【摘要】導(dǎo)熱系數(shù)測(cè)定儀(熱流計(jì)法)主要用于測(cè)定多種不同材料的導(dǎo)熱性能參數(shù),包括聚合物、陶瓷、復(fù)合材料、玻璃、橡膠以及部分金屬等,尤其適用于導(dǎo)熱系數(shù)處于較低至中等水平的材料。該儀器廣泛用于科研、工業(yè)生產(chǎn)、環(huán)境、建筑等領(lǐng)域。本文主要對(duì)該儀器的示值誤差測(cè)量結(jié)果的不確定度進(jìn)行討論。

Abstract: The thermal conductivity meter (heat flow meter method) is primarily used to determine the thermal conductivity parameters of various materials, including polymers, ceramics, composite materials, glass, rubber, and some metals, especially suitable for materials with low to moderate thermal conductivity coefficients. This instrument is widely used in fields such as scientific research, industrial production, environment, and construction. This article mainly discusses the uncertainty of the indicated value error measurement results of this instrument.
Keywords: thermal conductivity; indication error; uncertainty
