二、关联题(每组关联题题干下有 4个小题，每小题4个选项) 第一组：
The CO 2 fire extinguishing installation may incorporate a smoke sampling system so that fire can be detected in the early stage at the smoke detecting cabinet, which is situated in the wheelhouse. Each cargo compartment is individually connected to the smoke detecting cabinet with small bore piping and, by a suction fan mounted on the wheelhouse roof, samples of the air in each cargo space are continually drawn up to the smoke detecting cabinet and discharged into the wheelhouse or the
atmosphere through a diverting valve. Thus smoke from a fire in any cargo space can be immediately detected.
