本文报道的工作表明，当一滴水进入一池水时，可以观察到两种不同的现象，这取决于进入液滴的直径和速度。在一种情况下，液滴引起飞溅，而在另一种情况下，液滴与池合并而没有飞溅，并且当液滴穿透表面时，其形成涡环。这两种现象的出现的特征在于弗劳德数和雷诺数的组合。
The work reported in this paper shows that when a drop of water enters a pool of water two different phenomena may be observed depending upon the diameter and velocity of the entering drop. In one case the drop causes a splash and in the other case the drop coalesces with the pool without a splash and as the drop penetrates the surface it forms a vortex ring. The occurrence of the existence of the two phenomena has been characterized by a combination of the Froude number and the Reynolds number.
