Acoustic instruments on the submarine told us that there was a ridge at the bottom of the ocean, sitting transverse to the flow of ice.
潜艇上的声波仪器告诉我们，在海洋底部有一道海脊，横向坐落在冰流方向上。
Dr Dutrieux said that the discovery of the ridge was an important piece in the jig-saw of factors that could be changing the ice dynamics in the region.
杜特·里奥博士说，海脊的发现是拼合可能改变该地区冰川动态的各种因素中的一个重要部分。
When the glacier became detached from the ridge, the ice flow was able to accelerate significantly.
当冰川和海脊分开，冰流速度就大大加快。
Today, along the ridge, climbers have the advantage of about 60 aluminum ladders to cross a treacherous ice fall and thousands of yards of fixed ropes.
现在，沿着山脊，登山者拥有了一些有利条件，包括跨越一条危险的冰瀑所架设的60多架铝梯以及几千码的已经布好的绳索。
Based on the previous research results related, the relationships between sand-ridge resistance, total resistance, ice-period resistance and water flow intensity are established respectively.
在前人研究的基础上，分别建立了沙垅阻力、总阻力、冰期阻力与水流强度间的关系。
