摘　　要：论述了LFA447型扩散法导热仪的测量原理和实验过程,同时对影响误差的因素进行了分析,并用校核实验和重复性实验验证了装置的准确性和精确性。用此仪器对轮胎6种胶料的热扩散系数进行了测量,结果表明,在测量温度范围内,实验结果与温度线性相关。Measurement principle and experimental course of the thermal conductivity equipment were described. The effect factors of error were analyzed, and the accuracy and precision were verified by checkout experiment and repetition experiment. Six kinds of tire rubber were measured by using the equipment. Within the range of examined temperature, the results linearly depended on the temperature.
