heat history

In DSC measurements, the second heating run was used to eliminate the effect of solvents and heat history on glass transition temperature ( Tg), and also physical aging was used to improve the sensitivity of Tg measurements by enhancing the enthalpy endothermal peaks.

DSC法中采用二次扫描以消除溶剂和热历史的影响，并利用物理老化方法来增强N-烷基壳聚糖在DSC曲线上的玻璃化转变区域的热焓吸热峰，以克服DSC法的不灵敏性。

The reservoir time are decided by inclusion body homogeneity temperature and terrestrial heat history, the time is the telophase of the Cretaceous period, the reservoir time and tectonic movement is accordant.

利用烃类流体包裹体均一温度并结合盆地东部的地热史，厘定出石千峰组气藏成藏时间为晚白垩世，这与盆地整体向西倾斜、地层大量剥蚀的时间基本上是一致的。
