摘要： 利用热重分析法分别选取热塑性仿真植物的花、叶、茎三部分为研究对象进行热解动力学的研究。利用Coats-Redfern法和Gorbatchev法选取反应最佳机理函数建立模型，确定其活化能和指前因子并比较两种方法的准确性。结果表明：在氮气氛围下，仿真植物花和叶两部分的热解为一个阶段，茎的热解可以分为两个阶段，茎的热稳定性最低，叶的热稳定性最高。采用Gorbatchev法得到的仿真植物三部分试样的反应活化能更为精确。

Abstract: Thermogravimetric analysis was used to analyzed the pyrolysis kinetics of the flowers, leaves and stems of the thermoplastic artificial plants. Coats-Redfern method and Gorbatchev method were used to select the optimal mechanism function model to establish the model. The activation energy and pre-exponential factor were obtained and the accuracy of the two methods were compared. The results showed that the pyrolysis of the flower and leaf parts of the simulated plants was in one stage under nitrogen atmosphere, but the pyrolysis of the stems was in two stages. The heat stability of the stems was the lowest, and the heat stability of the leaves was the highest. The reaction activation energy of the simulated three-part sample obtained by the Gorbatchev method is more accurate.
