本文扩展了已有的蒸发模型，用它模拟蒸发作用下浅层地下水中氟与其它组份的演化富集过程，并以氯离子作为蒸发过程的追踪剂，采用浓度－浓度图法进行验证，其结果理论模型与实际拟合较好。
In this paper, the existing evaporation model is extended to simulate the evolution and enrichment process of fluorine and other components in shallow groundwater under the action of evaporation. Chloride ion is used as tracer for the evaporation process and the concentration-concentration diagram is used to verify the model. The results of the theoretical model and the actual fit better.
