摘要
结合实测数据,采用Origin8.0软件对实验数据进行线性拟合及绘图,通过图像斜率和截距法,计算电源的电动势和内阻.实验计算结果表明,利用Origin8.0软件处理"测定电源的电动势和内阻"实验数据非常准确和高效,避免了人为因素所造成的误差.上述方法可以很好地应用于物理实验中线性关系变量的实验数据分析与处理.
s:According to our actual experimental data ,the method of linear fitting is used to calculate Electromotive Force and Resistance of Power Supply by origin software .The experimental results show that the value calculated by the slope and intercept are very accurate and efficient .The application of origin software not only can avoid personal error ,but also can make the analysis of the experimental date scientifically and quickly . The method mentioned above can be successfully applied in the data processing of other basic physics experiments with linear relation variables .
