将“concentrator"翻译成中文

But so in here when there's electricity, the oxygen concentrator takes in room air.

但是当有电的时候 氧气集中器就采入室内空气

Neither concentrators nor cylinders are well suited to every situation, but a simple options assessment can determine which is better in each setting.

使用氧气浓缩器或氧气瓶应视当地情况而定,而进行简单的方案评估可作出更好的决定。
