一、差熱分析儀相關簡介:
Differential thermal analyzer:
差熱分析(DTA)是在程序控制溫度下,測量物質和參比的溫度差和溫度關系的一種技術。當試樣發生任何物理或化學變化時,所釋放或吸收的熱量使試樣溫度高于或低于參比物的溫度,從而相應地在差熱區線上可得到放熱或吸熱峰。差熱曲線(DTA)是由差熱分析得到的記錄曲線。曲線的縱坐標為試樣與參比物的溫度差(△T),向上表示放熱反應,向下表示吸熱反應。差熱分析也可以測定試樣的熱容變化,它在差熱線上發映出基線的偏離。
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.
