On the foundation of experimental results of thermokinetics, a general analog thermogram equation, Delta = alpha te(-k beta t) which can simulate the thermograms of chemical reactions with simple order, has been proposed in this paper. Combined with the basic theory of thermokinetics, a novel studying method of thermokinetics, the analog thermogram method, has been developed, The formulae for calculating kinetic parameter K-n and rate constant k(n), which do not involve any instrument constants, have been derived, The expression of the cooling constant of thermokinetic system has been obtained at the same time, The analog thermogram method can be applied not only to studying slow chemical reactions, but also to studying faster ones, In order to lest the validity of this method, the saponifications of ethyl propionate and ethyl benzoate in aqueous ethanol solvent, the saponification of ethyl butyrate in aqueous solution, the substitution of benzyl chloride in aqueous DMSO solvent, the formation of hexamethylenetetramine in aqueous solution, and the polymerization of acrylamide have been studied, The rate constants calculated with this method are in agreement with those in the literatures, and therefore the analog thermogram method is believed to be correct.
