Making aluminum also releases super potent greenhouse gases, called perfluorocarbons.

制造铝还会释放超强温室气体，称为全氟化碳。

To get around the first problem, scientists studying liquid ventilation work with liquids made up of perfluorocarbons, or PFCs, instead of water.

为了解决第一个问题，研究液体通风的科学家们使用由全氟化碳或 PFC 组成的液体代替水。
