摘　　要：根据热导式量热计的理论基础——Ｔｉａｎ′ｓ方程，将时间作为已知参量，提出了一种新的热谱数据解析方法——简单级数反应的热谱面积比法．应用该法研究了几种简单反应的热动力学，实验结果验证了热谱面积比法的正确性．On the basis of thermokinetic theories,a novel data processing method for simple order reactions——thermogram area ratio method,was proposed.In order to test the validity of this method,the saponification of ethyl butyrate and ethyl benzoate in aqueous ethanol solvent and the formation of hexamethylene tetramine in aqueous solution were studied.The rate constants calculated by this method are in agreement with those reported in the literatures.Therefore,the thermogram area ratio method is belived to be correct.
