The Aerosol Mass Measurement Based on the Two-parameter Mathematical Model in Optical Sensor
نویسندگان
چکیده
On the basis of the analysis of random pulse signal, the mathematical model of the two-parameter random signal is established. Based on which, it is found that the random signal has a non-integer dimension fractal characteristics, and the fractal dimension is the ratio of the count distribution and the number of discrete degree ln σ . Besides, the mass distribution of the particle group is also a typical random distribution, and satisfies the lognormal distribution. Thereby, the functional relationship between the average quality and average voltage of the voltage is given, and a theoretical basis of the quality measurement by the light scattering counting particle is established. Finally, the physical meaning of the fractal dimension is proposed. Copyright © 2014 IFSA Publishing, S. L.

متن کاملInvestigating the relationship between ground-level particulate matter and aerosol optical depth during dust storm episodes: a case study of Tehran
Background and Objective: During the last few years, air pollution and increasing levels of particulate matters (PMs) have become major public health issues in the megacity of Tehran. The high cost of constructing and maintaining air pollution monitoring stations has made it difficult to achieve adequate spatial-temporal coverage of PM data over various regions. In this regard, the use of remot...
