Result: Uncertainty in each ponderance were analyzed and put forward combined standard uncertainty resides of the method.
结果：量化各不确定度分量，提出了该法的合成不确定度评估结果；
But if we are not sure about whether the effective freedom degree is more than 10, it is doubtful that selecting expanded uncertainty as twice as combined standard uncertainty.
但如果不知道有效自由度是否大于10，而直接取扩展不确定度等于两倍的合成标准不确定度是存在疑虑的。
When these input quantities were correlative, the combined standard uncertainty could not calculated if the correlation coefficient was unknown.
当输入量之间的相关性存在时，必须知道了相关系数，才能计算合成标准不确定度。
This method is used to evaluate the demonstration case in ASME PTC6-1996, the combined standard uncertainty of turbine heat rate obtained is close to results giving in the standard.
对于像汽轮机热耗率等这样复杂的间接测量问题，采用传统不确定度传递律法进行合成不确定度的评定是很困难的。
