Well, now researchers have created some delicate water structures of their own, in the form of microscopic ice mazes, with a little help from light.

现在，研究人员在光的帮助下，创造出了他的微妙水结构，展现形式为微小的冰迷宫。

Everybody knows that when water flows to any sort of dirt, there are characteristic structures, there are other functions of that water running through.

大家都知道，当水流过任何一种土时，会留下有其特征的结构，水流淌过还有其他的作用。

If the reservoir gets too high and the service spillway can't release water  fast enough, this structure overflows, preventing the reservoir from reaching  and overtopping the crest of the dam.

如果水库太高并且服务溢洪道无法快地释放水，该结构就会溢出， 从而阻止水库到达并超过大坝的顶部。

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.

陆地上的动物， 像我可爱的狗狗珂润，可能会在泥地或者沙地上留下脚印，但海洋生物的脚印，据其形态， 我叫它尾流结构，或者水动力结构，这被包含于流体概念中。
