Chemical characteristics of dissolved ions in the Nine Springs organic acid digest.

Median, mean, standard deviation (n = 13), and coefficient of variance (%CV). Ionic strength (IS)-calc’d and pH-calc’d were calculated by Visual MINTEQ. Units are millimole per liter, except for pH and %CV.

本数据集包含中位数、均值、标准差（n=13）以及变异系数（%CV）。其中计算得到的离子强度（IS）与pH值均通过Visual MINTEQ软件计算得出。除pH与%CV外，其余指标的单位均为毫摩尔每升。
