Fuzzy Assessment Model for Evaluating the Influence of Airport Aviation Noise on the Neighboring Residents
With the increasing of flights in airports and the extension of airports,the noise problem of airport aviation becomes more and more prominent.The traditional method evaluates the airport aviation noise by using the value of noise compared with the national standard.This paper took the noise value and subjective reaction of the neighboring residents as the assessment factors,and presented a multi-grade fuzzy assessment model for evaluating the actual influence of aviation noise on the neighboring residents.This paper provided a new idea for assessing the influence of airport aviation noise.
OBJECTIVE ::: To establish a new method to discriminate Aaron's beard by Fourier transformation infrared spectrometry. ::: ::: ::: METHODS ::: Attenuation Reflection-Fourier transformation infrared spectrometry with clustering analysis was used to the identification of Aaron's beard. ::: ::: ::: RESULTS ::: There were obvious differences in Aaron's beard. The results are consistent with that of morphologic study. ::: ::: ::: CONCLUSION ::: This method is rapid, simple and economical, and can be used to the quality control.
