摘　　要：合成了氯化铽与L-酪氨酸和甘氨酸的三元固态配合物,并用TG-DTG技术研究了配合物的热分解过程.采用微分法中的Achar法和积分法中的Coats-Redfern法对热分解的非等温动力学数据进行了分析,推测出了可能的热分解反应机理,求出了反应的表观活化能.The ternary solid-state complex Tb(Tyr)(Gly)3Cl3???????????3H2O (s) has been synthesized with TbCl3??????????6H2O(s), taking Tyr and Gly as reactants.The thermal decomposition processes of the complex have been studied by use of TG-DTG technique. The non-isothermal kinetic data has been analyzed by employing of the Achar method and Coats-Redfern method. The possible reaction mechanism was suggested and the apparent activation energy of the reaction was obtained.
