Popis v původním jazyce * :	A method of direct non-linear regression of the kinetic equation was proposed for a simultaneous calculation of the activation energy, frequency factor and reaction order from a single TG curve. The method of calculation was utilized for the kinetic parameters calculation from both the simulated and experimental curves (graphite and soot oxidation, Mg(OH)2 decomposition). The results were compared with the values obtained by traditional methods. A dependence of the calculated parameters on random errors of the experimental data was studied. The method of non-linear regression appears to be the best of the used methods from this point of view. It was proved that the proposed calculation method is as well applicable for the kinetic parameters calculation of more overlapping processes.
