摘要
本文就遥感傅里叶变换红外吸收光谱进行气体组份的定量分析,作了比较深入的探讨。我们首次以靶机为例,作了遥感实测。测量靶机尾气的目的在于:模似真实的飞机,通过对发动机燃烧产物(尾气)的测定,为发动机燃烧效率提供实测数据,以便改进飞机发动机的结构。实验结果表明,遥感傅里叶变换红外光谱法,具有以下优点:(1)无需取样,无需做样品的前处理;(2)可以对远距离的红外源(如焰火、工业气体排放等),作遥感直接测定;(3)可以对燃烧时间短、不稳定的红外源,作瞬时测量;(4)测量速度快,准确。
The quantitative method for the measurement of drone(aircraft)exhaust using remoteFourier transform infrared(FTIR)spectroscopy has been investigated. The purpose cf measurement of drone exhaust is to improve structure of aircraft engines. The experimentalresults show that remote sensing FTIR analysis has following advantages:(1)Such measurements would requiree no sampling, no sample handling and no prior knowledge of anticipated species;(2)Speed of measurement is fast, it may measure many transient or unstable IR sources;(3)It can make remote measurement. It is possible to measure the IR sources which can＇t be reached(for example industrial stack etc.). As a result, remote sensing FTIR spectroscopy is used in many studies.
