Origin软件在数据处理中的应用——以“测定电源电动势和内阻”为例

The Application on Origin Software in Data Processing——Take Measuring the Electromotive Force and Internal Resistance of Power Supply as Example

主要介绍了使用Origin软件进行实验数据处理与线性拟合的具体方法.以"测定电源电动势与内阻"为例,介绍4种不同的实验方法后,对其进行线性变换与线性拟合,得出系统误差并重新自定义拟合函数,对测量结果进行修正,展现了Origin软件便捷、高效、直观的特点.

This paper mainly introduces the specific method of data processing and linear fitting with origin software.Taking "measuring the electromotive force and internal resistance of power supply"as an example, after introducing four different experimental methods,linear transformation and linear fitting were carried out to obtain the system error and redefine the fitting function.The measurement results were corrected,showing the convenience,efficiency and intuition of Origin software.
