摘　　要：对XD-FHZ智能实验仪在测氩原子第一激发电位时,在不同的灯丝电压、栅极电压和反向电压下进行实验,并对各种误差出现的可能性作具体分析,指出减小误差的方法.综合各种因素,给出最佳参数组合,并在此组合下给出了测量数据及处理结果,灯丝电压Uf=3.0V,栅极电压U1=1.8V,反向电压U3=7.0V.在该参数下测得氩原子的第一激发电位U0=11.6V.The paper puts forwards the solutions to reduce the errors in experiment of determining the first excitation potential of the Argon atom with intelligent instrument, named XD-FHZ, at different filament voltage, grid voltage and reverse voltage, and the possibility of errors are analyzed. Taking the comprehensive factors into considerations and the experimental curve results, the optimum parameter are the filament voltage Uf is 3.0 V, the grid voltage U1 is 1.8 V and the reverse voltage U3 is 7.0 V, the first excitation potential of Argon is l1.6 V.
