粗颗粒物

冬季，TSP中约76%的气溶胶是细颗粒物；而春季，TSP中50%以上的的气溶胶分布在粗颗粒物中。

In winter , about 76 % of the aerosol in TSP were fine particules ; while more than 50 % of aerosol in TSP was coarse mode in spring .

这个读数是对细颗粒物PM2.5、较粗颗粒物PM10，以及臭氧、硫磺、碳和二氧化氮水平的汇编。

The reading represents a compilation of fine particulate matter or PM 2.5 ; coarser particulate matter , or PM10 ; and ozone , sulphur , carbon and nitrogen dioxide levels .

河床上覆水体中溶解态磷、颗粒态磷及赋存于粗颗粒物上的磷所占比例皆随悬浮颗粒物浓度发生显著变化。

The proportions of dissolved phosphorus , particulate phosphorus and phosphorus existing in the coarse particles in overlying water change significantly with content of SS .

结果表明，大气中颗粒物在积聚态颗粒物（0.32~1.80μm）和粗颗粒物（3.2~10.0μm）处有2个明显的峰；

There were two obvious peaks in the places in the accumulation mode ( 0.32 ~ 1.80 μ m ) and the coarse mode ( 3.2 ~ 10.0 μ m ) atmospheric particles ;
