| 摘 要： | 从理论和实验两方面分析了光谱线线宽随温度的变化规律.将HITRAN数据库中常温下的线强参数修正到了测量温度,进而得到合成校准光谱.将合成校准光谱和实验测得的光谱进行非线性最小二乘拟合,得到了不同温度下标准气体CO浓度.这种反演算法的浓度误差在常温下不超过5%,具有很高的精度,但随温度升高浓度误差逐渐增大.从残差光谱曲线... |

| Abstract: | The spectral line widths of theory and experiment are analyzed with different temperatures;the line strengths under room temperature in HITRAN database are corrected to measured temperature,and then synthetic spectra are calculated.With the nonlinear least squares fit between measured spectra and calibration spectra,standard gas concentrations of CO at different temperatures are obtained.The inversion concentration error of this algorithm at room temperature is less than 5% with high precision.But with the ... |
