本文用双分解法分析了具有可变导热系数的环状双曲型翅片。二重分解法是解决非线性问题的一种有利方法。用二重分解法得到的解为无穷级数形式，并认为变量导热系数与温度呈线性关系。将精确模型解的结果与等导热系数情况下的结果进行了比较。确定了对翅片性能和温度分布有重要影响的参数。
In this article, the double decomposition method is used to analyze the annular hyperbolic profile fins with variable thermal conductivity. The double decomposition method is an advantageous way to solve the nonlinear problem. The solution gained by the double decomposition method is in the form of infinite power series, and the variable thermal conductivity is considered to have a linear relation with temperature. The results from the exact model solution are compared with the constant thermal conductivity case. The parameters that affect the fin performance and temperature distribution strongly are identified.
