石油焦炭是一种燃料,是由石油提炼过程中的副产品加工而成的.

Petroleum coke is a fuel produced using the byproducts of the petroleum refining process.

最近在分子图形上的发展，使我们具有可从分子组成数据中预测提炼过程有效性的能力。

Recent development in molecular modeling provides us with abilities for prediction of effectiveness of refining processes from the molecular composition data.

所以“移置“是一种滞后的，迂回的理解，而另一方面，“凝缩“，则是理解的提炼过程。

So displacement is a kind of delay or detour of understanding, and condensation, on the other hand, is a kind of distillation of understanding.
