摘要：
Rossini型气体热量计是目前测量准确度最高的气体热值测定装置，在研制过程中，量热容器的当量热容是实验装置的一个重要参数，采用电校正方法能够准确地测量其当量热容。为保证电校正实验与燃烧实验的一致性，实验中要做到电加热功率与燃烧功率完全相同，之后通过测量燃烧器周围吸热介质的温升分析得到量热容器的当量热容。实验结果表明：在电加热功率与燃烧功率一致的情况下，两种实验中燃烧器周围吸热介质的温升曲线完全吻合，测得量热容器的当量热容为19 023 J/K，当量热容测量不确定度为28 J/K，其相对不确定度为0.15%。

Abstract: The Rossini type gas calorimeter is the most accurate device in the current measurement of the heat capacity of the calorimeter. In the process of development, the capacity of the calorimeter is an important parameter about this experiment device. The experiment of electrical calibration can measure the heat capacity of the calorimeter accurately. In order to ensure the consistency of the electrical calibration and the combustion experiment, the power of electric heating is the same as the power of combustion exactly. The heat capacity of the calorimeter is analyzed by measuring the temperature rise of the heat medium. The results of two experiments show that the curves of temperature rise of the heat medium coincide when the electric heating power is the same as the burning power. The experiment determines the heat capacity of the calorimeter is 19 023 J/K. The uncertainty of the heat capacity of the calorimeter is 28 J/K, and the relative uncertainty is 0.15%.
