吸管 Drinking straw(重定向自Drinking Straws)
![]() ![]() ![]() ![]() 吸管(英语:drinking straw),或称饮管,部分翻译文献根据英文直译为麦管,是一条圆柱状,中空的塑胶制品,其主要功用是用来吸取杯子中饮料,也有用来吸食一些烹饪好的动物长骨的骨髓。一般直径在0.5cm左右,但是用来吸食酸奶、珍珠奶茶等饮品时,会用较粗的吸管,有的直径有1.5 cm。 吸管能吸取饮料、食物,是运用「让吸管内的气体压力小于吸管外的大气压力」之原理,来吸取饮料与食物。使用时对着吸管吸走部分空气,将造成管内压力变小,此时吸管外的大气压力>吸管内的气体压力,于是大气压力将会迫使管内液体上升。当嘴巴离开吸管,因为管内气体与外界的气体得到链接而连成为一体,所以管内气体压力=大气压力,因此没有多余的压力可将吸管内的饮料往上推升,吸管内的液体便会下降。同样的,若吸管的管壁上有破洞,若吸取饮料时管壁破洞与大气有所接触,此时管内气体与外界的气体得到链接而连成一体,造成管内气体压力与大气压力的大小相同,就不易将饮料吸起。

Drinking straw 吸管(重定向自Drinking Straws)
![]() ![]() ![]() ![]() A drinking straw is a short tube for transferring a beverage from its container to the mouth of the drinker. A thin tube of plastic (such as polypropylene and polystyrene) or other material, straight or with an angle-adjustable bellows segment, it is used by being held with one end in the mouth and another end in the drink. Muscular action reduces air pressure in the mouth and above the liquid in the straw, whereupon atmospheric pressure forces the beverage through the straw. |
