ASTM E1269-01《Standard Test Method for Determining Specific Heat Capacity by Differential Scanning Calorimetry》里说:
“12.4 The specimen should be held at the starting temperature for several minutes before initiation of the temperature program. An equilibrium time of four minutes is suggested. However, other equilibrium times may be used but shall be reported.”
只是为了保证测试时仪器状态稳定,便于计算吧。

第一个恒温段可以理解为保证稳定,但后一个恒温段似乎没什么用处
