在化学动力学中,稳态近似和平衡态近似是处理复杂反应机理的两种常用方法。提出这两种方法已有数十年历史了,但有关它们的特性,应用条件以及相互关系的论述仍是混乱的。例如,对于稳态近似,有把中间物浓度远小于反应物浓度,且不随时间而变作为两 In chemical kinetics, steady-state approximation and equilibrium approximation are two common methods for dealing with complex reaction mechanisms. Both of these methods have been proposed for decades, but the discussion of their characteristics, application conditions, and interrelationships is still confusing. For example, for a steady-state approximation, the concentration of the intermediate is much less than the concentration of the reactants and does not change over time as two
