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。
Buffer Solution usually containing a weak acid and its conjugate weak base, or a salt, of such a composition that the pH is held constant within a certain range.
通常指含有一种微酸和与之结合的一种微碱或盐，并能维持酸碱值基本恒定的溶液。
The variation of this pH range was dependent on the strength of the base, the volume of the conjugated acid cation, and whether this cation can increase the surface charge of the micelles or not, etc.
这一范围的大小（宽窄）受制于碱的强弱、共轭酸阳离子的体积以及共轭酸阳离子是否能增加胶束表面的电荷等几个方面。
