假设微生物的失活是由于细胞的“关键结构”与另一种反应物分子之间的化学反应造成的，则可以将反应速率的数学模型应用于该过程。考虑到化学反应的化学计量方程，微生物的热死亡或消毒可以通过艾林模型的扩展来描述。扩展模型不仅适用于热灭活，还适用于消毒动力学和 pH 值的影响。考虑到水活度对热破坏的影响，对扩展模型进行了实证修正，并拟合了大肠杆菌热破坏的实验数据。
Assuming that the inactivation of microorganisms is due to a chemical reaction between a ‘critical structure’ of the cell and another reactant molecule, mathematical models of the reaction rates can be applied to the process. Considering the stoichiometric equation of the chemical reaction, the thermal death or disinfection of microbes can be described by an extension of the Eyring's model. The extended model is applicable not only to heat inactivation, but also to disinfection kinetics and to the effect of pH. Taking into accout the effect of the water activity on heat destruction, the extended model has been modified empirically and fitted to experimental data on the heat destruction ofEscherichia coli.
