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。 -
The transition from negative to positive of the spherical function coefficient a20 reflects it impersonally and quantificationally. with ncep / ncar day - to - day height field analysis data, the coefficient of spherical function a02 is calculated. the transition dates of circulation type in middle stratosphere are determinated based on the dates that a02 have transited from negative to positive steadily
本文用ncep ncar北半球1958 1997年中平流層五層（ 10 、 20 、 30 、 50和70hpa ）逐日高度場再分析資料，計算出其球函數系數a _ 2 ~ 0 ，並據a _ 2 ~ 0穩定地由負轉正的日期確定了逐年中平流層各層環流轉型的日期，在此基礎上著重分析了春季中平流層環流轉型日期的氣候及異常規律及它們與平流層環流異常及與對流層環流的關系。 -
