  1. The paper introduces the fundamentals of the temperature distribution in the borehole drilled in the frozen formation, and discusses the ascertainment of these parameters, including the mass quantity of circulation medium, the coefficient of thermal conductivity of drilling rods, the coefficient of the intensity of heat exchange and the coefficient of unstable heat exchange between the rock and the circulation medium, and the rising of the temperature of the circulation medium in the bottom of the bore

    摘要介紹了凍土鉆孔內溫度分佈研究的理論基礎，其中主要討論了沖洗介質的質量流量、鉆桿桿壁的導熱系數、巖石同沖洗介質的熱交換強度系數與不穩定熱交換系數，以及孔底沖洗介質溫度升高值的確定。
  2. It is shown that the high hardness and low thermal conductivity promote the formation of transformed asbs, and the deformed asbs will form if low hardness and high thermal conductivity are involved ; for steel with both high hardness and thermal conductivity, the transformed asbs will transform into deformed ones, due to that the fast heat conduction from high temperature asbs results in rapid temperature rise around and thus decreasing the hardness

    研究結果表明：鋼的高硬度和低熱導率有利於形成相變帶；反之，則傾向于形成變帶；對于具有高硬度和高熱導率的鋼，由於高溫相變帶區域的熱量迅速傳遞到周圍的基體組織而使其溫度升高、硬度降底，形成的相變帶會向形變帶轉化。
  3. Abstract : the paper presents a theoretical study on the thermal conductivity of frost formation on cooled flat plate under forced convection. taking the porous meditum as a physical model of frost layer, according to the theories of heat and mass transfer, the formula on heat conductivty of frost formation is derived

    文摘:研究水蒸汽凝華結霜過程在冷壁上形成的霜層的導熱系數，依據隨機管子多孔介質霜層模型，假設霜層是由孔隙空間與冰晶骨架構成的多孔介質，其中孔隙空間由隨機毛細管及連接管子的接頭形成，濕空氣中的水蒸汽在霜層的孔隙空間中擴散輸運並凝華結霜，根據傳熱傳質學理論，導出霜層導熱系數關系式。
  4. Abstract : the paper presents a experimental study on thermal conductivity of frost formation through sublimation of water vapor. the experinmentals shows the results in reference 4 is curect
