从理论上推导了迄今为止未观测到的具有纵向特征的表面波的存在，并预测了这些波的特性。与毛细波不同，纵波由表面弹性模量而非表面张力控制；它们伴随着水平而不是垂直的表面运动，并且它们与具有高耗散特性的液体流相关，导致快速阻尼。在正常实验条件下，毛细波和纵波是叠加的，但纵波通常衰减得更快，除非在高弹性模量下。
The existence of hitherto unobserved surface waves with a longitudinal character is deduced theoretically and the properties of these waves are predicted. In contrast to capillary waves, the longitudinal waves are governed by the surface elastic modulus rather than by surface tension; they are accompanied by a horizontal rather than by a vertical surface movement and they are connected with a liquid flow of a highly dissipative character causing a rapid damping. Under normal experimental conditions capillary waves and longitudinal waves are superimposed, but the longitudinal wave is usually damped out much more rapidly, except at high elastic modulus.
