【摘要】 在弗兰克-赫兹实验中,温度等环境因素的变化会导致灯丝电压、控制电压、拒斥电压设置不当造成实验数据不理想;同时随着实验仪器高强度的使用,弗兰克-赫兹管逐步老化也会引起工作状态不稳定.针对这2种情况,采集了不同工作参量下的弗兰克-赫兹曲线作为工作参量调整的依据,同时增设数字示波器,可直观观测弗兰克-赫兹曲线,灵活调整工作参量.更多还原

【Abstract】 In Frank-Hertz experiment,environmental factors such as temperature could lead to improper configuration of filament voltage,control voltage,and exclude voltage,and at last result in bad experiment data.Simultaneously,the instrument was always under extensive use which could accelerate the aging process of the Frank-Hertz tube.To solve these problems,Frank-Hertz curves were obtained under different working conditions to provide accurate reference for adjusting the working parameters.At the same time,digital oscilloscope was used to intuitively observe the Frank-Hertz curve,and adjust the parameters flexibly.更多还原
