摘　　要：利用频闪光的水波投影设计制作了智能化水波演示装置,增强了水波的各种典型现象的演示效果,利用单片机使波动现象可控可调、持续稳定.使用该装置测量了表面张力波的波速与表面活性剂的关系、波速与波长的关系.An intelligent water＇wave demonstrator was designed based on projection with a strobe light. This apparatus with microcontroller could enhance the demonstration effect of the typical water-wave phenomena and make the fluctuation phenomenon controllable, adjustable and steady. The rela- tionship between the speed of capillary waves and surface active agents, wave speed and wave length was measured.

关 键 词：表面张力波 光学投影 频闪光 波速 波长
