英文摘要	在航空发动机燃烧室的研发过程中,传统的测量手段往往有时无法实施或不能满足精确捕捉流场信息的要求,发展新型、高精度测量以及先进诊断技术势在必行。重点介绍了适用于航空发动机燃烧室测量的先进激光测试技术,并与传统测量方法进行了比较。发动机燃烧室内的流场测量包括速度测量、温度和组分质量分数测量。氢氧根离子标记测速(HTV)方法适用于有化学反应流场的速度测量;而拉曼散射测量技术可以同时测量多种组分的质量分数和温度。利用这些激光测量技术的特点,可以使其在燃烧室的点火、贫油熄火及排放等性能的研究中发挥重要作用。; The traditional methods of measurement can't meet the requirements of accurate capturing of the flow field in the development process of the aeroengine combustor.Therefore,the development of high-precision measurement and diagnostic techniques was imperative.The advanced laser diagnostic tools suitabling for aeroengine combustor measurement were introduced importantly and compared with the traditional measurement methods.The flow field measurement in the combustor include the measurement of velocity,temperature,and species concentration.Hydroxyl Tagging Velocimetry(HTV) method is applicable to the velocity measurement in the chemical reaction flow field.Raman scattering technology can measure a variety of species concentrations and temperature simultaneously.The laser diagnostic technique would play an important role in the study of ignition,extinction,and pollutant emission characteristics of the aeroengine combustor.; 国家自然科学基金(11002125和51106131);中央高校基本科研业务费专项资金(2010121045);教育部留学人员启动资金(J20120104)资助
