摘　　要：用差示扫描量热法研究了溴化轻稀土丙氨酸配合物的非等温热分解过程,用Ozawa法、K issinger法、Achar微分法及Coats-Redfern积分法计算了配合物的热分解动力学参数(E和A),确定了升温速率为10℃/m in时配合物热分解第1步、第2步的反应机理函数。The non-isothermal decomposition kinetics of complexes of light rare earth bromides with alanine was studied using DSC technique. The kinetic parameters（activation energy E, pre-exponential factor A） were obtained from the analysis of the DSC curves by means of Ozawa method, Kissinger method, Achar method, and Coats-Redfern method respectively. The most probable mechanism functions were suggested by comparing the kinetic parameters.
