摘要：在密立根油滴实验中,对大量油滴电荷量数据,首先利用极端数据剔除法找到最佳的电荷量分割区间,然后用峰值法和聚类分析方法分别确定不同电荷量区间实验数据分布的中心.用峰值法和聚类分析方法得到的元电荷量值分别为1.525×10^(-19) C和1.527 1×10^(-19) C,与公认值e=1.60×10^(-19) C的相对偏差分别为4.7%和4.6%,满足了实验要求.
Based on the many data about the charge on the droplets,the best charge division intervals were found using the extreme data elimination method firstly,and the distribution center of the experimental data in different charge intervals were determined using the peak value method and cluster analysis method secondly.The quantities of elementary charge obtained by peak value method and cluster analysis method were 1.525×10^-19 C and 1.527 1×10^-19 C,respectively,and the relative errors were 4.7%and 4.6%,respectively,which could meet the requirements of the experiment.
