摘　　要：在热动力学理论基础上提出了一种新的热动力学研究法时间变量法．该法无须将反应进行到底，只需知道一张热谱图上的３个时间点ｔ，ｔ时刻峰高Δ和ｔ前峰面积ａ，就可用计算机数值方法求算反应的速率常数．应用该法研究了一级反应、等浓度二级反应、不等浓度二级反应、三级反应和１．５级反应的热动力学．On the theoretical basis of thermokinetics proposed in previous articles, a novel thermokinetic research methodtime variable method, has been proposed in this paper. The method only needs three time points t i , peak height Δ i at t i and peak area a i before time t i . It does not require the thermokinetic reaction to be completed. The rate constants were obtained by data processing on computer. In order to test the correctness of the method, first order reaction, second order reactions(with equal concentrations and unequal concentrations, respectively), third order reaction, 1 5 order reaction have been studied. The rate constants are quite in agreement with those in literature. Time variable method is believed to be correct.
