2·This paper mainly discusses the tunnel construction technique in permafrost Soil on the plateau.
本文主要对高原冻土隧道的施工技术、工艺进行了试验研究。
3·Yakutsk is the largest city in the world built on permafrost - soil that remains permanently frozen year round.
雅库茨克是世界上建设在永久冻土上最大的城市——土壤在全年都保持冰冻。
4·The spacecraft will use its 2.5-meter robotic arm to scoop up soil samples and collect underground ice, or permafrost, to see whether there's evidence life ever existed on the Red Planet.
探测器将借助2.5米长的机械手臂挖掘土壤样本，采集地下冰，或者永久冻土，来研究这个红色星球上是否有生命迹象存在。
5·The researchers measured the retreat of the permafrost border byobserving hummocks known as "palsas, " which form naturally over icecontained in the soil of northern peat bogs.
研究人员通过观测被称为泥炭丘的小丘来测量永冻带边界北退的程度，泥炭丘是在北部泥炭沼泽含冰的土壤上自然形成的。
6·What's more, the ice doesn't quit at the level of the soil. It's also below the surface in places that do occasionally get sunlight — a kind of lunar permafrost, the scientists call it.
冰会存在于一定土层。在偶尔能照到太阳的表面下，科学家把它叫做一种月球冻土。
