| 摘 要： | In this study, online water-soluble inorganic ions were detected to deduce the formation mechanism of secondary inorganic aerosol in Xianyang, China during wintertime. The dominant inorganic ions of sulfate(SO42-), nitrate(NO3-), and ammonium(NH4+)(the sum of those is abbreviated as SNA) accounted for 17%, 21%, and 12% of PM2.5mass, respectively.While the air quality deteriorated from excellent to poor grades, the precu...
