依时计量学反应与非依时计量学反应李汝雄（北京石油化工学院化工系１０２６００）化学反应计量式一般表示反应物与产物间的计量关系，总的计量式中不出现反应中间物。如反应步骤中出现中间物，由于中间物的积累，且随时间变化，反应物与产物的量间的关系在反应过程中将不...
Time-based Metrology and Non-Time-Based Metrology LI Ru-xiong (Department of Chemical Engineering, Beijing Institute of Petrochemical Technology 102600) The chemical reaction equation generally expresses the relationship between reactants and products. The reaction intermediates do not appear in the overall formula. If the intermediate appears in the reaction step, the relationship between the reactant and the amount of product will not react during the reaction because of the accumulation of intermediates and over time ...
