| 摘 要： | 用直线函数拟合了环境温度与空气粘滞系数的关系，并利用VisualBasic编写了密立根油滴实验的数据处理程序，提高了计算油滴带电量的准确性。利用VisualBasic程序的可视化界面形式体现，简化了数据处理过程。利用Origin软件对实验数据进行处理，直观显示了平衡电压、下落时间与油滴所带电荷数的关系。

| Abstract: | The data processing program of ＂Millikan oil drop experiment＂ was simulated using Visual Basic. The relation between environmental temperature and viscosity coefficient was linearly fitted, which helps obtaining more accurate electric quantity for oil drop. A GUI program was built with Visual Basic. Furthermore, the data of the experiment was analyzed by Origin; the relations between equilibrium voltage, dropping time and charge number were obtained. |
