中文摘要：

对Brown凝并中两个不同直径纳米颗粒的碰撞系数进行了研究,通过求解碰撞方程,获得了在van der Waals力和弹性变形力作用下,直径为100 nm至750 nm的邻苯二甲酸二辛酯纳米颗粒的碰撞系数.发现碰撞系数总体上随着颗粒直径和2个颗粒半径比的增加而减小;当颗粒直径为550 nm时,碰撞系数有一个突然的增加.最后给出了具有不同直径2个纳米颗粒碰撞系数的新表达式.

英文摘要：

Collision efficiency of two nanoparticles with different diameters in the Brownian coagulation was investigated.The collision equations were solved to obtain the collision efficiency for the dioctyl phthalate nanoparticle with diameter changing from 100 nm to 750 nm in the presence of van der Waals force and elastic deformation force.It is found that the collision efficiency decreases as a whole with the increase of both the particle diameter and radius ratio of two particles.There exists an abrupt increase in the collision efficiency when the particle diameter is equal to 550 nm.Finally a new expression for the collision efficiency of two nanoparticles with different diameters was presented.
