聚对苯二甲酸乙二酯的熔融分析准等温，温度调制差示扫描量热法。通过在熔化范围（± 1.0 K）内正弦地改变温度来进行测量。在熔化范围内，样品的一小部分可逆地熔化。该观察结果被认为是对特定大分子熔融可逆性的直接观察，只要它们仅部分熔融并且不需要分子成核进行重结晶。
The melting of poly(ethylene terephthalate) is analyzed by quasi-isothermal, temperature-modulated differential scanning calorimetry. The measurement is done by sinusoidally changing the temperature in the melting range (± 1.0 K). In the melting range a small portion of the sample melts reversibly. This observation is taken as a direct observation of the reversibility of melting of specific macromolecules as long as they are melting only partially and need no molecular nucleation for recrystallization.
