摘要
阐述了量热仪的热容量标定对热值准确测定的重要性,并对影响量热仪热容量标定结果的因素进行分析,指出应选择热容量与温度都能在合适范围内的量热仪,并采取适当增减试样的称样量或苯甲酸的量及改变量热仪程序等措施以减少对发热量准确测定的影响。
The importance of accurate determination of calorific value to the heat capacity calibration of calorimeter was described, and the influencing factors of heat capacity calibration of calorimeter were analyzed in this paper. It was pointed out that the calorimeter with temperature and heat capacity in appropriate range should be selected, and the measures such as adjusting the quantity of coal sample or benzoic acid appropriately and improving the program of calorimeter should be adopted to reduce the influence on the accurate determination of calorific value.
