| 摘 要： | 用热重（ＴＧ）及微分热重（ＤＴＧ）法系统地对中药阿胶的热降解全过程进行分析研究，结合阿胶的结构特征和热降解机理对各温度段分别进行分析和归属。提出了应用ＴＧ曲线的两个特征区和七个特征参数对阿胶的真伪进行鉴别的方法，结合ＤＳＣ实验结果，提高了判断的可靠性，为阿胶真伪鉴别提供了较简便、快速、可行的新方法。

| Abstract: | In this paper, the course of thermal decomposition of equus asins linnaeus was observed by thermogravimetry (TG) and derivative thermogravimetry (DTG). According to the structure of it, the thermal decomposition mechanism in distinct stage. On the basis of two characteristic regions on the TG curve and seven TG parameters, a new method to distinguish equus asins linnaeus has been advanced. |
