用X射线康普顿散射法测量了层流扩散火焰。温度分布由康普顿散射X射线强度的分析测量。化学状态分布由康普顿散射X射线光谱分析（s-参数分析）获得。康普顿散射X射线谱的强度和s参数分析表明，丙烷分子从圆柱形本生灯崩溃立即符合碳烟的产生。此外，温度升高到1500 K，并在燃烧场产生大量的CO2。我们的研究结果表明，康普顿散射X射线分析可以是一种新的无损测量的温度和化学状态的燃烧反应。
A laminar diffusion flame was measured by X-ray Compton scattering. The temperature distribution was measured from an analysis of Compton scattered X-ray intensity. The chemical state distribution was obtained from a Compton scattered X-ray spectrum analysis (s-parameter analysis). The analysis of intensity and s-parameter of Compton scattered X-ray spectra indicate that the propane molecule emitted from the cylindrical Bunsen burner collapse immediately coincides with soot generation. Furthermore, the temperature increases up to 1500 K and a large amount of CO2 was generated at the combustion field. Our results show that the Compton scattered X-ray analysis can be a novel nondestructive measurement for temperature and chemical states in a combustion reaction.
