。

| Abstract: | Following the method of invariants of Lewis and Riesenfeld theory,a quantum effect of the mesoscopic LC circuit for the time dependent has been studied in the coherent state.The results show,because of circuit parameters with the time dependent,the uncertainty in charge and current does not attain its minimum value h- 2/4 in the coherent state. |
