| 摘 要： | 本文将微扰展式方法用于研究非线性复合介质的传热情况．由于接触热阻的存在，势在两相界面上不再连续．研究表明，微扰展式方法也适用于研究相界面上势不连续的非线性系统．文中计算了含单个圆柱形杂质的复合介质的温度分布，并讨论了几种特殊情况．

| Abstract: | The perturbation expansion method is employed to study the heat transfer ofnonlinear composite media. Potentials on phase surfaces of composites are not continuous because of thermal contact resistance. The study shows that the perturbation expansion method is also applicable to the case of nonlinear system with potential discontinuity between different phases. As an example, we apply the method to calculate the temperature field of nonlinear composite media with an cylindrical inclusion embedded in a matrix and discuss several typical cases of temperature distribution in detail. |
