摘　　要：利用差示扫描量热法(DSC)测试了三羟甲基乙烷(PG)和三羟甲基氨基甲烷(TAM)二元体系的贮热性能包括相转变温度和相变焓。利用步冷曲线法研究相交与时间的关系,从而证明周-固相变符合阿仑尼乌斯方程,计算得到相变反应级数和表观活化能。DSC method was used to study binary mixtures pentaglycerine （PG） and tris （hydroxymethyl）amnomethane （TAM） of phase transitions for thermal energy storage.,which were include transitions temperature and transitions enthalpies . Step-cooling curve method was used to study the relation between transitions phase and time, then prove that the solid-solid phase transitions were accord with the Arrhenius equation and determine the reaction order of phase transitions and activation energy.
