| 摘 要： | pH值是溶液酸碱性的量度。首先定义为氢离子浓度负对数。在使用过程中发现此值与实验值有一定的偏差，特别是浓度偏大时，误差就更大。因此，为精确描述pH值，就须用活度来代替浓度，从而使pH值更接近于实验值。

| Abstract: | The PH value is a measurement of acid and alkali. It is firstly defined as minus logarithm of PH indicator. In the application process, the writer of this paper finds that there is some deviation between the value and experimental value, especially when the concentration is great. Therefore, to precisely describe PH value, it is necessary to replace concentration with flexibility so that the PH value is closer to the experimental value. |

| Keywords: | PH value degree of flexibility coefficient of flexibility intensity of ion |
