摘要
铜合金导电率的测量常会受到试样均匀度、环境温度及测试人员的影响。采用相对合成标准不确定度的评估方法,对用开尔文法测量铜合金导电率结果的不确定度进行了评估。
The measurement of electric-conductivity of copper alloy is usually influenced by the homogeneity of specimen, analyst and the environ mental temperature. We adopt the method of the relative composite standard uncertainty for estimating the uncertainty of copper alloy electric-conductivity measured by Kelvin method.
