The chemisorption of aromatic molecules on transition metal is of great interest due to extensive use in petrol-chemistry industry and environment protection.
由於在石油化工和環境保護方麪的廣泛應用，芳香分子在過渡金屬表麪的吸附成爲人們研究的熱點。

And often, if you want to make a lot of it, you have to think about the thermodynamics of the system, how fast the reactions will go and kinetics, and then whether they'll go, the thermodynamics, and sometimes then you need to adjust the reactions, maybe use a transition metal to make it go better.
這種分子就不能正常工作，而且通常來說,如果你要大量生産一個東西,你必須考慮系統的熱力學，反應速率和動力學,還有反應是否會發生，熱力學，而且有時候你需要調整反應的發生。
