摘　　要：采用半经典近似方法,研究简谐势阱中二维理想带电玻色气体的磁性质.推导出了该体系的热力学势、相变温度、内能、比热、磁场强度和磁化率随外加磁场的变化关系,进而分析了约束势阱对理想带电玻色气体热力学性质的影响.The magnetic properties of the charged 2D charged Bose gas in a harmonic potential are investigated through the semi-classical approximation. After deriving the relationships on thermodynamic potential, transition temperature, internal energy, heat capacity, magnetization and magnetic susceptibility changed with external mag- netic field, then the influence of harmonically trapped potential on the thermodynamic properties of the ideal charged Bose gas system are analyzed.
