英文摘要：

The open electron resonator is a mescoscopic device that has attracted considerable attention due to its conductance periodcal fluction with gate voltage.Based on an equivalent Hamilton of the device,the open electron resonator is quantizated using Feynman＇s path integral method.The propagator of the system is obtained by method of undetermined coefficients.The wave function is calculated,the quantum fluctuation of charge and currents,uncertainty relation are discussed.The results show that the quantum fluctuation of open electron resonator is same as a pure LC circuit＇s.
