This hydrodynamic finding could help engineers design systems that rapidly drain reservoirs, regardless of size.

这项流体动学发现也许有助于工程师们设计出何尺寸可快速排水蓄水池。

Known as the “lateral line, ”these sensors apparently act like a hydrodynamic antenna, picking up signals about the flow of water around them.

就像鱼侧线一样，这些扮演着水动天线角色传感器接收周水流信号。

And so a single scuba diver can go anywhere from the surface to 40 meters, or 120 feet deep, to measure the hydrodynamic signatures that organisms create.

这样潜水员就可以到达 水下40米以内何地方，120英尺何地方，去记录生物体留下流体学痕迹。

One might say he could see birds and flight if you look at his drawings of birds, or if you look at his drawings of water and hydrodynamics.

你看他画鸟、水或是流体学，就会觉得那些是真。

So, listen, do you remember when I said the similarities of the equations of general relativity and hydrodynamics suggest you could find the equivalent of Unruh radiation in a large body of water?

你还记得我跟你说过有关广义相对论与流体学方程中相似处表示了在有巨量水源地方很可能能找到盎鲁射线相似物？

And so terrestrial organisms, like my cute dog Kieran, might be leaving footprints behind in dirt or in sand, but marine organisms leave footprints in the form of what we call wake structures, or hydrodynamic signatures, in fluid.

陆地上动物们， 像我可爱狗狗珂润，可能会在泥地或者沙地上留下脚印，但海洋生物脚印，据其形态， 我们叫它尾流结构，或者水动结构，这被包含于流体概念中。
