本文介绍了自补偿圆管法测定保温材料导热系数的原理、方法、实验装置及实测结果。测试结果表明，当采用固定功率补偿时，保温材料导热系数的原理误差不超过2％，该方法能满足工程测试要求。
This paper introduces the principle, method, experimental device and measured results of self-compensated pipe method for the determination of thermal conductivity of insulation materials. The test results show that when the fixed power compensation is adopted, the principle error of the thermal conductivity of the thermal insulation material does not exceed 2%. This method can meet the engineering test requirements.
