摘要
以伏安法测电阻为例,分别用作图法、逐差法、最小二乘法对实验数据进行了处理,并比较了这三种常用的处理实验数据方法的不确定度的评定.
Take Volt-Ampere law used to measure a resistance in physical experiment as an example, it is calculated with graphical solution, gradual deduction method and least square method respectively. In addition,it is discussed on the assessment of the uncertainty on these methods.
