摘要
为了把标准中温铂电阻温度计测出的电阻值准确地换算成温度值,广泛地采用作用函数法Ⅰ(列表法)。本文推导出适用于作用函数法Ⅱ的内插公式.按作用函数法Ⅱ算出的温度比作用函数法I算出的温度更加准确。并且按方法Ⅱ计算作用函数值时不会出错(有判别式可供检验)。
In order to convert the resistance-values measured with the stan- dard medium-temperature platinum resistance thermometers into accu- rate temperature-values,the effect-function method Ⅰ (Conversion ta- ble method) is adopted extensively.In this paper,internal insert formula for the effect-function method Ⅱ is deduced.The temperature- ualues calculated by the effect-function method Ⅱ is more accurate than that by the effect-function method Ⅰ.And when calculating values of the effect-function with method Ⅱ,discriminants can check errors if there any.
