这学期我们随后会讨论燃料电池，当我们讲到，关于氧化还原反应和电化学单元时。

And, we'll talk about fuel cells later in the semester when we do the unit on REDOX reactions and electrochemistry.

项目目标：将微生物与电化学催化系统结合起来，利用氢气和二氧化碳生产丁醇，再利用化学方法将丁醇转化为航空燃料。

Project Goals: Develop a combined microbial and electrochemical catalytic system that converts hydrogen and carbon dioxide into butanol, and find a chemical method to convert butanol into jet fuel.

上面的译文便犯了定义过宽的错误。 试译：腐蚀是金属（如低碳钢）返回其天然状态（如氧化铁即铁锈）的电化学过程。

Corrosion is an electro-chemical process by which a metal such as mild steel ,returns to its natural state ,state ,such as iron oxide or rust.
