The degree of acidity or alkalinity of any solution, then, can be most conveniently expressed by the PH system. 因此,任何溶液的酸碱度都可以用PH体系来表示。采用这种方法极为方便。
The results showed that the fermentation degree was amended and raised when the alcoholicity was 8% and the proportion of persimmon and cornstarch was 3:1; and that sugar content reduced and acidity raised. 结果表明,发酵过程中,酒精含量为8%、柿子:玉米淀粉为3:1时可以改善和提高发酵程度,使糖度降低,酸度升高。
A comprehensive target with quantitation for mirror the evolutive segregation degree of a MAGMA-THE index of acidity and series of rocky acidity 一种反映岩浆演化(分异)程度的定量化综合指标&酸度指数(AI)和岩石酸度系列
The author deems that TSP concentration in atmosphere can not only indicate pollution degree of atmospheric particle contaminants, but also reflect the acidity and alkalinity of atmospheric precipitation, explain the cause of its acidity and alkalinity formation and forecast its acidity and alkalinity in advance. 据此认为大气中的TSP值不仅可以用来表示大气环境的颗粒污染物的污染程度,而且还可以用来反映大气降水的酸碱程度、解释大气降水酸碱性成因以及提前预测预报大气降水的酸碱性。
