| 摘 要： | 用热电偶测量恒热流条件下薄板的温度时,沿热电偶丝的热量导出将引起接触区域的温场畸变,从而产生导热误差。本文对该导热误差公式进行了详细推导,分析了影响导热误差的各种因素,并且提出了减小导热误差的方法。

| Abstract: | While the temperature of thin plates under the condition of constant heat flow is measured with thermocouples, errors will be introduced by the heat conduction of the thermocouples and temperature field changes will be introduced to the measured spots. A formula of such heat conduction error is derived, and analysis of the factors affecting the error and its reduction method are presented in this paper. |
