大学物理实验中不确定度测量问题探讨

Discussing Some Problems about Indeterminate Degree in Normal Physics Experiment

为了适应新世纪的高科技人才的需要,物理实验课中正在逐步推行用不确定度评定测量结果,但是从学生的实验报告中发现了许多问题,大多数问题集中表现在实验结果的表示上,文中有针对性地介绍了不确定度的概念、物理实验的结果及其不确定度的有效位数,为学生在物理实验中的数据处理提供参考.

In order to adapt to high-tech talents in the new century, indeterminate degree are being gradually introduced to assess the measurement results in the Course of physics experiments. However, many issues are found in the student＇ s reports, which focus on the expression of the experiments results. This article focuses on the concept of indeterminate degree, the results of physics experiments and the significant digit of indeterminate degree, which provide data reference for students in physics experiments.
