The change of average size of products along the radius at the exist of reactor has also been calculated. The calculated results indicate that the residence time is longer, the average size of products is larger, but the distribution of size is narrower, tending to self-preserving distribution; when the concentrations of reactants increase, the average size of products becomes larger, but the distribution of size becomes narrower; the gradients of reactants are greater, the average size is larger; the increasing of reacting temperature will cause the size of product to be larger under same residence time. The average size of product at the exist of reactor varies along the radius, has a maxim value.
