摘　　要：合成了 Ｎｉ（ Ｃ１０ Ｈ８ Ｏ５ Ｎ２）·２ Ｈ２ Ｏ，用元素分析、红外光谱、热重及差热分析对该配合物进行了表征，并对其热分解过程进行了研究，运用 Ａｃｈａｒ 法和 Ｃｏａｔｓ－ Ｒｅｄｆｅｒｎ 法，推断出该配合物第三步热分解的非等温动力学方程．The complex Ni(C 10 H 8O 5N 2).2H 2O was prepared, its structure was assigned on the basis of element analysis, IR, moler conductauce. And its kinetics of thermal decomposition was studied under non-isotherml condition with TG. The possible equation of non-isthermaal kinetics at third step is suggested by the Achar method and the coats-Redfern method. The kinetic equation may be expressed: d α /d t = A e -E/RT 3/2(1- α ) 4/3 [(1- α ) -1/3 -1] -1 .
