| 摘 要： | 通过自行设计的一台管嘴出流形态观察设备，考察管嘴出流形态与管嘴扁椭圆型横截面长短轴变化及压头的关系，摄像法记录了近管嘴的流体形态特征，发现近管嘴的流体具有梭形节形貌，节长与压头成正比，流体的横截面长短轴以铅直方向为轴线出现类似偏振波的正交扭转，初步讨论了此现象发生原因．

| Abstract: | By a self-designed rig for morphology observation of vertical water outflowing jet, therelationship of the morphology to both water head and axis change of the nozzle with a flat ellipse section was investigated, the outflowing jet morphology was photographed by a camera. The outflowing jet near the outlet shows 2~3 pieces of shuttle-like divisions and an orthogonal axis alternation of the flat ellipse section around the vertical direction, and the division length is proportional to water head. The cause of the phenomenon was discussed briefly. |
