摘要：

Free surface waves were examined both in superfluids He and He with the premise that these inviscid media would represent ideal realizations for this fluid dynamics problem. The work in He is one of the first of its kind, but in He, it was possible to produce a much more complete set of data for meaningful comparison with theoretical models. Most measurements were performed at the zero temperature limit, meaning T < 100 mK for He-4 and T similar to 100 mu K for He-3. Dozens of surface wave resonances, including up to 11 overtones, were observed and monitored as the liquid depth in the cell was varied. Despite of the wealth of data, perfect agreement with the constructed theoretical models could not be achieved.
