| 摘 要： | 从数理统计、误差理论和计量学的角度,对在线水分仪探测精度的两种不同评定方法进行了解析。指出:从误差理论和计量学的角度出发,用于描述随机误差分散程度的标准偏差不宜用于评定在线水分仪的探测精度,采用绝对误差、相对误差和引用误差进行评定是较为合适的方法。

| Abstract: | Two different ways for the assessment of online moisture meter accuracy were analyzed from the views of mathematical statistics,error theory and metrology.It was pointed out that from the angles of(error) theory and metrology,the standard deviation was good for describing the dispersion of random errors;for evaluating the detection accuracy of online moisture meter,the absolute error, relative error and fiducial error were more suitable. |

| Keywords: | Measurement error Standard deviation Expectation value Residual error Error Random error Systematic error |
