摘　　要：采用代数动力学规范变换方法,求出含时变电压源的电容耦合介观电路量子态随时间演化算符的精确解,导出电容耦合介观电路电荷和电流对输入电压信号的零状态响应的完全解,结果表明电容耦合介观电路系统具有线性时不变特性,且电荷与电流的零状态响应与相应宏观电路的结果一致.The exact solution of time-evolution operator was obtained by applying the gauge transform of algebra dynamic. Such an operator describes the quantum state of time dependence of capacitance coupled mesoscopic circuit containing voltage source. The charge and current zero-state response of the import voltage signal in capacitance coupled mesoscopic circuit were introduced. The result shows that the system of capacitance coupled mesoscopic circuit has linear time invariant feature, and the response in mesoscopic circuit is the same as in the macroscopic circuit.
