DTA的含义没有弄清楚吧！
DTA原理是：物质在升温或者降温过程中，由于内部发生物理或者化学变化，将有能量的释放或者吸收，宏观表现为升温（降温）过程被改变，在温度记录图纸上体现出来的就是峰值。这个现象也 ...

In DTA, the heat flow to the sample and reference remains the same. The variable is the temperature difference between the sample and reference. When the sample and reference are heated identicall ...

DTA的衍射峰面积也是熔化潜热。
其实DTA与DSC用原理是一样的，只不过相对于DTA，DSC的分辨率更高，精确度更高，带有解析功能。
