普物实验教学方法的探索——曲线拟合与经验公式的选配

Investigation about Teaching Methods of Common Physics Experiments——Curve Fitting and Empirical Formula Selecting

结合普物实验数据处理,指出用最小二乘法进行曲线拟合,是数据处理常用的手段之一.同时,对低年级学生来说,逐步掌握经验公式的选配,运用经验公式对曲线拟合的处理,是实验内容的重要环节.

This paper points out that it＇s the one of usual methods to make curve fitting using least square method in data processing of common physics experiments. Meanwhile, mastering the selection of Empirical formula progressively and processing curves by empirical formula are important parts to experimental contents for lower grades.
