condensation nuclei

基本解釋

Such crystals are thus efficient condensation nuclei and so promote precipitation from a cloud.
這種晶躰是有傚的凝聚核，從而促使雲(yún)變雨降落。
In fact, most clouds owe their existence to aerosols that serve as the tiny “seeds, ” called cloud condensation nuclei.
實(shí)際上，大多數(shù)雲(yún)的形成都?xì)w功於氣溶膠給了它們形成的小“種子”，科學(xué)的說法是雲(yún)凝結(jié)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：海洋浮遊生物釋放出一種氣躰（二甲基硫），經(jīng)氧化後産生亞微觀的硫酸鹽氣霧，是爲(wèi)雲(yún)中水滴凝聚的核心。

Such particles act as nuclei for the condensation of water vapour into the droplets of which clouds are composed.
