| 中文摘要: |
| 通过对小车河从阿哈水库大坝取水口至南明河入口段采集的水样进行pH值、温度及主要离子浓度测定分析，研究该段水体的水化学特征，并从溶解度方面初步分析，发现小车河“白水”现象是由于水中Ca2+浓度过高，使水体形成过饱和的CaSO4和CaCO3水溶液，析出大量白色CaSO4和CaCO3颗粒，与河水形成溶胶导致。 |

| It studied the chemical characteristics of water by measuring water sample′s pH,temperature and main ions′ concentration from the Aha lake reservoir outlet to the Nanming River entrance,and explored the causes of white water phenomenon from solubility aspect.The results showed that the white water phenomenon was due to the supersaturated solution of CaSO4 and CaCO3 formed in the river,which precipitates many white particles of CaSO4 and CaCO3,that forming the sol with the river. |
