| 摘 要： | 由于波浪作用下水质点周期性振荡运动的特性,对其运动轨迹的直接观测一直是比较困难的问题。然而对波浪作用下水质点运动轨迹的直接观测不仅有助于波浪理论的进一步发展,也有助于人们对波浪运动特性的客观理解。为此提出了一种成本极低的新型水质点示踪装置。该装置可直接观测波浪作用下的水质点运动,且结构简单、操作方便、环保安全,不影响水槽展开其他试验。结合系列水槽试验,详细讨论了该装置的工作原理和操作方法。试验结果充分表明,该装置与方法可以完成对不同波浪要素下水槽中任一水质点的示踪,试验数据符合波浪理论规律,证明了该装置的实用性和可靠性。

| Abstract: | Because of the characteristics of the periodic oscillatory motion of the water particles under wave action,the direct observation is difficult.However,the direct observation of the moving water particles under wave action is helpful not only to the further development of the wave theory,but also helps to understand the characteristics of the wave motion.So a new water particles tracing apparatus with a very low cost is presented.This environmentally-friendly and safe apparatus can be applied in observing the orbits of water particles directly,which is simple in structure and easy in operation,and without disrupting other flume experiments.Combined with a series of flume experiments,the working principle and operation method of the apparatus are discussed in detail.The experimental results also show that the apparatus and method are applicable in tracing any water particle in the flume under different wave elements,and the experimental data are in accordance with the wave theory,which proves the practicability and reliability of the apparatus. |
