Cracks and ice tunnels may be allowing some water to flow through; a bridge across the river downstream has been washed out from one water surge so far.

冰中自然形成的裂缝和隧道可能会允许一些河水流过去，而目前河下游的一座桥已经被河水冲击所侵蚀。

Long, sweeping flow lines are crossed in places by much shorter lines, which are deep cracks in the ice called crevasses.

在绵长蜿蜒的线条里有一些短得多的线，它们是一些很深的冰块的裂缝，称为冰隙。

Any cracks will alter the flow of heat, and these changes can be picked up with a heat-sensitive camera.

通过一台热敏感摄像机就能够捕捉到飞机上的裂痕，因为这些裂痕会改变热流的方向。

Hydraulic fracturing pumps many thousands of gallons of mainly water and sand, with a few chemicals, at high pressure into tight gas-bearing shale deposits (hardened muds), creating cracks that allow gas to flow back up the well to the surface ( Shale Shock).

Another early beneficiary might be Carbo Ceramics, which sells ceramic pellets the size of grains of sand that are pumped into the rock surrounding the wells to prop open the tiny cracks through which oil and gas flow.

To do so, fracking actually cracks the rock to allow for the natural gas to flow from the shale into the well.
