利用电子束荧光技术对高超声速平板边界层中的扰动现象进行实验研究，实验在炮风洞中进行，自由流马赫数为7.8，单位长度雷诺数为3.5×107/m，测量了平均密度分布、脉动密度分布，并获得了湍流密度脉动的互相关分布和频谱分布。实验结果表明在过渡区中有序与随机现象并存。
Electron beam fluorescence technique was used to study the perturbation phenomenon in hypersonic slab boundary layer. The experiment was carried out in a gun hole with a free-flow Mach number of 7.8 and a unit length Reynolds number of 3.5 × 107 / m. The average density distribution , The pulsation density distribution and the cross-correlation distribution and spectrum distribution of the turbulent density pulsations were obtained. The experimental results show that the order and random phenomena coexist in the transition region.
