摘要
当被测量的估计值由实验数据用最小二乘法拟合的直线或曲线上得到时,任意预期的估计值或表征曲线拟合参数的标准不确定度可以用已知的统计程序计算得到。本文用最小二乘法拟合的直线确定三相异步电动机风摩耗测量的标准不确定度。
When the assessed values are gained from the fitting line or curve of least square method using test data, standard uncertainty of random expected and assessed values or fitting parameters of imaged curve can be calculated by using the known statistic program. This paper determines standard uncertainty for measurement of windage and friction loss of three-phase induction motor through fitting line of least square method.
