求翻译：小颗粒的存在虽然增加了碰撞频率，但其所携带的热量有限。因此随着颗粒浓度的提高尤其是大颗粒浓度的提高，小颗粒的强化换热的作用越来越不明显。是什么意思？

The presence of small particles, despite an increase in collision frequency, but the heat they carry is limited. With the improvement of the particle concentration, especially the improvement of the concentration of large particles, small particles of the role of enhanced heat transfer more and more

Although small particles of the collision frequency increase, but their limited heat. Thus, with increasing concentration of particles in the particle concentration is increased, the small particles of the enhanced role of the heat exchange is not growing.

Although the finely ground particles existence increased the collision frequency, but its carries the quantity of heat is limited.Therefore along with the pellet density enhancement big pellet density enhancement, the finely ground particles strengthened heat transfer function more and more is not i

Despite an increase of small particles collision frequency, but they carry a limited amount of heat. So as the concentration increases, especially a large improvement of particle concentration, heat transfer enhancement of the role of the small particles is less and less obvious.
