摘　　要：介绍了基于可调谐半导体激光吸收光谱（TDLAS）的气体温度测量原理，选择了1对O2吸收谱线13163．78cm，和13164．18cm，理论计算了此谱线对线强比值R与温度的关系，在搭建的高温实验装置上实现了O2温度和浓度的同时测量，并分析了压力对温度测量的影响。实验结果表明：在823～1323K内，温度测量的线性误差为0．65％。最大波动为±15K，压力变化对温度测量的影响可忽略不计。The principle of gas temperature measurement based on tunable diode laser absorption spectroscopy （ TDLAS ） was introduced . A pair of oxygen absorption lines （13 163.78 cm^-1 and 13 164.18 cm^-1 ） was selected,and the relationship between temperature and the ratio of the linepair linestrength was calculated. With a high temperature experimental setup ,the oxygen temperature and concentration were measured simultaneously,and the influence of pressure on the temperature measurement was analyzed. Experimental results show that within the temperature range of 823 K- 1323 K,the linearity error and maximum fluctuation of temperature measurement were 0.65% and ± 15 K, respectively, and the influence of pressure on the temperature measurement was negligible.
