摘要：

The structure of aggregates of bidisperse particles was probed with small angle light scattering. Various mixtures of nearly spherical hematite particles with diameters of 70 and 216 nm were induced to aggregate by the addition of KCI. The fractal dimension of the resulting aggregates was unable to be determined because of effects from the aggregate edges and short range non-fractal behaviour. Significant restructuring of the aggregates was found to occur as a result of pumping.
