对反射激波与边界层相互作用时的激波分岔问题进行了实验和数值研究。该过程已通过彩色纹影照片可视化，清楚地显示了特征波形。伴随的压力测量暗示了波浪系统的三维特征。用基于欧拉方程的数值格式对问题进行了模拟，计算结果与观测结果吻合较好。
The problem of shock bifurcation observed for a reflected shock interacting with a boundary layer is investigated both experimentally and numerically. The process has been visualized by means of color schlieren photographs that clearly show the characteristic wave pattern. Accompanying pressure measurements hint at the three-dimensional character of the wave system. In a numerical scheme based on the Euler equations the problem has been simulated giving good agreement between the calculated and the observed wave configuration.
