这个原子反应堆使用了一种气态冷冻剂。

The atomic reactor used a gas coolant.

在冷冻系统中，液体冷冻剂快速蒸发而吸热产生冷却效果。

In a refrigeration system, the cooling is produced as the rapid evaporation of the liquid refrigerant absorbs heat.

照宝马的汽车架构主管汉斯·拉特·格贝尔说法，这里大多数诸如鼓捣鼓捣空气动力学或即时泵入冷冻剂这种小改动。

These are mostly "easy things" like fiddling with aerodynamics or pumping coolant "on demand", says Hans Rathgeber, BMW's head of vehicle architecture.
