燃烧:一个不息的话题--同步辐射单光子电离技术在燃烧研究中的应用

燃烧应用于工业、农业、交通运输、国防等各个领域，提供了当今社会极大部分的能量需求。100多万年前人类就开始利用燃烧，人类研究燃烧已经有150多年的历史。本文介绍了将同步辐射真空紫外单光子电离技术结合分子束取样，应用于燃烧研究中，可以探测到燃烧中的各种中间物，包括稳定的和不稳定的产物。通过扫描光子能量，测量产物的光电离效率谱，可以区分其同分异构体，因此，利用这种新的诊断技术，在150年后的今天，我们仍然可以在火焰中发现很多新的燃烧中间体，为发展燃烧动力学模型提供精确的实验数据。最后，展望该方法在其它学科中的可能应用。

Combustion,a never extinguishing topic--Combustion study with synchrotron radiation single-photon ionization technique

Combustion is applied in industry,agriculture,transportation,and defenses et al.,which at present provides most of our worldwide energy support.Human began to utilize combustion about one million years ago,and they studied the combustion about 150 years ago.In this review article,we introduce a new technique,synchrotron radiation vacuum ultraviolet single-photon ionization combining with molecular-beam mass spectrometry,applied to combustion study.The new method can detect the flame intermediates including stable and unstable species.Isomers can be distinguished with measuring photoionization efficiency spectrum(PIE).Thus,new compounds can be found even after 150 years of flame research,which can be helpful to develop kinetic model.Finally,some other applications are prospected with this new technique.
