【Abstract】 In this context, according to the particle’s data that we meaured nearby the road surface in Beijing, we analysed the distriputing of particle’s granularity and the relationship between the distriputing of particle’s granularity and the structure of the street canyon? the distance from the ground. It shows the main factors that influence the distriputing of particle’s granularity.更多还原
