摘要
本文分析了热线探针测定液体导热系数时产生误差的原因,指出了设计探针时应注意的问题。首次提出了利用实验数据对导热系数关联式进行校正的“两点式还原法”,从而提高了测量精度,与发表的文献数据相比,校正后的数据相对误差在±3%内。
The error-sources in measuring the liquid thermal conductivity with LSP are analyzed and the problems which should be paid attention to in LSP design are also suggested. A 'two points restoring method' ,which is for correcting the thermal conductivity corelation with experimental data, is developed and the preciseness of measurement is improved.The relation error of corrected data based on the published data are within ±3%。
