摘要：
Based on the inverse problem theory of heat conduction, thermal conductivity of heat-insulation oil pipe coupling is researched in the paper. The finite volume method is extended to solve the direct problem, and the 0.618 method is used to solve the inverse problem by optimizing the objective function. The results show that by using the method, taking the outer wall's temperature as the sample indicators, the thermal conductivity and the temperature distribution of heat-insulation oil pipe coupling and the temperature distribution of heat-insulation oil pipe can be obtained easily and accurately.
