对介观复杂耦合电路量子化和哈密顿量对角化，研究了压缩真空态、真空态下回路中电荷和电流的量子涨落．结果表明，介观复杂耦合电路中存在电荷和电流量子涨落，这种量子涨落不仅与电路器件的参数、压缩因子、压缩角有关，而且还和彼此的互感耦合、耦合电容、耦合电感有关．

Mesoscopic complicated coupling circuit is quantized, and Hamiltonian is diagonalized by unitary transformation. The quantum fluctuations of the charge and current of each loop in the squeezed vacuum state and vacuum state are researched. The results show that quantum fluctuations are related to not only circuit device parameter, squeezed coefficients and squeezed angle, but also coupled magnitude of mutual inductance, capacitance and inductance.
