摘　　要：从有源RLC电路的运动方程出发,对电荷、电流经正则变换后量子化;然后采用规范变换的方法,求解含时Schrodinger方程;最后对RLC电路中电荷、电流的量子涨落进行了研究,并对其结果进行了讨沦.Starting from equation of motion of the active RLC circuit, we adopt the technique of the unitary transformation,transform the charge and current into the unitary variable and then have the quantization. By making use of standard transformation,we try to solve the time equation. For the application, quantum fluctuations of charge and the current in the mesoscopic circuit in the harmonic oscillator state are studied, result is analyzed and discussed.
