摘要
以测定电源的电动势和内阻实验数据处理为例，运用Origin作图软件建立数学模型和相关系数检验，采用线性回归方法和最小二乘法原理来处理，得到最佳的方程和准确的结果．上述方法也可以很好地应用于基础物理实验中其他线性关系变量实验数据的分析与处理过程．
Taking the experimental data processing in measuring the electromotive force and resistance of power supply as an example, the mathematical models and the correlation coefficient were established by using the origin mapmaker. As well as, the least squares algorithm and the method Of linear regression were also adopted. The results show that the optimal equation and the accurate results could be obtained. The method mentioned above can be successfully applied in the data processing of other basic physics experiments with linear relation variables.
