Based on a great number of numerical calculations of the repulsion between two inclined platy clay particles, explicit empirical formulae for estimating electric double-layer repulsion between clay particles are put forward. Comparison between the empirical solutions and corresponding numerical results shows that the proposed formulae have a reasonable accuracy, and application of the presented formula is easy and efficient. 关键词：CLAY PARTICLES Electric DOUBLE-LAYER REPULSION NUMERICAL analysis Empirical FORMULA
