冰川移动

合成孔径雷达干涉差分测量（D-InSAR）技术是近几年发展起来的新技术，主要用于地面沉降、山体滑坡、冰川移动、火山活动、地震等地表微小形变的监测。

Differential interferometry on Synthetic Aperture Radar ( D-InSAR ) technique , as a new ground monitoring technology , can be used for the monitorings of earthquake , volcanic activity , glacial drift , land subsidence , landslide and other small surface deformation .

但社会文化的改变其实就像冰川移动般缓慢。

But cultural change often runs at a glacial pace .

所以水越多冰川移动的速度就更快

So , the more water there is , the faster the glacier flows .

印度官员认识到这种情况必须改变，该国也一直在以喜马拉雅山冰川移动般的速度缓慢开放。

Indian officialdom realizes this must change and , at the pace of a Himalayan glacier , has been opening up .

但是有时候，它们也会移动很快，有些地方的冰川移动速度甚至可以达到每年7000米。

But sometimes , they experience surges , and during these surges , in some places , they can move its speeds as high as 7000 meters per year .

呃，沉淀物就是一些像沙子、碎石、化石脆片等物质，由自然过程如风、流水或者冰川移动等进行转移。

Ah sediment as you know i s material like sand , gravel , fossil fragments that is transported by natural processes like wind , water flow or the movement of glaciers .

你们的教科书上把这种类型列为冰川移动的特殊类型，但是你们会看见…许多教科书把这部分省略掉了，不认为这是一种冰川移动。

You textbook includes this as type as a particular type of glacier movement , but you will see that these are ... cause many textbooks that omitted as type of movement as included .

那么这种速度往往是不寻常的，是一般冰川移动速度的100倍，尽管并不常见，你还可以看见冰川的移动。

Now , a speed like that are pretty unusual , 100 of times faster than the regular movement of glaciers , but you can actually see glacier move during these surges , though it is rare .

因此，冰块就会拉张或挤压，这就导致冰块破裂并重新形成表面的冰层，这些易碎的表面冰层的移动有时候就被看做是一种冰川移动，主要还是看融化源在哪里。

So , the ice would expand or constrict , and that can cause be crack to form in the surface of the layer of ice , and that brittle the surface ice moving , is sometimes considered a type of glacier movement depending on which source you can thaw to .

大陆冰川可以移动一样快33米，每一天。

Continental glaciers can move as fast as33 meters each day .

现在，你们也许已经知道了，冰川一般移动起来很慢。

Now , as you probably know , glaciers generally move really slowly .

从冰川鼻移动的定义出发，大部分冰川都在退缩。

A large majority of glaciers are in retreat , defined as the shifting of the snout .

现在，即便了解大型冰川如何移动或漂浮这个现象有些困难，而冰川其实是靠地心力来漂浮的已经不再是一个秘密。

Now , even though it may be difficult to understand how a huge mass less can move or flow , in another word for it , it 's really known that the secret that the glaciers flow , because of gravity .

他们发现在同样的14个月期间，冰层下湖泊溢出了1.7立方千米的水（相当于0.4立方英里），75公里（相当于45英里）长的伯德冰川的移动速度加快了10%。

They discovered that during the same 14-month period that 1.7 cubic kilometers ( 0.4 cubic miles ) of water cascaded through subglacial waterways , the 75-kilometer ( 45-mile ) long glacier downstream picked up speed , moving about 10 percent faster .

JakobshavnIsbrae是在我们星球上流动最快的冰川，移动速度一天可以达到14米。因为它的提前，它摧毁经过的一切，甚至在朝向大海时也切断了流经格陵兰伟大的山脉。

This , Jakobshavn Isbrae , is the fastest flowing glacier on our planet , moving as much as 14 meters a day . As it advances , it destroys everything in its pass , even cutting its way through Greenland 's great mountain ranges on its drive downwards towards the sea .

因此冰川往下坡移动时是没有冰块融化的。

And so the glacier oozes downhill without any ice actually melting .

而且温度也起到了一定的作用，因为冰川不会轻易的移动。

And temperature also plays part here , in that does not moves easily .

现在说一下影响冰川变形数量及冰川移动速度的几个因素。

Now , there are a couple of the factors that affects the amounts of deformation that takes place or the speed of the glaciers movement for example .

因此，在稍温暖地带的冰川，就会比更冰冷地带的冰川更容易移动。

So , if you had a glacier in the slightly warmer region , it will flow faster than the glacier in the cooler region .
