摘　　要：讨论了一种基于密立根油滴实验的探究性数据处理方法。通过分析平衡电压和下落时间的隐函数关系,并结合实验数据的具体分布推测出电荷的不连续性。在此基础上通过拟合二者的关系曲线计算出基本电荷的电量,从而还原了该实验富有的研究性内涵。This paper aims to propose a new method of the experimental data processing of Millikan ex- periment. By analyzing the implicit function between the equilibrium voltage and fall time,the relation and direct function expression between them have been deduced. Combined with the experimental da- ta,linear fits of equilibrium voltage and {all time has been made out,through image analysis of which the value of basic charge has been acquired. This experiment has confirmed the discontinuities of elec- tric charge,illustrating the importance of equilibrium voltage and fall time limits on the accuracy of the experiment.
