| 摘 要： | 实验误差分析是实验教学中的一个重要内容,学生常因不能准确理解测量误差的相关概念和分析方法,而采用了错误的实验数据处理方法。针对这一问题,通过电子自旋共振实验的测量误差分析,简述了直接测量、间接测量及不确定度传递的应用;利用脉冲核磁共振实验的数据分析,说明了曲线拟合与拟合不确定度的使用适应性。两者的物理实验结果表明,实验数据处理不是简单的纯计算问题,而是必须遵从严格误差分析原理的技术方法。

| Abstract: | Error analysis plays an important rose in experimental physics, but it is too often short - changed so that students recite its equations without understanding their rationale. Building on the fundamentals of measurement theory, data from ESR is used to demonstrate the analysis method and its uncertainty in direct or indirect measurements, while result from PNMR is quantitatively presented with least - squares fit. It is much important to help students well understand the principle of data analysis with reasonable processing. |
