摘要： 对求算球型胶体颗粒相互作用能的Derjaguin法进行了适当的修正,并由此得出简单的解析表达式。对低电位条件下等同和不等同球颗粒的计算结果表明,该法拓宽了Derjaguin公式的应用范围,提高了计算结果的精确度。

Abstract: The correction to classical Derjaguin method has been made in the formulae for the double layer interaction at constant surface potential between two identical and between two dissimilar spheres.The expressions which can be applied to any ka and kHare obtained, in which k is Parameter, a is the radius of particles, His the shortest distance between the two spheres.The improved Derjaguin approximation opens up a usual area of familiar Derjagain formulae, and gives the exact results.
