本文从生产检验的需要出发,讨论了在电阻、弹性、长度(膨胀)等物理量的温度关系测量中,关于温度特性参数的计算方法和影响因素,并给出了平均温度系数、瞬时温度系数和温度常数相互间的关系。有关结果已在电阻、膨胀等物理量的测量中得到证实. Based on the need of production test, this paper discusses the calculation methods and influencing factors of temperature characteristic parameters in the measurement of temperature dependence of physical quantities such as resistance, elasticity and length (expansion), and gives the average temperature coefficient, instantaneous temperature coefficient and The relationship between temperature constants. The results have been confirmed in the measurement of physical quantities such as resistance and expansion.
