The sorption kinetics included the initial fast phase and the final slow phase. The first-order kinetic reaction and double constant rate equation could describe the sorption kinetics well.

吸附动力学过程包括吸附快反应阶段和慢反应阶段，可用动力学一级方程和双常数速率方程描述；

Because the kinetics of Beckmannrearrangement is very complicated and the reaction speed is very fast, the realization of its reaction kinetics is very variant.

由于贝克曼重排反应的机理非常复杂，而且该反应速率极快，因此对其机理的认识很不一致。

So, that's kinetics -- how fast a reaction will go, and from the perspective of someone who's a biochemist, I'm interested in kinetics and enzyme kinetics, and thinking about molecules that catalyze reactions in the body.

所以这就是动力学，一个反应发生的有多快,从一个生物化学家的角度,我喜欢研究动力学,酶动力学。
