A study in the US has identified the prime factors that drive the fizzy plumes from Coke bottles: the roughness of the sweet and how fast it plummets to the bottle's base.
美国进行的研究指出了那些引发可乐瓶里嘶嘶作响的泡沫产生的主要成因:糖的粗燥程度和他们垂直落至瓶底的速度。
Theories abound as to why this happens, with some bloggers speculating that it is an acid-base reaction because Coke is acidic.
一些blogger们深思后得出了解释这一现象的原因的理论——这是种酸碱反应,因为可乐是酸性的。
Measurements of the pH of the Coke before and after the experiments showed that its acidity did not change, ruling out the idea that a simple acid-base reaction drives the fountains.
经过测量反应前和反应后实验前后的可乐pH值发现前后酸性没有发生变化,排除了简单的碳酸反应导致这喷泉影响的想法。
