摘要
本文以Ar^+离子激光器的488nm谱线作为入射光束,测量了火焰燃烧时N_2分子的Raman光谱;研究了检测系统(双单色仪)的缝函数对测量结果的影响;进而以缝函数与Raman光谱辐射通量的卷积作为理论曲线,通过实验曲线与理论曲线的拟合,求得了气体的温度值。
The Raman scattering was excited by an Argon ion laser with wavelength of488 nm. Nitrogen was used as a proble molecule to determine the temperature ofgas-air flame. The value of the temperature was determined parametrically by thecurve-fitting procedures in which the experimental data were fitted to the calculatedspectral contours obtained from the convolution of theoratical radiant fluxwith the monochromator slit function. Also the slit function was determinedexperimentally.
