摘要
本文在常功率平面热源法测定热绝缘材料a及λ的基础上,提出了一种用于测试液体导热系数的方法,并设计制造了测试装置。利用该装置测量了水、甘油、乙醇等液体的导热系数,获得满意的结果。
On the basis of the plane heat source method with constant power measuring the thermal diffusivity a and λ of insulating materials, this article put forward a new method and a measurement instrument designed and constructed by authors. The experiments measuring liquid sample of water, glycerine and ethanol were carried out in the temperature range from 3℃ to 50℃ with this instrument. Therefore, the satisfactory results were obtained.
