这是导致“全球变暗”的主要原因之一。全球变暗的现象始于1970年，是空气中的浮质(悬浮微粒)增加所致。
It is a major reason for "global dimming", which has been caused by an increased amount of aerosols in the air since 1970.
这些大气微粒通过两种途径作用于冰川：首先，悬浮在空气中的微粒吸收太阳光，升高周围空气温度。
These particulates can melt ice in two ways. First, floating in the air, they absorb sunlight and heat the surrounding atmosphere.
这些微粒没有到达大气的最高层，并且不可能长时期悬浮在空气中而影响全球气候。
Those particles haven't reached the upper levels of the atmosphere and are unlikely to hang around for a long time or affect the global climate.
用云母核孔膜、扫描电子显微镜和微电子探针对工艺房间空气中悬浮的气溶胶进行了采集，并对气溶胶的粒径分布、微粒形态及结构、元素成分和捕集机制进行了研究。
Aerosols in the air of a workshop were collected with mica track filters, and the size distribution, shape, structure, elemental compositions and capture mechanisms of aerosols were studied.
