用匹配渐近展开法计算了小振幅振荡波在密度和粘性不连续条件下传播时的传质速度。对于两层系统中的行波，发现界面处的速度是波的传播方向，当最上面的表面是自由的时，界面上的速度与界面上的速度方向相反。如果密度差很小，与内波有关的计算传输速度可能比从Longuet-Higgins(1953)的工作中获得的与面波有关的传输速度更重要。
The method of matched asymptotic expansions is employed to calculate the mass transport velocity due to small amplitude oscillatory waves propagating in conditions of density and viscosity discontinuities. For progressive waves in a two-layer system, it is found that the velocity at the interface is in the direction of wave propagation; when the uppermost surface is free, the velocity there is in the direction opposite to that at the interface. If the difference in the densities is small, the calculated transport velocity associated with an internal wave can be of more importance than that associated with the surface wave as obtained from the work of Longuet-Higgins (1953).
