| 摘 要： | 精确检测气体浓度在大气环境保护、工业生产控制、废气排放监测等领域有着迫切需求。可调谐二极管激光吸收光谱技术(TDLAS)是实现气体浓度精确检测的重要方法，然而温度变化却为浓度精确测量带来较大误差，因而对检测结果进行温度修正是十分必要的。本文从理论角度出发，阐述了TDLAS技术检测气体浓度的温度影响机理，重点分析并归纳了基于TDLAS技术的气体浓度测量的温度影响修正方法，并展望了其发展趋势。

| Abstract: | Accurate detection of gas concentration is in urgent demand in the fields of atmospheric environmental protection,industrial production control,and exhaust emission monitoring.Tunable diode laser absorption spectroscopy(TDLAS)is an important method for achieving accurate detection of gas concentration.However,temperature variations bring significant errors to the accurate measurement of concentration,making temperature correction of the results essential.In this paper,the mechanism of temperature influence of gas concentration detection by TDLAS technology is described and the temperature influence correction methods for gas concentration measurement based on TDLAS technology is focused on analyzing and summarizing,and the trend of its development is envisioned. |
