基于最小方差的声速测量实验数据不确定度分析尺度

物理实验的不确定度分析是大学物理实验中的重点、难点内容。通过对声速测量实验中波长的测量不确定度进行分析,得出测量数据无偏估计和有偏估计时,测量次数对测量结果的影响。

Experiment Data Uncertainty Analysis Scale of Sound Velocity Measurement Based on the Minimum Variance

uncertainty analysis of physical experiment is the key point and difficulty content of the college physics experiment, this paper analyze the wavelength of the uncertainty of measurement by the experiment of velocity measurement, from this we know how the measurement times influence the result of the measurement when the measurement data is unbiased estimation and biased estimate.
