摘　　要：借鉴阻尼谐振子的量子力学处理的研究思想,将介观RLC串并联电路量子化.在此基础上,研究了真空态下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参数有关。Mesoscopic series-parallel connected RLC circuit is quantized using the idea of damped harmonic oscillator operation. Quantum fluctuations of the voltage and current of each branch in vacuum state are studied with this basic theory. The result shows that the quantum fluctuations of the voltage and current of each branch are related with parameter of the circuit element, and decay with time.
