摘　　要：评定了氧弹热量计、示差扫描热量计、水流型气体热量计的测量不确定度,并分析了各不确定度分量的来源。结果表明,影响热量计测量不确定度的主要因素为测量的重复性。The uncertainty of measurment to oxygen bomb calorimeter, differential scanning calorimeter, water gas - flow calorimeter were evaluated. The sources of every uncertainty component was analysed. The results evidenced that the main influence of measurment uncertainty was measurent repeatability.
