Several typical surfactants are chosen to dispose superfine RDX particles alone or multiply. The dispersion of particles in water, the absorption michanism of surfactants on RDX particle surface and the double-electric layer properties of modified particles are studied by measuring the turbidity of the dispersion system and Zeta potential of the particles. And the surfactants are optimized.%选择了几种典型的表面处理剂，以单一或复合的形式对超细RDX粒子进行表面处理，通过测定分散体系的浊度以及粒子表面的Zeta电势，研究超细粒子在水中的分散性，以及表面处理剂在RDX表面上的吸附机理和吸附处理后粒子的双电层性质，并对表面处理剂进行优选。
