【Abstract】 On the basis of the charge quantization,the quantum fluctuations of the charge,current and energy in the mesoscopic LC circuit are calculated by the character of the minimum translational operator,the effects of the parameters on the quantum fluctuations are investigated.The results show that,taking account of the charge discreteness,the quantum fluctuation of the current and energy in the mesoscopic LC circuit is not zero under Fock state,but related to with the charge quantum and Planck constant respectively,and its quantity is determined by the parameters of the circuit.更多还原
