本文建立了一种在波盆中产生定向聚焦波的实验方案。研究了方向范围、频率宽度和中心频率对波聚焦的影响。研究了波浪包传播过程中最大振幅的分布、时间序列和频谱的演化以及水面参数的变化。结果表明，聚焦波的特性受波的方向性影响显著，定向波的破缺判据与单向波的破缺判据明显不同。
An experimental scheme for the generation of directional focusing waves in a wave basin is established in this paper. The effects of the directional range, frequency width and center frequency on the wave focusing are studied. The distribution of maximum amplitude and the evolution of time series and spectra during wave packet propagation and the variation of water surface parameters are extensively investigated. The results reveal that the characteristics of focusing waves are significantly influenced by wave directionality and that the breaking criteria for directional waves are distinctly different from those for unidirectional waves.
