permafrost zone meaning in Chinese
冻上带
Examples
- Continuous permafrost zone
连续永久冻原带 - When a buried pipeline goes through permafrost zone , thermal action between medium in pipeline and permafrost occurs and causes the frozen earth thawing , so the thaw settlement forms around the pipeline
摘要埋地油气管道通过永冻土地带时，由于管内介质与周围的冻土发生了热力作用，使冰土解冻，在管道周围形成融化圈。 - There are three main genetic types : ( 1 ) biogas generated in high - latitude and low - temperature permafrost zone : ( 2 ) biogas generated in high salinity environment in high elevation ; ( 3 ) biogas in shallow pay generated in recent sediment
其主要成因类型有3种：高纬度低温，永久冻土带下形成生物气；高海拔、高盐度环境下形成生物气；现代沉积物形成浅层生物气。 - Taking an oil pipeline passing through permafrost as an example , the paper calculates and analyzes the positions and magnitudes of various maximum stresses , then put forwards the measures of reducing thermal deformation of pipeline in permafrost zone
还建立了理地管道模型，并以穿过永冻土地带土壤的输油管道为例，分析并计算了各种应力的最大值所在的位置和大小，提出了在永冻土地带减小管道热力变形的措施。
