| 摘 要： | 根据热动力学基本理论，建立了简单级数反应热动力学对比参量方程，提出了一种确定反应速率常数的方法－半寿期法，该法只需要特征时间参量ｔｍ及相应的热谱数据便可方便地计算化学反应的半寿期和速率常数，通过几个简单级数反应体系的热动力学研究，验证了半寿期法的正确性。 |

| Abstract: | According to the theoretical basis of thermokinetics and chemical kinetics, the thermokinetic reduced-parameter equation for simple order reaction has been derived and a novel thermokinetic method for determining the rate constant,the half-life time method has been proposed in this paper. This method only needs the characteristic data(tmand φm) of one thermoanalytical curve and conveniently calculates the half-life times and the rate constants of studied reaction systems. In order to test the validity of this method, several reaction systems with simple order have been studied. The experimental results indicate that the half-life time method for simple order reaction is correct. |
