dx/dt	stands for a rate of conversion;
x	stands for the conversion of the reaction, which is defined as x =(w0 − wt)/(w0 − wf), where w0 and wf stand for the initial and final masses of the sample at each stage of decomposition (mg), respectively, and wt stands for the mass of the sample at time t (mg);
f(x)	stands for a differential mathematical model function of kinetics, which depends on the reaction type and mechanism;
g(x)	stands for an integral mechanism model function of kinetics, which depends on the reaction type and mechanism;
k(T)	stands for the temperature-dependent rate constant, which can be described by the Arrhenius equation;
A	stands for the preexponential factor (min−1);
R	stands for the gas constant 8.314 J·(mol·K)−1;
E	stands for the apparent activation energy (kJ·mol−1);
T	stands for the absolute temperature (K);
Β	stands for the heating rate (K·min−1);
Tp	stands for the absolute thermodynamic temperature at which the weight loss rate reaches a maximum value (K).
