【摘要】 热分析是一种常用的分析技术。本文介绍了用微型计算机与ＤＴＡ－ＴＧ，ＤＴＡ，ＤＳＣ，ＴＧ等热分析仪构成的热分析数据处理系统的工作原理、软件功能及数据处理方法，并给出ＣａＣ２Ｏ４·Ｈ２Ｏ热分解过程的实测数据，其结果与理论值相当接近。更多还原

【Abstract】 hermal analysis is one of analytical technique frequently used. This paper presents a data processing system based on microcomputer which is used for the Differential Thermal Analysis (DTA), Differential Scanning Calorimetry (DSC), Thermogravimetry (TG) and Differential Thermal A nalysis- Thermogravimetry (DTA-TG). The system can be operated on the IBM PC computer.The principle and function of system and method of data processing are described. The test results for CaC2O4·H2O are given and close to the theoretical values with satisfaction.更多还原
