Abstract : starting from the equation of motion of a non - dissipative mesoscopic circuit with inductance coupling ， the quantum fluctuations of charge and current in the eigenstates of the system and the squeezed vacuum state are investigated . the results show that the quantum fluctuations of the charge and current exist in all of the states . the fluctuations in each component circuit are connected 文摘:本文从无耗散的电感耦合电路的经典运动方程出发，分别研究了这一耦合电路在其任意的本征态下和压缩真空态下电路中电荷、电流的量子涨落，其结果表明，每个回路中的电荷、电流都存在着量子涨落，且两回路中的量子噪音是相互关联的
