1·The frozen soils of the far north are already changing—from a tremendous storehouse of greenhouse gases to a tremendous source.
最远的北方冻土区也开始有了变化，从最大的温室气体储藏室变成了最大的温室气体源头。
2·The disease of subgrade in permafrost region was mainly induced by frost heaving and thawing circulation of frozen soils because of change of seasons.
多年冻土地区路基病害主要由冻土土体在季节变化条件下的冻融循环造成的。
3·The factors affecting the resistivity of frozen soils were discussed, and some solutions to grounding for lightning using grounding modules were introduced.
探讨了在多年冻土地区影响土壤电阻率的因素和使用低电阻接地模块降低接地电阻的工程方法。
4·The permafrost or seasonal frozen soils are undesirable engineering geologic condition and the frost heave and thawing settlement will influence the stability of foundations.
多年冻土和季节性冻土属于不良工程地质条件，其物理特性、力学和热学性能决定了冻胀和融沉工程病害对线路基础稳定性的影响程度。
5·Still modern archaeology, by applying appropriate techniques and comparative methods, aided by a few lucky finds from peat-bogs, deserts, and frozen soils, is able to fill up a good deal of the gap.
然而，现代考古学通过运用适当的技术和比较的方法，在从泥炭、沙漠和冻土中所获得的一些幸运发现的辅助下，能够填充这个空缺的很大部分。

7·Permafrost is underground soils containing ice which keep frozen for several years, it is remains of ancient glacial climate.
多年冻土是埋藏于地表下多年不融化的含冰土层，是古代冰川气候的残留物。
8·In the process of soils thawing, the settlement of soils is induced by the effect of self weight, because of the thawing in frozen layer of soils and the free dissipation of water.
冻土融化时，由于冻土层冰融化和水的自由消散，使土体在自重作用下产生下沉。
9·Water migration and variation in subgrade soils is the most active and live factor to the road frost damage in seasonally frozen ground regions.
在季节冻土区，路基水分迁移变化是道路冻害最积极活跃的因素。
