在水文地质工作中,经常使用库尔洛夫的化学表示式来表示地下水的化学成分。作者在编写研究生论文时,曾经使用了另一种新的表示式—离子组合式。离子组合式实质上是库尔洛夫表示式的简化。表示的方法是先标出 HCO′_3+CO_3″、SO_4″、Cl′、Ca(?)、Mg(?)、Na(?)+K(?)等六个主要分析项目的毫克当量百分 In hydrogeological work, Kulov’s chemical representation is often used to represent the chemical composition of groundwater. The author used another new expression, ion-combination, in his graduate thesis writing. Ion combination is essentially a simplification of Korlof’s formulation. The method is to first mark the percentages of meq of six major analytical items such as HCO’_3 + CO_3, SO_4, Cl, Ca (?), Mg (?), Na (?) + K
