Nowak如今正在研究这个系统的化学动力学，也就是将描述带有不同序列的串的生长规律。

Nowak is now studying the chemical kinetics of this system, which means describing how strings with different sequences will grow.

但是直到天然气和石油的价格大幅上涨之后，全球化学工业才有了开展煤炭气化业务的动力。

But there had been little incentive for the global chemical industry to gasify coal until prices began soaring for natural gas and oil.

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。

So, let's look at dynamics, reactions between chemicals.

因此，我们来看看化学品之间的反应动力学。
