自然环境中非人为产生的气溶胶是最常见的云凝结核。
Natural aerosols are the most common condensation nuclei in pristine environments.
这意味着其他化合物也很重要——反之而言，当今假设以硫酸与氨构成云凝结核的气候模型，还需要作出修改。
That suggests other compounds are important, too-and this, in turn, implies that current climate models, which assume most seeds are made of ammonia or sulphuric acid, may require revision.
同时，因为它们是小液滴和冰晶形成需要的凝结核，因此尘埃微粒还能在云微物理学层面给云层带来改变。
Aerosols also affect cloud microphysics because they act as nuclei around which water droplets or ice forms.
Charlson一直对给空气中的湿气冷凝成云提供凝结核的未知粒子存有疑惑。
Charlson had been puzzling over what unknown particles provide the nuclei on which moisture condenses, forming clouds.
在凝结核计数器中被计下的粒子，在天然云或雾的凝结中往往很不活化。
Particles which are counted in condensation nucleus counters are very often not activated in natural cloud or fog condensation.
