exhaust vent

基本解释

Note the large exhaust vent.
注意那个大的排气孔。
On the roof, overlooking the activity, Michael crouches behind an exhaust vent to stay hidden from the helicopter.
在屋顶上，Michael俯视着他们的行动，一架直升机飞过，他蹲伏在一个排气口处以免被发现。
In a minute you'll be able to dry off in the still warm bathroom, but the heat from the hot water will now be in your home instead of up the exhaust vent.
不一会，你就会在仍然温暖的浴室内弄干，但是热水中的热量现在在你的家中而不是从排气孔中跑掉。

You know, kind of like when Sidney Bristo (Alias) is racing down an exhaust vent to 'disarm' a satellite gizmo on a random rocket just before the launch and therefore the utter distruction of the world but the rocket they show is the Saturn V used in the Apollo program.
