摘　　要：引入“对比进度”的概念,建立了可逆反应动力学新的数学模型,提出了可逆反应动力学的对比进度研究法.并用热导式自动热量计研究了一个可逆反应体系,计算结果与文献值符合甚好,验证了数学模型及对比进度法的正确性.A new concept,reduced extent of reaction,is introduced in this paper.Somenew mathematical models of reversible reaction kinetics are suggested,and a reducedextent method for study of the thermokinetics of reversible reaction is proposed.Areversible reaction system,tris(hydroxymethyl)aminomethane with nitroethane inwater(μ=1.0),has been studied with this method at 30.0℃.Rate constants andequilibrium constant calculated with this model are in fair agreement with that givenin the literature.Thus,the correctness of the models and the validity of this methodare proved.
