摘　　要：烃类燃料是具有较高能量、来源丰富的一类燃料,是各类发动机的主要燃料,故检测其燃烧的中间产物对准确了解发动机的燃烧机理从而帮助改进燃烧室设计和燃烧方式等有重要的指导作用。本文首先介绍烃类燃烧中间产物的种类以及传统的测量方法,然后重点对光谱学的测量方法进行综述,包括傅立叶红外光谱（FTIR）、激光诱导荧光技术（LIF）、相干反斯托克斯拉曼光谱（CARS）、和可调谐激光吸收光谱（TLAS）技术。通过对国内外相关课题组的研究成果进行分析,可知光谱技术应用于测量烃类燃烧的中间产物已获得很多成果。其中,TLAS技术在进行检测的过程中的优势显著,其对恶劣环境的适应能力最强,并且能达到较高的时间分辨率,具有良好的发展前景。总之,随着光谱技术和相关电子技术和检测技术的发展,利用光谱技术进行烃类燃烧过程的检测发展正盛,并从理论研究逐渐应用到实际测量中。Hydrocarbon （HC） fuel is widely used in various engines with high energy and abundant sources. HC fuel combustion process is complex and accompanied by the formation and transformation of a large number of combus- tion intermediates, which are increasingly concerned and studied. The detection of the combustion intermediates plays an important role in accurate understanding of the engine combustion mechanism, and thus helps to improve the com- bustion chamber designs and combustion methods. The species to be measured of HC combustion intermediates are in- troduced and traditional measurement methods are briefly reviewed. And key focus of the paper is on the summary of spectroscopic methods for intermediates measurement, including Fourier Transform Infrared Spectrometer （F-FIR） , La- ser-induced Fluorescence（LIF）, Coherent anti-Stokes Raman Scattering （CARS）, Degenerate Four Wave Mixing （DFWM） and Tunable Laser Absorption Spectroscopy （TLAS）. The research results, at home and abroad, show that many achievements have been made in the application of spectroscopic technology to detect intermediate products dur- ing HC combustion process. Among these spectroscopic detection techniques, TLAS has great advantages, such as compact and robust system configuration, strong adaptability to the harsh environment, high time resolution and simul- taneous measurement of multiple parameters, which make it have good development prospective. Overall, with the de- velopment of spectroscopic technology, related electronic technology and detection technology, the development of HC combustion detection using spectroscopic technology is flourishing from laboratory research to practical applica- tion.
