给出了气泡在海水表面破裂产生的喷射液滴的生成参数。这份报告补充了之前的一份报告，提供了出生时间和所有喷气式飞机的高度，而不仅仅是顶部。给出了等效体积半径为350 ~ 1500 μm的气泡尺寸的计算结果。他们测量了气泡坍塌产生的喷射液滴的喷射速度、离地表的高度以及所有液滴脱离上升的射流的时间。对于本研究中使用的气泡大小，第一次释放的液滴，即顶部液滴，在诞生时最接近表面，第二次是最高的，所有随后的液滴都处于中间高度。此外，第二滴水之后的每滴水的高度都低于它之前的滴水。报告了10种气泡大小的射流滴的大小分布。它们与先前公布的尺寸分布不同，因为较低液滴的尺寸不是双峰分布的。这种差异归因于水温的不同。
The parameters of the births of jet drops originating from bubbles bursting on seawater surfaces are presented. This report supplements an earlier one by providing the birth times and heights of all the jet drops, not just the top. Results are given for bubble sizes from 350- to 1500-μm equivalent volume radius. The ejection speeds of the jet droplets generated by a collapsing bubble and the height above the surface, as well as the time, at which all the drops break off the ascending jet have been measured. For the bubble sizes used in this study, the first drop emitted, the top drop, is closest to the surface at birth, the second is the highest, and all subsequent drops are at intermediate heights. Furthermore, each drop after the second is born at a height that is lower than the drop that preceded it. Size distributions of the jet drops from each of 10 bubble sizes are reported. They differ from size distributions published earlier in that the sizes of the lower drops are not bimodally distributed. This difference is attributed to a difference in water temperature.
