扩展不确定度 meaning in Chinese
expanded uncertainty
Examples
- The uncertainty effects in measurement was analyzed and the uncertainty in measurement can reach u = 0 . 4 %
文中详细分析了影响焦距测量不确定度的因素，焦距的测量扩展不确定度可达到u = 0 . 4 % 。 - Measurement uncertainties of hch and ddt residues in meat were evaluated , key procedures of which were listed , and important components were chosen from those factors affecting measurement results for composed and expanded uncertainty calculations
并通过对各个不确定度分量的分析计算，然后计算出合成不确定度和扩展不确定度。 - In the linear dose range , the extensive uncertainty of alanine / esr dosimetry system is 4 % for 60co y - ray irradiation and 6 % for electron beam irradiation ( in 95 % confidence level )
在线性剂量范围内，该剂量体系测量60co射线和电子束吸收剂量的扩展不确定度分别为4 . 2和6 . 2 ( 95置信水平) ，适合作为电子束传递剂量标准。 - Based on the quantitative analysis of each source , the extended uncertainty of measurement results was obtained from standard uncertainty ( synthesis of uncertainties from each source ) multiplied by an extended factor of 2 ( under confidence probability of 95 % )
在对各个不确定度分量进行量化的基础上，通过合成得到测量结果的标准不确定度，再乘以95 %置信概率下的扩展因子2 ，得到测量结果的扩展不确定度。 - Abstract : the error source of raster indicator verification instrument is analized . the synthetic standard uncertainty and expansion uncertainty of the standard unit is determined . the reliable basis for the verification of indicating type measuring tool is provided
