摘要
本文通过对有大量碳酸钙沉积河段的水质分析、野外观测，发现河水流动过程中将空气带入水中形成大量气泡，引起水体物化方面的迅速变化，包括碳酸钙大量沉积，笔者称之为掺气效应。通过野外实验，对掺气效应及掺气效应中水体物化变化和碳酸钙沉积速度进行了论证和研究，在此基础上提出：掺气效应是河流中碳酸钙大量集中沉积的一个主要因素。
Having analysed chermical composition of the water from river in which there are tufa deposited, and haying obsened process of tufa deposits in the field, the author discovers that aeration process or a speical kind of bubbule effect in flowing water led to formation of tufa deposits,After having verified several experiments both in the field and the laboratory and some useful data obtained. The autor holds that aeration effect in a main mechanism of tufa deposition.
