- 摘要:
- 对密立根油滴实验中油滴带电量的随机性进行研究。采用静态测量法得到实验数据后用SPSS软件对数据进行了分析,结合柯尔莫哥洛夫-斯米洛夫检验和夏皮诺-威尔克检验排除实验结果的偶然性,并证实油滴带电量的单峰性、对称性和有界性,验证了油滴电量呈正态分布的规律,进而得到一种人为干扰因素小的随机性验证方法,对实验中的误差分析有启发作用。
- Abstract:
- This paper studies the randomness of the charged quantity of oil drops in the Michigan oil drop experiment. The experimental data were obtained by static measurement and analyzed by SPSS software. The experiment rules out the contingency of the results based on Kolmogorov-Smirnov test and Shapiro-Wilk test, proves oil droplets charged amount of unimodal, symmetry, and boundedness, and verifies the law of oil droplets power normally distributed to obtain a random verification method with little human interference, which is instructive to the error analysis in experiment.
