冰脊

The crystal profile of the ice core (its length is 4.86 m) located at 74°58.614′N, 160°31.830′W shows the evidence of an ice ridge changed into hummock.

由位于北冰洋74°58.614′N，160°31.830′W，长4.86 m的冰心样的晶体结构分析发现它过去为冰脊，后经融化-冻结改造形成冰丘的证据。

AIRSS calls for reducing the ice multiplier values by one if the concentration of ice exceeds 0.6 and 30% of that ice is ridged (Transport Canada 1998), indicating the occurrence of ice pressure.

如果冰的浓度超过了0.6，30%的冰形成冰脊（加拿大运输部，1998），这意味着冰压力的出现时，AIRSS要求把冰的乘数值减少一。

The glacial heritages of this period interspersed most wildly, such as glacial valleys, cirques, horns, knife-edge crest, morainic boulder, end moraine bars, lateral moraine bars, morainic platforms, morainic hills, morainic lakes and glacial lakes, they are the most magnificent glacial landform heritages in the geopark.

该次冰期遗迹在区内分布最广，冰蚀槽谷、冰斗、角峰、刃脊、冰碛漂砾，终碛垅，侧碛垅，冰碛平台，冰碛丘陵，冰碛湖，冰川湖遍布，构成区内最壮观的冰川地貌遗迹。

The tidal sand ridges in the East China Sea and the sand ridges in the Celtic Sea are all large-scale and deep water sand ridegs on open continental shelf, and were formed in the postglacial sea level rise period.

东海潮流沙脊与凯尔特海沙脊均为开阔陆架上的大型深水沙脊，它们都形成在冰后期海面上升时期。

However, the historical ice data from Environment Canada only indicates ridging and does not quantify it.

然而，从加拿大环境部的历史冰层数据仅仅显示了冰脊的形成，并没有量化它。

Ice/ridge geometric parameters is established, and from computational analysis it is found that the unmonotonous variations of drag coefficient with ice concentration that frequently observed in sea ice field investigation mostly result from the influence of form drag from ice edge.

通过将原型条件下的冰-水总拖曳力考虑成表面摩拖曳力、冰侧形拖曳力和冰脊形拖曳力三部分，建立了冰-水总拖曳系数同海冰和冰脊几何形态参数之间的定量关系，并由计算分析发现现场观测到的拖曳系数随密集度的非单调变化就是冰侧形拖曳力分量作用的重要体现。

The job of reaching any new organisms at the ridge falls to scientists operating three new robotic vehicles, two of which are designed to navigate untethered under the ice.

在冰脊上抵达任何新生物的工作落到了科学家操作的三辆新的机器人车上，其中的二个设计成在冰层之下松梆航行。

From left: blocks of icy debris, warmed by the sun, tumble down cliffs of the northern ice cap; swirling dust devils leave tracks on defrosting dune surfaces in the south; as polar ice recedes, the surface erodes in scalloped ridges; during spring in the north, sand dunes emerge from the blanket of frost; starburst patterns are created as ice warms into gas and expands, creating channels spreading out radially; when the gas breaks through the ice, it creates plumes and material is carried downwind.

从左侧起依次是：冰碎块，由于被太阳加热，从北部冰帽的悬崖上滚落；漩涡状尘暴在南部解冻的沙丘表面留下的轨迹；消退过程中，极冰在地面侵蚀出圆齿状脊；在北部的春季，沙丘钻出&霜毯&；星暴图案是在冰融化成气体并不断扩散时形成的，在此过程中形成的沟槽呈放射状向外伸展；冰从固态变成气态时产生的气羽流顺风飘散。

The conversions of ice temperature and ice velocity occur from bridge to trough of terrain on the eastern Nyainqentanglha Range. The ice temperature at bridge is lower. The ice at bridge starts to move due to the larger gravitational driving stress. During the course from bridge to trough of terrain, basal ice temperature rises because of the friction. While reaching the pressure melting point of ice, basal decollement occurs, and higher velocities can still be produced at trough.

而位于念青唐古拉山东部地区的冰川，冰温和冰速从地形脊到地形槽处发生了较大的转化过程，在地形脊处冰温较低，受重力加速度的影响，冰川开始产生滑动，从地形脊到地形槽滑动的过程中，其底部受摩擦加热的影响，底部冰温升高，达到融化点，底部产生变形，到地形槽处仍会产生较大速度的滑动，因此冰川的运动从地形脊到地形槽处发生了转化，即地形脊处的滑动属动力过程引起的滑动，而地形槽处的滑动属热力过程产生的滑动。

Crossing miles and miles of sastrugi -- frozen ice snowdrifts that could be hip-deep.

穿越数英里的冰脊，冰雪齐臀深，带著170磅的雪橇在这样的情况下穿越，那雪橇会像1，700磅那麼重，因为感觉就是那麼重。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
