一、序言 喇曼散射法是激光分光测定技术中最为保险的一种方法。有关燃烧现场已有很多例证。笔者们已经在火焰中进行了氮、氧分子的振动喇曼散射光测定,将实验结果与通过理论运算得到的光谱进行比较,说明可以同时决定温度和浓度。在这项研究中,把燃烧的主要生成物H_2O与CO_2作为新的测定对象,提出了几种利用喇曼散射光的温度测定方法,同时明确了测定法的特征及问题所在。
First, the preamble Raman scattering method is the most insurance laser spectrophotometry method. There are many examples of burning sites. The authors have performed vibrational Raman scattering light measurements of nitrogen and oxygen molecules in a flame and compared the experimental results with those obtained by theoretical calculations, indicating that temperature and concentration can be determined simultaneously. In this study, the main combustion products H_2O and CO_2 as a new measurement object, several temperature measurement methods using Raman scattering light are proposed, and the characteristics and problems of the determination method are clarified.
