Summary: | The invention belongs to the technical field of particulate matter monitoring, and relates to a fine particulate matter mass concentration calculation method of a particle size spectrometer, which comprises the following steps: aiming at different scenes, respectively establishing a particle number-mass concentration conversion model of each scene; determining a weight ratio of a particle number-mass concentration conversion model of each scene based on the typical particle number ratio of each particle size section of each scene and the particle number of each particle size section in ambient air monitored by a particle size spectrometer in different time periods; determining a particle number-mass concentration conversion model of the particle size spectrometer based on the particle number-mass concentration conversion model of each scene and the weight ratio of the particle number-mass concentration conversion model of each scene; and determining the mass concentration of the fine particulate matters of th |
