摘要
针对普朗克常数的传统实验数据处理方法误差大及其不确定性等弊端,利用改进的拐点法,使用origin 8.0软件的微分功能于光电效应实验中测定普朗克常量.结果显示,实验中5个测量点的相关系数为0.994 59,误差大大减小.该方法使数据处理更加准确、高效,也使教学过程具体、形象,提高了教学效果和质量.
Traditional experimental way of handling data has big errors and is unstable.To address these problems,an improved inflection-point method is adopted,and the differential function of origin 8.0 software is used in measuring Planck constant in photoelectric effect experiments.The results show that the correlation coefficient of the five measuring points is 0.994 59,and that the errors are dramatically reduced.Moreover,the data processed by using this method are more accurate and effective,making teaching process concrete and vivid.The effects and quality of teaching practices using this approach are,therefore,improved.
