【Abstract】 In the paper,we study the quantum fluctuations of charge and electric current in mesoscopic LC circuit by using the theory of time-dependent perturbation.In a definite temperature,the system will be in a mixed state,further,we obtain the quantum fluctuations in mesoscopic LC circuit with a power source in a finite temperature.The investigation shows that the quantum fluctuations of mesoscopic LC circuit relate not only to circuit parameters but also to the time and temperature.更多还原
