一、差热分析仪相关简介：

Differential thermal analyzer:

差热分析（DTA）是在程序控制温度下，测量物质和参比的温度差和温度关系的一种技术。当试样发生任何物理或化学变化时，所释放或吸收的热量使试样温度高于或低于参比物的温度，从而相应地在差热区线上可得到放热或吸热峰。差热曲线（DTA）是由差热分析得到的记录曲线。曲线的纵坐标为试样与参比物的温度差（△T），向上表示放热反应，向下表示吸热反应。差热分析也可以测定试样的热容变化，它在差热线上发映出基线的偏离。

Differential thermal analysis ( DTA ) is in the program control temperature, measuring physical and reference temperature difference and temperature relation of a kind of technology. When the specimen is any physical or chemical change, release or absorb the heat to make the sample temperature is higher or lower than the reference temperature, thus corresponding to the poor in hot line can be exothermic or endothermic peak. Differential thermal curve ( DTA ) is obtained by differential thermal analysis curve. The longitudinal coordinate for the sample and the reference temperature difference (△ T ), upward downward said exothermic reaction, said the endothermic reaction. Differential thermal analysis can also be used to test specimen heat capacity change, it indicates poor hotline baseline deviation.
