| 摘 要： | 探讨了低表面张力液体的表面波波速与波长的关系,利用该液体的单个波峰性质与圆柱透镜性质相似的特点,提出了一种新的在特定波长范围内测量该液体相速度的方法,并通过模拟计算确定了该测量方法的适用范围,同时在实验室模拟了该模型,实验结果表明在一定范围内该测量方法具有较高的精度.模拟计算结果与理论计算结果的数据拟合程度较好,最大偏差不超过5%.

| Abstract: | The relationship of wave velocity to wavelength of surface wave of liquid with low surface tension was discussed.By using the similarity of wave crest to cylindrical lens,a new method for measuring the velocity of liquid phase wave in the range of specified wavelengths was proposed, its applicational scope was determined by means of simulation evaluation,and meantime,this model was simulated in the lab.The experimental result show that this measurement method possesses higher accuracy within certain range.The(agreement) of simulation and theoretical calculation results with each other is fairly good,maximum deviation being less than 5%. |
