flow board cracks 流动痕迹
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.
