| 摘 要： | 运用Ｆｒｅｅｍａｎ－Ｃａｒｒｏｌｌ法和ＡＢＳ法两种热分析动力学模型，利用差示扫描量热法（ＤＳＣ）测定新戊二醇（ＮＰＧ）、三羟甲基氨基甲烷（ＴＡＭ）及其二元体系的低温固－固相变ＤＳＣ曲线，求算固－固相变的表观活化能和反应级烽，探讨表观活化能随组成不同的变化规律。两种方法处理的结果一致。

| Abstract: | Freeman Carroll and ABS kinetic methods were applied to determine the activation energy and the reaction order of the solid solid phase transitions in neopentylglycol(NPG),2 amino 2(hydroxymethy1) 2,3 propanediol(TAM) and their binary system by DSC curve. The changes of activation energy with the composition of the NPG/TAM binary system were studied and analysed. |
