本文给出了深水中时间衰减重力波的新衰减率，其中考虑了空气中斯托克斯界面边界层中的能量耗散。这个包含空气阻力的衰减率可以用来推导由行进波引起的质量传输速度问题的一个新的“自由面”边界条件；对于浅水波，计算了两个特定的速度剖面，与Longuet-Higgins(1953)关于真空-水界面的相应剖面相比有很大的差别。
Abstract New rates of decay are presented for temporally-attenuated gravity waves in deep water, allowance being made for the energy dissipated in the Stokes interfacial boundary layer in the air. This decay-rate, involving air drag, may then be used to deduce a new “free-surface” boundary condition for the problem of the mass transport velocity due to progressive waves; for shallow-water waves, two specific velocity profiles are calculated, and indicate large differences in comparison with the corresponding profiles of Longuet-Higgins (1953) for a vacuum-water interface.
