n.洒水装置；洒水车

The ground floor commercial space in a new residential building had a low ceiling and a tangled maze of plumbing, sprinkler and electrical conduits serving the residences above. 这家位于一座新的住宅楼底部的商业空间，天花板较低，上面布满了复杂的铅质管道，洒水装置以及电线管道系统，这些管道为整个居民楼服务。

A sprinkler passing by,I was dashed with water. 一辆洒水车驶过，洒了我一身水。

The use of automatic fire sprinkler systems fits into this category.Once the fire has started, the sprinklers operate to reduce the impact of the fire. 自动洒水灭火装置就是个例子，火灾一旦发生，洒水车立即去灭火。
