摘要
通过对Franck-Hertz实验中的电子能量分布及其动态变化的分析,对Franck-Hertz曲线的规律性波动现象作出了直观的解释.对充汞Franck-Hertz管,考虑了电子的额外加速程、汞原子的多能级共同激发以及电子与汞原子非弹性碰撞后电子具有剩余能量等因素,对Franck-Hertz实验的物理过程有了更全面的了解,并对Franck-Hertz曲线峰间距随加速电压增大而持续变大的现象作出了解释.
By analyzing electron energy distribution and its dynamic alteration in Franck-Hertz experiment,the regular fluctuant phenomenon of Franck-Hertz curve was explained intuitively.For Franck-Hertz tube filled with Hg,considering the effects of an additional acceleration path of electrons,the joint excitation states in multiple levels of Hg atoms,and the surplus electron energies on the process of electron-atom collisions,the physics process in Franck-Hertz experiment was understood better.At the same time,the increase of spacing between minima or maxima in Franck-Hertz curves with accelerating voltage was explained.
