凝并是气溶胶颗粒的基本的现象之一,目前主要通过颗粒的凝并方程来描述这一物理过程。在颗粒凝并方程中,认为只要发生颗粒的碰撞便会发生颗粒的凝并,这种假设具有一定的局限性。针对这种不足,作者主要介绍了需要进一步考虑的影响因素,包括:颗粒间彼此存在作用力情况下的凝并;颗粒的回弹;颗粒自身属性的影响。 Condensation is one of the basic phenomena of aerosol particles. At present, the physical process is mainly described by the coagulation equation of particles. In the particle coagulation equation, it is considered that the coagulation of the particles occurs as long as the particle collisions occur, and this assumption has some limitations. In response to this deficiency, the author mainly introduces the influencing factors which need to be further considered, including the condensation of particles under the force of each other, the rebound of particles and the influence of particle’s own properties.
