| 摘 要： | 提出一种仅需一台染料激光器即可同时测量火焰中氢和氧的CARS谱的新方法.取带宽为120cm~(-1).中心波长位于580.4nm的Stokes光束与532nm的泵浦光束相配合.同时测量氢扩散火焰中的氢和氧的CARS谱.用氢的S(6)和S(5)的积分强度比确定火焰中的温度并与氮的Q支CARS谱测量的温度和经过热损耗修正的热电偶测得的温度取得了相当好的一致结果.一次测出氢和氧的CARS谱.避免多次测量中参数的难以重复性.提高了以温度为参数来确定浓度的准确性.

| Abstract: | A new method of simultaneous H2 and O2 CARS measurement in a H2/air diffusion flame using a single dye laser was developed. The integral intensity ratio of S(6) and S(5) of H2 was utilized to determine the temperature. The agreement between temperatures measured by this new method and the conditional N2 CARS was satisfactory. Because the CARS of H2and O2measured simultaneously, this method presented a possibility that their concentration and flame temperature will be obtained in one run. |
