利用高速激光诱导荧光技术研究了在较宽的气速范围内，有无液体卷吸的下行环状气液两相流中液膜的波动结构。结果表明，波浪结构总是由两种类型的波，长寿命和短寿命的波与后者总是产生在长寿命的波的后坡。文中还描述了短寿波产生和演化的主要原因。
The wavy structure of liquid film in downward annular gas-liquid flow with and without liquid entrainment is examined for a wide range of gas velocities using high-speed laser-induced fluorescence technique. It is shown that the wavy structure is always represented by two types of waves, long-lived and short-lived waves with the latter always generated at the back slopes of the long-lived waves. Main regularities of short-lived wave generation and evolution are also described.
