摘　　要：对介观耗散LC并联电路作阻尼谐振子处理,将其量子化。在此基础上,研究了Fock态及压缩真空态下,介观耗散LC并联电路中各支路电流和电压的量子涨落。结果表明,各支路电流电压的量子涨落均与电路器件的固有参数及所选量子态有关。Mesoscopic dissipative parallel LC circuit is quantized by the method of damped harmonic oscillator quantization. We studied quantum fluctuations of the voltage and current of each branch in Fock state and squeezed vacuum state. The result shows that the quantum fluctuations of the voltage and current of each branch are related with parameter of the circuit element, quantum states, and decay according to exponent along with time.
