【摘要】 通过对煤飞灰微粒在声场中团聚实验研究的观测发现，团聚后的煤飞灰粒子并非为球形或近似为球形，因其特殊的形状，将其简化为当量球形来处理，模型预测结果与实际情况偏差较大。运用分形和分维理论对前人的团聚模型作了修正，用修正后的模型对煤飞灰微粒团聚作预测，并与前人的计算结果进行比较更多还原

【Abstract】 It was discovered that agglomerated coal flyash is not spherical in sonic experiments.Large deviation exists between the calculated results and the experimental ones if the particles are assumed to be equivalent spheres.The particles belong to fractal geometry in structure.So the authors used fractal geometry to modify the previous model.更多还原
