| 摘 要： | 作者在用摄影法进行坚直椭圆管内降膜波动实验研究时证实,当Re<400时,降膜内确实存在孤立波;R_(?)>400时,存在随机波.降膜中的孤立波是由小扰动发展而成的.实验结果与理论预测的孤立波特性吻合较好.

| Abstract: | Using the photographic method, authors confirmed experimentally the existence of solitary waves in the falling film inside a vertical elliptical pipe while Re number was below 400. There were stochastic waves for Re(?)400. The solitary wave in the falling film evolved from the small disturbances. The experimental results agree well with the theoretical results. |
