A residue seemingly left behind by a flow of liquid.

看起来像是液体流过以后剩下的残余物。

Fluid mechanics is the description of the flow of liquids and gasses.

流体力学是对液体和气体流动的描述。

One idea is that these slope lineae could be formed by the flow of liquid water.

一种想法是，这些斜坡线可能是由液态水的流动形成的。

And by creating a network of these open-faced cubes and tunnels, scientists think they'll even be able to direct the flow of liquids through a system.

通过创建这些开面立方体和隧道的网络，科学家们认为他们甚至能够引导液体流过系统。
