cloud condensation nuclei

常见例句

Such crystals are thus efficient condensation nuclei and so promote precipitation from a cloud.
这种晶体是有效的凝聚核，从而促使云变雨降落。
In fact, most clouds owe their existence to aerosols that serve as the tiny “seeds,” called cloud condensation nuclei.
实际上，大多数云的形成都归功于气溶胶给了它们形成的小“种子”，科学的说法是云凝结核。
Some examples: plankton in the oceans release a gas (DMS) which oxidizes to produce submicroscopic aerosols of sulfate salts which form nuclei for the condensation of cloud droplets.
例如：海洋浮游生物释放出一种气体（二甲基硫），经氧化后产生亚微观的硫酸盐气雾，是为云中水滴凝聚的核心。
