摘要
分析了稳态平板导热系数测定仪的测量误差产生原因,对其测量原理进行了修正,并提出了修正公式,经过计算比较,用修正后的计算公式得出的结果更精确。
The reason of metrical errors of the stable flat measuring instrument for thermal conductivity was analyzed and the measuring principle was modified, then the calculating formula for thermal conductivity was put forward. The revised one was proved to be more accurate by calculating.
