Fine dust optical property determination method and fine dust analysis device

摘要

In order to achieve the above object, in one embodiment, in the method for the fine dust analysis apparatus to determine the optical characteristics of fine dust, the first fine dust concentration ( _{K e1 ) through the first light extinction coefficient (K e1 ) input in advance} calculating f _v1 ), and calculating a second fine dust concentration (f _vs1 ) _{through the first scattering coefficient (K sc1 ) input in advance;} measuring an error rate by comparing the first fine dust concentration (f _v1 ) and the second fine dust concentration (f _{vs1 ) value;} When the error rate is below a certain value, [Equation 1] The first absorption coefficient (Ka ₁ ) is calculated through Equation 1, and the database built in the fine dust analysis device and the first light extinction coefficient (Ke ₁ ), the first scattering coefficient (Ksc1), and the first outputting a source of fine dust and optical characteristics (scattering, absorption) through the absorption coefficient (Ka _{1 );} And, when the error rate exceeds a predetermined value, the first light extinction coefficient (K _e1 ) and the first scattering _{coefficient (K sc1} ) are the second light extinction coefficient (K _e2 ) and the second scattering _{coefficient (K sc2 )} ), calculate the second absorption coefficient (K _a2 ) through the second light extinction coefficient (K _e2 ) and the second scattering _{coefficient (K sc2} ), and the database built in the fine dust analysis device and The second light extinction coefficient (K _e2 ), the second scattering _{coefficient (K sc2} ), and the second absorption coefficient (K _a2 ) to determine the source and optical characteristics (scattering, absorption) of fine dust, fine dust A method for determining optical properties is provided.
