摘　　要：以传热学理论为基础,根据物理模型自身的特点建立一维非稳态热传导模型,用于分析具有不同内外边界条件的热损失过程。开展物理模型边界热损失数值模拟研究,将对流换热模型和半解析无限厚盖层热损失模型与非稳态热传导模型进行对比分析。实例计算结果表明,对流换热模型与非稳态热传导模型模拟结果吻合较好。Based on the heat transfer theory, according to the unique feature of the scale physical model, the paper established one dimensional unsteady state heat conduction model and used it to analyze the heat loss process of the model with the different inner and outside boundary condition. The numerical simulation compared convection heat transfer model and semi-analytic infinite thick overburden heat loss model with the one dimensional unsteady state heat conduction model. The conclusion illustrated that the results of the convection heat transfer model and the one dimensional unsteady state heat conduction model obtained preferable coincidence.
