摘要
研究了不同种类和浓度电解质溶液调制的Ca-蒙脱和Na-蒙脱石试样的（001）晶面间距与电解质种类和浓度的关系，进而阐述了蒙脱石品体胀、缩的渗透压作用机理。该机理较以往的理论更好地解释试验观察到的现象。
In the Paper, the relationship between the space d001 of Ca-, Na- Montmorillonite samples and the kinds and concentrations of salt solution in samples are studied, and the mechanism of osmotic pressure action on expansion and shrinkage of the Montmorillonite crystal are also presented, which can give a better explanation than other theories to the phenomena of expansion and shrinkage of crystal observed in lablotory tests.
