This research has been achieved in order to quantify the long-term trend of the air quality in Beijing, China where the outstanding and historic development has undergone in the past 10 years at the beginning of the 21^<st> century. The average aerosol concentration in Beijing was approximately five times higher than those observed in several other cities in the world. The air quality in Beijing has not been improved during the past 10 years in terms of the aerosol pollution. Many regulations that have been applied to prevent the air quality in Beijing from the air pollution during the Olympic Games 2008 made the larger aerosols that have the particle size larger than 2.5μm reduced 25%, however it didn't work well for the reduction of much smaller aerosols that have the particle size smaller than 2.5μm.

这项研究是为了量化中国北京空气质量的长期趋势，在21世纪初，北京在过去10年中经历了突出的历史性发展。平均气溶胶。北京的空气质量比世界上其他几个城市高出约五倍。在气溶胶污染方面，北京的空气质量在过去10年里并没有得到改善。北京的空气污染质量2008 年奥运会期间，颗粒尺寸大于 2.5μm 的较大气溶胶减少了 25%，但对于颗粒尺寸小于 2.5μm 的较小气溶胶的减少效果不佳。
