摘要：

An aerosol is an assembly of liquid or solid particles, which are suspended in a gaseous medium to allow observation and measurement. The atmospheric aerosol describes a system of particles suspended in the atmosphere and they have a significant effect on health and climate. These effects are influenced by the chemical and physical properties of the aerosol particles, which makes these properties important to be measured. Many field observation have been performed with measurements with the Aerodyne aerosol mass spectrometer, which provides online, quantitative measurements of the total mass an size distributed nonrefractory chemical composition of the submicron ambient aerosol at a high temperature resolution. Primary aerosol constituents do not contain soot, and form as a result of a decrease in temperature of the exhaust gas without modification of gaseous precursors by chemical reaction, and thereby have to be regarded as primary aerosol.
