摘　　要：建立了基于点热源比较瞬时法的热导率测量装置，该装置适合于非电解质和电解质溶液，并可以使实验快速进行。用该装置测定１２个原油馏分在不同温度下的热导率，克服了由于原油中存在极性组分而影响实验结果的困难。关联了馏分热导率与温度、以及馏分的平均分子量、密度、运动粘度和折射率等基本物理性质之间的关系，结果满意。An apparatus for the determination of the thermal conductivity was constructed on the basis of the transient method by using a thermistor, which can give rapid measurements and be applied to both nonelectrolytical and electrolytical solutions The thermal conductivities at different temperatures of 12 petroleum fractions were measured by this apparatus and the difficulty due to the existence of the polar components in the fractions was solved The correlations of the thermal conductivity against the temperature and the physical properties, namely, mean molecular weight, density, kinematic viscosity and refractive index, were also presented The results were satisfactory
