摘　　要：利用TG DTG DTA热分析技术 ,研究了N ,N’ 双 (氨烷基 )草酰胺合铜 (II)配合物在动态空气气氛中的热稳定性 ;结合微分法 (Achar法 )和积分法 (Coats Redfen法 )协同处理非等温TG数据 ,通过对比热分解动力学参数E和lnA ,提出了配合物热分解反应机理 ;The thermal stability and the thermal decomposition kinetics of N,N' bis substitutive (alkylaminoalkyl)oxamidocopper(II) complexes under dynamic air atmosphere ware studied by TG, DTG and DTA technique. The non isothermal kinetics data were analyzed by means of the Achar method and the Coats Redfen method. The possible kinetic model function was suggested by comparison of the kinetic parameters. The mathematical expressions of E and ln A were derived from the kinetic compensation effects.
