摘　　要：综述了TG-DTA技术在类水滑石化合物热分解过程中的应用。对TG-DTA曲线上的失重台阶数、峰的个数及失重过程所对应的温度范围进行了理论阐述,借助有关原理,对相应类水滑石化学式的推断、热分解过程动力学参数的计算及热分解机理推断等方面进行了较为深入的探讨,从而全面获悉了类水滑石化合物的热分解行为。In this paper, the main application of TG-DTA technology in the thermal decomposition of hydrotalcite-like compounds was reviewed. The number of weight-loss stages and the peak on the TGDTA figure and the temperature corresponded to the weight-loss procedure were represented. Based on relevant theories, the deduction methods of hydrotalcite-like compounds＇ chemical formulation, the calcu- lation methods of kinetics parameters and the mechanics corresponded to thermal decomposition procedure were discussed in detail. Thus, the thermal decomposition behaviors were learned in an all-around way.
