本文报导了一种绝热式自动量热计.用“双光笔记录仪”实现了自动控制绝热条件,自动记录热交换图谱,自动记录初期和末期的温差及主期的温度变化情况.由热交换图谱表明,主期中量热系统与热屏之间的温差可保持在±0.005℃以内。实验测定了量热系统的空当量和水当量,两者的偏差不大于0.1％.实验证明,量热容器内发生的热效应与光笔记录曲线的峰高成正比.光笔移动一毫米相当于0.1卡左右的热效应,测量的相对精度为0.6％.
In this paper, a kind of adiabatic calorimeter is introduced.Automatic control of adiabatic condition is realized by “dual light pen recorder”, the heat exchange profile is automatically recorded, the temperature difference between the initial and final stages and the temperature change in the main stage are automatically recorded, Atlas shows that the temperature difference between the main calorimeter system and the hot screen can be kept within ± 0.005 ℃. Experimentally measured the calorimetric system of empty equivalent and water equivalent, the deviation between the two is not more than 0.1% .Experimental results show that the calorific value of the thermal effect within the container is proportional to the peak height of the light pen record curve. About the thermal effect, the relative accuracy of the measurement is 0.6%.
