Fast mixing of fuel and air is one of the most important technical subjects to realize hypersonic air breathing engines. In order to measure instantaneous distribution of fuel mole fraction, we tried to develop a new technique using laser induced fluorescence signals of two tracer gases. We investigated fluorescent characteristics of several candidate matters and selected acetone and toluene as the tracer gas. We tested fluorescent characteristics of their mixture in air and other gases.

燃料与空气的快速混合是实现高超声速吸气式发动机的关键技术之一。为了测量燃料摩尔分数的瞬时分布，我们尝试发展了一种利用两种示踪气体的激光诱导荧光信号的新技术。考察了几种候选物质的荧光特性，选择丙酮和甲苯作为示踪气体。我们测试了它们的混合物在空气和其他气体中的荧光特性。
