等精度测量均方根偏差计算方法的探讨
Study on Calculation Method about RMS Deviation of Equal Precision
【摘要】 探讨了等精度测量均方根偏差的计算方法 ,即σ已知时和σ未知时单次测得值X和算术平均值Xm的均方根偏差计算方法 ,探讨了它们之间的相互关系、在实践中的处理方法以及提高均方根偏差可靠性等问题。
【Abstract】 This article discusses study on calculation method about RMS deviation of equal precision measurement,i.e.,about RMS deviation of single-measured value X and arithmetic average value Xm when σ is known and unknown. The mutual relation between them,the practical hardling method and the way to improve reliability of RMS deviations are further discussed.
