摘　　要：为了测量管状或者厚度不均匀的保温材料的导热系数,根据圆管导热仪的构造和原理,建立了导热仪模型和相关的测试系统,并通过试验测量了岩棉在不同温度条件下的导热系数,最后对试验结果进行了误差分析,结果证明了所建模型与试验装置的可靠性,所组建的导热仪可以快速有效地对圆管状材质的导热系数进行测试.In order to test thermal conductivity of the tube-form or non-uniform heat insulating materials, investigations have been carried out. A piece of measurement equipment has been built based on the tube-form method. Furthermore, the experiments, numerical value analysis and error analysis prove the feasibility of this method for testing thermal performance.
