摘要：

By means of in situ microscopy we have studied the irreversible aggregation of colloidal polystyrene particles induced by an external alternating electrical field, and observed a crossover from reaction-limited aggregation to diffusion-limited aggregation (DLA). In the DLA stage the time-dependent cluster-size distribution obeys dynamical scaling. A physical explanation is given.
