摘要/Abstract

摘要： 在文献[10]、[12]的基础上,研制了一种能在常温到150°C的较大温度范围内工作的“RD-Ⅰ型热导式自动量热计”。本文报导了仪器结构和工作原理。通过电能测定,证明仪器设计合理,工作正常。其性能完全符合Tian氏方程的要求。而且重现性好(相对精度为0.5%—1%左右),灵敏度高(对1卡以上的热效应能够准确地进行测量)。量热计通过光笔记录仪实现了测量记录的自动化。

Abstract: 1. On the basis of our previous works, a conduction type calorimeter, is constructed which is automatized with a photo-pen recorder. It behaves well in a wider temperature range between ambient to 150℃.2. The heat constant of this calorimeter is calibrated with electric energy and the constants at 100℃ and 150℃ are reported in this paper. From these experimental results, this calorimeter is believed to be in conformity with Tian's equation.3. The sensitivity of this calorimeter is high enough for the measurement of the heat evolved by a chemical reaction. The heat of one calorie can be measured with a relative standard devivation of about 0.5% to 1%.
