火星96GPR计划

火星演化模型表明，可能有大量的水以底冰的形式存在地下之下，这些位于中纬度可能１－２ｋｍ深的永冻层，构成比温暖干层更易使无线电波穿透的介质，ＧＰＲ系统按计划集成了火星９６气球的地表拖曳导绳中，用来探测这种永冻层，估计其深度和所存在的水量。我们开发了在试验导绳中了ＧＰＲ系统。它涉及测探工作所采用技术与工艺，能满足适应于火星９６飞行计划对重昨和体积的限制，以及对低温和抗冲击的要求。这项工作还为电磁相容性

横穿贝加尔湖山脉北部寒区的线性工程

The development of North Transbaikalye mineral resources (e. g. the Chiney deposit of iron titanium-vanadium-magnetite ores and Udokan copper deposits) is impossible without the establishment of industrial and transport infrastructure, one component of which are linear engineering constructions (drive railways, by-line auto roads, platform passages, protecting constructions, and others). However,on condition of spreading permafrost rocks this is conjugated with certain ecological risk just as from the transport network objects so for the objects themselves. A special attention is paid in the paper to considering of problems of projecting and constructing railways on the Udokan ridge.     

由ODP Leg191布设的海底井下宽频带地震仪系统

名为WP-2的新井下地震观测站由ODP Leg191成功地布设在西北太平洋海盆的ODP1179E钻孔。为了研究地球构造，WP-2台站被安置在一个独特的点位。两套宽频带地震仪用水泥固定在玄武岩层内，通过ROV号潜艇来驱动系统并检查系统的工作状态。ROV也用于回收初始数据。WP-2台站的地震噪声水平对地震观测而言是足够低的。     

土壤的冷生构造及其对阿拉斯加土地利用的意义

Cryogenic structure (patterns made by ice inclusions) in seasonally frozen and permafrost-af-fected soils result from ice formation during freezing. Analysis of cryogenic structures in soils is essential to our understanding of the cryogenic processes in soils and to formulating land use management interpretations. When soils freeze, the freezing front moves downward and attracts water moving upward resulting in mainly horizontal lenticular ice formation. Platy and lenticular soil structures form between ice lenses in upper active layer. The reticular soil structure usually forms above the permafrost table caused by freeze-back of the permafrost. The upward freeze-back resulted in platy soil structure and the volume changes following the annual freeze-thaw cycle resulted in vertical cracks. The combined result is an ice-net formation with mineral soils embedded in the ice net. The upper permafrost layer that used to be a part of the active layer has an ice content exceeding 50% due to repeated freeze-thaw cycles over time. The mineral soils appear in blocks embedded in an ice matrix. The permafrost layer that never experienced the freeze-thaw cycle often consists of alternate layers of thin ice lens and frozen soils with extreme hard consistence and has relatively lower ice content than the ice-rich layer of the upper permafrost. Ice contents and thaw settling potentials associated with each cryogenic structure should be considered in engineering and land use interpretations.
