【摘要】 在夫兰克-赫兹实验中,I-UG2K曲线随反向电压增大向右下平移,当反向电压较大时,还会出现"负电流".本研究从电子在电场中的运动过程出发,分析电子与氩原子的相互作用,探讨"负电流"产生的原因.更多还原

【Abstract】 The curve I-UG2K is moving down as soon as the backward voltage increment in Franck-Hertz experiment.When the backward voltage is enlarged enough,negative current is appearance in the I-UG2K curve.We track the action of the electron in the field,discuss the interaction between the electron and Ar and search the whys the negative current in this paper.更多还原
