研究了相分离二元液体混合物的液滴粗化的基本过程。对于稍微不对称的淬火，我们发现了两种新类型的粗化行为：（1）由二元碰撞后的形状弛豫与相邻液滴的几何构型之间的耦合效应引起的多重碰撞，以及（li）可能由碰撞扩散耦合引起的碰撞诱导碰撞。对于几乎对称的混合物，液滴密度如此之高，以至于我们可能需要考虑 Quid 系统特有的液滴粗化的新机制，该机制源于浓度和速度场的耦合
The elementary process of droplet coarsening has been studied for phase-separating binary liquid mixtures. For a slightly asymmetric quench, we have found two new types of coarsening behavior: (1) a muttipte collision caused by the coupling effect between the shape relaxation after binary collision and the geometrical configuration of neighboring droplets and (li) a collision indu-ced collision likely caused by collision-diffusion coupling. For a nearly symmetric mixture the droplet density is so high that we probably need to consider new mechanisms of droplet coarsening unique to Quid systems, which originate from the coupling be@veen concentration and velocity fieLds
