摘　　要：首次用二维多面体扫描镜测量了超音速氧碘化学激光器的二维增益分布，测得增益区沿气流方向较长，沿光腔高度方向靠近壁面的两侧存在明显的边界层效应，并且边界层的厚度随着远离喷管出口平面距离的增大而增加。D small-signal gain of a supersonic COIL by a scanning polyhedron mirror was got firstly in out laboratory. The small signal gain along flow direction changes very slow and drops in the near of upper and lower wall. The boundary lay is thicker wih the distance from the nozzle exit plane and the average thickness is about 4～8mm.
