In Marine layer clouds, an abundance of small particles may also delay the onset of precipitation, which depends on cloud droplets colliding and coalescing into larger, heavier drops.
由于降水取决于云滴相互碰撞并凝聚成更大更重的水滴，海洋云层中若存在大量的微粒还会推迟降水的发生。

As a protective colloid, it can prevent droplets and particles from coalescing and agglomerating, thereby inhibiting formation of sediments.
作为防护胶体，它可能防止小滴和微粒凝结成块，从而抑制沉淀的形成。

When the film is deposited, some coalescing (the flowing together of resin particles) takes place. This action helps build film resistance and permits the formation of uniform films.
