这些集管通过空气管线与抽真空系统相连，以便从空冷凝汽器内抽走不可冷凝的气体。
These manifolds are connected to the vacuum system through air take-off lines in order to remove the non-condensable gases from the condenser.
发明者说，这意味着当冷凝的水汽聚集在一起时，会形成一层不可见的薄膜，而不是雾气，镜片依然会很清晰。
Their inventors say this means that when condensation gathers, it becomes an invisible film rather than fog, leaving the lenses clear.
第三十五章，冷凝器，增加了水冷与空冷的对比，还有生物控制、制冷凝器、助电动机和不可压缩（体）清洗的信息。
Chapter35 condensers has added a comparison of watercooled versus air-cooled condensers and information on biological control brazed condensers pony motors and purging noncondensables.
