本文叙述了应用混合法测量298.15—1200°K 热函的大块型量热计。介绍了量热实验主期标准电阻电位降的计算方法及没有热函数据试样终温校正至298.15°K 的方法。测定了泡沫砖的高温热函,给出了热函～温度方程式:H_T—H_(298.150k)=0.21~4T+2.60×10~(-5)T~2-66.0 卡/克。讨论和分析了实验中出现的误差及对于量热计的改进意见。
This article describes the use of hybrid method to measure the 298.15-1200 ° K calorimeter bulk calorimeter. The calculation method of the standard resistance potential drop in the main period of calorimetry experiment and the method of correcting the final temperature of the sample to 298.15 ° K without the thermal function are introduced. The thermal enthalpy of foam brick was measured and the enthalpy-temperature equation was given: H_T-H_ (298.150k) = 0.21 ~ 4T + 2.60 × 10 ~ (-5) T ~ 2-66.0 cal / g. Discuss and analyze the error that appeared in the experiment and the improvement opinion to calorimeter.
