置信概率 meaning in Chinese

confidence probability
fiducial probability

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。
