本文讨论了水流式手动热量计测定燃气热值的误差,包括系统误差,未定系差和随机误差。测量值经校正值修正后,系统误差基本消除。未定系差和随机误差构成最终的不确定度。按照“标准”规定的方法操作,最终不确定度约为2％。
This paper discusses the error of the determination of gas calorific value by flow-type manual calorimeters, including systematic errors, undetermined and random errors. After the measured value is corrected by the correction value, the systematic error is basically eliminated. Uncertainty and random errors constitute the final uncertainty. According to the method specified in the “standard”, the final uncertainty is about 2%.
