释义
n.
A device that cools vapor back into liquid (as in a fridge or power plant)
冷凝器(如冰箱、电厂中将蒸汽变回液体的装置)
n.
(electrical, older term) a capacitor, a component that stores charge
(电学旧称)电容器
词根拆分
词根派生condense + -er(执行动作的东西)= 执行 condense 的装置。字面上是冰箱或发动机里把蒸汽变回液体的部件。电学义(capacitor 电容器的旧称)来自类比:它把电荷「聚拢压紧」。如今还能听到 'condenser mic'(电容麦克风),它用的就是电容器。
