气体超声波数据库的构建
The propagation of acoustic waves in gases depends on gas composition,pressure,temperature and acoustic firequency.This causes that acoustic absorption and speed of sound vary with frequency,which can be respectively described by gas acoustic absorption spectrum(GAAS)and gas sound speed spectrum(GSSS).From the opposed point of view,gas-coupled acoustic techniques for gas composition detection are based on measurements of attenuation and phase velocity(speed of sound)in the gas.As a result,it is critical to obtain and arrange information about the two kinds of spectrum for a wide range of molecular species.
