cloud condensation nuclei

基本解釋

Such crystals are thus efficient condensation nuclei and so promote precipitation from a cloud.
這種晶體是有效的凝聚核，從而促使云變雨降落。
In fact, most clouds owe their existence to aerosols that serve as the tiny “seeds,” called cloud condensation nuclei.
實際上，大多數(shù)云的形成都歸功于氣溶膠給了它們形成的小“種子”，科學的說法是云凝結核。
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：海洋浮游生物釋放出一種氣體（二甲基硫），經氧化后產生亞微觀的硫酸鹽氣霧，是為云中水滴凝聚的核心。
