摘要：
Colloid particles have superlong-range attractive and repulsive forces. The distance between the secondary minimum of the potential energy of the interaction and the surface of the colloid is of the order of several mum and several tens of mum. These interactions clearly appear in the distribution of order-solution phase coexistence, in gathering particles to the ordered phase and in spontaneous pair formation. A new 'Dynamic electrical multipole model and resonance effect' is given. From this model, it is predicted that pairs will form in a shear field even in highly concentrated salt solution. Pair formation was observed after 24 hours as predicted.
