Conditions of general aerosols during burning of a candle on January 5-6: (a) ratio of the number concentration of aerosol particles smaller than 10 nm ( 𝐶 N g e n (<10)) to that of bigger ones ( 𝐶 N g e n (>10)) and ratio of the total surface area of all particles smaller than 10 nm ( 𝑆 g e n (<10)) to the total surface area of all particles bigger than 10 nm ( 𝑆 g e n (>10)) in a volume unit and (b) ratio of the number concentration of aerosol particles smaller than 20 nm ( 𝐶 N g e n (<20)) to that of bigger ones ( 𝐶 N g e n (>20)) and ratio of the total surface area of all particles smaller than 20 nm ( 𝑆 g e n (<20)) to the total surface area of all particles bigger than 20 nm ( 𝑆 g e n (>20)) in a volume unit.
