Effects of Interparticle Potential on the Sedimentation of Monodisperse Colloid System
粒子间势力对单分散稳定系统粒子沉降的影响

The effects of interparticle potential on the sedimentation of colloid system is still anunsolVed problem. An important difficult problem is how to formulate the interparticle potential in astable system. People can only depend on some models now. Here we investigate three previous modelsof interparticle potential and present a new and more reasonable method to deal with the interparticlepotential in monodisperse system. Moreover;; some numerical calculations are made and the results arecompared with experiments. The comparison shows that the new method is better than the previousones.
