摘　　要：提出了可逆迁移过程和不可逆聚集过程共存的聚集体生长模型.假定聚集反应速率核为I(i;j)=2I,迁移反应速率核为K(i;j)=Jij或K(i;j)=Jj.建立Smoluchowski速率方程,由此求出了系统的集团浓度分布的精确解.结果表明,集团浓度分布符合标度特性.A kinetic model of the growth of aggregates driven both by reversible migration and by irreversible aggregation is proposed. Assumed that the aggregation rate kernel is while the migration rate kernel is or . Based on the Smoluchowski rate equation, we obtain the analytical solution of the aggregate size distribution. The results show that the aggregate size distribution approaches a conventional scaling form.
