摘　　要：利用阻尼谐振子正则量子化方法,实现了对耗散介观RLC串并联电路的量子化,并在此基础上,研究了基于热场动力学(TFD)理论的热真空态下的电荷和自感磁通链、电压和电流的量子涨落.结果表明,在热真空态下电荷和自感磁通链、电压和电流都存在着各自的量子涨落,且量子涨落及量子涨落积不仅与电路中的器件参数有关,而且还与时间和温度有关.By using canonical quantization method of damped harmonic oscillator,the quantum of dissipative mesoscopic RLC series and parallel circuit was realized in this paper.And on this basis,the quantum fluctuations of charge and inductance flux linkage as the same as voltage and current in circuit under thermal vacuum state which based on thermal field dynamics theory were also studied through this research methods.The results show that charge and inductance flux linkage as the same as voltage and current in circuit under thermal vacuum state respectively exist quantum fluctuations.And the quantum fluctuations and quantum fluctuations plot not only depend on device parameters in the circuit,but also depend on time and temperature.
