利用实时激光全息干涉法研究了水平偏置椭圆管的自然对流换热．同时分析了不同曲线拟合方法对数据整理的影响，提出了分段曲线拟合．得出了特定椭圆管局部换热系数的变化曲线，并与有关的理论解进行了比较和分析．
The Natural Convection Heat Transfer of a Horizontal Offset Elliptical Tube is Studied by Real Time Laser Holographic Interferometry. At the same time, the influence of different curve fitting methods on data collation is analyzed, and the piecewise curve fitting is proposed. The curve of the local heat transfer coefficient of a certain oval tube was obtained and compared with the theoretical solution.
