摘　　要：汽轮机热力性能试验的不确定度主要由试验方法的不确定度和测量不确定度组成。根据试验选择合适的试验标准,试验标准规定的试验方法所具有的不确定度即为本次试验的基本不确定度。针对试验中对于试验标准要求的各种偏差产生的不确定度影响进行分析计算,用方根和的方法将所有的不确定度影响进行合成,求出试验的总不确定度。The uncertainties in thermaldynamic performance test of steam turbines are mainly the uncertainties of test methods and measurement. Select appropriate test standards according to the experiment, and the uncertainty of test methods specified in the test standards is fundamental uncertainty of the experiment. Analyse and calculate the impacts of uncertainties caused by deviations required in the standards in experiment, then combine all the impacts with the method of square root of sum to get the total uncertainty of the experiment.
