摘要

通过建立密立根油滴实验中油滴下落的动力学数学模型，解释了油滴从开始下落便可视作为匀速的“合理性”。同时从微观分子碰撞角度解释了空气黏滞系数修正因子“ｂ”的物理意义。最后使用直接代入公式法、修正Ｒ公式法和迭代运算法三种实验数据处理方法计算元电荷值，并得出迭代运算的方法得出的数据更稳定且误差小的结论。

Abstract:

The dynamic mathematical model of oil droplet falling in Millikan oil droplet experiment isestablished,and it is explained that the oil droplet can be regarded as the " rationality’of uniform velocity atthe beginning of falling.At the same time ,the physical meaning of the air viscosity coefficient correction factorb’is explained from the perspective of microscopic molecular collision.Finally, three experimental dataprocessing methods, direct substitution formula method, modified R formula method and iterative operationmethod,are used to calculate the element charge value, and the conclusion that the data obtained by theterative operation method is more stable and the error is small is obtained.

Key words: Millikan's oil drop experiment static balance method correction factor iterative operation
