摘要
用热电偶测量带电细丝温度时，由导热引起的误差是测量误差的一个主要原因，本文从理论上对导热误差进行了详细推导，分析了影响导热误差的因素．结果表明，为减小测量误差，须选用细热电偶丝作为测量工具．
The conduction error is a main reason of metering error while measuring the temper-ature of the fine line on-position by the thermocouple.In this paper,the conduction error is deduceddetailediy,the factor affecting the conduction error is analysed,the method reducing conduction er-ror is put forward.
